Pruning Hydrangeas (part 2 of 2)

Pruning Hydrangeas (part 2 of 2)

Hydrangeas are currently undergoing huge changes as plant breeders introduce new kinds that are dwarfer than the older ones and that produce flowers on the new shoots each year which will make pruning much easier in the future. But if you have an established plant you need t pay a bit more attention to pruning.

Hydrangeas need pruning for two reasons: to remove the old flowerheads and keep them tidy and to reduce their size.

The best way to prune a hydrangea is to wait until the worst of the winter weather is over (hopefully by now!) and then remove all the old flowerheads, cutting back to a pair of nice, fat buds. Then look at the plant carefully and cut out a few of the oldest, twiggiest shoots back to near the base.

Do not remove more than a third of these old stems every year. This thins out the growth, allows new growth to form and keeps the plant manageable, youthful and healthy. If you cut all the stems back to the base and make a huge plant tiny in one fell swoop it will send up lots of strong stems and your plant will be almost as big by the end of summer but with very few blooms. So take your time and prune every year. A mulch and dressing of fertiliser after pruning won’t go amiss either.
