lilac shrub rhizomes
My mature lilac bushes produce dozens of new lilac whips around the base of the shrubs. Cutting them off at ground level seems to do little more than to encourage more of them to form. Is there a product you would recommend to discourage their growth??

Lilacs naturally produce shoots (suckers) around the base of plants. Nothing can be done to stop lilacs from developing suckers. The only option is to cut off the suckers when they develop (if the suckers are undesirable).
