I do expect the bermuda in the fairways that I sprayed as a part of our bermuda eradication program to wake up at a slower rate than the non-sprayed areas. The spray applied in early October right before dormancy injured it and the colder temperatures should have pushed this injury even further. There were seven acres of fairways sprayed with this material. I would expect these areas to delay in greening up. As they begin to emerge and there are larger areas of zoysia in some of these sections, I will probably spray them again delaying there growth further and allowing the zoysia to begin to fill back into the area. With The Invitational(Member/Guest) Tournament occurring the 2nd weekend of June, I will be working the spray application timing before and after this event to insure we have the best possible conditions for the event.
A word of warning to warm season turf owners. Do not get in a big hurry this season to do anything to your turf until it begins to green up and require mowing. Fertilization should always be delayed until you are sure all large patch on zoysia/bermuda is not actively growing. Usually mid to late May in St. Louis at the earliest. Dethatching a warm season lawn should be delayed until the lawn is actively growing and needs mowing. Performing these type of practices too early to your lawn could injure and allow for the emergence of summer weeds.
