Plant Care

Colorado Blue Spruce requires minimal maintenance once established. Water deeply but infrequently, allowing soil to dry between waterings. Apply a layer of mulch around the base to retain moisture and suppress weeds, keeping it away from the trunk. Fertilize in early spring with a balanced, slow-release fertilizer formulated for conifers.

Prune dead or damaged branches as needed, and shape lightly in late winter or early spring before new growth appears. Monitor for potential pest issues such as spider mites or needle cast disease, though these trees are generally resistant to most problems.

Planting Instructions

Select a planting location that provides adequate space for mature growth and receives full sun. Dig a hole twice as wide as the root ball and equally deep. Remove the tree from its container and gently loosen the roots. Place the tree in the hole, ensuring its straight and at the same depth it was growing in the container.

Backfill with original soil mixed with organic matter, tamping down gently to remove air pockets. Create a water basin around the tree and water thoroughly. Apply a 2-3 inch layer of mulch around the base, keeping it away from the trunk.
