Have you ever tried to water a plant and it accidentally ended up swimming in the flowerpot?
Hey, I’m not judging you. It happens more frequently than you think.
When we start taking care of plants and gardens, everybody tells us to water them and not let them dry out, but what nobody says is how much water is actually necessary.
For lawns, it’s the same story. And there are even more factors to consider than just the amount of water. For example, certain types of grasses require more frequent watering than others to grow strong and healthy.
For those who want to know more about lawn watering requirements, in this guide, our lawn care professionals explain everything you need to know about watering lawns when deciding the best watering schedule for your grass.
Best Watering Schedule for Lawns
It doesn’t matter if you have an irrigation system or if you water on your own. To determine your lawn’s water requirements, it is important to understand:
- What type of grass do you have,
- Your local weather conditions,
- Soil type.
Watering Cool-Season Grass
Types of grasses belonging to the cool-season category usually need more water than other grasses, typically requiring around 1.5 inches of water or more per week.
Cool-season lawns include Kentucky bluegrass and Fine Fescue. During hot summers, these grasses go dormant, and when they are “sleeping”, they shouldn’t receive too much water. In winter, they almost don’t need water, unless it’s a dry winter.
Watering Warm-Season Grass
Warm-season grasses generally require around 1 inch of water.
Warm-season grasses grow perfectly under hot climates and are usually resistant to drought, but they need frequent watering. Some types of warm-season grasses that thrive in Texas include St. Augustine and Bermuda grass.
Types of Soil
Different soil types also influence your watering schedule.
There are four main categories of soils: sandy, clay, silt, and loam. These categories account for the soil particles and their ability to retain water.
For example, sandy soils retain less water, so water rapidly gets to the grass roots, and the soil dries quickly, as opposed to clay soils, which retain water longer.
Each soil type has its advantages and disadvantages. Clay soils usually benefit from longer watering sessions, but less frequently, while sandy soils require more frequent and shorter periods.
When Is The Best Time to Water a Lawn
The ideal moment to water your lawn is between 5 am and 9 am.
Let us explain: After 10 am, the sun rises and starts heating the ground. If you water when it’s too hot, the water evaporates quickly before the soil has time to absorb the liquid. So, it’s like nothing happened.
To avoid water evaporation, many homeowners opt to water at night, but this is also risky. Watering at night might give time for absorption, but an excess of water remains and does not evaporate.
Water that stands still and creates pools is a great place for fungus and bacteria to develop, leading to lawn diseases. Avoid watering your lawn when it’s too hot, or waiting until the last minute of the day to water your lawn, and it will be fine.
How Often and How Much You Should Water
Next, to make our watering schedule, we have to know how frequently we’re going to water.
Again, this depends on the needs of your grass type, but the general rule is that about 1 to 1.5 inches of water is sufficient.
Generally, watering 2 times a week in summer for approximately 30 minutes is enough for your lawn to receive this amount of water.
This frequency will change from season to season, too, as in winter you should water less frequently.
Oh, and consider rainfall when hydrating your lawn. If it rains, you can water less (thank you, Mother Nature).
Consequences of Incorrect Watering Schedules
Unfortunately, ignoring your lawn’s specific water requirements can lead to two instances: Over-watering or under-watering.
Over-watering refers to an excess of water. Too much water for your lawn results in:
- Weak grassroots.
- Thin blades.
- Thatch development.
- Fungus and diseases.
How to know how much water is too much water? Look for the presence of weeds and fungi, check if the earth is muddy, if the grass feels spongy, or if it looks yellow.
On the other hand, under-watering means that your lawn is not receiving sufficient water to grow healthy. Under-watered lawns can look:
- Brown, yellow, or grey.
- Covered with patches.
- Harsh, dried texture.
You can also notice a lack of water when you step on the grass, and the blades remain flat. If the grass goes back to normal, water levels are okay.
Both a lack of water and overwatering can seriously influence your grass texture. If your green and lush grass is experiencing changes, it might be time to review and adjust your watering schedule, as well as look for signs of pests or diseases.
Defining Your Lawn Watering Schedule
Wow, that was a lot of information. Who said watering the lawn was a piece of cake?
Many aspects come into play when you plan your lawn watering schedule, such as how much water your grass type needs, how the soil retains moisture, if the lawn receives natural water from precipitation, and even heat and cold.
Watering correctly is one of the most important aspects of having a beautiful and healthy lawn.
