Q.Hydrangea Not Flowering
I have a Hydrangea Quercifolia ‘Snow Queen’ that gets filtered sunlight from a large oak and very little direct sunlight. The soil is somewhat sandy. I drip irrigate. Fertilize somewhat regularly. The plant is about 5 feet tall and leggy but healthy although the leafs are not dark green. The plan lives in a cool coastal climate zone. Problem is I am not getting any blossoms and have not for the past two years since it was planted. Question: What can I do to promote flower growth?
Partial sun is needed and many times lack of flowering is due to sunlight and over fertilizing. You can have your soil tested to see if you have too much nitrogen. Too much nitrogen will cause you to have lovely foliage and not flowers.
