Getting your grass to grow can be a difficult task in the best of conditions. However, if your lawn has suffered from pests or disease, it might have some areas that are just dirt by now. Regardless of whether that’s what the problem is, or whether it was affected by cold winter temperatures, or it just hasn’t grown properly because of the soil, those areas will usually be obviously unsightly, and they have to be addressed as soon as possible.
One of the ways you can get your lawn growing again is by overseeding the affected areas. Some gardening professionals will point out, however, that the soil will also have to be tested and treated to make sure that the problem won’t repeat itself. So it’s a good idea to start by checking your soil’s pH, then aerating and applying a good soil treatment to prepare it for reseeding your lawn.
Another option that is typically faster but might not yield the same result is to buy sod and use it to complement the affected areas. That way you can get your lawn looking great right away. However, you might still have to inspect and treat the soil with special emphasis on checking for pests and unwanted insects, which could have the same effect on the sod that they had on the part of your lawn that was previously affected.
