Hydroseeding is definitely the easiest way to add grass to your property. However, while lawn spraying is easier than laying sod, there are still some mistakes you can make that will cause your lawn to not turn out how you would like. Then, you may be required to reseed your lawn to correct it.
Choosing the Wrong Seeds
Choose a seed that is well-suited for your climate. No matter how much effort you put into improving the conditions of your grass, if you choose grass that is simply not meant to grow in your area, you will have a lot of dead patches in your yard. Even if your seeds are supposed to grow in your region, they will not grow well if you purchase bargain seed. The less expensive seeds will be less likely to germinate, which will leave many more dead patches in your yard. Also, bargain seeds are more likely to have weed seeds mixed in. If you choose a seed that is very reliant on fertilizer, you may not be able to get the seeds to germinate because you will discover that some of the seeds are not easy to access.
Not Preparing the Seedbed
If your seedbed is not prepped before you spray it, your grass will not receive the nutrients necessary to grow properly. Test the soil with a digital pH meter by inserting it into the soil, waiting a minute and checking the reading on the digital display. It should ideally have a pH between 6.8 and 7.2. For sandy soil, add 60 pounds of limestone per 1,000 square feet to raise the pH or add 45 pounds of sulfur per 1,000 square feet to lower it. Clay soil needs 230 pounds of limestone to raise the pH and 70 pounds of sulfur.
Apply five pounds of fertilizer for every 500 square feet. If you are using liquid fertilizer, spray it as evenly as possible throughout your yard. Granule fertilizer is best applied using a hand-rotary spreader.
Walking On the Application Site
Do not walk on the areas that you seeded. This can create indentations and bare spots that will be highly visible. Once the grass has grown to the extent where it needs its first cutting, you can begin walking on the lawn. Try to walk your dog in an area that does not have hydroseeds because pet urine can leave dead patches.
