We planted an 8' ornamental Cherry three springs ago. We did not expect it to bloom the first year, the second year , again, it didn't bloom so... we thought this year it would, for sure, bloom . Again, it didn't. What could be wrong? RR
It is very much alive. Leafing out beautifully, just no blossoms. When we built here, three years ago, we got the best screened topsoil (with mushroom compost). To answer your question, no we haven't fed it anything this year yet. All the other cherries in our area seem to be blooming, and I don't think all these people have fed their trees. Do ornamental cherries bloom then leaf or can it be the other way around?
If it's a chokecherry (Prunus virginiana) or bird cherry (P. padus) cultivar it leafs out quite a bit before producing spikelike inflorescences, rather than producing rounded bunches or even solitary flowers as the leaves are just starting to come out, in the fashion of Japanese cherries. If you have birds eating the flower buds or winters are too cold for them, you won't get flowers. If you have planted rootstock instead of the scion--sometimes the graft fails and the stock is grown on and sold as the complete unit (stock + scion) by mistake--or the tree you bought is a seedling that is too young to flower you may not have gotten bloom yet for those reasons as well.
