I'm hoping to get suggestions about how to deal with two trees on our
1. The first is a large tuliptree (Liriodendron) which has a
circumference of about 80 inches. I suspect that it was struck by
lightning at some point, as it has a large scar running down one side
of the trunk. When we first moved into the house, I cut down a dead
dogwood next to this tuliptree that had a shattered crown and charred
streak running down the center. Perhaps lighning jumped from the
tuliptree to the dogwood? Anyway, there is a mouse-hole sized hole at
the base of the trunk, and I can insert a bamboo stake about 15 inches
back into the trunk. Wiggling the stake around suggests that the
hollow is quite wide.
The tree appears quite vigorous; it blooms in the spring and seems to
have a healthy crown of branches. But if it collapses, it could hit
the house, or in the other direction, it could completely cross our
street. I have an arborist coming to look at it later in the week, but
I thought I'd ask here first. Is this a good candidate for removal? I
hate to remove such a large, beautiful tree (and I shudder to think
what it would cost), but I don't want it to drop on my living room.
2. The second is a sweetgum (Liquidambar), about the same size as the
tuliptree. It's a beautiful big tree that shades our house in summer.
It used to have a smaller secondary trunk (~8 inches diameter) that a
previous owner cut, presumably because it was leaning over the house.
The smaller trunk was cut on an angle to shed rain, but even so, it is
starting to rot out. Is there anything I can do to prevent the rot
spreading to the main trunk, or is that inevitable?
