I have a Amur Maple that is 4-5 years old and has been in my yard 2 years.
It has 12 shoots(trunks) and I want fewer, say 2 or 3.
How and when do I prune.
The tree is very healthy.
Amurs are really hardy and you can trim them anytime ..I know most say wait til late summer or fall to keep the sap in check but I have trimmed these year round with no problems ...and I mean i have severely trimed them!!!! they grow like weed really fast and outgrow just about any place you put them... I set a big brush fire too close to one and lost a bunch of brancheds last spring .... it came back and by fall was three times it's "burnt" size I love 'em BTW but if left single trunk they can get 20 ft tall in probably 5 years around here ...SO have "at it" is my opinion I really don't think you could harm it if you tried!!! BTW don't do this with JM's!!!!! David
