Planting & Care

Where to Plant

  • Sunlight: Full sun (6+ hours) is best for maintaining a dense, tight habit, though it performs remarkably well in part shade. In hotter climates, a bit of afternoon shade can help prevent the foliage from bronzing during intense summer heat.
  • Soil: These boxwoods thrive in well-drained, loamy soil with a neutral to slightly alkaline pH. If you have heavy clay, plant them in a slight mound or "high" to ensure the crown stays above the water line, preventing the roots from suffocating.

Watering Requirements

For the first two seasons, provide about an inch of water per week to help the root system reach deep into the soil. Once established, North Star® Boxwood is quite drought tolerant, but inconsistent moisture during extreme heat can lead to "leaf cupping" or slow growth. Aim for deep soakings at the base of the plant rather than frequent light sprinkles to encourage a resilient root structure.

Pruning Tips

This variety naturally grows into a tidy globe, so you only need to prune if you want a formal hedge or a specific shape. Because it blooms on old wood, wait until after the spring growth flush has hardened off to trim, which prevents you from cutting off next year's potential. Think of pruning like a light haircut to maintain the "waistline" of the plant and to increase airflow through the center of the branches.

Fertilizer Needs

Apply a balanced, slow release fertilizer or a specialized evergreen food in early spring before new growth begins. Avoid high nitrogen fertilizers late in the summer, as this encourages tender new growth that won't have time to harden off before the first frost. This late season "growth spurt" is easily damaged by winter temperatures, leading to unsightly brown tips in the spring.

Boxwood Care & Maintenance

Planting:

  • Choose a location with full sun to partial shade.
  • Ensure soil is well-drained; amend with organic matter if needed
  • Well-drained average to alkaline soil
  • Space plants 2–3 feet apart for hedges or group plantings.

Care:

  • Water regularly during establishment, then only during dry spells. Boxwood only needs supplemental moisture during drought and water before the winter sets in, as they need this moisture in their leaves to protect them against the drying winter winds.
  • Apply a balanced fertilizer in early spring to encourage healthy growth.
  • Prune or shear lightly in late winter or early spring to maintain shape.
  • Mulch around the base to retain moisture and regulate temperature.

North Star™ Boxwood is the go-to choice for gardeners seeking elegance and ease. Whether you're looking to frame your landscape with lush hedges or add year-long greenery to a small space, this dependable shrub has you covered.
