Care for crabapples, "fruitless" pears, decorative cherries?
My place had a few "fruitless" type landscaping trees here when I moved in. I've trimmed out shoots and anything I thought had to go. But how much do I need to care for these? Can they habor issues that can spread to my actual fruit trees? I'm not sure if they work as pollinators?
There's 1 red leafed/barked (cherry?) tree that we see a lot around here in landscaping because of the pretty pink flowers. There's 2 *I think* flowering crabapple and 1 other with small red berry type fruit and very spaced out branches with small leaves.
Should I be spraying them when I spray the orchard (i.e. copper in the Winter if I'm having a powder issue, etc)? Should I be trimming them each year?
