Prescribed burning is another option, which, if part of an overall range management plan for your ranch, can be an economical method of keeping huisache as well as other brush species in manageable numbers. In the Texas Coastal Bend burning a pasture every four years kills most of the one and two-year-old seedlings. However, most of the three-year-old seedlings and older plants will have the tops killed and will re-sprout the next year, according to experts with the Coastal Bend Prescribed Burn Association.
