Montrose Spire Columnar White Spruce

Picea glauca 'Montrose Spire' is a tall, narrow white spruce with a columnar outline and short, light-green needles. Glover Nursery lists a mature size of 20–30 feet tall by 6–10 feet wide and describes the tree as cold hardy and drought resistant once established.

The listed size is approximate; allow space for the tree's eventual height and spread rather than treating it as a small shrub. The nursery lists full sun or partial sun and well-drained soil. ## Growing conditions Choose a sunny to partly shaded site with soil that drains freely. After planting, water the root ball thoroughly and keep it from drying while roots establish. Once established, this selection is described as drought resistant, though prolonged dry weather can still call for supplemental watering. ## Maintenance Avoid planting too deeply and keep mulch away from the trunk. Iseli's general planting guidance recommends a broad planting hole, a visible root flare and careful watering during establishment; adapt watering to local rainfall and drainage.
