A beautiful and neat lawn is considered a real decoration of any site. This type of landscaping requires constant care, which consists of timely trimming, proper watering and feeding with special fertilizers. Modern equipment helps to cope with the tasks.
The irrigation system allows you to evenly distribute moisture on the surface of the lawn. Thanks to it, it is possible to avoid excessive waterlogging, which is accompanied by the appearance of unevenness in the green area. How to water the lawn? You will find the answer to this question in our material.
What does the automatic watering system consist of?
Modern sprayers in auto watering systems have many holes that promote uniform spraying of liquid. Thanks to them, it is possible to avoid washing out the top fertile layer.
What does the irrigation system consist of? It includes several items:
- sprinklers. For a small area, it is enough to use 4 to 6 moisture sprays;
- pumping station. It is the main object of automatic watering. Its power is calculated based on the area of the plot;
- cleaning filters. They allow you to purify water from various debris and harmful impurities;
- pressure regulators. These devices regulate the uniform flow of the stream during the watering process. This helps prevent soil from being washed away;
- solenoid valves. They are responsible for supplying and shutting off water;
- pipes. They are used to connect all elements together;
- controllers. These devices allow you to set the required mode and level of water flow.
“Water the lawn should be done in the first half of the day. At this time, the plant experiences accelerated metabolic processes.”
Several types of sprinklers are presented in specialized departments:
- static. They have a wide angle of inclination that evenly distributes water on the soil surface;
- rotary. These models are equipped with a turbine mechanism. It allows you to adjust the length of the jet and the flow of liquid;
- pulsed. They provide rotation of the jet over several meters.
Modern automatic irrigation systems are equipped with hidden sprinklers. They are hidden in the upper layers of the soil. For uniform moistening, it is necessary to use several types of sprinklers. The photo of watering the lawn shows the process of irrigating a green area.
The pumping station should be located near a water source. This will ensure maximum installation power.
The main requirement of this system is the presence of special filters. They prevent debris and sand particles from entering the cavity of the sprinklers.
The controllers must be installed near the electrical line. She provides uninterruptible power supply for the entire installation. The batteries (cable and wires) are located deep in the ground.
A special corrugated metal pipe will help prevent mechanical damage.
Self-installation of an automatic watering system
Making a lawn watering system with your own hands is quite simple. Before you begin the work process, you need to prepare everything necessary tools and elements for the construction of the installation. For this you will need:
- auto watering system plan;
- sprinklers. The number of sprayers is selected in accordance with the area of the land plot;
- solenoid valves;
- control unit;
- pipes;
- shovel;
- sharp knife;
- rope;
- building level;
- special paint for marking the territory;
When all the details are prepared, you can move on to the work process. It includes several main steps:
Site marking. For this they use water-based paint. This allows the pipeline to be positioned correctly according to plan. In addition, small pegs are installed and a rope is pulled, which helps to preserve correct angle tilt
Digging a trench for a pipeline system. If a drainage irrigation system is planned, then the depth of each trench should be about 50 cm. The angle of inclination will be 3 C. The diameter of the drainage well should not exceed 0.5 m. Pipeline connection.
Drainage well equipment. To do this, you will need a container with a depth of 0.1 to 0.25 m. It is fixed in the thickness of the earth.
Installation of the control unit. The wires are connected to the solenoid valves and the manifold assembly. Connection of the pumping station. Automatic irrigation system connection.
Testing the installation. Turning on the system beforehand helps to study the shortcomings of the installation. At this point, leaks may appear. Starting the system.
How much to water the lawn?
How many times a week should I water the green area? Experienced experts recommend irrigating the lawn depending on the speed of its drying. IN summer time this period is 4 times a week.
Photo of watering the lawn
A neat green lawn with lush grass requires regular maintenance, which takes a lot of time and effort. A lawn watering system that can operate according to a given program in automatic mode will help make this task easier.
The irrigation system is designed for complete watering of the lawn using the sprinkling method. Thanks to the sprayers, the soil is moistened evenly, without eroding the top fertile layer, the roots receive a sufficient amount of moisture, and the grass remains fresh and juicy throughout the season.
