|Suckers growing from the base of a tree can be very annoying. One way to get the upper hand is to yank the suckers off rather than cutting them off. By pulling the suckers off you'll be removing the cells and tissues that encourage regrowth. Cutting the suckers to ground level has the opposite effect and will encourage further production. There is a product on the market called Sucker Stopper but I've never used it and can't vouch for it. But, it might be worth a try. Good luck with your olive tree!
