What to prune in spring

Spring can be the busiest time of year for gardeners. Once day length and temperatures increase, our plants surge into growth. In addition to soil preparation, seed sowing and planting, there is also plenty of pruning to be done. Dogwood, lavender and sea holly are just some of the plants that should be pruned in spring.

Shrubs with colourful stems

Shrubs with colourful stems. Decidous shrubs that benefit from hard pruning, include: Cornus alba, C. sericea and C.sanguinea; ornamental rubus; willows. Use a pruning saw to remove the previous year’s stems right down to the base. This will encourage strong, young growth that has the most vividly coloured bark.

Summer-flowering shrubs

Summer-flowering shrubs. Decidous shrubs that flower on new growth include: Buddleja davidii; French lavender; Lavatera; hebes. Use secateurs to cut back hard to reduce the size and tidy the shape. This will encourage vigorous, flowering shoots. Prune any shrubs that flower after July, in spring.
