Worst Time to Water Grass A Perfect Guide

Worst Time to Water Grass or Lawn

Watering your lawn may seem easy, but it’s not that simple. Only the one with the experience to keep a lawn green in the summertime knows the struggles. 

Watering too much in the daytime wastes water as it dries up due to sun heat. Watering too little turns your grass brown and dry. So, you must know how to save your lawn and money properly. 

Watering grass at night myth is followed by most of the people. But actually, that is just the opposite way. Water lawns at night or in the evening spreads diseases to your property. 

People often ask, will watering grass during the day burn it? If you water your lawn during the hottest period, which is between 11 AM and 4 PM, the water dries up instantly due to the humid weather. Your lawn will need water right away. So, it’s a waste.

Summer is the only season when too much watering needs. During the summer you need to water your lawn at least twice in a week. During the fall and spring, the environment tends to be cooler and need less watering. 

Why Watering at Night Considered to Be the Worst Idea?

People say they are saving water by watering their lawns at night. But you should just wait for the result before doing that on your own. Eventually, they will notice that they picked the worst time to water grass. 

Watering the grass to save water is not your goal. Your goal should be to give your grass their food, which is water. They absorb the water and create food with the help of the sun. That’s why watering in the daylight is necessary.

1. Disrupt Plant Activity 

Watering at night results in water soaking into the ground. The water doesn’t evaporate because there’s no sunlight. 

So, the extra water stays stuck at the bottom of the grass root. The pores or stomata of the leaves are open during the day for the transpiration process. 

But when you water your lawn at night, the pores can’t expel the moisture. As a result, the transpiration doesn’t happen. Because of that, your grass rots, becomes brown, and spreads diseases and other problems.

2. Waterlogging


Watering at night causes waterlogging into your lawn, which is a severe problem. This issue occurs when you water your lawn too often or for too long. 

Waterlogging disrupts the supply of oxygen to the roots of the grass. That way, the grass cannot grow properly. Along with the waterlogging can cause problems with the drainage system of your lawn.

3. Spreading of Bacterial and Fungal Diseases

Watering at night causes bacterial and fungal growth. When your grass is wet for a long time, it becomes the ideal condition for fungi to thrive.

The lawn stays wet all night long as there is no sun to complete the transpiration process. Rust, brown patches, and dollar spots are the perfect examples of grass diseases from staying wet.

4. Soil Erosion

If the water you spread into your lawn cannot dry the land, it can destroy the soil. The problem can happen if you water at night. 

As the water cannot dry quickly, it carries away soil. In this situation, you will notice bare patches and bald spots. 

5. Pests

Pests like slugs love to live in damp and dark places. Watering at night creates such an environment for them to thrive. 

These pests can damage your lawn by eating the roots and blades of the grass of your lawn. These pests can also spread diseases from one grass to another.

Best Time to Water Your Lawn

Should you water lawn at night or morning? Best time to water lawn is around 5 AM to 10 AM. This way, water will get to the root, and right after the rising of the sun, the grass can process its food with the help of sunlight. 

The oxygen transmission process will be perfect as the water is not clogging its way. The transpiration process will be more straightforward because the pores of the leaves will be open during daylight. 

The extra water will be dried up by the sun as the day advances. Threats of fungal and bacterial diseases won’t be there, and the health of your lawn grass will be on the top.

Let’s share some tips with you about the ideal time of watering your lawn.

4. How long should I water my grass: At least 15-20 minutes of watering is needed for your lawn. And the water should rise at least 3.5-4 inches. 

If watering from this time doesn’t provide 3.5-4 inches of water in your lawn, water for a few more minutes and note the timing. From the next time, you should follow the timing.
