For lawns, removing cultivation cores is not typically necessary.

• A. False
• B. True
• C. Sometimes
• D. Rarely

Answer: (B)

The main idea here is how lawn core aeration works. When you aerate, you remove small soil plugs (cultivation cores) from the turf. In most cases, those cores are left on the surface to break down and reintegrate into the soil rather than removed.

Leaving the cores is beneficial because they are part of the soil you’re trying to improve. They create air spaces, improve drainage, and allow water, air, and roots to penetrate more easily. The plugs decompose fairly quickly and help add organic material back into the root zone, so removal isn’t usually needed. You can simply mow or water to help break them up and blend them back into the lawn.

There are niche situations where removal or additional steps might be chosen, such as very heavy thatch, overseeding where you want a smooth seedbed, or drainage issues with a lot of cores piling up. But for standard lawn aeration, not removing the cores is the typical practice.

So the statement is true.
