whats the best way to grow grass in heavy clay soil?

Answer 1

I agree with Kate about rototilling compost and some manure into your soil. You should also consider using some gypsum to help prevent compaction. Following is exactly what I did to improve my heavily compacted clay soil prior to seeding my lawn.

The compost should be applied at least 2 or 3 inches along with an inch of thoroughly composted steer/chicken manure over the top of your soil. And the gypsum should be applied at recommended amounts on the back of the bag. Once applied they can be rototilled into your soil prior to seeding/sodding.

The compost and manures contain beneficial bacteria and fungi that help;

1) Loosens the soil and allows oxygen and water to penetrate and get to the roots of the grass.

2) Utilize the available nutrients in the soil and make them more readily available to the plant.

3) Form a protective barrier around the roots to prevent diseases and root-invading nematodes from attacking.

4) Prevent an accumulation of thatch by consuming the cut grass.

I'd also recommend broadcasting (not rototilled in) a good starter fertilizer such as a 6-20-20 just prior to seeding/sodding.

Hope this information helps improves the condition of your soil and gets you a great looking lawn! GOOD LUCK!

Answer 2

Sounds like you just need aeration. Heavy clay soil yards ought to be aerated twice a year. You can rent a commercial grade aerator for a very reasonable price. You can also mix in top soil if you have the time and money as well as use lime as the other poster indicated.
