This cultivar has a distinctive columnar shape, with a slender and upright habit that reaches heights of up to 10 feet when left unpruned. The plant’s leaves are small and glossy, with a dark green hue that retains its color throughout the year, earning it the common name “evergreen boxwood.” Although this cultivar doesn’t produce showy flowers, it does produce small and inconspicuous blooms in the spring that are a valuable source of nectar and pollen for pollinators.

Plant cultivation and care

Preferred growing conditions

One of the reasons the Buxus sempervirens ‘Dee Runk’ is so popular is due to its hardiness and adaptability. This cultivar can thrive in USDA hardiness zones 5-8, making it a suitable plant for most parts of the United States.

It prefers to grow in partial sun or partial shade and requires well-draining soil that is moist but not waterlogged. Boxwoods can even tolerate a range of soil types, including sandy, clay, and loamy.

Potential pest and disease issues

While boxwoods are generally easy to care for, they can suffer from some pest and disease issues. Some of the common pests that affect Buxus sempervirens ‘Dee Runk’ include boxwood psyllids, spider mites, and leafminers.

In terms of diseases, the plant is susceptible to root rot, leaf spot, and blight. However, the best way to prevent these issues is by practicing good cultural techniques, such as ensuring proper drainage, avoiding overwatering, and monitoring for signs of infestations.

Planting and maintenance tips

When planting Buxus sempervirens ‘Dee Runk,’ it’s essential to make sure the soil is well-draining and has a pH between 6.5 and 7. In terms of spacing, this cultivar should be planted at least 2-3 ft apart to allow for ample air circulation.

Once planted, the plant requires regular watering until it establishes itself, after which it can tolerate drought conditions. Pruning is crucial for maintaining the plant’s columnar shape and preventing it from becoming too tall or wide.

Ideally, pruning should be done in early spring or late fall, using a sharp pair of shears. It’s important to remember not to over-prune, as this can stress the plant and leave it vulnerable to diseases.

In conclusion, the Buxus sempervirens ‘Dee Runk’ is a fantastic option for gardeners who want a tall and elegant boxwood that can adapt to various growing conditions.

Boxwoods are popular evergreen shrubs with a long history of cultivation.

The Buxus sempervirens ‘Dee Runk’ is one of the most distinct cultivars, renowned for its upright, columnar habit and glossy green foliage. In this article, we will delve deeper into the propagation methods and adaptations of this remarkable plant.

Plant propagation methods

Propagation is essential for gardeners looking to propagate more boxwood plants. Luckily, there are two primary methods of propagation: sexual and asexual reproduction.

1. Sexual Reproduction

Sexual reproduction involves the pollination of boxwood flowers, resulting in the production of seeds.

However, it is worth noting that boxwoods are dioecious, meaning that male and female flowers grow on separate plants. Therefore, to produce seeds, gardeners need at least one male plant and one or more female plants.

The resulting seeds are relatively small and can take months to germinate under optimal conditions. 2.

Asexual Reproduction

Asexual propagation is a more reliable method of reproducing boxwoods and is commonly used by gardeners and nurseries. The two primary methods of asexual propagation are cuttings and layering.

– Cuttings

Cuttings involve taking a stem or branch from an existing boxwood plant and rooting it to form a new plant. Softwood cuttings are the most commonly used type of cuttings for boxwoods and are taken in late spring or early summer when the stems are still young and flexible.

To take a cutting, choose a healthy branch and cut it from the plant at an angle just below a node. Remove all the leaves from the bottom half of the cutting, leaving the top leaves untouched.

Dip the base of the cutting in rooting hormone powder and plant it in a pot filled with well-draining soil. Keep the soil moist and place the pot in a warm, bright spot with indirect sunlight.

In a few weeks, roots should begin to develop, and the cutting will establish as a new plant. – Layering

Layering involves bending a branch or stem of a boxwood plant down to the ground and covering it with soil.

Over time, roots will grow from the stem at the point where it touches the soil. Once the roots have developed, the new plant can be cut from the parent plant and potted up.

Plant adaptations to different environments

One of the many reasons why boxwoods are so popular is due to their adaptability to different environments. The Buxus sempervirens ‘Dee Runk’ is no exception.

Here are some of the key ways in which boxwoods adapt to different environments:

1. Soil

Boxwoods can grow in a wide range of soils, from acidic to alkaline, from sandy to clayey, and from well-draining to poorly-draining soils.

However, it’s important to ensure the soil is well-draining and has a pH between 6.5-7. Poorly-drained soil can lead to root rot, while soils that are too acidic or alkaline can affect nutrient uptake.

2. Climate

Boxwoods can grow in a wide range of climates, from cool temperate regions to subtropical areas.

However, they prefer a temperate climate, not too hot and not too cold. The Buxus sempervirens ‘Dee Runk’ is hardy to USDA zones 5-8 and can tolerate cold winters with snow and ice.

3. Sunlight

Boxwoods can grow in both full sun and partial shade, but they prefer partial shade.

Full sun can lead to leaf scorch, while too much shade can affect growth and cause plants to become leggy. 4.

Drought resistance

Boxwoods are drought-tolerant and can go for long periods without water. However, they prefer moist, well-drained soil, and watering during dry spells will benefit the plant.

In conclusion, the Buxus sempervirens ‘Dee Runk’ is a remarkable plant that adapts well to different environments. Whether propagated through sexual or asexual means, the plant can be grown in a wide variety of conditions.

Its adaptability to different soils, climates, sunlight levels, and drought conditions makes it an attractive option for gardeners and landscapers. With proper care and maintenance, the ‘Dee Runk’ cultivar of boxwood can add beauty and elegance to any garden.
