You may be looking at your lawn to deliver a lush green blanket in your garden, yet you begin to see some spots that appear to be thinning, and the grass just isn’t pushing up as you expect.
It can take lots of hard work for the ultimate lawn care, and you can face issues when a mix of watering, fertilizing, and mowing doesn’t do anything to help.
Once your lawn shows signs of thinning or bare spots are emerging, then it is apparent that you need to reseed your lawn in those areas.
In this guide, you can learn how reseeding lawn bare spots can help you get back your precious green lawn rather than looking at patches of dead grass.
Can You Just Sprinkle Grass Seed on Lawn?
If you sow grass seed over your existing lawn, it is what you hear as overseeding. You can do it, yet if you take the time to prepare your lawn first, you are setting yourself up for success rather than failure.
The bare spots are there for a reason, so new seed may not do anything on its own. Here you can see a few reasons that cause grass too thin in certain areas.
- Hard Soil: If the soil is too compact, it can prevent grass growth. Roots struggle to get air, water, and nutrients.
- Insufficient watering or mowing: If you have neglected using the top-rated lawn mowers, or pulling out your best garden hose, then this can influence the growth of grass.
- Lack of fertilizer: You may not have fed your lawn the right amount of fertilizer.
- Disease: Disease and insects can affect grass growth. Powdery mildew or Japanese beetles can have an impact.
- Shade: Too much shade can affect the overall health of your grass. Make sure you don’t have areas that are in constant shade all through the day.
How Do You Fix Patchy Grass?
Once you find out what is causing the patchy grass, you can see here how to reseed lawn if you need new grass in patches.
One of the first things you need to be sure of before overseeding lawns is that the soil temperature is around 52 degrees Fahrenheit. Besides this, you need good seed-to-soil contact so that the seed can germinate quickly.
- Take a sharp shovel or spade and cut around the dead turf patch.
- Lift off the dead turf
- As you are removing the top couple of layers of thatch and grass, fill in the area with good topsoil and rake it level with the remainder of your lawn
- Sow a thin layer of seeds across the area and take your rake to spread your seeds thinly across the areas you have dug out
- Cover the area with a thin layer of straw to stop birds eating your seeds
- Water the areas in the morning and early evening until your seeds show signs of germinating.
- Once your seed is germinating, water your lawn daily until it is ready for a light application of fertilizer before the heat of the summer arrives.
How Do You Reseed a Dead Lawn?
If your lawn is suffering in more than a few areas, you may need to deal with it as whole rather than separate patches. Drought conditions can cause this rather than different issues that cause a patchy lawn.
When dealing with a dead lawn, you can follow the best way to reseed a lawn guidelines. Doing this will help with overseeding your lawn after you take the necessary preparation.
You tend to find when lawn overseeding, grass seed germinates quicker in September and October when it is slightly cooler, and there are moist conditions. However, the temperature still needs to be high enough as not to retard growth.
- Clear dead grass, matted grass, or weeds to grass, as the seeds will germinate more successfully with good contact to the soil.
- Loosen the surface of your soil up to about 2-inches before overseeding the lawn. If you have compact soil, you can work in some organic matter or a thin layer of compost.
- Scatter your seeds across the surface. You do need to be sure you are using cool-season grasses or warm-season grasses that are suited to your region and the USDA hardiness tables.
- Scratch the seed into the surface to at least 1/4 of an inch. Lightly tamp the surface to make sure you have good contact.
- Add some fertilizer, which is formulated for new grass growth.
- Add a thin layer of mulch and water
- Make sure you keep the seedbeds moist while not over wet. If the weather is warm, it will require twice-daily watering.
Once your grass reaches a height of two inches, you can then reduce your watering to once every couple of days. You will then find the best time to mow lawn is once your grass reaches a height of around four inches.
Why is My Grass Seed Growing Patchy?
Even with all the above, you may still see your grass is growing patchy with your new seed. There are a few reasons for this and aside from a weedy lawn where the weeds can overpower your new grass growth. You may find your grass seeds are too old.
You can keep seeds for a while, yet their successful germination rates or viability are reduced. Be sure you are using new seeds when sowing new lawns.
You can also find that lack of preparation has an effect. Make sure to rake and keep soil contact as high as possible for your seeds.
One final thing that many gardeners overlook is the time of day when they fertilize their lawn. Rather than spreading fertilizer in the middle of the day, the best time of day to fertilize lawn is late afternoon or early evening.
In direct sun, it can burn your grass. In addition, more fertilizer doesn’t create more grass. Use the right sort of fertilizer spreader and apply sparingly.
