Watering a lawn in the evening may sound like a reasonable solution, but in fact, you are rather harmful to your lawn. The best time for watering is another time. And the right timing decides whether the lawn is healthy and thick, or full of mold and bare places.
At first glance, evening watering can act as a handy way to save water: the sun no longer burns, the temperatures drop and the water does not evaporate so much. But it is the cold and humid night that creates ideal conditions for spreading mold, root rot and other problems that do not testify to your lawn. What you save in the evening, it will later choose your lawn to axle damage.

When and how to water properly
The best time for watering the lawn is early in the morning, ideally between 4 and 8 hours. At this time, the soil is still cold, which minimizes evaporation, and at the same time it has the grass all day to dry. Dry leaves are less susceptible to molds and diseases that otherwise spread quickly in moisture and without sunlight. Better than everyday short watering is once or twice a week properly and deep. Such watering will support the growth of the roots downwards, where the moisture is more stable. The lawn then cope better with the drought IS fluctuations. You should apply approximately 15 liters of water per square meter. Just place a few cans on the lawn and measure before filling up to about 1.5 cm.

If you do not have time to get up and water manually, invest in automatic irrigation. You can program modern systems for early morning hours and equip them with humidity sensors, so the lawn gets exactly as much water as it needs and no more.
In the evening, the water stays on the surface of the lawn much longer. Without sunshine, it takes the leaves to dry until morning. And this is the ideal environment for growth of molds and mushrooms, such as brown spots, powdery mildew or rust. If this condition is repeated frequently, the consequences may be permanent. Excessive watering, especially in the evening, can further lead to waterlogging soil. It is then unable to release air to the roots, which leads to their rotting and dying of the whole plant. A typical symptom of waterlogging is musty odor, blue -gray turf or puddles after rain.
Moist lawns attract slugs, mosquitoes and other undesirable guests overnight. These pests not only damage the lawn with a taste, but also transmit diseases. If the lawn is also weak and wet, there is no way to defend them.
Final advice for a healthy lawn
Watering the lawn is not only a matter of water, but above all its proper timing. Forget the evening watering as a habit. Instead, focus on the morning routine that brings real benefits. Morning watering reduces the risk of diseases, helps maintain a healthy root system and ensures efficient use of water.
If you really have to water the evening, try to do it as soon as possible. Preferably always two to three hours before dark. And make sure that the lawn is generally in good shape, well aerated and fertilized.
Proper watering is the basis of a beautiful and durable lawn. Although technology and smart irrigation can help, a healthy lawn always starts with the right decision. And it starts in the morning.
