The time to prune native honeysuckle is immediately after flowering has finished for the year, at the expense of some of its berries. If the plants are pruned in spring, this will delay flowering, and may cause it to cease altogether. After flowering, growth can be cut back by up to a third. Harder pruning may affect the number of flowers produced the following year, so this should only be done if more space is needed in the garden. If the plant has become a tangled mess, it can be rejuvenated by cutting back to 20in (50cm) above ground level at the start of spring. This will give it time to grow strong new shoots, flowering the following year.
