Q. Climbing Hydrangea

My very old climbing hydrangea was growing on our garage. A neighbor said it had been planted 30 years ago. Unfortunately, during this snow storm, most of it came off. It is still partially connected. What should I do?

As long as the vines are intact, I would recommend simply tying it back onto the surface, if you can. If it is against the surface, it will re-attach itself. If the vines are damaged or you cannot somehow set it against the surface, it will most likely need to be cut back.

Q. Pruning

My climbing hydrangea has gotten very full at the tips of the branches. Is this a time to prune those? They make a mess of leaves and not too many blossoms.

These are usually pruned back in the fall, though it should be ok to prune back some in spring if needed. This article has information on pruning hydrangea plants: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/prune-hydrangea-bushes-hydrangea-pruning-instructions.htm

Q. Climbing Hydrangea

I have two climbing Hydrangeas on two different fences planted almost side by side. One of these bloom very well every year, while the other one has never had even one bloom on it in three years. The one that blooms resembles a lace-cap hydrangea in appearance and is quite lovely. I have no idea why the one plant simply will not bloom at all. Both plants receive the the exact amount of light and water since they are both planted in the same location.

Q. Acid Fertilizer for Hydrangea Vine

What acid fertilizer is good for a hydrangea climbing vine? It is a couple years old and had one bloom last year. How do I increase the blooms?

There are several things that can affect the blooming. This article can help: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/hydrangea-not-blooming.htm

I would give it a phosphorus heavy fertilizer instead to promote blooming.

Q. Hydrangea Vines

There are brown spots on my hydrangea leaves.

Various fungal spots can develop on hydrangea leaves and are normally triggered by too much or too little water. Spots also develop when hot sun strikes wet foliage. Water only when the soil is dry and use drip irrigation, if possible. You want the water to soak into the soil and not get on the foliage, which can lead to these fungal problems. You can also retain soil moisture by using mulch. For the fungus, treat the shrub with a neem oil foliar spray.

Q. Hydrangea Plants Have Never Flowered

I have three hydrangea bushes and one hydrangea vine. None of them have ever flowered. I would like to know how to get them to produce flowers.

The soil around the non-blooming hydrangea may be lacking in phosphorus. That can affect the ability of the plant to bloom. These articles will help you learn more:

Q. Climbing Hydrangea-Why No Blooms?

I planted a climbing hydrangea 3 years ago. While the leaves appear to be very healthy, and it puts out new shoots and is planted in a shady, but well light area (perfect), it has never produced a flower! I do not know if it is white or pastel. It is very healthy. I feed it Miracle Grow for blooms; however, it never produces a bloom. It came from Lowes. I never have pruned the plant.

Climbing hydrangea sometimes can take a few years to get blooming after being plants. I would give it some phosphorus though to see if you can get it jump started. Bone meal is a great source of phosphorus.
