Prune blue spruce tree
Spruces have individual, angled needles with brown pegs at the base of each needle. The pegs remain on the twig after the needles drop, resulting in a rough twig. Buds are scattered along the twigs of the newest growth. Cones are long and pendulous. Although spruces need very little pruning, bottom branches may die with age and can be removed.
- For a formal shape, prune new growth in the spring. Shear in late spring, after new growth has expanded.
- To reduce the size of a branch, cut back to a lateral branch or a visible dormant bud. This can be done at any time.
- To repair a broken leader, cut off the broken branch and tie one of the shorter side shoots upright onto a splint, training it to become the new leader. Remove the tie after one year. If two leaders develop, remove the weaker one.
