For the past two years my hydrangea plant is green and healthy and about 3-4ft tall. But no blossoms for two years, what is wrong? I fertilize once in the spring with regular granule for hydrangeas and other acid loving plants. It is not near the lawn so does not get nitrogen from lawn fertilizer.
There are several species of hydrangeas. You will have to identify the type you are referring to. Some reasons for no bloom include improper pruning, cold damage which kills flower buds but often not leaf buds so you have a living plant with lush foliage but no flowers, (site may be more susceptible to cold), and too much nitrogen fertilizer.
If you have Hydrangea macrophylla, bigleaf hydrangea, the most common type, this can be susceptible to cold damage.
