Cultivation and Care Tips for Wintergreen and Winter Gem Boxwood
When considering the upkeep of both Wintergreen and Winter Gem Boxwood, there are some crucial guiding points. Foremost, it’s vital to understand that these plants thrive best in well-draining soil, alleviating strain on the roots and promoting healthier growth. Under-watering can be as detrimental as over-watering; thus, maintaining a balance is essential. A soak-and-dry method is recommended, where the soil is thoroughly watered, then allowed to dry before the next watering.
Second, these plants appreciate sunlight but also tolerate shade. Ensuring they receive about six hours of sunlight daily will bring about optimal results. However, in zones with particularly intense summers, partial afternoon shade may benefit these resilient shrubs. Moreover, it’s necessary to act against potential pests. Regular inspection for common pests like boxwood leafminers, mites and psyllids helps to keep the plants healthy. Utilizing an organic or chemical pesticide, preferably in the early morning or late evening, aids in pest control.
Finally, while both varieties of boxwood are relatively low-maintenance, pruning is advisable to maintain their dense, compact form. This should be done in late winter or early spring, before new growth begins. While taking care not to prune too much at once, shaping these shrubs annually encourages fuller, more robust growth. These key considerations will ensure that both your Wintergreen and Winter Gem Boxwood flourish, adding aesthetic value to your garden for years to come.
