Your grass constantly needs water to prevent it from dying, but too much water can be just as harmful. When you water too much, your grass is more susceptible to pests and diseases. It can also lead to thatch build-up, which blocks nutrients from getting to the roots of your grass.
Watering too little might mean that it won’t be able to reach its full potential height. To keep your grass healthy, it’s essential to water it the right amount and at the right time of day.
What Temperature is Too Hot to Water Grass?
The ideal temperature range for watering grass is between 60 and 70 degrees Fahrenheit. If it’s too hot outside, the water will evaporate before it has a chance to reach the roots of your grass.
If it’s too cold, the roots won’t be able to absorb the water. When it reaches 95 degrees Fahrenheit, it’s simply too hot to water your grass.
Why does it matter? During the hot summer months, the water may quickly evaporate before it even reaches its roots.
If you water when it’s too hot, the water will just sit on top of the grass (which could cause fungal growth) and won’t be able to penetrate the soil to reach its roots.
Watering Your Grass Early in the Morning
If you live in areas with high heat and humidity, it’s best to water your grass early in the morning before the heat of the day sets in. This will give the water a chance to soak into the ground and reach the roots before it evaporates.
That means that more of the water will actually be absorbed by the roots of the grass instead of evaporating into thin air.
Additionally, early morning watering helps to prevent fungal growth and disease, both of which can be problems during hot summer days.
Benefits of Early Morning Watering
Watering your grass early in the morning has a few benefits:
- Water will be able to penetrate the soil and reach the roots before it evaporates.
- It helps to prevent fungal growth and disease.
- The grass will have time to dry off before the heat of the day sets in.
- Grass will be less likely to become dormant during the hot summer months.
Watering Your Grass Early in the Evening
Alternatively, watering your grass early in the evening is also an option if afternoon temperatures have reached 95 degrees Fahrenheit. However, this option is not recommended if you live in an area with high humidity, as it can lead to common diseases such as brown patches.
If you do choose to water your grass in the evening, make sure that you do not water it too late.
Watering too close to nightfall can result in moisture staying on the leaves of your grass overnight, which can lead to fungal diseases. It’s best to water early enough so that the leaves have time to dry before nightfall.
