Bare spots rarely form in your yard for no apparent reason. To fix a bare spot, you first have to know why it’s there. So, the first step to repair the spot is to take care of what caused it in the beginning.
If you have a dog, there’s a good chance that your pet may be contributing to the bare spot. Should you happen to already know that’s the reason, you can’t fix the bare spot permanently until you do something else with your dog. You have a similar problem if the bare
spot is the result of over activity from your family’s use of the yard. Unless you’re willing to change their play and recreational habits, you’re most likely stuck with a bare spot.
Moles can be another culprit. They push up the earth and expose the plant roots to air. This dries the roots and kills the grass. In order to repair the yard, you will have to either poison or trap the mole. There are several excellent products that will do one or the other.
You may have that spot from too much of something natural occurring. It might be too much shade from a tree. If the spot has tree litter covering it too often, you may have a soil problem from things that leach from the leaves and sticks decaying there. A low place that keeps standing water too long can do in the grass that tries to grow there.
Weeds can take over a patch of your lawn and when they die in the summer heat, a bare spot is left behind. You may just be unlucky enough to have poor soil in a small area that needs some attending. It may be where you burned leaves last fall and now the grass isn’t coming back because you changed the soil composition.
If the problem is from an animal or excessive use and you’ve eliminated the problem, take a rake and loosen the top inch or two of soil over the whole area. Sow a generous amount of the correct type of grass seed over the area. Cover with a thin layer of straw. This will keep birds from consuming your new seed.
