10 tips for watering your lawn.

Watering the lawn

Watering the lawn should be done in the early morning or late evening, but not hot weather. Moisture from the lawn evaporates quickly in hot weather and this does not bring desired result, and plus this is extra water consumption. But do not forget that when watering during the day, the grass can be burned by the sun's rays.

The most important rule: it is better to water well once than many times and little by little.

Lawn, which for a long time not watered, on the contrary, you need to water little and often. Moisture should gradually saturate the soil.

Lawn grasses do not take cold water from a well or well very well. Many of my friends use water to water their lawns from reservoirs: swimming pools or driveways.

It is better to water the lawn not with a direct stream, but with sprinklers, and especially not to flood it. When watering with a direct stream, you wash away everything from the top layer of soil. useful material. And when watering with sprinklers, moisture gradually saturates the soil, while the plants take everything from the soil required amount moisture.

A new or reseeded lawn should be watered only with sprinklers, and never with a direct stream. Seeds embedded in the soil will be washed out with a direct stream and remain on its surface.

Watering the lawn under the trees. The lawn under the trees needs to be watered abundantly, because trees absorb moisture abundantly. But even here you should not overdo it, because if the crown is large and the rays of the sun do not warm the soil well, your lawn may simply turn sour. As a result, moss will appear in such an area and the grass will not grow well.

The interval between watering should be such that the moisture is completely absorbed and the grass dries out.

Evergreens in your lawn also require plenty of watering, especially in the fall and spring.

That's all! See you again!

Careful green lawn with succulent grass requires regular care, 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;
• filters fine cleaning designed to trap foreign particles;
• pressure regulators - they are used when installing sprinklers different types to equalize the water pressure;
• solenoid valves, turning 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 pipe, a well or a well. Power and Bandwidth pumping station selected based on the size of the lawn and the required watering volumes. The pumping station must be equipped with a fine filter to prevent sand, rust and other small impurities from entering the system.

At large area site, 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 pumping equipment and reduce acquisition 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 convenient place, connect to electrical network and power the pumping station and solenoid valves from it. Control cables are laid hidden (underground) in a corrugated metal pipe.

Used as pipelines plastic pipes HDPE and connecting threaded fittings.

They are assembled quickly and without the use of complex equipment, and are resistant to low temperature, 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 exact plan plot indicating the size and objects located on it. The plan must indicate paths, recreation areas, and buildings that should not fall into the irrigation area. With 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 seating area, total area needs to be divided into separate sections. Jets of water during irrigation should not cross their (sections of) boundaries.

Step 2. Bandwidth 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.

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 easy 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 are selected according to pipeline parameters and shut-off valves, mark on the plan the location of their installation. 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. Marked using a special environmental paint or chalk filling, location of pipeline laying, 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, in this case 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 linear dimensions HDPE pipes change, so laying is done 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 blocked 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 the pumping station and the collector through a fine filter.

Step 8. Check and test run the system. Close all valves on drainage wells. Turn on the pumping station and build up the required pressure in the hydraulic accumulator, after which open the valve on the main pipe of the irrigation system.

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 trial 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, sow lawn grass.

Maintaining a healthy lawn is a complex task that includes many activities. The most important of these is irrigation. But if you water your lawn at random, you can harm the plants.

The frequency of watering depends on a number of factors:

• irrigation purpose;
• soil type;
• weather;

According to the purpose of watering there are:

1. landing. It is carried out after or daily for 7-14 days in small doses. Freshly sown soil especially needs watering: having a black color, it is well heated by the sun and therefore quickly loses moisture;
2. vegetative. The main type of irrigation. Carry out throughout the warm season at intervals of every 3-10 days;
3. feeding. Lawns are watered after fertilizing;
4. supportive. Applies after ;
5. refreshing. It is used when necessary when air humidity is low;
6. moisture-charging. Its purpose is to saturate the soil with moisture. Mostly carried out in the fall, but sometimes required in the spring;
7. anti-frost. Apply in spring one day before frost.

