When Should You Water Your Grass Seeds?

Right after you’ve planted the grass seeds, it’s recommended to water your lawn every day, but only with a small amount of water. You can start with two to three times a day, watering it for about ten minutes. Be sure to keep in mind that the top two inches of the soil are supposed to be moist at all times.

Once your grass seeds sprout, water them once a day for a longer period than you were initially watering them.

The grass that is one inch tall requires less watering than the seeds because, at this stage, we’re waiting for the grass to form deeper roots – a process that doesn’t require an excessive amount of hydration.


Additionally: You should consider the type of lawn you have, namely, whether you’re trying to overseed an existing lawn or planting grass for a new lawn.


Type of Lawn

If you’re overseeding an existing lawn, you should water the grass seeds twice a day for fifteen to twenty minutes.

It’s important to water heavily to wash grass seeds down the cuts in the soil.

On the other hand, if you’re watering a new lawn where you just sowed your grass seeds, you should be careful not to overwater them.

Ideally, you should water them for about two to six minutes. The process should be repeated two to three times each day.

Also, it’s worth mentioning how critical the amount of water is when watering your newly grown grass. Both too much water and too little water can be damaging for your grass seeds.

Overwatering can drown the seeds or wash them away. On the other hand, not enough water, of course, may kill the sprout.

So, you should try to keep the ground moist at all times, watering your lawn on a fixed schedule, and in that way, making sure that the grass seeds are adequately hydrated.

It’s best to set up a short-term routine during this time.

Factors Affecting Watering Grass Seeds

Watering grass seeds is pretty much the same for each newly planted grass, regardless of the grass type, so there’s no need to worry about this aspect.

However, you should keep in mind certain factors that would affect watering your grass, such as the time of the day and weather conditions.

So, let’s have a look at them.

Time of the Day

As for the time of the day, it’s best to water your lawn early in the morning and in the afternoon, a few hours before the sunset.

In this way, you can avoid wind that could potentially blow the water away. However, if it’s summer or you live in a region where the temperatures get extremely high, the best way to prevent evaporation is by avoiding watering at noon.

On top of that, when you water grass seeds in the afternoon, you allow enough time to pass before the sunset so that the soil isn’t moist throughout the night, which could result in fungal infections and mold.


Have You Noticed: If you see moss or similar growths in the gaps between your grass, it’s a sign that the soil is too moist. If this happens, you can reduce the watering frequency and the amount of water you use.


Weather Conditions

Another important factor is the weather.

Weather determines the need to water your grass seeds or not.

For example, if it’s rainy, of course, there is no need to water your grass seeds as much as you need to during sunny days when the soil is dry.

Furthermore, if it’s windy, the water that you use for watering the soil may not soak in properly.

Extra Tips

When watering grass seeds, you have to know some tips that would help you water your newly grown grass effectively.

How to Water?

When hand watering, you want to try to imitate the rainfall, with the water flowing from above the seeds, not at an angle, so you can avoid washing the seeds away.

Type of Sprinkler

The type of sprinkler depends on the size of your lawn, the shape of the area, soil type, water usage, and your budget.

So, if you have a large lawn, you may want to consider investing in a rotating sprinkler. For a medium-sized lawn, you can opt for an oscillating sprinkler.


Your Choice: Also, don’t hesitate to spend some extra cash on a sprinkler, as it will ensure an even distribution of water. But, don’t worry; it’ll pay off in the long run, and it’s definitely easier than hand watering your grass seeds.


Cover It with Mulch

Scatter a thin layer of mulch on top of your newly planted grass seeds.

This will help keep the moisture until the next watering session.

However, there’s an exception here: When overseeding an old lawn, covering your seeds with mulch isn’t necessary since the old grass already holds the moisture.

Last Words

That being said, we hope that you have a better idea of how to properly water your grass seeds to keep your newly grown grass nice and lush.

Also, keep in mind that overwatering the soil isn’t a good idea, even if you feel like it’s a good one.

So, make sure to know all the information about weather conditions, the timing of the day, and the type of lawn, and you’ll have hassle-free, properly watered grass seeds.
