I have a willow in the back garden not sure what variety, but I my best guess is Goat Willow. I understand these can be aggressively pruned, but if I prune it right now, will it stay bare for the whole summer? It seems top-heavy, but I don’t want an empty trunk until next year. I have attached a pic and am thinking of pruning it where I have added the red line, to remove all of the messy clumps of new sprigs from previous years. What do you think?
