Q: Why is my Blue Star Juniper turning green?
A: The most common cause of 'Blue Star' losing its intense blue color is insufficient sunlight. This juniper requires full sun (at least 6 hours of direct sun daily) to produce and maintain its characteristic steel-blue hue . In partial shade, the foliage will fade to a duller green or blue-green.

Q: How large does Blue Star Juniper get?
A: It is a very slow-growing plant. After 10 years, it typically reaches 1-3 feet in height and 3-4 feet in spread . Its mature size can be influenced by growing conditions, with plants in ideal locations reaching the higher end of the range.

Q: How fast does it grow?
A: 'Blue Star' has a very slow growth rate, typically adding only 2-4 inches of new growth per year. This slow growth is one of its key ornamental features, as it allows it to be used in small spaces and containers for many years without needing to be pruned or replaced.

Q: How should I plant and care for it?
A: Plant in full sun in well-drained soil. It is adaptable to a range of soil types, including sandy and rocky soils, but will not tolerate wet, poorly drained conditions. Water regularly during its first year to establish a deep root system. After establishment, it is very drought-tolerant. No fertilizer is typically needed.

Q: Is it a good plant for a rock garden?
A: Yes, it is one of the best conifers for a rock garden. Its slow growth, compact size, striking color, and tolerance for poor, rocky soils make it an ideal specimen for tucking into crevices, cascading over rocks, or massing as a textural ground cover in alpine and rock garden settings .

Q: Can it be used for bonsai?
A: Yes, Juniperus squamata 'Blue Star' is a popular choice for bonsai due to its naturally small, scale-like foliage, slow growth, and the ability to develop interesting trunk and branch character over time . Its intense blue color also makes it a highly desirable specimen.

Q: Is it deer resistant?
A: Yes, junipers are generally resistant to deer browsing due to the prickly texture of their foliage and their strong scent. This makes 'Blue Star' an excellent choice for gardens where deer pressure is a concern .