Weather is taken into account as follows:

• hot dry: the lawn is watered daily;
• moderately hot: with accepted for of this type soil frequency (vegetation watering) - once every 3-10 days;
• during cool periods, for example in autumn: once every 10-15 days.

About a week before frost, stop watering the lawn (usually in October).

How important it is to stick to a proper watering schedule depends on the type of grass, here are some examples:

1. red, sheep's and tall fescue, perennial ryegrass: able to tolerate dry conditions for a long time;
2. chaff, meadow grass: medium hardiness;
3. white bentgrass, common bluegrass: tolerate only the shortest dry periods without consequences.

Plants of the first group are drought-resistant (with completely dry the above-ground part and roots do not die, falling into suspended animation). When the soil is moistened, they awaken and grow.

Signs that it’s time to water the lawn include:

• grass crushed by feet or wheels takes more than half an hour to recover;
• leaves are curled and bent;
• the color of the lawn has become dark green or bluish-gray, withered shoots are noticeable.

An important criterion: the soil must have time to dry out between waterings. The need to extract water from the depths forces root system develop.

Best time to water

Define best time The following analysis will help you water your plants:

1. Middle of a day. Watering the lawn during the day in clear weather leads to unpleasant consequences. The grass suffers from burns. Like glass lenses, water droplets focus sunlight, concentrating his energy on small area. An unreasonable amount of water is wasted. During the day, due to the heat, a significant part of the water evaporates and if a meter is installed on the water supply, the lawn owner incurs extra costs;
2. evening. Although the sun is no longer hot, evening watering is still undesirable: green carpet remains wet all night, which leads to the development of diseases. So that the grass has time to dry, water is supplied from 16-00 to 18-00, no later than;
3. morning. Perfect option, completely devoid of shortcomings.

Late evening watering is allowed only in extreme heat, when the temperature during the day exceeds 40 0 ​​C, and at night does not fall below 28. Water will prevent the plants from burning and at the same time, when heated by the sun, they will quickly dry out.

Norms for different soils

In addition to the frequency of watering, great importance has the amount of water supplied.

Deviations from the norm lead to undesirable consequences:

1. lack of moisture. Only the top layer of soil is saturated with water, which is why roots develop only here. The deeper the root system withers, because of this the plant weakens and loses its ability to tolerate drought. On average, grass roots reach a depth of 10-20 cm, some representatives go down to 50 cm. Therefore, it is recommended to maintain soil moisture at an acceptable level to a depth of 30 cm;
2. excess moisture. Puddles of water on the site contribute to the development of fungal diseases, grass rotting, and the lawn becomes waterlogged. Therefore, attempts to water the plants for future use are unacceptable.

Stagnation of water in a site due to excessive watering is not always observed - it depends on the type of soil. All types of soil are essentially a mixture of sand and clay, taken in different proportions. The higher the proportion of clay inclusions, the worse the soil absorbs moisture (low filtration).

Accordingly, on clayey area with an “overdose” of watering, there are puddles, while through sandy water, the water will simply seep through (high filtration) and go deeper. The latter, although it does not harm the plants, is also undesirable, since it causes excessive water consumption.

Puddles can also appear during normal watering if the area is not properly planned. In this case, unevenness is eliminated or a drain is organized.

Types of soil

Irrigation rates are determined not so much by the type of soil as by the climate:

• cool damp: water is supplied at the rate of 25 l/sq.m per week;
• hot dry: 50 l/sq.m per week.

The influence of soil type on the irrigation method is shown in the table:

On the site with clay soil It is useful to arrange a gravel-sand cushion: the soil is selected to a depth of 40 cm and successively layers of gravel and sand 10 cm thick are poured into the excavation. Each layer is compacted, and the extracted soil is poured on top of the cushion.

Tools and systems

You cannot water lawns with a stream of water, especially one supplied with significant pressure: the roots are exposed due to soil washing out, and there is a risk of damage to the stems.

