Colorado Blue Spruce Tree

1. Planting: Select an area with direct sunlight for your Colorado Blue Spruce. Though it thrives in full sun, it will also grow in partial shade. Furthermore, a wide range of soil types supports the Blue Spruce - clay, loam, or sandy - provided that the soil is well-drained.

Once you’ve found your ideal area for planting, dig a hole that is shallower than the root ball and at least twice the width. If you’re planting several Blue Spruces together for privacy fencing, ensure you space them at least 10 to 20 feet apart.

To help the soil retain moisture even more efficiently, spread 3 to 4 inches of mulch around the base of the Spruce.

2. Watering: To encourage proper growth, water your newly planted Blue Spruce Trees at least once a week during the first year after planting, until the ground freezes during the winter. More frequent watering may be necessary during the warm summer months to keep the ground adequately moist.

If you’re not sure when to water, simply feel the soil near your tree, down to about a depth of 1 inch. If it feels dry, it’s time to water.

3. Fertilizing: Although Colorado Blue Spruces don’t require frequent fertilizing, an application during early spring (before the growing season) provides an extra boost of nutrients for longer needles and richer color. Use 10-10-10 slow-release fertilizer and follow label instructions.
