Planting Tips

Where to Plant

Columnar Blue Spruce thrives in an area that receives full sun to light shade. It’s perfect for spots where vertical accentuation is desired, like corners of buildings, entryways, or in narrow garden beds.

Light

Full sun is ideal for this spruce, ensuring the most vibrant blue coloring of its needles. It can tolerate light shade, but this may slightly affect the intensity of its foliage color.

Soil

Well-drained soil is crucial for the health of Columnar Blue Spruce. It's adaptable to a range of soil types, including sandy, loamy, and clay soils, provided they drain well.

Spacing

Space these trees about 6-7 feet apart. This allows each tree enough room for growth and maintains the distinct, narrow form of each individual tree.

When to Plant

The best time to plant Columnar Blue Spruce is in early spring or fall. Planting during these cooler seasons helps the tree establish roots before the stress of summer heat or winter cold.

How to Plant

Plant at the same depth it was in the container. Loosen the soil around the planting hole to encourage root expansion. Water thoroughly after planting to settle the soil.

Plant Care Tips

Watering

Regular watering is important during the first year after planting. Once established, Columnar Blue Spruce is relatively drought-tolerant but may benefit from occasional watering during extended dry periods.

Fertilizing

Fertilize in early spring with a slow-release, balanced fertilizer to support healthy growth. Avoid over-fertilizing, as this can lead to excessive growth at the expense of the plant’s form.

Pruning

Pruning is generally not necessary, as Columnar Blue Spruce naturally maintains its shape. If needed, prune in late winter or early spring to remove any dead or damaged branches.

Spring Care

In spring, check for any winter damage and prune as necessary. Apply fertilizer to encourage new growth.

During summer, ensure adequate watering during dry spells to maintain health and appearance.
