Take out any old or straggly canes completely,and cut back the branches that have flowered this year to just above a pair of leaves or their buds. In the older types, you can do this back to leave 3 leaf nodes, but if it is a newer hybrid be less severe.
do you really mean when do you prune a hydrangea?
The answer depends on the type of hydrangea and the climate that it grows in. There are many types of hydrangeas with different pruning requirements.
Some hydrangeas bloom on "old wood" which means the stems and buds develop the prior year. If these buds are cut off (or if they freeze off in cold climates), the plant will not bloom that year or until new wood becomes "old".
Some hydrangeas bloom on "new wood" which means stems with buds that develop in the current growing season. These must be pruned very early in the season so there will be plenty of time for buds to develop for blooming that year.
Some hydrangeas bloom on both old and new wood so some blooming will occur even with pruning. This is mostly prevalent in warmer climates.
Another consideration is why you want to prune. Is the plant too big? Remove dead flowers?
The amount of petals each flower cluster has on a hydrangea varies from plant to plant. The hydrangea is native to southern and eastern Asia and North and South America.
A hydrangea plant is considered to be in the Hydrangeaceae family. There are 70-75 different species of hydrangea. These plants grow primarily in North and South America and North and South Asia.

How much to cut back your hydrangea depends on the variety of hydrangea you have, and where you live. In northern climates "Annabelle" and "pee gee" hydrangeas can be cut back to eight inches, and still produce a three foot-high shrub with flowers during the summer. "Mophead", "Lacecap" and "oakleaf" hydrangeas set their blooms in late August, September or October, so you have to prune them in early August to be sure you aren't cutting off next year's blooms. Prune out up to a third of the stems of an older plant to encourage new growth. Prune those stems to the ground. Otherwise it usually isn't necessary to prune them at all. Just cut off the spent flowers (deadhead) down to the next stem or mature leaf.
Yes, you should prune a desert rose plant, it keeps the plant healthy.

Yes you can prune your goldfish plant. It is best to do it during it's dormant(non-blooming) time.
Prune is just another word for 'cutting' i.e you cut your hair but prune a plant. So prune is to cut shorter.
yes it is .
most spring blooming shrubs require pruning after the blooms are gone, but before fall.
