When growing a lawn, nothing is more vital than moisture and warmness. Without warmth, there's no development and without moisture, development can't continue. Grass is capable of growing in wet soil, however doing so can attract insects, weeds and disease. Consequently, it is imperative to maintain moisture only, rather than an overly wet lawn. Frequency and mount of watering, timing, soil and temperature all affect how the lawn responds to moisture.
Watering the lawn during the beginning of warm temperatures in the summer is not needed. Permitting the lawn to go into slight water deficiency will in turn amplify rooting. It's usually time to start watering the lawn when grass turns a slightly lighter green shade in color. When watering, do so thoroughly to allow moisture to reach the roots. Try to refrain from frequent watering, as it will lead to weeds and low root structure.
When it comes to watering the lawn, grass needs about 3/4 to 1 inch of water per week to remain green and achieve new development. Throughout the summer, when temperatures are high, more frequent watering is often necessary.
Timing is important when making certain the lawn absorbs water effectively. Early mornings between 12 a.m. and 9 a.m. are the best times to water the lawn. By doing so, the soil and grass both have time to dry during the daytime sunlight. When watering at night, extra moisture is created, which in turn can lead to fungal diseases. Watering in the middle of the day causes the water to disperse before it reaches the grass roots. Therefore, morning watering is best.
When providing moisture to grass, soil plays an essential part. Regardless of the type of sod and seed, grass will not develop if the soil can't supply moisture and oxygen. Well-drained soil is best for growing grass. Oxygen can't be provided when soil that doesn't soak up water is being used, which is why quick-draining soils are a problem. Under these circumstances, the soil can supply oxygen but provides little moisture. Loams are best for lawns. Loams are identical amounts of sand, clay and organic substances.
During the summer months, the heat disperses moisture. As a consequence, lawns need to be watered more frequently. Failing to do so can cause soil to become dry, which leads to brown patches or yellow grass with bald patches. Using a sprinkler system is beneficial to ensure all areas of the lawn are evenly covered. Also, keep in mind that cool temperatures cause the grass to retain moisture.
