Trellises must be sturdy to support the large and heavy vines. Climbing hydrangeas have tendrils that form a firm attachment to almost any type of surface. It is best to avoid growing this vine against walls that need periodic routine maintenance because the vines will not detach easily and will leave pieces of the tendrils attached to the surface when removed.
The vines can also grow into gutters. I have seen old climbing hydrangeas growing on brick walls and chimneys without any problems. The vines will cover the mortar, though, masking any problems. After a mature vine has covered a brick surface and cracks develop in the mortar, the vine will need to be removed to make repairs.
The honey locust tree provides a filtered shade that is good for a climbing hydrangea, while the building may be casting a deeper shade. Most likely, your vines simply need more time and a little extra attention to produce flowers, since your description indicates that they are healthy. Ideally keep them in an unheated greenhouse. Once you see clear signs of growth pot on plants, keeping them in a shady spot. Mulch the plant every spring to aid moisture retention in the soil and water in dry weather in summer.
No flowers Hydrangea petiolaris can take a few years to flower. Lack of flowers on a mature plant could be due to incorrect pruning. Brown spots on leaves This is leaf spot, a fungal infection. Remove any affected leaves as soon as you see them. Make sure you direct water the base of the plant when watering and if possible improve air circulation around it. Brown blobs on leaves, poor growth Hydrangea scale is a sap sucking insect found on hydrangeas.
In severe cases it can cause poor growth and leaf loss. You may spot the eggs, covered in a white waxy material, in early summer. The mature scale insects look like brown blobs. If the problem is serious, spray in July with an organic insecticide based on plant oils or fatty acids. Otherwise birds and other predators will keep populations down naturally.

I planted a climbing hydrangea about five years ago and it has climbed nicely up a wooden fence but refuses to bloom. It is in a spot which receives morning sun. Last year I tried pruning some of it back in an effort to force it to bloom.
I've seen them grown with lovely blooms, which is what prompted me to try it. If it doesn't bloom soon it will hit the compost pile!! I've noticed that Japanese beetles seem to love it in late summer. Any help from you would be most appreciated!
