We have a Corkscrew Willow tree which currently has bark peeling off. We took the rest of the bark off to allow the tree to dry (to prevent moisture in the tree). I was wondering if we need to spray something on it? Also, we have been seeing some smaller dead branches on it lately, not sure if this is normal or not. Here some pictures of it, there's a bunch of random things we seen on it, including bugs, some sort of mushrooms (from the moisture?), and bumps:

    Given that willows are really tough and out grow a lot of problems you could hedge your bets and cut the tree down to the ground and wait. Chances are good it will sprout suckers at the base and in no time you will have the tree back as a shrub. – kevinsky May 26 '15 at 12:51

The fact the bark was peeling indicates something is going on underneath - the presence of fungus (mushrooms) is a good indicator that the tree is in very poor health, and will likely die. It may have suffered some kind of borer penetration, or a beetle infestation, or simply be sick at the roots, causing the bark to peel and fungus to start growing. When you removed the rest of the bark, you may have also removed some of the cambium and particularly the phloem layer - phloem is part of the tree's circulatory system, and its just beneath the bark. If you breached this area all round, the tree will die, but probably slowly.

Given it was sick initially, and now the bark's completely removed, it's probably safest to take it out, including removing the roots, just in case the problem started there.

UPDATED ANSWER:

In response to your comment, removing the bark wouldn't have helped at all (its a bit like you removing a layer of your skin), a tree needs its bark - but the fact is, the tree already had a problem, which was why the bark was loose, and it may have shed all the bark by itself over time anyway. You could try cutting it to the ground as suggested by someone else; if there isn't a problem at the root, it should/might grow again as a shrub, but do not cut past any graft present at the base - many Salix tortuousa are grafted onto a different rootstock, so if you cut too far, you'll just get the rootstock growing, not the corkscrew part.

  • Regarding the bark removal, were you referring to it being removed completely in a circular area on part of the tree, or the entire tree all around? (I thought that this was better to keep moisture out of the tree, did it only make the situation worse?) The bark seemed to already be loose on the tree. – AwesomeMarioFan May 27 '15 at 0:56
