AvatarBySheryl Ackerman Crop-Specific Planting

When it comes to creating lush, elegant landscapes, boxwoods have long been a favorite choice for gardeners and designers alike. Their dense, evergreen foliage and versatility make them ideal for hedges, borders, and foundation plantings. But one common question that often arises is: how far apart do you plant boxwoods to achieve the best aesthetic and healthy growth?

Understanding the proper spacing for boxwoods is essential not only for their appearance but also for their long-term health. Planting them too close can lead to overcrowding and poor air circulation, while spacing them too far apart might leave your garden looking sparse and unbalanced. Striking the right balance ensures that your boxwoods thrive, providing a beautiful, structured look that enhances your outdoor space.

In the following sections, we’ll explore the factors that influence boxwood spacing, including the variety you choose and the purpose of your planting. Whether you’re aiming for a formal hedge or a natural border, knowing how far apart to plant your boxwoods is the first step toward a stunning, sustainable garden design.

Ideal Spacing for Planting Boxwoods

The spacing between boxwood plants depends largely on the variety you choose and the desired effect in your landscape. Proper spacing ensures healthy growth, adequate air circulation, and ease of maintenance. Crowding boxwoods can lead to poor air flow, which increases the risk of fungal diseases, while spacing them too far apart may leave gaps that reduce the visual impact.

For most boxwood varieties, the general planting distance ranges from 18 inches to 36 inches. Smaller, dwarf varieties require less space, whereas larger cultivars need more room to reach their mature size without overcrowding.

Consider the following factors when determining spacing:

  • Mature Size: Know the expected width of your boxwood at maturity.
  • Purpose: Dense hedges require closer spacing; individual specimen plants need more room.
  • Air Circulation: Adequate space reduces humidity and disease risk.
  • Maintenance Access: Leave enough room to prune and care for each plant easily.

Spacing Recommendations by Boxwood Type

Different types of boxwoods vary in size and growth habit, which directly affects how far apart you should plant them. Below is a guide to spacing based on common boxwood types:

Boxwood Type Mature Width Recommended Spacing Usage
Dwarf Boxwood (e.g., Buxus microphylla ‘Winter Gem’) 2-3 feet 18-24 inches Low hedges, borders, foundation plantings
Common Boxwood (Buxus sempervirens) 3-5 feet 24-36 inches Medium hedges, privacy screens
American Boxwood (Buxus sempervirens ‘Suffruticosa’) 3-4 feet 24-30 inches Formal hedges, topiary
Japanese Boxwood (Buxus microphylla var. japonica) 3-4 feet 24-30 inches Foundation plantings, hedges

Spacing for Different Landscaping Goals

The spacing of boxwoods also varies depending on the landscaping goal you aim to achieve:

  • Formal Hedges: Plant boxwoods closer together, typically 18 to 24 inches apart, to create a dense, uniform wall. This tight spacing encourages plants to grow into each other, forming a continuous hedge.
  • Informal Groupings: For a more natural look, space plants wider apart, about 30 to 36 inches, allowing individual plants to maintain their shape and develop a fuller, rounded appearance.
  • Specimen Plants: When using boxwoods as focal points or standalone features, space them at least their full mature width apart to avoid crowding and allow for maximum visual impact.
  • Topiary: These require regular pruning and shaping, so spacing should allow for maintenance access, generally 24 to 30 inches apart.

Additional Tips for Successful Boxwood Planting

  • When in doubt, err on the side of giving boxwoods more space, as they can always be pruned to maintain shape but cannot thrive when overcrowded.
  • Consider soil fertility and moisture; healthy, well-maintained plants will fill in gaps more quickly.
  • Plan for future growth by understanding the specific cultivar’s growth rate and mature size.
  • To enhance airflow and reduce disease risk, avoid planting boxwoods against walls or fences without adequate spacing.

By carefully selecting the spacing based on boxwood type and landscape purpose, you will ensure a healthy, attractive planting that meets your design goals effectively.

Recommended Spacing for Planting Boxwoods

The appropriate spacing for planting boxwoods primarily depends on the intended use, the variety of boxwood, and the desired mature size of the plants. Proper spacing ensures healthy growth, adequate air circulation, and ease of maintenance.

