If it doesn’t penetrate, it’s time to aerate

Q: I sodded an area in my backyard last spring with fescue. I know I need to do some maintenance to it this fall. Do I just seed and fertilize, or do I need to aerate? It’s still green but starting to thin.

 

A: First decide if you truly have enough sunlight for fescue to prosper. If you don’t, consider rearranging your landscape to grow the grass in the sunniest spots.

Aeration might help if your soil is hard. Use a screwdriver to jab into the soil. If it doesn’t penetrate, then you need to aerate. Before you start, mow the lawn and water it thoroughly the day before. The aerator should use hollow tines to bring up plugs of dirt, three inches long. This is important: every square foot of the lawn needs ten holes. Anything less and you won’t see the benefits that you want.
