watering
Colorado spruce should be watered once per week, providing approximately 1 inch of water each time. During periods of prolonged hot and dry weather, additional water may be necessary, especially if the tree is newly planted or showing signs of wilting. Avoid overwatering since this can lead to root rot. To ensure that the plant is adequately watered, check the soil around the tree weekly with your finger. If the soil is dry more than 2 inches below the surface, then it's time to water.
sunlight
Colorado spruce requires full sun (at least 6 hours per day) during the spring and summer months and partial sun (at least 4 hours per day) during the fall and winter months. ideal growth conditions will be in an area with plenty of direct sunlight. Too much shade can prevent adequate growth and cause for slower tree development, while too much sun can cause the plant to become scorched and overly dry.
pruning
Colorado Spruce should be pruned in the late spring or early summer months when new growth begins to emerge. Generally, no more than 1/3 of the foliage should be removed when pruning Colorado Spruce, but less may be better if desired shape is achieved. Pruning should involve removing shoots with undesirable branch angles, branches that cross and rub on each other, and any dead or diseased branches. Pruning will encourage healthier, denser growth as well as maintain size and desired shape. Be sure to sterilize pruning tools after each cut to avoid transferring diseases.
