PLANT DESCRIPTION & MATURE SIZE

The Moonglow Juniper, also known as Moonglow Rocky Mountain Juniper, is a striking evergreen valued for its silvery-blue foliage and narrow, pyramidal form. This low-maintenance conifer adds year-round color, privacy, and vertical structure to landscapes while staying tidy and naturally upright. Highly drought tolerant and cold hardy, Moonglow Juniper is a favorite for privacy screens, windbreaks, and modern landscape designs.

GROWTH RATE & MATURE SIZE:

Moderate growth rate; reaches a mature height of 15–20 ft
and mature width of 6–8 ft.

WATERING & SUNLIGHT

Water deeply once per week during the first growing season to establish roots. After establishment, water every 2–3 weeks depending on heat and rainfall. This juniper is drought tolerant once mature and prefers soil to dry slightly between deep waterings. Plant Moonglow Juniper in full sun for best growth and brightest silver-blue foliage. Too much shade can cause thinning and duller color.

PLANT CARE & PLANTING INSTRUCTIONS

PRUNING:
Moonglow Juniper requires very little pruning. If needed, lightly trim in late winter or early spring to maintain its natural shape and remove any dead or damaged branches.

FERTILIZING:
Apply a balanced, slow-release fertilizer in early spring to support healthy growth and strong blue foliage color.

WINTER PROTECTION:
Moonglow Juniper is cold-hardy in its growing zones and generally does not require special winter protection. Mulching around the base can help protect roots in colder climates or during extreme cold snaps.

PLANTING INSTRUCTIONS:

Dig a hole twice as wide as the root ball and no deeper than the soil line. Place the tree so the top of the root ball sits level with surrounding soil, loosen any circling roots, and backfill with native soil. Water thoroughly after planting and apply mulch in a wide ring around the base, keeping mulch away from direct contact with the trunk. Continue deep watering during the first growing season to establish a strong, drought-tolerant root system.

USDA GROW ZONE:

Zones 3-7

Moonglow Juniper thrives in cold to moderate climates and is especially well-suited for northern, mountain, and high-plains regions. It handles snow, wind, and freezing temperatures with ease and performs best in dry to moderately moist, well-draining soils. This juniper is highly adaptable and excels in areas with low humidity and full sun exposure. In warmer climates near its upper zone limit, excellent drainage and airflow are essential to prevent stress.

All California orders require a mandatory inspection by the Texas Department of Agriculture (yep, it’s a USDA thing!). These inspections happen about once a week—typically on Tuesdays, though the day can vary. If you place an order just after an inspection, your plant may not ship for several days until the next one. Unfortunately, we’re not able to expedite this part of the process.

Also, due to USDA regulations, we’re unable to ship oak trees, citrus or fruit trees (except olive trees) to California. This rule helps prevent the spread of pests and diseases and applies to nurseries across the country.

Thanks for your patience—we’ll make sure it’s worth the wait.
