One of the essentials of achieving a green lawn is right watering. Lack of water can lead to bald patches, browning, and even more weeds in the grass. However, excess watering too can cause problems such as weak grass roots, presence of too many weeds, and growth of mildew. Apart from the quantity and frequency of watering, you also need to ensure that the lawn is watered at the right time to avoid mildew formation. The best time for watering a lawn is at dawn. The lawn should be watered before the day gets hot, but leaving plenty of time for the extra water on the blades to be dried by the sun. This will ensure that there is a lower risk of mildew formation, even as most of the water is absorbed by the soil. The frequency of watering a lawn is determined by the season and weather conditions. In the hot months you might need to water the lawn twice a week, while in spring and fall it is sufficient to water the lawn once a week. You need to test the soil to see if it is dry before watering the lawn. For instance, in a humid week, or when it has rained, you can skip or delay watering if the soil is still damp. Frequent watering will damage the lawn as the root will not grow deep. Moreover, weeds are more likely to grow under such conditions. Each time you water your lawn you should aim to make certain that about one inch of water falls all over the lawn. This can be checked by installing sprinklers and also small measuring containers to check that one inch of water has fallen all over the lawn. If the water starts running off before you have completed watering it to the one inch level, you need to stop and wait for the water to be absorbed before continuing. You might also need to add mulch to the soil to increase its capacity to hold water. By watering the lawn properly, you will be able to reduce the frequency of watering, ensuring deeper root formation, healthier grass, less weeds, and less mildew formation. The most efficient way of watering your lawn is to install sprinklers with timers. Once the sprinklers have been installed, you need to check how long it takes to water the lawn with one inch of water and set the timer suitably. After that you can switch on the sprinkler in the early mornings the day after you find that the soil in the lawn has become dry. As with other plants, watering is a vital part of lawn care. However, you need to be aware of and follow the right watering methods to ensure that the lawn flourishes without weeds, insects, and mildew. By spacing the frequency of watering adequately you will help the grass develop stronger and deeper roots.
