If you’re interested in growing Blue Spruces in your yard this season, we have some tips for growing healthy, strong blue spruce trees.
When you’re planting blue spruce trees, choose a sunny location with moist, well-drained fertile soil. They will often tolerate dry wind and can survive in relatively dry soil.
As you set the tree and its bundled roots into the hole in your yard, the hole should be about as deep as the root ball and about two or three times as wide. Consider mixing in a little organic compost when you replace the soil if the soil isn’t very fertile. Fill the hole halfway first, and then fill it with water; doing so will allow the soil to settle and removes all of the air pockets. Before filling the rest of the hole, wait for the water to drain.
As your tree grows and adapts to your soil, you’ll need to water the soil when it becomes dry. You’ll also need to lay about 2 to 3 inches of mulch beyond the tree’s canopy without it touching the trunk.
Water your blue spruce once a week during the summer after you plant it. After the first year, you’ll only need to water the tree when it’s hot and dry outside; avoid wetting the needles. You can also sprinkle one to two cups of slow-release fertilizer around the base of the tree each spring. Settle the fertilizer into the first inch of soil using a rake.
Be sure to keep an eye on your tree as it grows and look for signs of pests such as spider mites that often target blue spruces. You should also look for needle cast which is a disease that often targets blue spruce trees. This disease results in discoloration in the lowest needles on the tree and slowly works its way up. Moist, mulched soil and natural enemies such as predatory mites can be purchased at most local hardware stores to help prevent these issues.
