Back when it had leaves, we took a sample to Bordine's. The tree-guy there identified it as a Cherry. Never saw any fruit. It might have flowered once, the first year we were here.
Even then, it was in rough shape. I brought-down the lowest horizontal branch, which was obviously rotten, the first summer. The branch was dropping bark and branchlets into the yard. We hoped that removing the obviously-diseased branch and applying a fungicide would save the tree. It did not. The tree has been succumbing since, each year losing a higher branch. This last summer it had only token leaves on the highest branches. A month or two ago we noticed ear-type fungus growing on the trunk. Clearly dead.
Didn't threaten the house, really (might have brushed the south-west corner, but that's all). Did threaten the fence. With the multiple trunks, I needed help to fell it. Cutting through the south-pointing horizontal branch, outside the fence, was the obvious initial cut. But I wanted come-along ropes to ensure the tree dropped where I wanted it to drop. Adam and Liz were here and happy to help (Thank you!). Nic stayed with Goobs, and away from chainsaws, while we felled the tree.
Now I have to decide what to do with the wood. The easiest thing is to cut it into firewood. But I have two 5-foot racks full of firewood already, and the idea of burning Cherry is repugnant. You make furniture out of that stuff, you don't burn it. I guess I try to rough-cut it with a chainsaw into planks. Maybe split some into something resembling turning blanks for Dad.
