|My back yard is full of weeds. Every year I put down weed killer, I have planted seeds, grass and nothing helps. My back yard is dry and sandy. I have even put down soil and it seems to wash away in the sand. What should I do to have some grass.|
|There are a couple of ways to renovate your lawn. You can rototill it up and start all over, or you can rent a core aerator and aerate your lawn, then spread some sand or compost over the area and re-sod.
If you decide to redo the entire lawn, start by rototilling the area to break up the soil. Remove any debris (stones, sticks, weeds, etc.) and then spread 4-5 inches of organic matter over the area and rototill it in, then rake the area smooth. Sod produces an almost instant lawn because the grass is mature with a healthy root system. After laying the sod and watering it down well, it only takes a week or two to become firmly established.
The second option is to aerate your existing lawn. A core aerator will remove one inch by three inch plugs from the lawn. Leave the plugs on the lawn and they will dissolve in rain or water from the sprinklers. After aerating spread a thin layer of sand or compost over the area and water it in well. The sand or compost plus the soil from the plugs will work their way down into the holes left by the plugs. You can then resod your entire lawn.
Either approach should improve the soil beneath the lawn and help your lawn grow lush and thick, which will help crowd out any future weeds. Once the sod is in, be sure to water, feed and mow on a regular schedule. Best wishes with your lawn.
