Dwarf Japanese Maple
My tree keeps sprouting new growth at the bottom of the tree. I prune it off , but it just keeps growing back. Is there something I can put on the trunk to keep it from sprouting after I cut it?
Pulling off a new sucker makes a clean break with the base of the trunk and it will not sprout from that same spot and require endless pruning. New suckers pull off relatively easily, but as they mature they become harder to pull off.
Once you have pruned a sucker, it will keep coming back, but there are products on the market that will prevent regrowth. Here is a link to one, but there are others if you look around at garden centers: http://www.countrymax.com/Bonide-Sucker-Punch-Sprout-Killer-8-Ounces/?gclid=CjwKEAjwlfO3BRDR4Pj_u-iO...
