Green Pillar Boxwood is a unique, upright evergreen shrub that adds vertical interest to any landscape with its narrow, columnar growth habit. Unlike traditional boxwoods, Green Pillar maintains a slender profile, reaching up to 9 feet tall while only spreading 2 to 3 feet wide, making it perfect for tight spaces, small gardens, or an elegant accent in formal landscapes. Its dense, glossy green foliage stays vibrant year-round, providing consistent color and texture whether planted as a standalone specimen, used in rows to create a living fence or accenting entryways.
This boxwood variety thrives in USDA zones 5-9 and is incredibly versatile, tolerating both full sun and partial shade. Green Pillar Boxwood is also relatively low-maintenance, with a naturally tidy shape that requires minimal pruning to maintain its columnar form. Its adaptability to different soil types and deer resistance make it an excellent choice for various landscape designs. Additionally, it’s highly valued for its durability in colder climates, retaining its vibrant green hue through winter, unlike many other evergreens that tend to discolor.
Ideal for formal gardens, topiary work, or privacy screens, Green Pillar Boxwood is perfect for adding height and structure to your outdoor spaces. With its slow to moderate growth rate, this boxwood requires less upkeep than faster-growing shrubs, allowing it to maintain its elegant, narrow form without frequent pruning.

How to Care for Green Pillar Boxwood
Be sure to read our planting instructions to ensure a healthy and happy Green Pillar Boxwood plant for years to come!
How do I Plant Green Pillar Boxwoods?
To plant Green Pillar Boxwoods, start by selecting a location with well-drained soil and full sun to partial shade, as this ensures optimal growth and vibrant foliage. Dig a hole that is twice as wide and just as deep as the root ball to give the roots ample space to spread. Place the shrub in the hole so the top of the root ball is level with the surrounding soil, and backfill with a mix of native soil and compost for added nutrients. Water thoroughly after planting to help settle the soil and promote root establishment. If planting multiple Green Pillar Boxwoods for a hedge or screen, space them about 2 to 3 feet apart to allow for their narrow, upright growth habit. Once planted, Green Pillar Boxwoods benefit from a layer of mulch around the base to retain moisture and regulate soil temperature. Be sure to keep the mulch a few inches away from the trunk to prevent rot. Water regularly during the first growing season to keep the soil evenly moist but not waterlogged. These boxwoods are relatively low-maintenance, but adding a slow-release fertilizer in early spring will help encourage healthy growth. With the right care, your Green Pillar Boxwoods will thrive, providing year-round structure and vertical interest in your garden.

How do I Water Green Pillar Boxwoods?
To properly water Green Pillar Boxwoods, focus on deep and consistent watering, especially during the first year after planting to establish a strong root system. Water the shrubs deeply once a week, ensuring that the moisture reaches 6-8 inches into the soil. During hot or dry periods, increase the frequency to twice a week to prevent the soil from drying out. It’s important to water at the base of the shrub to avoid wetting the foliage, which can lead to fungal issues. Mulching around the base of the shrub also helps retain moisture and regulate soil temperature, reducing the need for frequent watering. Once established, Green Pillar Boxwoods become moderately drought-tolerant and require less frequent watering. However, during extended dry spells or extreme heat, occasional deep watering will help maintain the shrub’s vibrant, evergreen foliage. Check the soil moisture regularly by digging a few inches into the soil; if it feels dry, it's time to water. Be cautious not to overwater, as boxwoods prefer well-drained soil and can be susceptible to root rot in overly soggy conditions. Proper watering will keep your Green Pillar Boxwoods healthy, ensuring they retain their narrow, upright form and lush appearance year-round.

How do I Prune Green Pillar Boxwoods?
To prune Green Pillar Boxwoods, start by performing light pruning in late winter or early spring, before new growth begins. This timing helps shape the shrub while minimizing stress on the plant. Use clean, sharp pruning shears to remove any dead, damaged, or diseased branches, which improves airflow and promotes healthy growth. Since Green Pillar Boxwoods have a naturally upright and narrow shape, pruning is mainly focused on maintaining this columnar form. Trim lightly along the sides to keep the shrub’s sleek profile, but avoid cutting back more than one-third of the plant at a time to prevent over-stressing. For ongoing maintenance, Green Pillar Boxwoods may require light pruning in the summer to maintain their narrow, formal shape, especially if used as a hedge or accent plant. Regular thinning of the interior branches helps increase light penetration and air circulation, reducing the risk of fungal diseases. Avoid heavy pruning in late fall, as this can encourage tender new growth that may be damaged by winter cold. By following these pruning practices, your Green Pillar Boxwoods will retain their elegant, vertical shape, enhancing the beauty of your landscape year-round.

How do I Fertilize Green Pillar Boxwoods?
To fertilize Green Pillar Boxwoods, apply a balanced, slow-release fertilizer in early spring, just before new growth begins. A fertilizer with an N-P-K ratio of 10-10-10 is ideal for promoting healthy root development and dense, vibrant foliage. Spread the fertilizer evenly around the base of the shrub, ensuring it does not come in direct contact with the trunk to prevent root burn. After applying the fertilizer, water thoroughly to help the nutrients reach the root zone. This annual feeding helps Green Pillar Boxwoods maintain their narrow, upright form and encourages healthy growth throughout the season. For additional support, Green Pillar Boxwoods can benefit from a second, lighter application of fertilizer in mid-summer if planted in poor soil or showing signs of nutrient deficiency. Organic amendments, such as compost or well-rotted manure, can also be incorporated into the soil to naturally enrich it and improve long-term plant health. Regular fertilization ensures that your Green Pillar Boxwoods stay vigorous, with rich green foliage and strong disease resistance. Proper feeding will enhance their overall appearance and allow them to continue providing vertical structure and year-round interest in your garden.
