When to prune hydrangeas – Best time to cut back hydrangea

Pruning your hydrangeas at the right time is one of the most important steps to take for a stunning display in the summer. But, this all depends on what type of hydrangea you have. When should you cut back hydrangeas?

Hydrangeas are a favourite plant amongst British gardeners, beloved for their colourful and shapely blooms.

Famously easy to care for, these plants require very little maintenance, but a good pruning at the right time of year can guarantee plentiful flowers come spring and summer.

Once the temperature warms up a little, and there’s no longer a risk of frost, you should assess your hydrangeas for any frost damage they may have suffered over the coldest months of the year.

If there is frost damage in early spring, prune the plant back, removing any damaged shoots.

Because these two types of hydrangea produce flowers on new wood – unlike mophead and lacehead varieties – you don’t need to worry about over-pruning.

You should prune the plant back leaving just two or three healthy buds on each stem, and take the opportunity to shape the plant, removing crossing stems and neatening up untidy areas.

When should you prune mophead and lacehead hydrangeas?

Because they produce flowers on old wood, these flowers are best to be pruned in mid spring, just before the plant blooms for summer.

Simply prune the old flowers to make space for the new buds.

New buds will form just underneath the old flower head, so trim the old head to give the buds space to grow.

Don’t prune the hydrangea back too hard, as this may damage this summer’s growth.

If your plant is overgrown, this is also a good time to remove some of the overgrown stems at the base of your hydrangea.
