Shrubs vs. Bushes: A Comprehensive Guide to Horticultural Differences and Landscaping Uses

by Zuzana
written by Zuzana

Shrubs vs. Bushes: A Horticultural Distinction

Horticultural Definitions

In horticulture, the terms “shrub” and “bush” are often used interchangeably, but there are subtle distinctions between the two. A shrub is generally defined as a woody plant with multiple perennial stems that may be erect or close to the ground, with a mature height of less than 15 feet and stem diameters of less than three inches. A bush, on the other hand, is typically described as a plant that forms a specific shape, with stems and leaves that may be almost touching the ground.

Shrub vs. Bush Foliage

Another way to differentiate between shrubs and bushes is through their foliage. Evergreen shrubs and bushes retain their leaves throughout the year, while deciduous ones lose their leaves in the fall. Additionally, some bushes have stems and leaves that grow close to the ground, while shrubs tend to have thicker foliage and a more upright growth habit.

Location-Based Distinction

The setting of a plant can also influence its classification as a shrub or a bush. Some gardeners consider plants cultivated in gardens to be shrubs, while those growing wild are considered bushes. However, there are exceptions to this rule, such as rose bushes and blueberry bushes, which are typically found in cultivated gardens.

Shrubs vs. Bushes in Landscaping

Both shrubs and bushes are commonly used in landscaping for various purposes. Shrubs are often chosen for their ornamental value, such as their flowers, foliage, or shape. They can be planted as individual specimens or grouped together to create hedges or borders. Bushes, on the other hand, are often used in naturalized plantings or as understory plants in woodland gardens. They can also be used to create dense thickets for privacy or wildlife habitat.

Shrubs, Bushes, and Hedges

Shrubs and bushes are often planted close together to form hedges, which are used for a variety of purposes in landscaping, such as privacy fencing, property line demarcation, or visual division of outdoor spaces. Hedges can be tall or short, evergreen or deciduous, and flowering or non-flowering, depending on the plant species used.

Popular Shrubs and Bushes

One of the most popular evergreen shrubs is the boxwood, which is known for its versatility and ease of shaping. It is often used in topiaries and hedges. Other popular shrubs include hydrangeas, azaleas, and rhododendrons, which are valued for their showy flowers. Common bushes include wild roses, elderberries, and viburnums, which provide food and shelter for wildlife.

Maintenance and Care

Both shrubs and bushes require regular maintenance to maintain their health and appearance. This includes pruning to remove dead or diseased branches, shape the plants, and encourage new growth. Fertilization and watering are also important, especially during the growing season. By providing proper care, you can ensure that your shrubs and bushes thrive and enhance your landscape for years to come.

Growing Tree Hydrangeas: A Comprehensive Guide

by Zuzana
written by Zuzana

Growing Tree Hydrangeas (Panicle Hydrangeas)

Characteristics and Cultivation

Tree hydrangeas, also known as panicle hydrangeas (Hydrangea paniculata), are fast-growing flowering shrubs with an upright growth habit. They produce showy cone-shaped flower panicles in late summer when few other shrubs are in bloom. These panicles can reach up to 7 inches in length and feature clusters of small, creamy white blooms that gradually turn pinkish and eventually fade to tan or brown in the fall.

Tree hydrangeas are relatively easy to grow and can thrive in a variety of conditions. They are tolerant of pollution, salt, and urban environments. They prefer moist but well-drained soil with an acidic to neutral pH. These shrubs require full to partial sunlight, with some afternoon shade in hot climates.

Planting and Care

The best time to plant tree hydrangeas is in the spring or early fall. Choose a planting site with good drainage and protect the plants from strong winds, which can damage their stems.

Water tree hydrangeas regularly, especially during hot and dry weather. Avoid overwatering, as this can lead to root rot and other diseases. Fertilize the shrubs twice a year, once in early spring and again in the fall after the flowers have faded. Use a fertilizer formulated for shrubs and trees.

Pruning and Training

Tree hydrangeas can be trained to grow as small trees by judicious pruning. However, they achieve their best form when grown as large shrubs with multiple stems. Blooms occur on the current season’s growth, so prune as needed in the late winter to early spring. Untimely pruning can sacrifice some of the flowers for that growing season.

To train a tree hydrangea to grow as a tree, choose one main stem and secure it to a sturdy stake. Remove any competing ground stems and shoots that emerge from the main stem. Continuously check for shoots around the base of the plant and remove them as they appear. The main stem will eventually form a trunk-like structure.

Propagation

Tree hydrangeas can be propagated by cuttings. The best time to do this is in the spring or early summer before the plant begins to flower. Choose a healthy stem that has not yet flowered and cut off a piece that’s about 6 inches long. Remove the lower leaves and cut the remaining leaves in half. Dip the cutting in rooting hormone and plant it in a small container filled with vermiculite, coarse sand, or a combination of the two. Keep the soil moist but not soggy and place the container in a bright but indirect light. The cutting should develop a root system within a month.

