Sea Green Juniper: A Low-Maintenance Evergreen Shrub
Botanical Description
The Sea Green Juniper (Juniperus × pfitzeriana ‘Sea Green’) is a popular hybrid coniferous shrub known for its unique cascading form and environmental tolerance. It is a relatively small shrub, reaching heights of 4 to 6 feet at maturity, with a spread of 6 to 8 feet.
Growing Conditions
Light: Sea Green Junipers thrive in full sun, but they can tolerate partial shade. Too much shade can lead to excessive moisture buildup and fungal issues.
Soil: This adaptable shrub is not picky about soil type, but it prefers well-draining soil with a slightly acidic to neutral pH. Heavy soils require less frequent watering, while lighter soils need more.
Water: Water your Sea Green Juniper regularly, especially during the first year after planting. Allow the soil to dry out slightly between waterings. Avoid overwatering, as this can lead to root rot.
Hardiness: Sea Green Junipers are hardy in USDA hardiness zones 4 to 9, making them suitable for a wide range of climates. They can tolerate various temperatures and environmental conditions.
Care and Maintenance
Pruning: Sea Green Junipers require minimal pruning. If desired, prune in early spring to shape the cascading form or reduce the height. Avoid over-pruning, as this can ruin the shrub’s natural beauty.
Fertilizing: Fertilize your Sea Green Juniper with a balanced fertilizer in the spring. This will help promote healthy growth and lush foliage.
Pest and Disease Resistance: Sea Green Junipers are generally resistant to pests and diseases, but they can occasionally be affected by bagworms or blight. Treat any infestations promptly to prevent damage.
