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.
Same with my plum trees. Must trim them down occasionally............
Also, it has to be 65°F or higher AND SUNNY when they blossom in the spring or there won’t be any bees to pollinate them..............
