I just bought a small nectarine tree on a whim and planted it. I was reading on nectarine pruning and saw that most people seem to recommend pruning the tree upon planting but they also say you should prune before leaves emerge. I bought the tree with leaves already out so I'm wondering, should I just wait until next year when it's coming out of dormancy to prune or should I go ahead and lop the top off now? My gut reaction is to let the tree get established this year then do the first major prune next year but I'd love some thoughts.
