Q.My Romeo Cherry Bush Doesn’t Produce Any Fruits..
In the Spring it has a lot of flowers but after flowing branches that had flowers are dying(leaves are all welted and yellow). I have it for 5 years and still do not see any berries.. It is growing in very sunny location and I believe has very good drainage. It is growing next to Pocahontas Lilac bush and Panicle Hydrangea they both doing very well.
