How to Care for Green Mountain Boxwood
Before you purchase your Green Mountain Boxwood, be sure to read the recommended care instructions to ensure your plant remains happy and healthy for years to come.
How do I plant Green Mountain Boxwoods?
To plant Green Mountain Boxwoods, begin by selecting a location that offers partial to full sun and well-drained soil, as these shrubs thrive in sunny to lightly shaded environments. Start by digging a hole twice as wide and as deep as the root ball to allow the roots to establish. Gently remove the shrub from its container, loosen the roots, and place it in the hole, ensuring the top of the root ball is level with the surrounding soil. Backfill the hole with a mix of native soil and organic compost, tamping it down to remove any air pockets. Water the plant thoroughly after planting to help the roots settle. If planting multiple Green Mountain Boxwoods for a hedge or border, space them 2 to 3 feet apart for optimal growth. After planting, apply a 2-3 inch layer of mulch around the base of the Green Mountain Boxwood to help retain moisture and regulate soil temperature, while keeping the mulch a few inches away from the trunk to avoid rot. Water the shrub deeply once a week during its first growing season to encourage strong root development. Once established, Green Mountain Boxwoods are relatively low-maintenance and can tolerate drought, making them a great choice for formal hedges, foundation plantings, or accent shrubs in various landscape designs.
How do I water Green Mountain Boxwoods?
To properly water Green Mountain Boxwoods, focus on deep, infrequent watering, especially during their first year after planting. Water the shrub deeply once a week, ensuring the soil is thoroughly moistened but not waterlogged. Green Mountain Boxwoods prefer well-drained soil, so allow the top few inches of soil to dry out between waterings to prevent root rot. During particularly hot or dry periods, you may need to increase the watering frequency slightly to help the plant establish a strong root system. Deep watering encourages the roots to grow deeper into the soil, promoting a healthier, drought-tolerant plant. Once established, Green Mountain Boxwoods become more drought-tolerant and require less frequent watering. In most cases, natural rainfall will provide sufficient moisture, and supplemental watering will only be necessary during extended periods of drought. To help retain moisture and reduce the need for frequent watering, apply a 2-3 inch layer of mulch around the base of the shrub, keeping it a few inches away from the trunk to prevent rot. Proper watering practices will ensure that your Green Mountain Boxwoods maintain their vibrant green foliage and healthy growth, enhancing your landscape year-round.
How do I fertilize Green Mountain Boxwoods?
Fertilizing Green Mountain boxwoods properly is key to maintaining their lush, dense growth and rich green color. The best time to fertilize Green Mountain boxwoods is in early spring, just as new growth begins, using a balanced, slow-release fertilizer specifically designed for evergreens. A fertilizer with an N-P-K ratio such as 10-10-10 or 10-6-4 works well for promoting both root development and foliage density. Spread the fertilizer evenly around the root zone, which is the area beneath the drip line of the shrub, taking care to avoid direct contact with the trunk to prevent root burn. Once applied, thoroughly water the area to help the nutrients absorb into the soil and reach the roots effectively. Conducting a soil test before fertilizing Green Mountain boxwoods can help determine if any nutrient deficiencies exist and ensure the pH level is within the optimal range of 6.5 to 7.0. If deficiencies are identified, supplement the soil with the necessary amendments to create the best growing conditions for your boxwood. In addition to spring fertilization, a light application of fertilizer can be made in mid-summer to encourage growth, but avoid late-season fertilization, as it can lead to new growth that may not harden off before winter. Proper fertilization of Green Mountain boxwoods promotes their dense growth habit and vibrant color, ensuring they remain an attractive, structured element in your landscape throughout the year.
How do I Prune my Green Mountain Boxwood?
Pruning Green Mountain boxwoods is essential for maintaining their natural conical shape and ensuring a dense, healthy appearance. The ideal time to prune Green Mountain boxwoods is in late spring or early summer, after the risk of frost has passed. Begin by removing any dead, damaged, or diseased branches to promote airflow and reduce the risk of pests or diseases. Use sharp pruning shears to shape the boxwood, trimming back overgrown areas while keeping the shrub’s natural form. Focus on making gradual, even cuts to prevent a scalped look, which can lead to bare spots. Avoid cutting into old wood, as Green Mountain boxwoods do not regenerate well from heavy pruning. For the best results, prune Green Mountain boxwoods with a goal of maintaining their iconic pyramidal or conical shape. Ensure that the top is slightly narrower than the base, allowing sunlight to reach all parts of the plant and promoting growth throughout the shrub. Pruning lightly and regularly is better than infrequent, heavy pruning, as this encourages compact, bushy growth. Prune only the tips of new growth to refine the shape and keep the boxwood looking formal and tidy. Proper pruning of Green Mountain boxwoods will enhance their natural structure, providing year-round interest in both formal gardens and foundation plantings.
