The new plum, a grafted plum we purchased, struggles. Both were infested with aphids last year. The new plum struggled. The old one shook it off without a problem. I was told the old plum is a Stanley, but it's probably a seedling from a Stanley.
I'm starting pears and apples from seed so I have no idea on those yet. But the pear seeds came from my sister's property a few miles away and she doesn't water them. The apple seeds came from a neighbor's yard, ditto.
