A few months ago, we had to take out a white pine that was pulling up its roots. I thought my tree woes were over, and then my husband was playing with our dog and found that a large silver maple in our yard had a large crack in it. The tree is huge, and has three large limbs that split out from the trunk about 12 feet up. I'd hate to have to remove the tree, which provides a substantial amount of shade and is a regular home to birds' nests, and am interested in having it cabled in some way to stabilize the branches. Is that likely to work? Our neighborhood is loaded with multi-trunk silver maples and Sycamores--obviously planted by a developer who was not very interested in the long term health of the trees.
