I recommend using a herbicide containing glyphosate. Glyphosate is the active ingredient in Roundup, which can be purchased at hardware stores. It comes in both concentrate and ready–to–use form and has no soil residual activity.
The tree is very sensitive to spray drift so care must be taken to avoid getting any on other plants. For best results apply this herbicide when the tree is actively growing and beginning to leaf out in early spring or mid–fall.
It can also be sprayed during summer if the leaves are not present, but control will likely be suboptimal. At least one application may be needed for complete control, and more applications are needed for larger trees. I do not recommend native alternatives to glyphosate because they tend to be less effective and cause far higher environmental impacts than glyphosate.
What if you already have a large Acacia tree?
If you have an established tree that is causing problems, it can often be managed by using herbicide. The best time to spray is in early spring or mid–fall when the leaves are off the trees. Watch out for spray drift and avoid getting any herbicide on neighboring plants.

Pinus is a Gymnosperm and has naked seeds. Gymnosperms are nothing but trees with naked seeds. Other plants that have naked seeds include Ginkgo, Conifer, and Cycad. In these plants, the seeds or ovules are not enclosed by an ovary. Instead, they stay visible with leaf-like structures called MegaspoRead more
