The Q&A Archives: Climbing Hydrangeas

Question: I have 3 Climbing Hydrangeas. They look great and are growing like crazy but in the 4 yrs since I planted them they have never blossomed. How do I get this to happen.


Answer: Grow hydrangeas in moist, well-drained soil. They appreciate a high organic content (such as compost) mixed into the soil. Though they grow well in shade, too much shade will retard the development of flowers. Full sun can scorch the leaves so part sun to shade seems best. Winter protection is a good idea.

Most plants that don't bloom can trace their problems to one of four sources: not enough light, deer damage, pruning at the wrong time or bud drop from cold winters or late frosts. One other thought - too much nitrogen fertilizer (or plants that are close to turfgrass that is regularly fertilized). Excessive nitrogen can result in lots of lush, green growth, at the expense of flowers.

Hope this information helps you determine why your plants refuse to bloom.
