Blue Arrow Juniper is characterized by its narrow, columnar growth habit, reaching heights of up to 12 feet and widths of just 2-3 feet at maturity. Its dense, blue-green foliage provides year-round interest, making it an excellent choice for vertical accents in landscapes.
This evergreen shrub thrives in full sun and well-drained soil, though it can tolerate a range of soil types, including sandy or rocky soils. Once established, Blue Arrow Juniper is drought-tolerant and relatively low-maintenance, requiring minimal watering and pruning.
Growth Rate of Blue Arrow Juniper
The growth rate of Blue Arrow Juniper can vary depending on several factors, including climate, soil conditions, and maintenance practices. In optimal growing conditions, Blue Arrow Juniper typically grows at a moderate rate, adding approximately 6-12 inches of height per year.
However, it’s essential to note that the growth rate may slow with age, especially once the plant reaches maturity. Additionally, environmental stressors such as drought or poor soil quality can hinder growth, so providing proper care is crucial for ensuring steady development.
Size Considerations
At maturity, Blue Arrow Juniper can reach heights of 10-12 feet, with a width of just 2-3 feet.

Additionally, container planting is an option for those with limited space or those seeking to control the plant’s size.
Tips for Promoting Healthy Growth
To ensure the health and vitality of your Blue Arrow Juniper, follow these tips:
- Watering: Provide deep, infrequent watering, allowing the soil to dry out between waterings to prevent root rot.