The following methods are used:

1. sprinkling: Water is sprayed with a nozzle into small droplets that fall on the plants from above. The preferred method, since at the same time the grass is cleaned, and this makes the lawn look attractive. And when serving cold water small droplets have time to warm up during the fall, and the plant does not suffer from temperature shock;
2. drip poly c: moisture is supplied through drip tapes laid along the site (essentially perforated hoses) directly to the base of the stems. The method is used in narrow areas and others where the use of sprinklers covering a large area is unprofitable or impossible.

There are several types of sprinklers:

1. oscillatory. Design: short tube with several holes. The units are designed for servicing large lawns;
2. rotary. Spraying is carried out through a rotating head. The advantage is the adjustable irrigation radius. This makes the rotary sprinkler universal. It is suitable for any size lawn;
3. fan. Like rotary ones, they allow you to adjust the range of action. Easy to use and designed primarily for flat horizontal areas;
4. pulsating. Throw out water in a stream. Often used in combination with other sprinkler systems. Pulsing devices are more suitable for compact lawns. Advantage: the irrigation angle is set by the user, which allows the device to be used for watering corner areas of the site;
5. micro-sprinkling. The most gentle way. The water supplied through the nozzle is divided into many thin jets that are unable to damage even the thinnest and most delicate plants. Micro sprinklers are indispensable on lawns with.

Automatic watering

The passport of the irrigation installation indicates its productivity and range of action at various pressures, which allows you to calculate the required duration of irrigation. The productivity of drip tapes is usually indicated in l/h, of sprinklers - in l/min.

Let's look at an example:

• the lawn is located in a region with an average climate in temperature and humidity: the watering rate is 40 l/m2 per week;
• soil - loamy: watering is carried out 3 times a week, therefore, at one time the required amount of water is 40/3 = 13.3 l/m2;
• a rotary sprinkler is used with the following characteristics (at a given pressure): service area - 80 m 2, productivity - 20 l/min.

The duration of watering in minutes will be: T = (13.3 * 80) / 20 = 53.2 minutes. When using homemade sprinklers, their performance is determined by placing 0.5 liter cans around the area and then measuring the height of the water accumulated in them.

Converting the height of the water column to specific volume is simple: if after an hour 10 mm of water has accumulated in the jar, then the specific volume of irrigation is 10 l/m2. At the same time, this test allows you to determine the uniformity of watering.

Automatic watering systems are the most convenient to use. They are equipped with a programmable controller and two types of sensors: weather and soil moisture.

User participation is required only once: he enters data on the frequency, time and duration of watering. Then the system functions independently, monitoring the degree of soil moisture and canceling watering in rainy weather.

The most expensive models are equipped with retractable sprinklers: when not in use, they do not interfere with lawn care and do not spoil its appearance. An automatic irrigation system saves not only the owner’s time and effort, but also water, using it with maximum rationality.

The most durable systems with polyethylene pipes on compression fittings. Irrigation systems Gardena, Hunter, ClaberRain BirdToro, MetzerplasIrritrol have proven themselves well.

How to properly water a lawn:

At proper watering the lawn will be healthy and attractive. If the above recommendations are neglected, this will immediately affect the appearance of the lawn. To waste a minimum amount of water, it is advisable to purchase automatic system watering and do not mow the lawn too often or too short.

Like any other plant, lawn grass needs regular watering. And, like any plant, it will react to both an excess of moisture and a lack of it. Therefore, it is important to have an idea of ​​how to properly water your lawn. Of course, no one wants to stand with a hose in their hands and water it for hours, especially if you are only in the country for a few days.

You will not lose your precious hours of rest if your lawn is equipped with auto watering system. This means that your lawn is watered according to a predetermined program in the mode you select. The more expensive the automatic watering system, the more complex it is and, accordingly, “smarter”. Such a system will not water your lawn on rainy days, and with the help of sensors it will determine whether it needs to be watered or to postpone watering. And besides, it will water not just with water, pumping it directly from the well, but will take it from a storage tank, in which the water becomes a comfortable temperature for the grass. After all, you don’t water your cucumbers and tomatoes with cold water. tap water. In addition, all kinds of sprayers also help warm the water to ambient temperature.

