Hi I have a 15yr old Bay Tree in a raised garden bed (with other herbs)..for the past few years it has been sending out shoots at ground level and I have been cutting them at or just below soil level...This enhances the growth however, and the number of "suckers" has become a problem as they branch from the previous cut area... HELP!! what do I do to reduce /stop this occuring? Or is it time to remove the tree ( which looks fabulous as I have topiaried it) and replace with a lemon tree???
