The Q&A Archives: Climbing Hydrangea Won't Flower

Question: I have a climbing hydrangea that has been in the ground for about 5 years. It grows pretty well (although a little slow) but it has never flowered. Do you know why or have any suggestions?

Answer: Climbing hydrangea can be slow to establish, and will flower best if it receives at least 6 hours of sunlight. If it is not blooming, yours may not be getting quite enough sunshine. Climbing hydrangea performs best in acidic to neutral, well-drained soils with high fertility. It is moderately drought resistant, and prefers light afternoon shade but if the soil is kept moist, full sun is acceptable. The growth can be very slow until the plant is established.

If sunlight isn't an issue, perhaps improper pruning is to blame. Climbing hydrangea requires little or no pruning, perhaps only to thin or direct growth. If you've pruned your plant, that may explain why it is not blooming for you.

Hope this information helps you determine just why your hydrangea won't bloom for you.
