Grape mulch for Apple tree
Can I use grape casings (I think that's what they are called) for mulch on my apple tree? We have two bags of them left by the previous tenant. I live in wine country where these are plentiful. They seem barky and small so I'm not sure if they're actually the discardings of wine production or shredded up vines (I'm thinking the latter).
I was able to prune most of the tree this weekend. Not sure if I should get the branches that go straight up from the main branches, but I also assume I shouldn't prune too much at a time. A website with really easy instructions would be great, and I'm sure if I spent more time on this site I'll find it. I mostly just need to know about the grape whatever it is as mulch.
