Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Please forgive us, but Mr. Smarty Plants has been overwhelmed by a flood of mail and must take a break for awhile to catch up. We hope to be accepting new questions again soon. Thank you!

Title: Eliminating prickly pear
Answered by: Damon Waitt


What is best practice for eliminating 100+ acres of dense prickly pear?


Texas is home to several species of prickly pear including Opuntia engelmannii var. lindheimeri (Texas pricklypear) and Opuntia engelmannii var. engelmannii (cactus apple). The Center for Grazinglands and Ranch Management at Texas A&M University System maintains an excellent discussion board dealing with Brush and Weed Management. There is an entire section devoted to Getting Rid of Prickly Pear. Within this website you will find recommendations ranging from individual plant treatments (IPT) to broadcast methods for large areas.
