Dear Helene,

The type of shoots you describe along the trunk are common on Pyrus
calleryana and Pyrus betulaefolia - particularly younger trees, so I would
imagine P. usserensis to be no different. Just rub or cut them off. I have
also occasionally had the buds fall out when the pear graft seems successful
but the scion wood rather old. I think you need to start over with these
grafts.

Regards, Ethan (Zone 9)

trunks (average 2" in diameter) are kind of scaly, but I think they are
supposed to look like this. The top branches are smooth and greyish, so are
the new shoots along the trunk (some of which are close to a foot in length).

There are not too many pear trees growing around here to inspect and I read
many times in books that pyrus don't produce spontaneous buds.

have at least three pyrus ussuriensis that sent a few odd shoots out of the
side. And I should add that I also noticed a Luscious grafted onto unknown
rootstock that has a shoot in the Luscious part of the trunk.

at least the wood part, but instead of a bud, in the middle of the wood
piece, there is a hollow part where the bud should have been. In other word,
I have live Comice wood integrated into the tree, with no buds on it. I have
a few of these. After the second winter, the wood still looks good. It's
alive and calloused and is part of the tree. I was planning to cut those
branches with the chips on them, in a few weeks, and graft some new material
of a different variety to replace the unsuccessful budding. Is it worth
waiting to give those chips a second chance ....?
