Puncturevine - Goathead - Texas Sandbur
Stepping on a Puncturevine bur is an experience that you will never forget! Each spiny bur or seed pod from the Puncturevine (Tribulus terrestris), also called the Texas sandbur, Goathead, or Jamaica feverplant (Tribulus cistoides and Kallstroemia spp.), contains 20 seeds equipped with long sharp spines capable of puncturing a tire or going through a boot. It takes only 3 weeks for this extremely hardy weed to sprout and make seeds. Seeds may lay dormant for up to 20 years until the right conditions come along for them to grow. Any established Puncturevine will continue to grow and spread until frost comes along unless you stop it.
It is easy to pull them from moist soil when young. They can be hoed or dug up as well. Once they flower and develop seed burs there are three methods of control:
- Eradication by herbicides.
- Spot use of flame - using great caution!
- Biological control with Puncturevine Weevils (Microlarinus lareynii and Microlarinus lypriformis).
