Answer: Grafting shouldn't affect the flowering and fruiting of your old plum. It could be that this particular tree is a different variety from the wild and other plums in your yard, so it's blooming at different times or just not compatible with the other plums. You should annually prune your plum trees and fertilize in spring with a complete fertilizer such as 10-10-10. For more details on growing fruits trees contact your local County Extension Office (715-373-6104).