The irrigation system includes the following components:
- sprinklers that spray water;
- a pumping station that ensures stable pressure in the system;
- fine filters designed to trap foreign particles;
- pressure regulators - they are used when installing sprinklers different types to equalize the water pressure;
- solenoid valves that turn on and off the water supply to individual groups of sprinklers;
- HDPE pipes connecting system elements;
- controllers that control the entire system according to a given program.
Sprinklers are devices that spray water flowing through pipes in the form of small drops. When not in use, they are practically invisible on the surface of the lawn. When water is supplied, the sprinklers extend upward.
Sprinklers are:
- static having a strictly defined direction and spray angle;
- rotary, with a stream of water rotating due to an internal turbine;
- pulse, in which the water jet rotates using a built-in ratchet mechanism.
Static sprinklers are installed in areas where a strictly defined spray angle is required (usually along the edges of the lawn, along buildings, fences and paths). Rotary and pulse sprinklers have a certain spray radius; they are mounted in the center of the lawn in such a way that there are no unwatered areas.
Underground garden sprinkler
To ensure uniform watering of the entire surface of the lawn, sprinklers with different spray radii are used. They are connected through individual pressure regulators.
The pumping station is installed at a water source - a water supply system, a well or a well. The power and throughput of the pumping station are selected based on the size of the lawn and the required volumes of irrigation. The pumping station must be equipped with a fine filter to prevent sand, rust and other small impurities from entering the system.
If the area of the site is large, it is advisable to divide the sprinklers into separate groups that are turned on one by one. This way you can reduce the required power of pumping equipment and reduce purchasing costs. In this case, groups of sprinklers are switched on using solenoid valves controlled by a controller.
The controller and control unit are placed in a convenient place, connected to the electrical network and powered by the pumping station and solenoid valves. Control cables are laid hidden (underground) in a corrugated metal pipe.
Used as pipelines plastic pipes HDPE and connecting threaded fittings.
They assemble quickly and without use complex equipment, resistant to low temperatures, do not rot. The diameter of the pipes is selected based on the required throughput according to the calculation results.
When laying pipes at shallow depths, in a freezing layer of soil, drainage wells and drain valves are installed at the end of the system branches to drain the system and preserve it for a long time. winter period. Access to drainage wells should be simple and convenient.
You can also connect to the system trunk irrigation for trees/shrubs and drip irrigation for flower beds and flower beds. This type of irrigation is connected through a reducer, which reduces the water pressure. To prevent the irrigation system from operating in inclement weather, a rain sensor is included in the circuit - it is installed on open place and connect to the controller.
Note! The selection of components and assemblies for the irrigation system is carried out only after calculations have been completed and a sketch has been prepared.

Design and sketch of an irrigation system
To start designing, you need an accurate site plan indicating the dimensions and objects located on it. The plan must indicate paths, recreation areas, and buildings that should not fall into the irrigation area. When using combined automatic irrigation, it is necessary to designate large trees, bushes and flower beds to which root irrigation is applied.
The preparation of a project can be divided into stages.
Step 1. Watering zones. If the lawn is divided by paths or a recreation area, the total area must be divided into separate sections. Jets of water during irrigation should not cross their (sections of) boundaries.
Step 2. Capacity and pipe diameter. At this stage, it is necessary to determine the maximum and optimal throughput of all pipeline branches. First, find out the diameter of the supply pipe at the point of connection to the water supply and pumping station. To determine the throughput, you can use Table 1.
Table 1. Throughput of HDPE pipes depending on their diameter.
| Pipe outer diameter, mm | Water consumption, l/min. | Water consumption m3/hour |
|---|---|---|
| 20 | 15 | 0,9 |
| 25 | 30 | 1,8 |
| 32 | 50 | 3,0 |
| 40 | 80 | 4,8 |
| 50 | 120 | 7,2 |
| 63 | 190 | 11,4 |
If the lawn is divided into sections, the branching is done according to the collector pattern - this will ensure equal pressure on all branches of the pipeline. The diameter of the main pipe to the collector should be no larger than the diameter of the supply pipe, the diameter of the branches should be less than the main pipe.
Step 3. Select the number of sprinklers. First you need to determine the installation location of static sprinklers with a limited irrigation angle. They are installed in the corners of the lawn and along paths and objects, directing the spray pattern onto the lawn. It is convenient to mark the irrigation zone on the plan using a compass.
