Picea glauca 'Conica' (Alberta Spruce)

How to grow Picea glauca 'Conica' (Alberta Spruce) in NZ

Picea glauca ‘Conica’, or Alberta Spruce, grows well in New Zealand’s cooler climates. Plant in full sun or light shade in well-drained, fertile soil for best results. Water regularly during the first two years, then only in extended dry periods. Feed in spring with a balanced slow-release fertiliser to maintain dense, healthy foliage. Mulch around the base to conserve moisture and suppress weeds, keeping it clear of the trunk. This naturally compact, conical evergreen requires little pruning—only remove damaged growth as needed—making it a perfect choice for formal gardens, borders, and decorative pots.
