I have been worried about this silver maple for several years now. If it splits, one piece will crush my house and another will crush his. It's about 60 years old, and is not looking real healthy by the look of the foliage. It's 3-4' in diameter at the base. I mentioned this to my neighbor a month or so ago. Today, a he had a tree guy out, and now has decided to take the tree down. When I mentioned that I would like the wood, the tree guy was happy about it, and after a little more talking, agreed to block it in 18" sections! And he'll take the large main stem, which I really can't handle. That's how he usually gets rid of his wood. It is silver maple, but it's about as close at it could be. That's my driveway in the picture. This will set me up for wood for quite a few years! The limb on the left is about 2.5' in diameter (and would fall towards my house if it split), and the other ones are around 2'. The tree has not lost any leaves yet this fall, and has never been trimmed. The crown is just that thin... It's about at the end of it's natural life for a silver maple in the city.
