Sugar Maple: How to stop post pruning “bleeding”

After removing several branches from a sugar maple in early December, the affected areas won’t stop “bleeding”. Applying Wilson Pruning spray has no effect. Any suggestions?

Robert, the answer to this question might depend on what part of the country you are in. Can you tell us what area/zone you live in?

Robert,
I am an arborist working in Atlanta (www.arbormedics.com, http://www.atlantatreeinspection.com). Most of the “bleeding” that you are witnessing is caused by root pressure. It is simply water being absorbed by the roots and pumped into the tree’s vascular system due to osmosis. There is no major cause for concern. It will eventually stop as the tree compartmentalizes the wounds, with no lingering ill effects for the tree.
I would not try to seal the wounds with any pruning sprays or other tar-like products. They can have adverse affects beyond any benefits promoted on the label.
Enjoy your tree!
Chris
