Hydrangeas not Blooming - Knowledgebase Question

Question by mdscoops

I know I didn't spell it correctly, but I think you get the point. Anyway, my husband bought me two blue hydrangeas for Mother's Day from Home Depot three years ago and they have never bloomed. The greens look healthy, but no buds or flowers. I have tried fertilizing them and transplanted them this spring. Any ideas on what might be wrong? Everyhting else I have planted blooms without problem

Florist's hydrangeas are big leaf hydrangeas and these types of hydrangeas bloom on old wood. (Stems are called "old wood" if they have been on the hydrangea since the summer before the current one.) Since big leaf hydrangeas bloom on old wood, if your plants consistently freeze down to ground level each year, they may never produce flowers because there will be no old wood on which new blooming stems can develop. You may want to replace them with a type that blooms on both old and new wood. Endless Summer is one such hydrangea and grows wonderfully well in your gardening zone. Hope this information helps solve the mystery of your non-blooming hydrangeas.
