In response to their post on Reddit, another user explained that certain hydrangeas, like the Hydrangea macrophylla, bloom on old wood. Pruning these too early or too harshly can damage the buds already developed for the season, resulting in a lack of flowers. It’s essential to identify whether your hydrangea blooms on old or new wood to prune them correctly. For Hydrangea macrophylla, pruning should only be done lightly after they flower in late summer or early autumn.
In contrast, hydrangeas like Hydrangea arborescens bloom on new wood and can be pruned more heavily between late fall and early spring. These types are also more cold-tolerant and less prone to winter damage. A variety called ‘Endless Summer’ blooms on both old and new wood, meaning you can enjoy flowers twice a year.
To avoid mistakes, gardeners need to understand the type of hydrangea they have and follow the appropriate pruning schedule. Prune at the right time, and your hydrangeas will reward you with lush, vibrant blooms in the summer.