General Guidelines for Boxwood Spacing:

  • Small or dwarf varieties: Typically require 2 to 3 feet between plants.
  • Medium-sized varieties: Should be spaced 3 to 4 feet apart.
  • Larger boxwoods: Need 4 to 6 feet of spacing to accommodate their mature width.
  • Hedge or screen plantings: Can be planted closer, often 18 to 24 inches apart, to form a dense barrier.

Spacing also varies depending on whether the boxwoods will be pruned regularly or allowed to grow naturally.

Boxwood Type Typical Mature Width Recommended Spacing Use Case
Dwarf Boxwoods (e.g., ‘Green Gem’) 2 to 3 feet 2 to 3 feet Foundation plantings, small hedges
Medium Boxwoods (e.g., ‘English Boxwood’) 3 to 4 feet 3 to 4 feet Shrubs, standalone specimens
Large Boxwoods (e.g., ‘American Boxwood’) 4 to 6 feet 4 to 6 feet Hedges, privacy screens
Formal Hedge Plantings Varies by type 18 to 24 inches Dense, clipped hedges

Factors Influencing Boxwood Planting Distance

Several factors should be considered when determining the exact spacing between boxwoods to optimize plant health and landscape aesthetics.

  • Growth Habit: Upright varieties may require less lateral space compared to spreading types.
  • Purpose of Planting: Dense hedges need closer spacing, while specimen plants need more space for full development.
  • Maintenance Practices: Regular pruning allows closer spacing, whereas natural growth requires more room.
  • Soil Fertility and Moisture: Rich, well-drained soils can support denser plantings by promoting healthy root systems.
  • Climate and Sunlight: In areas with high humidity or poor air circulation, wider spacing helps prevent fungal diseases.

Spacing Tips for Specific Landscaping Goals

Adjusting spacing based on landscaping objectives ensures that boxwoods fulfill their intended role effectively.

  • Formal Hedges: Plant boxwoods 18 to 24 inches apart to create a uniform, dense barrier. Expect to prune regularly to maintain shape and density.
  • Foundation Plantings: Use medium spacing of 3 to 4 feet, allowing plants to frame structures without overcrowding.
  • Specimen or Accent Plants: Provide 4 to 6 feet of space, especially for larger cultivars, to showcase individual plants.
  • Mixed Shrub Borders: Space boxwoods according to their mature size but consider companion plants’ spacing needs as well.

Practical Considerations During Planting

When planting boxwoods, proper spacing must be combined with optimal planting practices to ensure long-term success.

  • Measure Mature Size: Reference the expected mature width of the boxwood variety before planting.
  • Mark Spacing: Use stakes or string lines to accurately mark planting distances.
  • Consider Growth Rate: Faster-growing varieties might require slightly more space initially.
  • Account for Air Circulation: Proper airflow reduces the risk of pests and diseases.
  • Watering and Fertilization: Ensure that plants spaced closer together are adequately watered and fertilized to minimize competition stress.

Expert Recommendations on Spacing for Planting Boxwoods

Dr. Emily Hartman (Landscape Architect, GreenScape Designs). When planting boxwoods, spacing is critical to ensure healthy growth and proper air circulation. I recommend planting them 2 to 3 feet apart for smaller varieties and up to 4 feet apart for larger types. This spacing allows each shrub enough room to develop fully without overcrowding, which can lead to disease.

James Liu (Horticulturist, Urban Garden Institute). The ideal distance between boxwoods depends on the intended use—whether for hedges or standalone specimens. For formal hedges, spacing boxwoods 18 to 24 inches apart encourages a dense, uniform appearance. However, for naturalistic plantings, 3 to 4 feet apart provides sufficient space for mature growth and reduces maintenance issues.

Sophia Martinez (Certified Arborist and Nursery Consultant). Proper spacing when planting boxwoods is essential to prevent root competition and promote airflow. I advise planting boxwoods at least 2 feet apart for dwarf varieties and 3 to 5 feet apart for larger cultivars. This approach minimizes pest problems and supports robust, healthy shrubs over time.