The most comfortable water temperature for watering the lawn– this is 18º-20ºС, it can be lower, but not less than +10ºС. You can install an atopirrigation system yourself, but still, it is the specialists in this matter who will be able to develop a high-quality plan for covering all your areas, taking into account all the geometric features of the lawn, all zones and plants growing on it. Of course, there are automatic watering systems that are simpler and more affordable. But then be prepared to adjust both the watering time and frequency, and do not forget to turn off the automatic watering during rains. After all excess moisture can cause more significant harm than its deficiency. A lawn that is over-watered and lacks good drainage will look like it's already October in mid-summer. The soil does not have time to dry out, the roots do not breathe, they begin to rot, the grass turns yellow and droops, bald spots appear, and mushrooms begin to actively grow. Good conditions are created for the appearance of moss. Only powerful and strong grasses become active, which in nature tolerate waterlogging well, and hummocks form.

The most typical mistake owners of lawns with automatic watering is to increase the watering time on hot days. You should always let the sod dry out between waterings, no matter how hot it is. In extreme heat, the pattern of lawn growth and appearance changes for everyone; on lawns with automatic watering it is much better, but the most open areas and areas along the tiles still suffer. concrete paths. You definitely need to consider what kind of soil you have in your lawn and what types of grasses grow there. It is better to have a drought for a while than a flood. During drought, it is mainly the upper ground part of the grass that suffers, and then it quickly recovers again as soon as the rains come. After all, the root system of some cereals reaches a meter. Drought-resistant weeds such as clover and yarrow may flourish.

How to water your lawn if you don't have an automatic watering system? There is a wide variety of sprinklers and all kinds of “waterers” that will do this job for you. You will only need to periodically move the sprinkler to areas that have not yet been watered. If the lawn is large enough (5-8 acres), then it makes sense to purchase a hose system with several rotating sprinklers. Watering cans and holding the hose in your hands are the least suitable.

How often should you water your lawn? If the weather is normal summer without abnormal heat, with periodic rains, if the plants in your garden do not show signs of wilting or suffer, then there is no need to regularly water the lawn. If it rains rarely and there are other plants and trees on the site, then the lawn needs to be watered 2-3 times a week. Consider appearance grass (the lawn should be elastic and the grass shiny, without yellowing), the composition of the lawn mixture, the density of the grass, the presence of mature trees with a strong root system on the lawn, the composition of the soil on the lawn, air humidity, etc. and so on. Perhaps it will be enough for you to water once a week, or perhaps every day. Young and newly seeded lawns must be watered every day.

When to water the lawn? It is best to do this either in the morning from 6 to 9 am, or in the evening from 19 to 22 o'clock. If you water your lawn during the day, on a hot and sunny day, the bulk of the water will evaporate immediately during watering or on the grass, and drops of water can cause burns, acting like a lens under the sun's rays.

How much water does lawn grass need? Another common mistake is watering the lawn little by little and often. If you don’t have stationary waterers, be prepared for the fact that you will have to hold the hose in your hands for 2-3 hours to properly water even a piece of the lawn. It is better to water less often, but in sufficient quantity. How much water does your lawn need? And this can be calculated, especially since the moisture norm per 1 sq.m. known - it is 10-20 liters. It is this amount of water that will saturate the soil to the required depth of 15-20 cm.

How long should you water your lawn? If you place some container (a jar, for example) on the lawn and start watering, then after 12-13 mm of water has accumulated in the jar, it will mean that about 10 liters of water per meter have reached your lawn (at the watering site) sq. When there is 25 mm of water in the jar, that’s 20 liters of water for each pour. square meter. Record your time and estimate approximately how much time you need to spend watering your lawn.

Before you set up a lawn on your property, think about this important issue of watering. After all, you don’t want your material investment to go to waste. The lawn simply “must” be beautiful and well-groomed in order to please not only the eyes, but also your body. Walking on the lawn barefoot - what could be more pleasant and useful?

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 wither. 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. Despite the fact that the grasses survived, their appearance 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 summer time It is recommended to do it 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. 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 in 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 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 the lungs sandy loam soils Irrigation frequency - 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. Overwatering the lawn leads to overgrowing with 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
