Have just this past two years grown hydrangeas abd would like to know if they are to be pruned or ut back..tha

STEP 1: Prune hydrangeas after the danger of hard frost is over, but before the new buds begin to swell. STEP 2: Remove all of the old, gray colored wood all the way down to the base of the plant. Leave only the shiny tan or brown colored flower bearing stalks. STEP 3: Trim the flower-bearing wood down to 24 - 36". The ideal shape for a pruned hydrangea is that of a vase, open in the center for maximum air circulation. Keep 5 - 10 stalks of last year's new wood coming up from the base of the plant. Anything that has formed a branch is at least two years old and should be removed. STEP 4: Rake and clean the soil surrounding the pruned hydrangea when you are finished. Lay down a thick layer of mulch to prevent weed growth and moisture loss throughout the growing season. Tips %26amp; Warnings

If you want blue flowers, fertilize with aluminum sulfate. For red flowers, use super phosphate. Fertilize soon after pruning by dibbling the dry fertilizer into the soil around the base of the plant.

Hydrangeas require plenty of water and a shady location in hot summer climates.

I love hydrangeas and usually cut off the blossoms after they are all dried and bring them in the house. They will last you all winter and are beautiful. I don't usually prune them. Be careful of very strong winds tho when the blossoms are on as they might bend way over which is what happened to mine. I hope mine straightens back up in the spring. I have one by my bird feeder and the Cardinals love it.
