The longer candles are due to the deep pot.I’ve typically gone through the tree and would break the longest ones around this time. I intend to do the same Soon. Most branches have one long Bud and one shorter, so I will likely even them out. In past Years I was never seeing this many long candles throughout the tree. Most years it was just one short bud.
You are correct, the proper thing to do us shorten the long one to match the shorter one.
