Huisache is often considered the scourge of the coastal plains. These thorny trees can overpopulate a pasture, hay meadow or what was once a pristine prairie in less than a generation, turning an area into a thicket of un-accessible pasture.
The standing joke about controlling Huisache has always been, “the best way to get rid of Huisache is to move,” because there didn't seem to be any foliar applied herbicide that gave more than about 60 percent control. The reason for the difficulty in controlling Huisache is the “bud zone” that sits about 6-8 inches below the soil surface on the trees. Cutting the tops of the plants off initiates a reaction from that area to send up as many stems with leaves as it possibly can as a survival mechanism.
Many pastures that have been shredded year after year have now created low growing Huisache shrubs that can completely cover an area, limiting grass growth and making it a painful proposition for man and animal to use that particular piece of ground.
A Huisache and Native Prairie Restoration Field Day will be held on Friday, Sept. 13, at the B. R. and Charlene Koehler Farm, located at 4596 Kurtz Road in Sealy. The field day is scheduled to begin at 8 a.m. with registration followed by the program and field demonstrations beginning at 8:30 a.m. and concluding at 10:30 a.m.
Participants will be able to see the effects of mechanical and chemical Huisache control and a successful native prairie restoration site. Dr. Megan Clayton will be on hand to discuss the preliminary results of applied research on foliar applied herbicides for the control of Huisache. There will also be discussion on the best methods for restoring native prairie and management of them once they are established.
