Plant a skyrocket juniper tree in an area with a sunny exposure that receives at least six hours of sun daily. Although skyrocket juniper trees can tolerate partial shade and a more limited amount of sun, it may make them more susceptible to disease and pest infestation and cause a slower growth rate.
When planting, dig a hole at least two times larger than the tree’s root ball. The hole should be deep enough for the root collar to sit evenly with the surrounding surface of the soil. Add a layer of gravel to the bottom of the hole if the soil does not drain well. This evergreen, which prefers soil that is on the dry side, can grow in sandy or clay soils as long as it is well-drained.
Add compost, and mix it into the soil well. Pack the soil around the root ball to remove air pockets. Water at least once a week and mulch regularly. Skyrocket juniper trees are tall; they are ideal for areas with limited ground space and are often used as privacy borders. When planting a line of trees, space them at least 2 to 2 1/2 feet apart.
Skyrocket junipers are relatively easy to grow, are cold-resistant, and can survive in acidic soil as well as in soil with an alkaline pH level. They are also tolerant of salt spray. Feed them a granular fertilizer in early spring and again in mid-fall. Avoid feeding during the hot summer months.
