Can I now cut back my hydrangeas, and feed in the spring??

Question

I cut back hydrangeas after blooming last year and fed them in spring, and have very few blooms this year. Also, exactly what fertilizer to use?

Answer 1

It sounds like you have Hydrangea macrophylla. This one flowers on old wood, so pruning any branch that has not flowered, or if the frost kills it back to the ground, will keep it from flowering properly. It's important to know what type of hydrangea you have as that determines when to prune if pruning is needed.

As far as fertilization goes, they generally prefer an all purpose food, but sometimes it is good to only feed them fertilizers high in phosphorus and potassium.
