Trimming should be done immediately after flowering stops in summer, but no later than August 1. If you want to cut off new buds, do not do it during the fall, winter, or spring.
When leaves emerge in the spring, tip-pruning the branches can encourage multiple, smaller flower heads. If your plants look like they’re ready to be trimmed, they are. If they don’t look ready, you may need to wait until the next growing season.

How far back do you prune a hydrangea?
Make sure to retain some healthy branches if you want to avoid losing all the flowers. A bigleaf hydrangea can be trimmed back by one-third of its total mass, but it will weaken the shrub and cause it to fall over.
If you want to prune back a large branch, you can use a pair of tweezers to pull the branch away from the rest of the plant. If you don’t have a tweezer handy, use your fingernail to gently pry the branches apart. Be careful not to damage the surrounding foliage, as this can cause the entire plant to wilt.
Which hydrangeas should not be cut back?
Hydrangeas that bloom on old wood do not need pruning and are better off for it. If you leave them alone, they will bloom more profusely the next year, but if you cut them too much, you will end up with a bunch of blooms that don’t bloom at all the following year.
Should I cut off Brown hydrangea blooms?

Pruning is one of the reasons why your hydrangeas are not flowering. Hydrangas in the Spring and Summer: In the spring and summer, you will want to remove any dead or dying leaves from the plant.
This will help to reduce the amount of water that is lost to evaporation during the summer months. In the fall, the leaves will begin to turn brown and fall off. You can use a sharp knife to cut off the dead leaves, or you can cut them off with a pair of tweezers. Once you have removed all of the foliage, it is time to begin the process of removing the stems.
The stems should be removed as soon as possible, but not too soon. It is best to leave them in place for a few days to allow the soil to dry out. After the roots have been removed, they will need to be pruned back to a more manageable size. Pruning can be done in a variety of ways, depending on the type of plant you are trying to grow.
Can you cut hydrangeas back too far?
In late winter or early spring, these shrubs can be cut all the way back to the ground. Many gardeners prefer smaller blooms on a regular basis, even though smooth hydrangeas will produce much larger blooms if they are pecked hard like this each year. In the spring and summer, the shrub produces a large number of small, white flowers.

Be careful not to puncture your fingers while you are doing this. Once you have removed all leaves and stems, place the whole plant back in the pot and cover it with plastic wrap. Allow it to sit for a week or two to allow the roots to grow back into the soil.
Where do you cut back hydrangea stems?
Prune to just above a pair of healthy buds on each stem. If you want a natural look or want to add a bit of color to your plant, you can cut back the healthiest buds. Plant in a well-drained pot with good drainage.
Water well, but don’t let the soil dry out too much or you’ll end up with a pot that’s too wet and won’t be able to support the weight of your plants. If you’re growing in containers, make sure they’re at least 6 inches deep and have drainage holes in the bottom.
