Colorado Blue Spruce Planting Guide
The Colorado blue spruce tree is one of the more popular American conifers. In part that is due to its iconic silver-blue needles, as well as its refreshing pine scent.
Depending on how and where it is planted, blue spruce trees can grow anything from 9 to 21 meters tall. Typically they are either planted in a row to form a windbreak or privacy screen, or individually as an ornamental tree.
If you know what you’re doing, it is actually quite easy to plant and grow blue spruce trees. And if you don’t, just keep reading this guide to find out what you need to know.
Selecting a Location
The first thing you need to do is to pick the right location for your Colorado blue spruce tree. And when you do there are several factors that you need to take into account:
Blue spruce trees require lots of light, so you should pick a sunny location where they’ll ideally get at least 6 hours of unfiltered sunlight every day.
Although blue spruce trees are quite adaptable, they prefer moist but well-drained soil. It is recommended that you test the drainage before planting it and add some compost while planting. A soil pH of 6.0 to 7.5 is preferred.
- Temperature and humidity
Being a relatively hardy plant, the Colorado blue spruce can tolerate cold and can also tolerate heat – up to a point. However, it does not do well in excessively hot or humid conditions.
Young blue spruce trees require regular watering, but once the tree is established it won’t require as much. At most you may need to water it during dry spells and make sure that it doesn’t get waterlogged.
If you take into account all these factors when choosing a location for your blue spruce tree, you should be able to easily find the best spot.
How to Plant a Blue Spruce
As long as you take it to step by step, planting blue spruce really isn’t that difficult. In fact, here’s exactly what you need to do:
- Dig a planting hole that is as deep as the root ball and two or three times its width.
- Check the soil and make sure its drainage is good, then add some compost into the mix if necessary.
- Remove the blue spruce from its container by squeezing the sides to loosen the root ball then firmly but gently lifting it from the container.
- Place the blue spruce in the planting hole with the top edge of the root ball at or above ground level.
- Fill in the soil mixture and tamp it as you do so that you remove air pockets.
- Water the planting area by flooding it to settle the soil as well as remove any more air pockets.
It should be noted that the same steps also apply if you’re planting your Colorado blue spruce in a pot. The only difference is that you should prepare the pot by lining the bottom with shade cloth or landscape fabric - as opposed to digging a planting hole.
If you carefully plant your blue spruce in the right location and by following the steps listed above, they shouldn’t require too much additional care. Aside from watering it regularly while it is young, you can choose to lightly fertilize it.
Typically blue spruce trees do not need to be pruned, but you can trim them slightly to shape or remove any branches. Aside from that all you need to do is sit back and wait for it to grow.
