Use in landscaping projects
Blue spruce (Picea pungens 'Glauca') is a showpiece tree for squares, parks, building entrances, corporate headquarters and large gardens. The silvery-blue colour of its needles contrasts strongly with other plants, so it is used as a focal point. Many cities also plant it as a living Christmas tree in public spaces, decorated year after year.
Planting and spacing
Blue spruce needs space: at maturity it reaches 10–15 m in height and 4–6 m in width, so it should be planted at least 4–5 m from buildings and other trees. It prefers sunny sites and slightly acidic, well-drained soils.
Care and maintenance
It is very frost-hardy and needs no pruning; only dead branches at the base may be removed. In the first years after planting, water regularly during dry spells. In very hot, dry summers it can be attacked by spider mites, so watering and periodic checks are recommended.
