Colorado Blue Spruce seeds are relatively easy to germinate and grow. The dormancy within the seed is short and easily broken and reasonable success can be expected even when seeds are sown without any form of pre-treatment.
Colorado blue spruce germination only takes 10 to 14 days, but the seedlings take their own sweet time to gather their strength. They can grow up to about 4 inches during the first year, and growth will accelerate after that.
The Colorado blue spruce grows at a slow to medium rate, according to the Arbor Day Foundation, although it picks up a bit as it gets older. This blue spruce grows from 12 to 24 inches a year. So it will require 30 to 60 years for a Colorado blue spruce to grow from seed to 60 feet tall.. . . . .364011234558!]0000000000000009783314145283!]
