How Long Can Hydroseed Go Without Water + [Some Care and Maintenance tips]

How Long Can Hydroseed Go Without Water?

The Hydroseed should always stay moist. That is to ensure that there’s proper germination. Also, for a newly hydro seeded lawn, you should make sure it is continuously wet for a minimum of 11 days.

So, How Do You Maintain your Hydro seeded lawn?

Too little amounts of water slow down the formation of the grass. The seedling may die if the germinating seed dries out. 

However, too much water causes washouts and puddling. Once germinated, excess water makes grass seedlings develop weak roots due to low oxygen supply to the sources. This leads to a slow establishment that result in a sparse lawn.

The seed, under optimum conditions, germinates in 5-10 days. However, it may take up to 14-15 days to grow if subjected to adverse conditions.

You have to ensure that people or pets keep off the lawn for around 2-3 months. Unless necessary, you should avoid stepping on the area after seeding.

Wrapping Up

If you have a lawn for hydroseeding, then you must be glad to get the above information.
