Interesting answers...
When you drill a
hole to
tap your
tree for
maple syrup, it's generally 2” deep and less than 0.5” wide. To your mature 50-foot
maple tree, that's just a teeny, tiny
hole! Plus, the area you drill through
is filled with millions of small vessels that allow sap to flow.Feb 27, 2018
Does tapping maple trees damage the tree?
Tapping a
tree does create a wound, but it is a wound from which the
tree can readily recover and
does not endanger the health of the
tree. Commercial
syrup producers are able to
tap trees for decades without adversely affecting the health of the
tree. A vigorous
tree will heal, or grow over, a
tap hole in one year.
Does tapping a maple tree kill it?
Do NOT drill a
tree that is less than 10″ across. It's too young and
tapping it could
kill it.
Does tapping maple trees cause harm?
Maple trees are not harmed by the
tapping process unless a
tap is deeper than 2 1/2 inches into the
tree, where it is possible to hit the heart of the
tree.
