Removing an Olive Tree in California Without Herbicides

A California resident needed to kill an olive tree and its roots without using restricted herbicides.

Mechanical + Chemical Approach

1. Cut tree at ground level.
2. Treat stump immediately with "Sucker Stopper" (a California-legal sprout inhibitor). Check local garden centers.
3. Alternatively, grind stump below grade.
4. Persistently remove every sprout as it appears. Roots exhaust reserves and die—may take a full season.

Ideal (If Legal)

Painting the fresh cut with glyphosate (Roundup) is most effective, but verify local legality first.

Key Point

Consistency is critical: never let sprouts leaf out and photosynthesize.
