tree peony with weak stems
Not a regular visitor to this forum but hoping for an answer for my computer phobic mother. She has a yellow tree peony, about 4 years old that is not able to hold up the flower blooms. The beautiful flowers are buried amongst the leaves. It seems to be healthy otherwise, is this a badly bred plant; is there anything (short of splinting the stems)that she can do ie, pruning, fertilizer??? I'm sorry but I don't know the cultivar or where she got it. Appreciate any insight you care to offer.
