Q.flowering tree was poor this year
I planted tree that has very crimson leaves and like small damsons. After I dug around and put soil around and put flowers for some years, I think that it might be the case why is poor. I’m very worried.
I'm unclear as to the variety of tree that you are having issues with.
Was this a newly planted tree or a well established tree?
Is the tree showing signs of stress following a winter dormancy or did the tree have signs of stress right after you planted the flowers?
