Lawn Care 101: The Best Times to Water Your Grass

At Archway Lawncare, we understand the importance of watering your lawn correctly to maintain its health and beauty. Watering at the right time and frequency can make a significant difference in the effectiveness of lawn care practices, such as fertilization and seeding. In this blog, we answer some of the most common questions about lawn watering, debunk myths, and provide expert advice to help you keep your lawn in top shape.

When is the Best Time to Water the Lawn in Hot Weather?

Watering your lawn during peak hot weather can be challenging, but timing is everything. The best time to water your lawn is early in the morning, preferably between 6 AM and 10 AM. This allows the water to soak into the soil before the heat of the day causes evaporation. Watering in the morning also gives the grass blades time to dry out before nightfall, reducing the risk of disease.

Is Watering Your Lawn at Night Bad?

The common myth that watering your lawn at night is harmful stems from the fact that prolonged moisture on grass blades can encourage disease. When the grass remains wet overnight, it creates an ideal environment for fungal growth. Although night watering is not as effective as morning watering, it is still better than not watering at all if morning watering is not possible. However, for optimal lawn health, stick to early morning watering whenever you can.

When Should You Start Watering Your Lawn?

In general, begin watering your lawn in early spring as soon as the soil starts to dry out from winter rains. Historically in Missouri, the opportune time will be between April and May. Consistent watering is crucial during this time to support new growth and prepare your lawn for the hotter months ahead.

When Should You Stop Watering Your Lawn?

Deciding when to stop watering your lawn depends on the cadence of rain through the summer and the type of grass you have. Typically, you should continue watering your lawn until the weather cools down in late fall. For cool-season grasses, it's important to water until the first frost to ensure the grass is well-hydrated going into winter dormancy. Warm-season grasses may require less frequent watering as they enter dormancy earlier.

How Long Should You Water Grass Seed?

When establishing new grass from seed, proper watering is critical for successful germination and growth. Water the newly seeded area lightly but frequently, keeping the top inch of soil consistently moist. This usually means watering two to three times a day for about 5 to 10 minutes each time. Once the grass seedlings emerge and establish roots, gradually reduce the frequency and increase the duration of watering sessions to encourage deeper root growth.

How Long Should You Water Your Lawn After Fertilization?

Watering your lawn after fertilization is essential to help the fertilizer penetrate the soil and reach the grass roots. For granular fertilizers, water the lawn immediately after application to activate the nutrients. This prevents the fertilizer from sitting on the grass blades and potentially causing burns. If using liquid fertilizers, follow the product instructions, as some may require a waiting period before watering.

How Long Should Sprinklers Run in Each Zone?

The duration for running sprinklers in each zone depends on several factors, including the type of sprinkler system, soil type, and grass needs. As a general rule, aim for about 1 inch of water per week, including rainfall. To determine how long to run your sprinklers, place a few empty cans around your lawn and measure how long it takes to collect 1 inch of water.  Adjust based on weather conditions and specific lawn needs.
