Buxus Green Gem is a popular evergreen shrub cherished by gardeners all over the world. With its compact growth, vibrant green foliage, and versatile nature, Green Gem has become a staple in many gardens across the country. It belongs to the Buxaceae family and is native to East Asia. It was introduced to New Zealand as an ornamental shrub, valued for its attractive appearance and ability to be shaped into various forms. Its popularity is attributed to its adaptability to different soil types and its ability to withstand both full sun and partial shade conditions. Buxus Green Gem is a slow-growing evergreen shrub that typically reaches a height of 1 to 1.5 meters. It features small, glossy, dark green leaves and has a dense growth habit, making it ideal for hedging and topiary. The plant produces inconspicuous, small yellow-green flowers in spring, which are followed by insignificant fruit.
 
Location
Green Gem thrives in well-draining soil and is suitable for a range of locations, including formal gardens, borders, hedges, and containers. It can tolerate both sun and partial shade, but excessive exposure to hot afternoon sun should be avoided.
 
Watering
While established plants are reasonably drought-tolerant, regular watering is crucial during dry periods, especially for newly planted shrubs. Water deeply at the base of the plant, allowing the soil to dry slightly between waterings.
 
Feeding
To maintain healthy growth, it is recommended to fertilise Green Gem in spring and early autumn. Use a balanced slow-release fertilizer or organic alternatives, following the instructions on the packaging.
 
Overwintering
Buxus Green Gem is generally hardy in New Zealand, but young plants or those grown in exposed areas may benefit from protection during harsh winters. Consider mulching the base of the plant and covering it with horticultural fleece to safeguard against frost damage.
 
Pruning
Regular pruning is essential to maintain the desired shape and density. Prune in late spring or early summer, after the risk of frost has passed. Avoid severe pruning during winter to prevent potential cold damage. Trim the shrub lightly and frequently to encourage bushy growth.
 
Propagation
Buxus Green Gem can be propagated through semi-hardwood cuttings taken in late summer or early autumn. Dip the cuttings in rooting hormone and plant them in well-draining soil. Keep the soil consistently moist until the new plants establish themselves.
 
Birds & Bees
While the plant's inconspicuous flowers may attract some bees, it is not a significant source of nectar for pollinators. It can provide a habitat for various beneficial insects.
 
Diseases and Pests
Buxus Green Gem is susceptible to a few diseases, including box blight and boxwood leafminer, although typically much more resistant than some of its cousins. Regular monitoring, proper hygiene practices, and prompt treatment with appropriate fungicides or insecticides can help if anything appears.
