Should they not be trimmed every so often to encourage new growth like we do citrus trees? They quit making and we have to trim them back drastically to spur new growth.....................
I don’t actually know. I have never trimmed them and they sometimes produce huge amounts.
Now I have a plum tree in back which has developed some kind of scale on the bark. It is always peeling and hard. No plums in several years. I wonder if there is anything I can do?
Anyone.
