What Will Happen if You Miss a Day of Watering Your Grass Seed?

💥 If you miss a day of watering your grass seed, there is no great harm done. Missing a day of watering the grass seed should be fine, but two or more days of missing it and having no rainfall might kill your seeds, which will require you to start over.


Planting grass seed, just like any other plant, requires specific care requirements, and watering is on top of the list, especially during the germination process. Your newly planted grass seed needs watering, with the frequency depending on the weather; water daily if the weather is over 80 degrees Fahrenheit, every other day if the temperature is cooler, and skip watering if it is raining. .

If the grass seed grow, you may reduce watering frequency but you still need to water deeply. While your grass seed is not going to die immediately if you missed a day of watering, it does not mean that regular watering is not a crucial thing. .

As you plant your grass seed, we bet you already know that it only germinates and will only continue its development process in ideal conditions, which does not include being exposed to dry conditions. 

The time after planting new grass seed is when the critical growth period starts as they are establishing themselves, so you should not skip a day of watering them. The seeds that already sprouted may have stored some water, but keep in mind that the moisture they have is not enough to last them days, especially when the temperature rises and the soil dries out quickly.

What To Do if You Missed a Day ?

In general, forgetting a day of watering will not cause your grass seed to die, so relax now, your grass seed will still thrive even if the day passed and you forgot to give them water.

What you have to do is wait for the next morning and water like you normally would — once early in the morning and once late in the afternoon.

If you feel the need for watering grass seed at night to make up for the whole day that you missed, do not do it or you will face undesirable results. If grass seeds are given water at night time, they will possibly develop fungus and molds because of the absence of sunlight.

Sunlight prevents the growth of microbes and spores in grass seeds, so the lack of sunlight will allow illness to spread rapidly among the seeds or prevent these young seedlings from sprouting.

– Grass Seed Drying Period

Grass seeds dry out in 12 to 24 hours without water. However, the length of time that it will take also depends on the day’s weather. If the weather is sunny and the temperature reaches about 75 degrees Fahrenheit, expect your grass seed to dry out in just 12 hours.

Skipping a Day of Watering Grass Seed

How soaked the young seedlings may already be will also determine how quickly the grass seed will become dry, especially if they experienced prior rain. In just two days of missed watering, grass seeds will dry out and will not continue with the germination process because they cannot live without water beyond that duration.

What Should You Do To Keep Your Grass Seed Watered?

To keep your grass seed watered, you should set an alarm, put an automatic timer on the garden hose or sprinklers, set up an irrigation system, hire someone to do it for you, or plant during the wetter months of  the year.

Keeping the soil evenly moist in a consistent manner is very important to your grass seed’s growth development. Your grass seed should be watered daily, deeply, and infrequently depending on your season, location, and temperature requirements.

After planting, make sure to water grass seed twice a day, and then reduce it to once daily after a week. However, if you cannot keep doing it consistently, we are here for you, and we have prepared options for you to be able to not miss a day without watering your grass seed.

– Set Up an Irrigation System or Timed Sprinkler

An irrigation system is a system in which water is distributed to the entire lawn uniformly. This is surely an effective way to not miss a day of watering grass seed and make your lawn grass lush in no time.

An irrigation system is a more expensive but less time-consuming option than an outdoor spigot. Make sure that you install the irrigation system first before you start to spread the grass seed over the entire lawn. However, using a sprinkler to water your lawn is the most common method!
