I have a pair of large (roughly 30' tall I guess) cherry trees. They're mossy. They don't produce well (at least not for the 2 seasons we've had them for). What they do produce is so high that I can't net or harvest the fruit safely. The branches are a mess.
I don't know the age (we've only owned the home for a year and a bit), and I get the impression from our neighbors and the overall state of the yard that the former owners weren't all that concerned with upkeep.
The birds get most of the fruit now, but the few cherries that are low enough to harvest are delicious.
- Can I aggressively prune them? When, how, and how much? Am I hoping for too much to want to get the trees down to about 15-20 feet tall?
- Is the moss a problem? Should I just pull it off, or do I need to treat it with something?
