FAQs

How big do juniperus squamata blue star get? ›

'Blue Star' Singleseed Juniper is a cultivar that is a dwarf conifer, an evergreen, and slow-growing shrub that may reach from 1 to 3 feet tall and 1 to 4 feet wide. The shrub forms a compact, dense mound.

Blue Star juniper care is a cinch if you plant the shrub correctly. Transplant the seedling into a sunny location in the garden. Blue Star does best in light soil with excellent drainage, but it won't die if it doesn't get it. It will tolerate any number of problem conditions (like pollution and dry or clay soil).

This slow-growing plant is a dwarf, forming a compact mound that reaches just 1 to 3 feet in height at maturity.

It grows extremely low to the ground, reaching a full height of 10-50 cm with a spread of 1.5-2.5 metres in 10 to 20 years. It requires no pruning.

Juniper trees live a long time, some reports show they can be thousands of years old in some cases. A 100-year-old juniper is quite common.

It is commonly called “singleseed juniper” because each bluish, berry-like, female cone contains but a single seed. Like other junipers, it is cold-hardy, thrives in full sun to part shade, and requires good drainage. Once established, this shrub tolerates droughts, and dry, shallow rocky soil.

Euphorbia, Agapanthus, Echinacea, Russian Sage, and Clematis all grow well in the same conditions Juniper prefers, with little extra irrigation needed once the plants are fully established. Plant Hellebores, Japanese Anemone, blueberry, and rose shrubs to provide late fall foliage color and early winter flowers.

How often to water your Blue Star Juniper. Blue Star Juniper needs 0.8 cups of water every 9 days when it doesn't get direct sunlight and is potted in a 5.0" pot.

Late winter or early spring is prime time for feeding your Blue Star Juniper. It's waking up from its winter nap and is hungry for nutrients. A balanced 10-10-10 fertilizer is a good choice for young plants in their first year. Established junipers are less needy; a layer of compost might just do the trick.

Why is my Blue Star Juniper turning yellow? ›

Watering your Blue Star Juniper is less about frequency and more about consistency. If the top two inches of soil feel like a desert, it's time to water. Conversely, if it's soggy, give it a break. Overwatering suffocates roots, leading to yellow leaves, while underwatering leaves them high and dry.

Types of Creeping Juniper

'Blue Forest': A compact variety that spreads one to five feet in ten years. Its foliage changes color from lavender in winter to blue in spring.

Juniperus squamata 'Blue Carpet' is easy to grow and holds an RHS AGM for its exceptional garden performance. Height: 50cm (20"). Spread: 2.5m (8').

The Blue Point Juniper is an attractive evergreen conifer with dense, bright blue foliage that grows naturally in a conical form with no pruning necessary. As conifers go, it is considered fast growing, adding maybe a foot or so in height per year until it reaches maturity at 12 to 14 feet in height.

Common juniper, like most conifers, is usually planted during mild weather of spring or early fall. The rate of growth varies somewhat by variety, but most are slow-growing shrubs, rarely adding more than about 6 inches per year.
