Giving Turfgrass Extra Space

We've discussed aerating before, but it is the time of year for questions about aerating to start popping up.

Why Aerate?
In short, aerating opens up soil for better air and nutrient movement.

What is an Aeration?
During an aeration, a machine pulls cores from the lawn and deposits them on top of the soil. (These cores break down readily, so there is no reason to rake.)

Should you Aerate?
Lawns with heavy clay soil are especially susceptible to compaction and should be aerated on a regular schedule. Likewise, if you cut a square in the lawn at least 6 inches deep, and the roots of your grass only extend 1-2 inches, it is time to aerate.

When should you Aerate?
Bluegrass and Fescue lawns are aerated in the early spring or in the fall. Bermuda and Zoysia lawns are aerated from late May to July. (Basically, the best time to aerate is when the grass is actively growing.)
