Control of acacia tree sucker
Acacia tree cut down 18 months ago. Tree stub was treated; nevertheless, we are getting suckers shooting up all over the garden. How can I eradicate this problem? This is in the south of France.
Cut the suckers and paint the fresh cuts with concentrated Round-Up. The tree will suck the Round-Up into its system and kill it. It may take a few applications, but will eventually kill the roots.
