I planted 2 paeonies 2 years ago, in the same border and a matter of about 10 feet apart. Conditions are pretty much identical for both of them. Last year they both grew quite well but had no flowers. This year they are both growing well again but one is smothered in buds and the other doesn't have a single one!
Is there anything I can do this year to encourage the reluctant flowerer, or do I just have to wait another year and hope it works out what to do?