Then radial sprinklers, static or rotating, are distributed in the center of the site. The irrigation zone of each sprinkler is outlined with a compass on the plan. In this case, you can use sprinklers with different watering radii.
Step 4. Selecting sprinklers. Based on the sketch, suitable sprinklers are selected, taking into account the radius and angle of irrigation, and the diameter of the thread. In this case, you should take into account an error of 10-15% and choose sprinklers with a margin.
Step 5. Installation location of EM valves and controllers. A separate solenoid valve must be installed for each separately switched irrigation branch. If possible, they are installed in one place, this ensures ease of maintenance. Control controllers are located in a protected location, but at the same time care should be taken to ensure convenient access for control and programming.
Mark the position of the EM valves and controllers on the plan.
1. Controller at the entrance to the house.
2. Solenoid valve block.
3. Pumping station.
Step 6. Layout of pipelines. Pipe laying lines are marked on the plan, choosing the minimum length and number of turns. Branches are grouped whenever possible. The diameter of the pipes is consistent with the diameter of the sprinkler threads. Mark the pipes and necessary fittings on the plan.
Step 7. Selecting the performance of pumping equipment. When installing a pumping station, you need to coordinate its performance with the flow of water for irrigation. The total water consumption of all simultaneously operating sprinklers is determined, possible losses, which can reach 20%, are taken into account, and a pumping station is selected.
Step 8. Drainage wells. They are installed at the lowest points of the site. One or more branches of the pipeline are brought into the wells. The location of drainage wells must be chosen so that they are not conspicuous, but are easy to maintain. In the figure, the position of the wells is indicated in blue.
Step 8. Auxiliary equipment. Filters and shut-off valves are selected according to the parameters of the pipeline, and the location of their installation is marked on the plan. They are also designing the installation of rain and soil moisture sensors.
For ease of reading the drawing of the irrigation zone, you can highlight different colors, and also indicate the designations of elements using symbols.
Note! For convenience, simultaneously with the plan, a specification is drawn up, which includes the quantity and characteristics of the selected elements.
DIY lawn watering system installation
For self-installation Irrigation systems require electrical and plumbing skills. If they are absent, it is better to contact specialists. Step-by-step instruction installation and connection of an automatic lawn watering system is given below.
Step 1. Marking the lawn. Using special environmental paint or chalk filling, mark the location of the pipeline, installation of equipment and drainage wells according to the sketch. If the system is installed before laying the lawn, markings can be done using pegs and twine or warning tape.
Step 2. Preparation of trenches for the pipeline. Dig trenches of the required depth according to the markings. For a non-drainable system, pipes are laid below the freezing level of the soil - at a depth of at least 1 m. For a system with the ability to drain, a depth of 30-40 cm is sufficient, while it is necessary to maintain a slope of 1-3 degrees and equip each branch with a drainage well with a depth of at least 1 m, diameter – 0.3-0.4 m.
If the system is installed on an existing lawn, before excavating the soil, carefully cut the turf in layers or rolls and put it on a separate area. Rolls or sheets must be moistened regularly. The soil from the trenches is removed layer by layer with a shovel and put aside (on film) so as not to damage the rest of the lawn surface.
Step 3. Pipeline connection. Lay pipes of the selected diameter along the dug trenches. When temperature changes, the linear dimensions of HDPE pipes change, so installation is carried out without tension with a margin of 5-10% - this must be taken into account when cutting. Connect the pipeline sections using fittings according to the sketch. Carefully lay the pipeline at the bottom of the trench, observing the slope. To fix the pipeline, it is lightly sprinkled with soil at individual points.
Step 4. Equipment of drainage wells. For wells, use special containers or a pipe with a diameter of 0.3-0.4 m and a length of 1 m. It is dug in vertically, and the bottom is covered with crushed stone at a depth of 20-40 cm. The pipes are led into the well and closed with a shut-off valve. The top of the well is equipped with a lid.
Step 5. Installation of the manifold assembly and solenoid valves. The pipeline branches are connected through solenoid valves to the manifold assembly. The valves are installed near the pumping station in a convenient place for maintenance in protective boxes.
