One of the confusing aspects of hydrangeas is that some bloom on old wood growth, while others bloom on new wood growth. The familiar Hydrangea macrophylla, which has large pink and blue flowers, as well as oakleaf hydrangeas and Hydrangea quercifolia, bloom on old wood. These varieties typically start blooming in early summer and end the blooming cycle in midsummer. Because flower buds for the next year start to form by late summer as temperatures cool, it is important to prune them just as the flowers fade. The earlier they are pruned after blooming, the larger next year’s blooms are likely to be.
Varieties that bloom on new wood include Hydrangea arborescens and Hydrangea paniculata, which feature white, conical flowers. These varieties grow and set buds during the same year in which they bloom. Because this process requires time, they only start blooming in midsummer and continue until the first frost. So long as pruning is not undertaken as the flower buds are wakening in spring or going dormant in the late fall, these shrubs will accept pruning at any time of year.
