• Balanced Fertilizer: Select a balanced, slow-release fertilizer specifically formulated for woody plants. An N-P-K (nitrogen, phosphorus, potassium) ratio of 10-6-4 or similar is suitable for boxwood.

• Application Timing: Apply fertilizer in early spring before new growth begins or in late fall to support the plant’s winter resilience. Avoid fertilizing during the peak summer months, as this can lead to excessive tender growth that is susceptible to damage.

• Even Application: Distribute the fertilizer evenly around the drip line of the plant, avoiding direct contact with the stems. Water the area thoroughly after applying the fertilizer to facilitate nutrient absorption.

• Container-Grown Boxwood: Boxwood plants grown in containers, including the ‘Joy’ variety, benefit from more frequent fertilization, as nutrients in the potting mix can deplete over time. Apply a balanced liquid fertilizer according to the manufacturer’s instructions throughout the growing season.

Soil

The soil composition and quality significantly impact the growth and performance of boxwood, including the ‘Joy’ variety. Here are important considerations related to soil for optimal boxwood cultivation:

• Moisture Retention: Boxwood thrives in moist, well-drained soil. Amending heavy or compacted soils with organic matter, such as compost or peat moss, improves drainage and moisture retention.

• Soil pH: The preferred soil pH for boxwood ranges from slightly acidic to slightly alkaline, typically around 6.5 to 7.5. Conduct a soil test to determine the pH of the planting area and adjust it if necessary using appropriate amendments.

• Nutrient Availability: Ensuring that the soil has adequate nutrient content supports the growth and resilience of boxwood plants. Regular applications of organic mulch and periodic fertilization contribute to maintaining soil fertility.

• Soil Compaction: Prevent soil compaction around boxwood plants, as compacted soil restricts root growth and inhibits essential oxygen uptake. Regular aeration and gentle cultivation around the root zone promote healthy soil structure.

• Container Considerations: When growing boxwood in containers, select a well-draining potting mix formulated for woody plants. Regularly monitor soil moisture in containers, as they can dry out more quickly than garden beds.

Pruning

Proper pruning is essential for maintaining the shape, density, and overall health of boxwood plants, including the ‘Joy’ variety. Pruning also helps manage the size of the shrub and promotes air circulation within the canopy, reducing the risk of disease. Here are some key points to consider when pruning boxwood:

• Pruning Time: The best time to prune boxwood, including the ‘Joy’ cultivar, is in late winter to early spring before the onset of new growth. This timing allows the plant to recover and initiate new growth promptly.

• Rejuvenation Pruning: Periodic rejuvenation pruning can benefit older or overgrown boxwood plants, renewing their vigor and overall appearance. This involves cutting the entire plant back to approximately 6 to 8 inches in height, allowing fresh growth to emerge.

• Pruning Tools: Use sharp, clean pruning tools, such as hand pruners or hedge shears, to ensure precise cuts and minimize the risk of damaging the plant tissue. Disinfect the tools between each cut if the shrub shows signs of disease.

• Shape Maintenance: Regularly trim boxwood to maintain the desired shape and size, whether it’s a formal hedge, topiary, or individual specimen. Light, frequent pruning is generally preferable over heavy, infrequent pruning, as it minimizes stress on the plant.

• Internal Thinning: Periodically thin out the interior branches of boxwood to promote air circulation and light penetration. This helps prevent the development of dense, vulnerable foliage that is prone to disease.

• Stem Structure: When pruning boxwood, consider the natural growth pattern and stem structure of the plant. Trim the outer portions slightly more than the inner branches to maintain a balanced, healthy appearance.

Propagation

Boxwood propagation can be carried out through several methods, including stem cuttings, layering, and seeds. Each approach has its advantages and challenges, and the success rate can vary based on factors such as timing and environmental conditions. Let’s explore the key propagation methods for boxwood:

• Stem Cuttings: Propagation from stem cuttings is a popular and reliable method for generating new boxwood plants. Take 4- to 6-inch semi-hardwood cuttings in late summer to early fall, ensuring that each cutting has several leaf nodes.

• Rooting Medium: Dip the base of the cuttings in a rooting hormone to encourage root development, then plant them in a well-draining rooting medium, such as a mix of perlite and peat moss. Maintain consistent moisture and humidity to support successful rooting.

• Layering: Air layering, where a portion of the stem is induced to develop roots while still attached to the parent plant, is another effective propagation method for boxwood. This technique is typically carried out in early to mid-summer.

• Seed Propagation: While boxwood can be propagated from seeds, it is a slower and less reliable method compared to vegetative propagation. Harvest seeds from mature fruit in the fall, and sow them in a seed-starting mix, ensuring consistent moisture and warmth.

• Transplanting Propagated Plants: Once the cuttings or layering have developed strong root systems, carefully transplant them into individual pots or prepared garden beds. Provide appropriate care and observation as the young plants establish themselves in their new environment.