The valves are controlled from the controller; it can be installed either in a box or in a place convenient for control (in the second case, it is necessary to provide for laying a cable from the controller to a protective box with EM valves). The cable is laid in the ground in a protective pipe or corrugated metal sleeve.
Step 6. Connecting the pumping station. Pumping equipment is placed at the point of connection to the water supply or well in a protective box, caisson or inside the building. The pumping station connection diagram is shown in the figure.
Pumping stations can be equipped with an automatic control system; it prevents the pump from turning on in “dry running” mode and controls operating parameters. The automation unit can be placed directly on the pump body or in a separate control box. When installing a remote automation unit, it is convenient to combine it in one box with the irrigation system control controller.
Step 7. Connecting the irrigation system. The branches of the irrigation system are connected to solenoid valves mounted on the manifold. The main pipeline is connected to pumping station and a collector through a fine filter.
Step 8. Check and test run the system. Shut off all valves on drainage wells. Turn on the pumping station and dial required pressure in the hydraulic accumulator, after which the valve on the main pipe of the irrigation system is opened.
From the control unit, open the solenoid valves on each branch one by one and check all connections for leaks. During the inspection process, water flushes the system from foreign particles that entered the pipeline during installation.
Note! During test runs, it is recommended to reduce the pressure from the pumping station to the minimum rated value.
Step 9. Attaching sprinklers. Sprinklers are connected to the pipeline according to the sketch, while for static sprinklers it is necessary to observe the direction of spraying. Start the system again and check its performance.
Step 10. Backfilling the system with soil and laying the lawn. Carefully fill the pipelines with previously excavated soil, observing the slope of the pipes, and compact them layer by layer. The last layer is filled fertile soil with the addition of special lawn fertilizers. Pre-cut layers of turf are placed in place, watered and pressed. If necessary, reseed lawn grass.
Country cottage area developed, there is a garden, a vegetable garden, flower beds, and places for recreation. Lawns look attractive when the lawn is watered correctly and right time. If you leave a green area without maintenance, the grass will turn yellow, wither and resemble the vegetation of an abandoned wasteland. Everyone has seen the prohibitory signs “Do not walk on the lawns!” Such a ban is necessary in areas that are deprived of the owner’s attention. Of course, it is not recommended to organize a military parade rehearsal on the grass every day, and walking barefoot through pleasant, fresh greenery will not harm either the person or the vegetation.
How often should you water your lawn?
The lawn needs moisture throughout the entire summer season. Work begins with sowing seeds, and ends a week before the onset of cold weather. Exact dates and it is impossible to indicate the amount of water - all areas have different humidity and soil structure, weather conditions can change in the most unpredictable way. Much also depends on the type of plants planted: if white bentgrass cannot tolerate even the slightest thirst, then fescue will survive drought, and after rain the grass will continue to grow. It is undesirable to use this feature: dry leaves will no longer turn into fresh greens, and relaxing on a yellowed, half-dead lawn will not bring any joy.
If you think that the grass does not need artificial moisture, go to a clearing open to the sun’s rays after a severe drought. The vegetation there burns out to such an extent that even livestock avoids it. For novice gardeners who have no idea whether it is necessary to water the lawn and how to do it correctly, there are indicative recommendations. You can take them as a basis, then your observations will make adjustments to the overall scheme.
For middle zone Russia can adopt the following irrigation regime:
- in extreme heat and drought - daily;
- in hot weather on sandy soils - every 2-3 days;
- in summer in cool cloudy weather - weekly;
- in autumn - once every 10 days.
It is not advisable to shorten or increase the time between waterings. It is useless to heavily pour water on the lawn for 2 weekends in a row, and then leave it “on dry rations” for 5 working days. The soil should have time to dry before the next moistening. If you start irrigating wet soil, there will be no incentive for the roots to grow deeper; they will become located near the surface. With experience, you yourself will feel when the lawn needs watering, and in the first years the grass will remind you of its need for water. As soon as you notice even one sign of lack of moisture, moisturize your lawn and it will always look fresh.
The very first symptoms of drying out:
- the grass curls up;
- crushed greenery does not straighten out for a long time;
- areas where people walk begin to be trampled;
- the lawn has acquired a brown tint;
- plants look lethargic.
There are periods when plants need additional moisture.
