I purchased an Endless Summer hydrangea from you at least 6 years ago. The plant is very healthy, however it does not bloom like it should. The most blooms I’ve ever had in one season is 3. So far this year there is only one and there are and no buds developing. What is it lacking? It gets plenty of sun. And it seems to demand a lot of water as the leaves often droop if not watered. What nutrients would you recommend?

There are several reasons that a healthy hydrangea is flowering as it should. Usually, it has to do with the wrong fertilizer. I recommend a fertilizer that is high in phosphorous, the middle number on the NPK ratio. Phosphorous helps hydrangeas grow flowers. If you are using a fertilizer that is high in nitrogen, your hydrangea will grow lush leaves at the expense of flowers. Pruning at the wrong time runs the risk of cutting off the flower buds. It’s best if you give your hydrangeas room to grow and avoid pruning altogether.
