I have a small area that contains a hydrangea, azalea and forsythia. This summer all "bolted" and have long leggy tops. What causes this?
This is normally caused by a lack of light. Has a new structure gone into the area that may be blocking light? It may also be that trees in the area have grown or have developed thicker canopies that are blocking light. You may need to thin the canopies of surrounding trees a bit to allow more light in.
Examine the area and think about how you can get a bit more light in. These plants can take shade, but cannot take deep shade. So, only a little work would need to be done to help reduce the deepness of the shade in the area to make it acceptable to these plants.
When do you move hydrangea?
Depending on your region, this can be done in fall or late winter/early spring. While they can transplant fairly easy, make sure it is done while dormant and get as much of the root system as possible.

How and when do you prune hydrangeas?
Generally, this shrub can be pruned in spring or fall, depending on your location and the type of winter weather you receive. Weak or diseased stems should be pruned to the ground while spent flowers and other stems should be cut to the last bud. This article will help you:

People in my neighborhood have the same soil as I do and yet their hydrangeas bloom year and after year with no effort. I have tried all the normal things, pruning, not pruning, fertilizing with compost. The leaf edges have been turning brown for the past few years, which leads me to believe they need more water. They have been in front of my house for the past 10 years and are partially under an overhang, but I do water them. Please can you help?
You may be lacking phosphorus. If there is a lack of phosphorus in the soil, plants will have little to no blooms. You can either use a phosphorus rich fertilizer or add some bone meal to the soil.
