Stopping Live Oak Root Sprouts in Monkey Grass Beds

Managing Suckers from a Live Oak in a Planted Bed

Adding soil and irrigation over oak roots stimulates sucker growth. These clonal shoots will keep coming.

Control Methods

• Woody weed killer: Products for poison ivy/brambles (e.g., Roundup Poison Ivy Plus) kill suckers but risk harming the tree if absorbed.
• Physical removal: Dig and cut the root connecting sucker to main trunk. Temporary; repeats every few years. Difficult with monkey grass in place.
• Heat gun: Sear small suckers at ground level.
• Best long-term fix: Remove monkey grass, rebuild bed as a raised bed with weed barrier fabric over soil. Suckers are blocked and light-starved.

Note on Acorns

Some "suckers" may be seedlings from acorns—pull these by hand when small.

Redesigning the bed with a barrier is the only permanent solution.
