These fertilizers will give all the nutrients and help the tree growing vigorously with a nice look and much denser foliage. FertilizerĬonifer fertilizer is expensive (like 30-15-15 with minor elements) but very effective especially if your soil is sandy. It is also required to keep the soil slightly moist when the plant is young as mature trees can tolerate dry soil. Soil should be well-drained and rich in organic matter. Blue Spruce Careīlue spruce tree care involves a few requirements and slight maintenance to keep it healthy and vigorous. However, blue spruce trees can tolerate less than perfect conditions but growing them in a heavily polluted area can affect the blue color coating of the needles. Planting a blue spruce tree on location in moist soil with full sun to light shade is optimal. If you are planting a blue spruce tree, our recommendation is to buy a plant from nursery so that you’ll not have to wait for that much long. Seedling Growth of blue spruce is also very slow, and you need to be patient. If the length of light falls below 12 hours a day, they become dormant. Blue spruce seeds require a considerable period of light to germinate: 14 to 16 hours per day. Only mature blue spruce trees produce the cones. Air layering of the blue spruce tree is also possible. Once the cuttings show growth, plant them in the right place. These cuttings take a long time to show signs of growth, and you must wait several months, and the success rate is also poor. After planting keep the cuttings in a bright spot and keep the growing medium moist. These cuttings should be dipped in a rooting hormone before planting in containers in a mixture of peat and sand. Propagation and Planting Blue Spruceīlue spruce is usually propagated by cuttings, graftings, and seeds. Blue spruce cuttings are collected, preferably in the morning from vigorous branches. Other Names - Blue Spruce, Green Spruce, White Spruce, Colorado Spruce or Colorado Blue Spruce and Picea Pungens.
