Spring is the best time to prune Hydrangeas

A short guide to rejuvenating neglected Mop head and Lacecap Hydrangeas.

There are many shrubs that need to be pruned during early spring, Mop head and Lacecap Hydrangeas are included in this group. These Hydrangeas flower in mid to late summer on wood that was produced in the previous year.

Here is step by step guide to pruning these useful garden shrubs:

  1. Identify the new shoots from the old shoots. The new shoots are a darker brown colour than the older stems which are a pale brown-beige colour. The new shoots often grow on top of the old shoots. One of the aims of pruning these Hydrangeas is to encourage / increase the growth of new shoots from the base of the plant rather than on top of old wood.
  2. On a well maintained plant, all that is needed is to cut back the spent flower heads to the first strong pair of leaf buds in early spring.hydrangea pruned to the base

  6. Cut back any spent flower heads to the first strong pair of buds on the stems you have decided to keep.
