How do you get rid of Florida Bettany weeds?

Digging up, supporting competitors, and using sprays are ways to eliminate Florida Bettany weeds.

Specifically, the plant in question (Stachys floridana) can be challenging to control and eliminate. Two particularly environmentally-friendly options involve digging up the roots and encouraging nutrient-seeking rivals. Removing roots is challenging since Florida Bettany has stubborn tubers which must be taken out in their entirety. Supporting competitors is easier since it involves maintaining dense, lush lawns. A bit less environmentally-friendly since it involves chemicals will be recourse to pre-emergent (especially with the active ingredient atrazine) and post-emergent (especially with the active ingredient glyphosate) herbicides.

A general rule to remember is that an assiduous, methodical program of controlled burning, regular spraying, and severe pruning generally will do in any weed in 1 - 3 years.
