Choosing the Right Boxwood Variety

Before you even think about digging, selecting the right boxwood variety is crucial for success. Boxwoods come in various shapes and sizes, each with its own specific growth habits and suitability for different climates and landscaping purposes. Consider the ultimate size and shape you desire, as well as the environmental conditions of your planting site.

Some boxwood varieties are naturally compact, while others are more sprawling. Some thrive in full sun, while others prefer partial shade. Researching different cultivars will help you choose the best boxwood for your specific needs, ensuring it thrives in your garden for years to come.

Popular Boxwood Varieties

Here are a few popular boxwood varieties to consider, each with unique characteristics:

  • ‘English Boxwood’ (Buxus sempervirens): A classic choice known for its dense, compact growth and versatility. It’s a popular choice for hedges and topiary.
  • ‘American Boxwood’ (Buxus sempervirens ‘American’): Similar to English Boxwood, but often grows a bit larger. It’s also a good option for hedges and screening.
  • ‘Japanese Boxwood’ (Buxus microphylla japonica): More tolerant of heat and humidity than some other varieties. It features smaller leaves and a more upright growth habit.
  • ‘Winter Gem’ (Buxus microphylla ‘Winter Gem’): Known for its excellent cold hardiness and vibrant green foliage that holds its color well throughout the winter.
  • ‘Green Velvet’ (Buxus x ‘Green Velvet’): A hybrid boxwood with a rounded shape and a fast growth rate. It is a good option for a quick hedge.

Preparing the Planting Site

Proper site preparation is essential for the healthy establishment of your boxwood shrubs. Boxwoods prefer well-draining soil that is rich in organic matter. They don’t like to sit in soggy conditions, as this can lead to root rot. Good drainage is key to preventing disease and ensuring vigorous growth.

Before planting, assess your soil. You can do this by digging a small hole and observing how quickly water drains. If the water drains slowly, your soil may need amending. Additionally, ensure the planting site receives the appropriate amount of sunlight for your chosen boxwood variety. Most boxwoods prefer partial shade, especially in hotter climates.

Soil Amendments and Drainage

If your soil is heavy clay or poorly draining, you’ll need to amend it to improve drainage and aeration. Here’s how:

  • Add Organic Matter: Incorporate compost, well-rotted manure, or other organic matter into the soil. This improves drainage, adds nutrients, and helps retain moisture.
  • Consider Raised Beds: If drainage is a persistent problem, consider planting your boxwoods in raised beds. This provides excellent drainage and allows you to control the soil composition.
  • Test and Adjust pH: Boxwoods prefer a slightly acidic to neutral soil pH (around 6.0 to 7.0). You can test your soil pH with a soil testing kit. If the pH is too high, you can amend the soil with sulfur or other acidifying agents.

The Planting Process: Step-by-Step

Now that you’ve chosen your boxwood and prepared the site, it’s time to plant. Following these steps will help ensure a successful planting and a healthy start for your shrubs. The best time to plant boxwoods is in the spring or fall when temperatures are milder, and the plants are not stressed by extreme heat or cold.

  1. Dig the Hole: Dig a hole that is twice as wide as the root ball of your boxwood shrub and just as deep. This provides ample space for root growth.
  2. Loosen the Roots: Gently loosen any circling roots around the root ball. This encourages them to grow outward into the surrounding soil.
  3. Position the Shrub: Place the boxwood shrub in the hole, ensuring the top of the root ball is level with or slightly above the surrounding soil. Do not bury the stem.
  4. Backfill the Hole: Fill the hole with the amended soil, gently tamping it down to remove air pockets.
  5. Water Thoroughly: Water the newly planted boxwood deeply and thoroughly. This helps settle the soil around the roots.
  6. Mulch: Apply a 2-3 inch layer of organic mulch, such as shredded bark or wood chips, around the base of the shrub, keeping it away from the stem. Mulch helps retain moisture, suppress weeds, and regulate soil temperature.

Watering and Fertilizing Boxwood Shrubs

Proper watering and fertilization are crucial for maintaining healthy and vibrant boxwood shrubs. Boxwoods require consistent moisture, especially during the first year after planting. However, overwatering can lead to root rot. Finding the right balance is key to their long-term health.

Fertilizing boxwoods helps provide the nutrients they need to thrive. However, over-fertilizing can also be detrimental, leading to excessive growth and making the plants more susceptible to pests and diseases. Understanding the specific needs of your boxwoods will help you establish a successful care routine.

Watering Guidelines

Here are some watering guidelines to follow:

  • Newly Planted Boxwoods: Water newly planted boxwoods deeply and regularly, especially during dry periods. Water when the top inch of soil feels dry to the touch.
  • Established Boxwoods: Established boxwoods are more drought-tolerant but still benefit from regular watering, especially during prolonged dry spells. Water deeply, allowing the water to soak into the soil.
  • Avoid Overhead Watering: Avoid overhead watering, as this can promote fungal diseases. Water at the base of the plant.
  • Monitor Soil Moisture: Use a moisture meter or your finger to check the soil moisture before watering.

Fertilizing Tips

Fertilize boxwoods in the early spring, before new growth begins, and again in late summer. Use a balanced, slow-release fertilizer formulated for shrubs. Avoid over-fertilizing, which can cause excessive growth and make the plants more susceptible to pests and diseases.

  • Choose the Right Fertilizer: Select a fertilizer specifically formulated for shrubs or evergreens.
  • Follow Package Instructions: Carefully follow the instructions on the fertilizer package for application rates and timing.
  • Avoid Over-Fertilizing: Over-fertilizing can lead to leggy growth and make the plants more susceptible to pests and diseases.
  • Water After Fertilizing: Water the plants thoroughly after fertilizing to help the fertilizer reach the roots.

Pruning Boxwood Shrubs

Pruning is essential for maintaining the desired shape and size of your boxwood shrubs. It also helps promote healthy growth and prevents the plants from becoming overgrown. The best time to prune boxwoods is in the late winter or early spring, before new growth begins. Light pruning can also be done throughout the growing season to maintain shape.