- After mowing, carefully remove the cut fragments and water the lawn. Moisturizing will give it a fresh and clean look, will help you quickly recover from damage.
- When feeding, dry nutrients are not absorbed by the roots. Watering will help complete absorption of all components.
To ensure that the lawn has a neat appearance and nothing prevents young shoots from developing, comb the grass with a rake 2 times a season.
Do not water the lawn with water at a temperature below +10⁰ C, this is harmful to the root system. Water from a well or spring must be collected in a large container, where it will be heated in the sun.
How to water the lawn after planting seeds?
In the spring, the summer resident developed the soil, sowed the seeds and watered the future lawn. But if he doesn’t show up at the site for the entire working week, all the work can be considered in vain. The grains are located at a shallow depth, and soil exposed to the sun and wind dries out instantly. You need to water the lawn daily in the first ten days after planting the seeds. During this time, the grains will germinate and the roots will be able to take water from a depth of several centimeters.
Not every working person manages to get to the site every day. The earth will retain moisture longer if you cover it with film, a piece of rolled roofing or non-woven material. After emergence, the polyethylene and roofing felt should be removed, but the air-permeable covering can be left in place as long as it does not interfere with the growth of young grass.
Many information sources recommend covering the soil from drying out with a thick layer of mulch. This is a good option, but it is only suitable for plants that have already reached a height of 7-8 cm. If you fill the area with compost immediately after sowing, sprouts will not appear - they will not have enough light.
A mature lawn should be moistened not too often, but generously. But for young shoots such a scheme is disastrous. Water every 1-2 days, and in hot weather daily in small portions. If you pour too much water, a crust will form on the soil and the root system will not be able to get air. When the grass shades the ground, and the roots go deeper into the soil and form the soil structure, you can switch to rare and abundant watering.
How much water does it take to water a lawn well?
If you lightly wet your lawn at short intervals, nothing good will happen. Upper layer the soil will be constantly moist, and in the depths there will be dry soil. The root system will develop close to the surface and will not be able to take nutrients from the depths. Underground part will become very vulnerable, and if during a hot period you are not able to visit the site for several days, the grass will dry out.
Depending on the level groundwater, soil moisture and weather conditions for each square meter you need to pour out 20 to 40 liters of water. Multiply this volume by the area, and you will find out the approximate consumption on the territory of any lawn. The liquid should completely go into the soil; puddles and wetlands on the lawn are not needed. Some time after watering, check to what depth the moisture has penetrated. If the soil is saturated to 10 cm, it means there was enough water.
The time for watering also needs to be chosen correctly. Most the best option- early morning. Before the heat of the day sets in, moisture will be absorbed into the soil and the grass will dry out. At this time, a person cannot always get outside the city, so many summer residents are interested in the question: is it possible to water the lawn during the day? The recommendations for novice gardeners say not to. In the roast solar time this advice should be heeded: the droplets focus Sun rays, and burn marks appear on the greenery. But on cloudy days or cool autumn, you can moisten the lawn during the day. In the evening, it is advisable to finish work before 18:00 so that the greens dry before the cool of the night. When the air temperature drops, wet plants are often affected by fungal infections.
Mechanized watering of the site
A small lawn can be moistened manually with watering cans or a hose, but if the lawn occupies more than ten acres, you will have to hire a gardener for such care. Various devices that provide mechanical and automatic watering of the lawn will help make the work easier. The system can be laid over the entire area drip irrigation. The ground will be well saturated with moisture, but the grass will become dusty and lose its fresh appearance. Washing is necessary not only for animals, but also for plants; with this method, you will have to irrigate the plants from above from time to time.
For watering the lawn it is good to use:
- perforated hoses with holes along the entire length;
- sprinklers;
- circular sprinklers operating on the fountain principle;
- rotating and swinging sprinklers;
- automatic irrigation systems.
Watering with a perforated hose is not much easier than watering by hand. You need to lay out the tubes with holes on the lawn, moisten the area and move them to another place. Small sprinkler fountains are convenient in a small area, but if the lawn takes up large territory, you will need too many of them. Automatic irrigation systems are the most convenient option. You do not need to appear at the dacha; they turn on and off without human intervention. One drawback is that they are very expensive.
