When should you cut back Cotoneaster?
After flowering, lightly cut back any branches that spoil the symmetry of the plant. In autumn, trim back lightly to reveal fruit and maintain a tidy shape. Avoid hard pruning, as it can reduce flowering and berry production the following season. Fruit bushes such as currants and gooseberries will benefit from thinning out, while perennials that lack decorative seed heads should be cut back to the ground. Autumn is also the time to prune tender plants such as lavender and rosemary, which won’t withstand pruning in winter.
