We need to trim our tree, and is best to do when it's dormant in the winterSo we need to mark the bad branches now, while we can see and compare based on production of fruit and leaves.I'm trying to avoid having to buy the special plastic ribbons my grandpa used to use in his Walnut orchard (this is just for an Apple tree in our backyard)Would yarn withstand the Seattle rain fora few months, or would it wear away?
