Chamberbitter (Mimosa Weed) Control: Pre-Emergence Timing Is Key

Chamberbitter (mimosa weed) resembles tiny mimosa seedlings but has yellow seeds under leaf midveins. Post-emergence: repeated 2,4-D applications (Weed-B-Gon, etc.) when young. Pre-emergence: atrazine (Purge) on centipedegrass in early May and mid-June; isoxaben (Gallery, Portrait) on all turfgrasses same schedule. Hand-pulling works if you discard plants immediately—don't compost.
