Missing patches can be a big problem when you’re trying to grow your lawn up to standard and improve your home’s curb appeal. Even if they are small, the high contrast between the color of your soil and the grass will make such patches very easily visible from a long distance away. So, if you have guests over or your neighbors happen to drop by, they’ll quickly be able to see that something isn’t right with your lawn.
The best way to fix missing patches of grass is to start by by re-seeding. Although this approach takes longer and requires more effort, it is largely considered to be the best way. Start by raking the area, loosening the soil a bit, then ammending it and spreading the seeds. Then rake the seeds, begin watering the previously bare patch, and allow the grass to grow a little taller than the rest of your lawn before you start mowing.
Another approach (which is considerably quicker, but not as good) is to cover bare patches with a roll of grass sod. You can cut a piece that’s about 1-2 inches larger than the bare patch on all sides, and then place the sod patch in the right spot, while using a sharp tool to trace the area right around the patch. You can then rake the soil and make it nice and soft and after a week or two apply organic lawn care products for nutrition, so that the roots in your sod grass will quickly extend into it.
