Will Hydrangeas Grow Back If Cut Down?

The 6 types of hydrangeas above are divided into 2 main groups: those that bloom on the old stem and those that bloom on the new stem.

Old stems are branches that were developed before the current season, and new stems are branches that are growing in the current season.

Therefore, this distinction is very important in pruning hydrangeas after each crop to ensure that the plant will bloom brilliantly in the following seasons.

Popular types of hydrangea – Hydrangea macrophyllas such as mophead, bigleaf, and rencap are varieties that can flower on older stems.

If you’re growing them in a temperate climate, you don’t need to prune them to stimulate leaf and flower growth the next season as they will continue to flower from the old stems from the previous crop.

However, if the pruning is to help reduce the size of the bush, it can be done within a few weeks immediately after the hydrangea has flowered. Pruning branches and leaves in late summer gives the tree time to develop buds for next summer’s blooms.

Also, the rest of the hydrangeas have new-stem flowering properties, so you may feel more comfortable pruning the old ones to let the plants focus their energy on growing new ones and flowering.

You should prune these hydrangeas in the fall or winter, even if you prune them to the ground, they will continue to grow again and flower next spring.

However, you should be aware that pruning branches close to the ground will weaken the trunk, so it’s a good idea to stake or have a plan in place to protect the young branches that are growing against the negative effects of weather in winters such as snow, high wind, storm or rain.


The pruning of hydrangeas depends on the variety that blooms on the old or new stem to continue doing. For hydrangeas that flower on old stems, you only need to prune broken branches, and yellow leaves to reduce the size of the bush as well as focus energy on healthy branches to flower.

For hydrangea varieties that flower on new stems, you can feel free to prune the old branches, but you need to make sure the bush is healthy and has large branches to support in windy or heavy rain.