For country lawns Sprinklers work well. The rotating structure directs the jet in a circle. You can increase or decrease the diameter of the wetted area. Swinging models are convenient for rectangular and square lawns. It is advisable to plan lawns of the correct shape when laying out the site. Various protrusions and winding stripes look original, but then you will constantly have to run around with a watering can in secluded corners.
How to make a lawn watering system with your own hands?
You can purchase the necessary kit in the store, but you can make it yourself. To do this, you will need to purchase a pumping station, even if a central water supply is installed on the site. In the morning and evening, all gardeners begin to water their beds, and the water pressure may be too weak.
You will also need:
- plastic pipes;
- filters so that the holes do not become clogged with sediment from untreated water from the well;
- pressure regulators that allow you to provide different water pressure to individual areas;
- rotary or static sprinklers.
Before purchasing equipment, draw an accurate plan of your site. Consider how to place sprinklers to keep all lawns moist. Draw the pipes on the plan and calculate required amount. Several lawns with large area require complex system, allowing you to alternately turn on different sections of pipes. For this purpose, it is necessary to install shut-off valves on each branch, allowing you to open or shut off the water.
The system does not have to be buried below the freezing depth of the soil. If the pipes are laid with slight slope, and in the lowest point of the branch there is a device for draining water; a trench can be dug 30 cm deep. Install sprinklers, connect the pipes to the pumping station. Now you only need to turn on the system and the lawn will be watered.
Good home craftsmen can make automatic system equipped with controllers, solenoid valves, sensors, time relays. Thermal relay placed in a tank of water, when the temperature drops, the heater will turn on, the moisture for irrigation will always be warm enough. With such automation, you are not afraid of sudden severe frosts; the water will not turn into ice and will not burst the container. Special devices can monitor soil moisture, and in rainy weather the irrigation system will not turn on at the appointed time.
In the fall, after draining the water, blow out the entire system compressed air until no more moisture is released. This will save the pipes from rupture if liquid has accumulated in them.
The lawn is not a museum exhibit that can only be admired. You can walk on fresh grass and sunbathe on it. In order for plants to withstand these loads, they need proper care. A well-watered lawn will quickly return to its original appearance after your rest. If the greenery is trampled, empty seats, figure out your mistakes. Perhaps the soil is low in nutrients, waterlogged, or, conversely, too dry. Spare no effort, and the lawn will thank you. Contact of a naked body with grass is not only pleasant, but also beneficial for health, and bathing in the morning dew will replace expensive medicinal and cosmetic procedures.
Watering is one of the most important aspects of lawn care. Proper and timely irrigation will ensure beautiful view, stimulates plant growth and creates a favorable climate. With a lack of moisture, the growth process slows down, lawn grass turns yellow and begins to fade. It is necessary to water the lawn in spring, summer and autumn.
How do you know if your lawn needs watering?
If there is a lack of moisture, the grass itself will demonstrate this to you. It is better to get ahead of drying out by the first signs:
- The grass began to curl;
- The lawn began to be trampled, the grass takes a long time to rise after being pressed down;
- When there is drought, the grass turns brown;
- The grass withers or turns yellow;
- Bald spots appear.
Wilting is most noticeable on older grass. The first to suffer from drought are common bluegrass and white bentgrass. Average soil moisture requirements for meadow grass and chaff. Fescue trees are the least demanding.
When there is a lack of water, drought-resistant grasses remain alive. If their leaves and root system dry out, the plants go into dormancy mode. When the soil is moistened, it begins to grow again. Even though the herbs survived, appearance their performance during drought leaves much to be desired. A yellowed lawn is unlikely to be pleasing to the eye.
When is the best time to water the lawn?
The most common question is: when to water - in the morning or in the evening? Each case has its own characteristics and subtleties.
Watering is best done in the early morning. In cool, windless weather, water evaporates less and the grass has time to dry before the heat sets in.
Daytime watering is also acceptable, but it is worth considering that in the scorching sun, wet grass can get burned: drops of water create a lens effect. Wetting the grass in the heat is called harmful watering; spots appear on the blades of grass. Therefore, cloudy days or autumn period when the sun is less hot.
Evening watering in the summer is recommended to be done between 16.00 and 18.00. This is due to the fact that the grass needs to dry out. If the grass cover stays wet all night, this can negatively affect its condition and lead to fungal diseases.
