Since the Colorado Blue Spruce grows well in a wide variety of climatic regimes, they can be panted nearly nationwide, from Zones 2 to 8, and from the wet to the dry. They prefer a moderate amount of moisture, and like full sun. The spruces can be planted singly, in clumps, or in lines as for screens and windbreaks. The growth rate is typically slow, averaging a foot a year, but that can vary from six inches to two feet also. Improved growth rates come from good planting conditions, adequate moisture during the growing season, limited competition from weeds, and a shot of fertilizer a couple times during the year.
Colorado Blue Spruce seeds really don't need any pretreatment, but soaking the seeds in cool to room temperature water overnight does help to assure a more uniform germination. Seeds can also be soaked, drained, and stored in the refrigerator for 14 to 30 days, before planting. That will help overcome any residual dormancy the seeds may have.
Because damping-off is a serious risk with these (as with all conifers), use a sterile of nearly sterile media, like the standard vermiculite, peat moss, perlite, and clean sand. Combining these can be done also. Be careful not to overwater them, and plant the seeds and cover about 1/4 inch with media. Next, cover the seeds with a mulch layer, but so does covering the container or flat with newspaper and keep them in a partly shaded and protected spot as they sprout.
Sprouting will take place very quickly within a couple weeks in many cases. Protect the seedlings with partial shade for the first season, and transplant in late fall or early winter. Gallon containers will work fine for the next couple of years, and because these trees grow slowly, they will need to potted or planted where they can grow for two to five years before they should be outplanted.
One of the interesting things about Colorado Blue Spruce seeds is that seedling color will vary from the true-blues to deep green. There is a wide range of colors among the Colorado Blue Spruce found in its natural environment, and especially true when growing seed from the many varieties. If you collect seeds from the Super-Duper Blue, the seeds will likely revert to the original strain.
