Over the next two days the putting greens will be "vented". The process of venting involves placing a 3/8 of an inch hole on 1.5 centers roughly about 3 inches in depth. Venting improves the Turfgrass health by:
Allowing increased oxygen exchange within the root zone
Increased water infiltration into the subsoil
Added root growth while temperatures are moderate
Venting is completed roughly every 25 days, it generally takes about 15 hours to topdress, punch holes and roll the surfaces. It generally takes a few days for the holes to completely close.
