How long does it take to boil it down, and where do you do it? R

Again you are talking about the recently-dead layers (xylem) immediately under the vascular cambium. Under that layer is the secondary xylem, which no longer conducts water and is used to store waste products (in some cases - resins). The secondary xylem is also known as heartwood, and this is what is used to produce modern dimensional lumber. Both the Xylem and heartwood (secondary xylem) are composed of dead cells. They are structurally intact, but they no longer respire (ie - they are not biochemically active). When a limb of sufficient size is cut near the trunk, you will be exposing this dead heartwood region, which is incapable of protecting itself against weather, sun, fungal and insect dammage. Only new cambium growth over the exposed area will eventually provide this protection. > It will do this whether or not it is still in tree form or > built into a deck or whatever. Not really. Heartwood is not a good conductor of water. In fact, it is necessary that the heartwood not contain significant amounts of water, since that would dammage it during freeze-thaw (expansion-contraction) cycles in the winter. > Any coating put on a tree that is intended to protect it from water > will interfere with the tree's eons-long evolution of its healing > process. Heartwood is not normally exposed, so the application of a coating to it will shield it against sun, rain, humidity, fungal and insect attack. Normally the cambium and bark performs this function. > It is important how, when and where to prune limbs. Improper > pruning will not allow the tree to heal. Yes, there is a correct cut-line to use for the most optimal removal of a limb from the trunk. But we digress.

Um - I didn't think that silver maples gave good syrup. That's why sugar maples are called "sugar maples".

That's a sugar maple. Leaves shaped like the one on the Canadian flag, with dark grey-brown bark and well-behaved roots (they stay underground). Silver maples have white bark, leaves are pointed ovals, dark green on top and silver-white on the bottom, with roots that break the surface every 2-3 feet. Sugar maples are good trees; silver maples are not.

No. no. no, and definitely don't. > >Silver maples have white bark, leaves are pointed ovals, dark green on >top and silver-white on the bottom, with roots that break the surface >every 2-3 feet. Also known as swamp, river, white, soft, or water maple. The Latin taxonomy is Acer saccharinum. An argument has been made that Linnaeus meant for the Silver Maple to be a sugar maple-- it was a century later that someone named the Eastern US 'sugar' maple. ("The Sugar Maples" by Benjamin Franklin Bush, American Midland Naturalist, Vol. 12, No. 11 (Sep., 1931), pp. 499-503) See my other post for my own experience with both species on my property. > >Sugar maples are good trees; silver maples are not.
