In the spring, a bright green lawn easily covers the landscape, requiring only regular mowing. But come summer, when the weather is hot and dry for a long time, the grass turns from a deep green carpet to grass with large brown spots. In some places it can even be a little crunchy. There is no water. Once moisture returns, healthy green foliage usually begins to grow again. If you want your lawn to stay lush and green all summer long, you'll likely need to water your lawn in addition to timing it properly to get the best results.
Start watering early
The best time to water your lawn is early in the morning, between 4:00 a.m. and 8:00 a.m. With cooler temperatures and minimal winds, water soaks deep into the soil and doesn't evaporate much. In addition, there is not as much demand for water in municipal systems during this period, which can affect the pressure. Watering at midday is less effective because evaporation is rapid and strong winds are more frequent. Winds can not only increase evaporation, but also carry water onto driveways, yards or streets, which quickly creates a lot of waste. If getting up for 4 hours and watering the lawn seems complicated, you can look into what watering systems are, which can be programmed to water when convenient.
Another benefit of watering early is that when the sun shines, the lawn grass stems dry out faster, reducing the chance of disease taking hold. Watering in the evening, when dew prevails, creates the conditions for fungal growth on grass blades that are wet overnight. If these fungi take hold and begin to kill the grass, no amount of watering will help.
Watering according to the condition of the lawn
Maximize the benefits of early morning watering by watering as needed by your lawn instead of on a schedule. Instead of watering 15 minutes a day, water when the lawn shows signs of drought. Blue-gray color and footprints left after you walk across the lawn are clear signs that your lawn needs water.
Aim to water your lawn grass deeply and infrequently to encourage deep root growth. Lawns with deep root systems can dig into the soil 30 cm or more to collect their water and nutrients. A healthy and green lawn needs 1-1.5 cm of water once every 7-10 days. Keep in mind that factors such as soil type, lawn type, and prevailing weather conditions greatly affect how much and how often you need to water. The herb can provide clues.
Most types of lawn grass can easily tolerate extended dry periods. They do this when they go into a state of rest above the surface of the earth. Although your lawn may look dead during a drought, the grass's root system is usually healthy and strong during dormancy. The lawn can withstand 4-6 weeks of drought, which may have little long-term effect. If water usage is limited or costly to you, your lawn may be able to remain unharmed at rest. Resist the urge to spray it lightly every now and then. Light watering is uneconomical and ineffective for turf. Trust that the lawn will turn green when the weather changes.
