The fastest spreading juniper is the Skyrocket juniper (Juniperus scopulorum ‘Skyrocket’). This beautiful evergreen tree can grow at an impressive rate, reaching a mature height of thirty feet and a mature width of eight feet. If you’re looking to add some height and texture to your garden or landscape, the Skyrocket juniper is an excellent choice.
To successfully grow a Skyrocket juniper, there are a few key factors to consider. Let’s dive into them:
1. Location: Choose a spot in your garden or landscape that receives full sun for at least six hours a day. Skyrocket junipers thrive in sunlight and may not grow as well in shady areas.
2. Soil: These trees are adaptable to a wide range of soil types, including clay, loam, and sandy soils. However, they prefer well-draining soil. If your soil is heavy and poorly draining, consider amending it with organic matter, such as compost, to improve its drainage.
3. Water: While Skyrocket junipers are relatively drought-tolerant once established, they will appreciate regular watering during their first year of growth. Provide them with deep, thorough waterings once a week, especially during hot and dry periods. After the first year, you can reduce the frequency of watering, allowing the soil to dry out slightly between waterings.
4. Mulching: Applying a layer of organic mulch around the base of the tree can help conserve moisture, suppress weed growth, and insulate the soil. Use a three to four-inch layer of mulch, making sure to keep it a few inches away from the trunk to prevent moisture-related issues.
5. Pruning: The Skyrocket juniper has a naturally narrow, columnar growth habit, requiring minimal pruning. However, you can selectively prune any dead, damaged, or crossing branches to maintain its shape and promote good air circulation. Pruning is best done in late winter or early spring before new growth begins.
6. Fertilizer: Skyrocket junipers typically don’t require regular fertilization. However, if you notice signs of nutrient deficiency, such as yellowing leaves, you can apply a balanced slow-release fertilizer in early spring. Be sure to follow the package instructions for proper application rates.
7. Pests and diseases: Skyrocket junipers are generally resistant to most pests and diseases. However, they can occasionally be affected by spider mites or juniper scale. Regularly inspect your trees for any signs of infestation, such as webbing or discolored foliage. If necessary, treat the affected areas with an appropriate insecticidal soap or oil, following the product instructions.
In my personal experience, I have found Skyrocket junipers to be relatively low-maintenance trees. Their fast growth rate can quickly fill in empty spaces in a garden or provide a striking vertical element in a landscape design. Their narrow form also makes them suitable for planting in tight spaces or as a natural screen or hedge.
Remember to always consider the mature size of the Skyrocket juniper when selecting a planting location. Give it enough space to grow and avoid planting it too close to structures or other plants that may become overshadowed or crowded.
With the right care and conditions, the Skyrocket juniper can thrive and become a stunning focal point in your garden or landscape. Its rapid growth rate and unique appearance make it a popular choice among gardeners and landscapers alike.
