Colorado Blue Spruce Care
The Colorado blue spruce thrives in full to partial sun. It can tolerate partial shade, but it does better in those spots with plenty of sunshine. These spruces love moist, well-draining soil. Poorly draining soils can result in limited growth or root rot. You may need to add soil amendments for a more fertile growing environment. However, this spruce is not fussy about soil pH levels.
This species of spruce is tolerant of droughts, and it can survive with limited water. You will want to avoid waterlogging the tree. Any watering should be used sparingly, and there should be plenty of time for the tree to soak up all that excess water. Young trees should be watered during those harsh dry spells. You can also add garden mulch around the tree to help retain moisture. Since this tree is a native of Colorado, it is very tolerant of colder weather. In some cases, it can tolerate heat. However, the tree is not suitable for those sweltering and humid climates.
The Colorado blue spruce does not need frequent fertilizer. In the spring, fertilize the tree before the growing season. If you want to increase the needles’ color and length, then some fertilizer could be applied for additional nutrition. Slow-release granular fertilizer is the best choice and should be used near the root zone. To prevent burning from the fertilizer, you want to add two inches of water around the trunk.
These spruce trees do not need to be pruned. However, you can prune to promote a denser foliage. Since these trees are used for Christmas decorating, many people choose to add them as potted landscaping plants. After the holiday, you can add them permanently to your space. Once the season is finished, dig a hole and keep the dirt loose to provide enough air for the roots.
