We use a ride on core aerator by Exmark, which works much better than any walk behind core aerator you can rent as a do it yourself. This massive machine is guaranteed to pull plugs as you have never seen before. We begin our core aeration every year in May for warm season grass Bermuda Zoysia, when the grass is actively growing. This is the absolute best time to have your warm season lawn core aerated for a number of reasons. One, the grass can heal and fill in any open areas after soil plugs are removed. Two, typically lawns are a little softer during this time of year, which allows us to pull much better plugs. Finally, crabgrass has already passed its germination period, so the holes from the core aeration will not be a bed for unwanted weeds. This additional service can be added to your lawn care program for an additional cost. Visit our contact page to submit your request.
