Those decks and stuff are *dead* wood. Presumably you cut the branch off on a live tree.

The squirrels don't find the bark so tasty with the paint. I prefer to apply lead directly to the squirrels. But I don't think squirrels do any damage to hollows in trees Jim

By rot, I mean the development of cracks, fissures, cavities and holes caused by the removal of wood caused by insect activity. I guess I used the wrong term. > All the wood eating critters I know about show up after the > wood is dead. When you cut a large limb off a tree, the inner wood that you expose *is* dead. The only living part of the trunk is the bark. > Those decks and stuff are *dead* wood. Presumably you cut the > branch off on a live tree.

If the cut is large enough, it will expose dead wood, and that wood is vulnerable to insect dammage and weather-related dammage (actual rot, fungus, etc). This dammage may set in before the tree has enough time to grow around and cover the exposed surface with new bark.

That's why >sugar maples are called "sugar maples". I have 2 sugar maples on the other side of my house. Probably about the same age as my silver- about 2feet in diameter. [the silver is 3-4] I tapped them a couple years. They gave less sap and it was not as sweet as the silver. I've talked to others with the same experience. Sugar maples are less prone to limb damage and don't have surface roots. But other than that I don't know why sugarbushes don't use them more. Jim [BTW- I've never tapped them, but others have extolled the virtues of white birch and Box Elder [aka Black Maple] sap.] |