Overwintering

To help tree hydrangeas through the winter, keep the soil moist right up until the ground freezes. Cover the roots with 3 to 4 inches of mulch, taking care to remove it as soon as the temperatures warm up.

Pests and Diseases

Tree hydrangeas are generally resistant to pests and diseases. However, they can be susceptible to aphids, rose chafers, scale, slugs, and snails. Organic pesticides can be used to control these pests. Fungal diseases such as powdery mildew, blight, and leaf spot can also affect tree hydrangeas. These diseases can be treated with an appropriate fungicide.

Troubleshooting

Leaves Turning Black/Brown: This can be a sign of a fungal disease. Prune off the affected area or use a suitable fungicide.

Leaves Turning Yellow: This can indicate overwatering, underwatering, or a nutrient deficiency. Adjust watering practices and fertilize as needed.

FAQs

What is the difference between tree hydrangeas and hydrangea bushes?

Tree hydrangeas are shrubs that have an upright growth habit and can be trained into a tree-like form. Hydrangea bushes are typically shorter and more compact.

Can tree hydrangeas grow indoors?

Tree hydrangeas can be grown as container plants indoors, but they may not reach their full potential in terms of size and flowering.

How should I prune my tree hydrangea to encourage flowering?

Prune tree hydrangeas in the late winter to early spring, removing any dead or damaged stems. Cut back the remaining stems to about 6 inches above the ground. This will encourage the growth of new stems that will produce flowers in the summer.

Red Twig Dogwood: A Guide to Planting, Care, and Winter Interest

Planting and Growing Conditions

Red twig dogwood (Cornus spp.) is a hardy shrub known for its brilliant red stems that add a splash of color to the winter landscape. These versatile shrubs thrive in a variety of conditions, including:

  • Sun Exposure: Full sun to partial shade
  • Soil: Moist, well-draining soil
  • Soil pH: Acidic (pH 5.5-6.6)
  • Hardiness Zones: 3-8 (USDA)

Planting Tips:

  • Choose a planting site with ample sunlight for optimal stem color.
  • Dig a hole twice as wide and slightly deeper than the root ball.
  • Plant the shrub so that the root ball is level with the soil surface.
  • Water deeply after planting.

Care and Maintenance

Red twig dogwood is a relatively low-maintenance shrub that requires minimal care:

  • Watering: Water newly planted shrubs weekly, especially during dry spells. Mature plants only need watering during extended periods of drought.
  • Fertilizing: Fertilize lightly in early spring with compost or fish emulsion.
  • Pruning: Prune annually or every few years to remove older branches and encourage new growth. This will maintain the vibrancy of the red stems.

Troubleshooting Common Issues

  • No Red Color: Older stems may lose their vibrancy. Prune back to healthy wood to promote new growth with brighter stems.
  • Black Spots on Stems: Stem blight causes brownish-black patches. Prune out affected stems using sanitized tools.
  • Developing Suckers: Suckers can sap energy from the shrub, resulting in less colorful stems. Remove them with sharp, disinfected garden shears.

Landscaping Benefits

Red twig dogwood offers numerous benefits in the landscape:

  • Winter Interest: The shrub’s bright red stems provide a striking contrast against the snowy winter backdrop.
  • Four-Season Beauty: In spring, the shrub produces clusters of white flowers that give way to white berries in summer. Fall foliage turns shades of rose or gold.
  • Wildlife Habitat: The berries attract birds and small animals.
  • Erosion Control: Red osier dogwood (Cornus sericea) spreads by suckering, forming dense thickets that can help stabilize soil on hillsides.

Propagation

  • Red twig dogwood can be propagated by hardwood cuttings taken in late fall.
  • Cut a stem as thick as a pencil and divide it into 6-9 inch sections with a bud near either end.
  • Remove side branches and dip the cuttings in rooting hormone.
  • Plant the cuttings in pots and place in a sheltered area or cold frame for the winter.
  • Water regularly and keep the soil moist.
  • Once rooted, transplant the saplings to their desired location.

Encouraging Blooms

  • Prune after the shrub has bloomed to avoid removing flower buds.
  • Water deeply during dry spells to promote blooming.
  • Protect young buds from frost by covering the plant during early spring cold snaps.

Additional Tips

  • Choose the right variety for your specific needs. Tatarian dogwood (Cornus alba) and red osier dogwood (Cornus sericea) are common choices.
  • Plant red twig dogwood in groups of three or more for a more dramatic effect.
  • Use the shrub as a hedge or privacy screen.
  • Combine red twig dogwood with other shrubs and plants for a variety of textures and colors in the landscape.

By following these tips, you can enjoy the beauty and benefits of red twig dogwood in your home landscape for years to come.
