Q: I saw on your website that it could be a good idea to aerate highly compacted soil twice a year. Besides late April, when would be the best time to do the second aeration on zoysia?

A: Since the purpose of aerating a lawn is to increase its ability to grow, my feeling is that you could choose to aerate in late April and in early June. In both cases, doing the chore after rainfall has softened the soil a bit will yield deeper holes and better penetration of water and nutrients.