How often should you water your lawn?
To accurately answer the question of how often you need to water your lawn, you need to consider the following factors: soil type, weather and root depth. The weather is the most important factor. In the driest hot summer weather, it is recommended to water every day. On average for Russia, in the heat and on sandy soils The lawn needs to be watered 2-3 times a week. In autumn and in cool weather, the rate of grass moistening is reduced to 1 time per 10 days. The main point that needs to be taken into account when watering is that the soil must have time to dry out between waterings. This will stimulate the growth of the root system: the roots begin to grow deeper, extracting the remaining moisture. In October, a week before frost, you should stop watering completely.
One of the most complex issues— how much water is required to water the lawn. For the middle zone there is a watering rate that ranges from 20 to 40 liters per 1 sq.m of lawn. Watering should be moderate. The formation of puddles and accumulation of water is unacceptable. The frequency of watering is determined by the composition of the soil and weather conditions. For light sandy loam soils, the frequency of irrigation is once every 3-4 days. For clay soils, once every 7-10 days. Additional moisture is provided after cutting, during the period of active growth and when feeding with fertilizers. Excessive watering of the lawn leads to overgrowth of moss and the development of fungal diseases.
If the lawn has been made recently and the grass has not yet sprouted, then the soil must be kept moist at all times. In this case, watering is required daily. Soil without vegetation and turf does not retain moisture, the dark surface of the earth heats up, and water quickly evaporates. On average, daily watering should be carried out for about 7-10 days. Further, the frequency of soil moisture is determined by the composition of the soil and the average daily temperature.
Types of irrigation
For young grass, or immediately after planting, you need a little water: the root system has not yet formed a layer of turf that absorbs and retains moisture. Therefore, you can water not a lot, but often.
Deep, abundant watering should be done during drought, in the summer.
Incorrect or harmful watering - usually this is oversaturation of the soil with moisture or wetting on a hot day. In both cases, the grass turns yellow and withers. Watering during drought is best done in the early morning.
Lawn watering products
Everyone chooses the means and methods of watering a green lawn themselves. Depending on the area of the lawn, the complexity of the terrain and its shape, you can consider the following options glaze:
A garden watering can is the easiest way to water your lawn with your own hands. Ideal for watering a small lawn near the house. You can’t do without a watering can to moisten problem areas, in places where the hose stream doesn’t reach or to avoid getting it wet again. garden paths.
Garden hoses are a simple and versatile method of watering. In combination with sprinkler attachments, it perfectly irrigates the soil, does not wash away the soil and does not damage root system. You can water the plants without using special nozzles, slightly blocking the stream with your finger. Due to the fact that watering is carried out with your own hands, the soil will be thoroughly moistened over the entire area. The downside is that you have to waste your time moving the hose with the nozzle across the lawn.
Perforated hoses differ from ordinary hoses only in that there are a lot of holes throughout their entire surface. The hose is deployed across the lawn, and quite large areas are watered through the holes.
The sprinkler is convenient device, turning a powerful stream from a hose into rain. The use of such a nozzle does not allow water to destroy the soil surface during irrigation. The disadvantage of the device is the large proportion of water evaporation during irrigation. Small particles of water are blown away by the wind.
The circular sprinkler looks like a fountain when in operation. They are usually installed in several pieces and are perfect for watering small lawns.
Rotating sprinkler - this device is a sprinkler with the ability to regulate the stream. This system Watering allows you to adjust the watering distance so as not to flood garden paths or swings.
An oscillating or oscillating sprinkler is designed specifically for watering rectangular and square shapes. The device allows you to adjust the range and degree of watering.
Automatic watering systems are used on large lawns when watering by hand takes a lot of time. The most important aspect is that irrigation systems are installed before the lawn is installed. There are two types of sprinklers used in these systems: stationary (or visible) and recessed. Recessed sprinklers appear on the surface of the lawn only when watering.
The automatic irrigation system consists of underground system pipes and hoses, sprinklers, large capacity water container, pumps, tensiometers, rain sensors and a computer. Tensiometers transmit information about soil moisture to a computer. Rain sensors report that there is no need for watering at the programmed time, if there is precipitation. Such systems are calculated and installed by specialists.
