You should water your grass about twice a week, providing roughly 1 to 1.5 inches of water per week in total. Each watering session should last about 30 minutes, which typically delivers about half an inch of water per session. This schedule encourages deep root growth, making your lawn more drought- resistant and healthy
. Key points for watering frequency and duration:
- Water about two to three times per week, each session lasting around 30 minutes to accumulate about 1 inch of water weekly
- Avoid watering too frequently for short periods, as this keeps roots shallow and weak
- Adjust watering based on rainfall; if it rains heavily, you may reduce or skip watering
- Newly seeded lawns may require daily watering until established
The best time to water is early morning (between 5 a.m. and 9 a.m.) to reduce evaporation and fungal risk. Evening watering is a second-best option but can increase disease risk if water sits on the grass overnight
. Soil type also affects watering needs:
- Sandy soil drains quickly and may require more frequent watering.
- Clay soil retains water longer, so water less often.
- Loamy soil is ideal for balanced water retention and drainage
In summary, aim for two 30-minute watering sessions per week in the early morning, adjusting for soil type, weather, and grass species to keep your lawn lush and healthy.
