How Long Does It Take For Hydroseed To Grow? Let’s Talk About It!

Do you have a landscaping project as well? I have an area in my front lawn that I plan to beautify. My landscapers opted for hydroseed to make the scenery become green very quickly.

However, when I asked them how long does it take for hydroseed to grow, they said, “It depends on how would you like it to be, ma’am.” It may not be complicated, but I want to know how simple the process can be.

What Is Hydroseeding?

For a quick background, Hydroseeding is the process of mixing wood mulch, grass seed, fertilizer, bonding agent, and water in a container. All of these can blend together with a garden auger. When done, the tinted green mixture is ready for spraying on your new lawn.

Compared to sod, hydroseed is cheaper, needs a short time to grow and allows the roots of the grass to go a lot deeper underneath.

How Long Does It Take For Hydroseed To Grow?

Various factors affect the growth of a hydroseed. Nevertheless, the average length of time before you see fresh new grass sprouting is about nine (9) days. Within a month after, the grass would probably be 3 inches long and is due for cutting.

What Are The Factors To Consider When Planting Hydroseed?

The length of time waiting for the grass to grow are dependent on some factors. My landscapers made sense when they told me it all depends on how I would like it to be. Here are the factors that would explain why the growth span differs.

Soil Preparation

Whether you choose the traditional or Hydroseeding way of growing grass, its success greatly depends on how you prepare the soil. I understand that the first thing to do is eliminate all existing weeds and break down large lumps of soil by raking it. Remove any bumps that are bigger than your fist if it is hard to smash. 

Only then, it is right to put compost by plowing it about 6 inches deep down. I rake the soil to make it level and tap lightly with a water roller before it is ready for hydroseed application. Having a good quality of topsoil makes your grass grow fast. Therefore, working hard to prepare the soil is worth in having a healthy lawn.

Apparently, I am only familiar with sods, so this is my first time using hydroseed. A friend of mine suggested using Scotts Turf Builder Grass Seed since it worked well in her lawn than sods. Yet, you can check what works best for you.

Watering And The Weather

I need to keep the hydroseed mixture damp for the grass seeds to sprout. Hence, I water it four times daily for about three weeks. The amount of water is not accurate though. Because it depends on the water pressure, when it rains, and if I use the sprinkler or not.

Watch this video to have an idea on how it is to water hydroseed:

After a month, I start to lessen the water and give time for the roots to go deeper under the soil. Gradually ease back on watering until you only need to do so once a week. Remember, your lawn may seem to appear lush and green, but it would still run for a few months more before it would completely fill in the whole area.

I really recommend you have a sprinkler when watering. By doing it by hand took a lot of effort and time on my part. However, when your options are limited, do the planting in spring or fall like what I did to mine. The best time to plant grass seed is when the weather is colder, so it requires less water. 

Even so, planting in the summertime has its advantage too. The heat of the sun makes the seeds grow faster than in spring or fall if you are diligent in doing the watering. The ideal temperature for Hydroseeding is around 80 deg. F for the initial six weeks.

Hence, you watch out for extreme cold or heat since you need to give extra effort to take care of the seeds in certain conditions. Take note that hydroseed produces a 75% germination rate because the mixture sticks to the plain soil.

The Type Of Grass You Want

Sure, the soil preparation, watering, and the plowing contributes on how long hydroseed grow. However, it all boils down to what type of grass you want for your lawn. Different types of grasses take different period to germinate.

Some grasses germinate in just a week while others may take a month to grow. Keep this in mind when estimating the time you needed.

Upon learning the different aspects, you need to consider in determining the length of time you need to wait for your hydroseed to grow. Do you already have an idea on yours? From soil preparation, hydroseed application, plowing and watering. It will take seven (7) to ten (10) days before you see a glimpse of green grass in your lawn.


If your passion for plants is like mine, you will enjoy growing hydroseed. How long does it take for hydroseed to grow? Now I know that it depends on how dedicated I am on sticking to the right process of taking care of the seeds.

For mine, it took eight (8) days before I saw the green grass sprouting. I used Scotts Turf Builder Grass Seed for the first time, and it worked for me. I recommend this if you have not chosen any yet.

Besides, I invested in plenty of time and effort to make it happen. Try growing yours now, and know how the excitement feels while waiting for the seed to sprout. Are you interested in planting hydroseed? Drop a comment if you have more questions and let us talk about it!
