Hand Pulling – Controlling Weeds
Q: When do I apply pre-emergent to my garden to control coffeeweed, bermuda, and Johnson grass?
A: You are facing a big problem. Pre-emergent chemicals are ineffective on coffeeweed seed. Bermudagrass and Johnsongrass are perennial plants and pre-emergent won’t hurt them at all. Hand pulling might be your best option. Or you can put some glyphosate (KillZall, Roundup, etc.) on a foam paintbrush and brush the chemical on the weeds as they appear.
