The Art of Cultivating and Nurturing Shrubs

The Expanding World of Shrubs

The diversity of shrubs available to gardeners has expanded significantly, with hybrids offering a myriad of colors, blooming seasons, and growth habits suitable for various landscapes. Shrubs can thrive in regions where grass struggles, and their dense growth can provide effective screening. They are valued for their ability to:

• Mark property boundaries
• Soften architectural lines
• Provide a backdrop for flower beds
• Conceal unattractive views
• Add structure to garden design
• Attract wildlife with their berries

Optimal Planting Strategies

Planting shrubs is similar to planting trees, with early spring being the ideal time for most regions due to the extended period of favorable growing conditions. However, in milder climates, the planting season can extend through winter. Specific guidelines for New England suggest planting evergreens in September and May, while deciduous shrubs are best planted in October and May.

Key Planting Considerations:

• Moisture Preservation: To prevent the primary cause of planting failures, which is dry roots, gardeners should employ techniques such as balling and burlapping or heeling in.
• Post-Planting Care: Upon receiving shrubs from a nursery, it's crucial to water them immediately, provide initial shade, apply mulch, and prune them back significantly.
• Size and Maturity: Opting for smaller, less expensive shrubs can be advantageous as older plants require more severe pruning, which can delay their establishment.

Watering and Winter Care

Ensuring adequate hydration in the fall, before the ground freezes, is particularly important for shrubs like boxwood, azalea, rhododendron, mountain laurel, and broadleaf evergreens. These plants can lose moisture through their leaves during winter, making them vulnerable to damage.

Pruning for Health and Vitality

Pruning is a critical aspect of shrub care, promoting youthful vigor and preventing overgrowth. Instead of uniformly trimming branches, it's better to selectively remove older ones, even if they appear healthy. For example, with lilacs, using a keyhole saw to cut the oldest stems as close to the ground as possible is recommended.

Pruning Frequency:

• Annual Pruning: Some shrubs, such as deutzias, hydrangeas, buddleia, spireas, and privets, require yearly pruning to remove dead branches caused by winterkill.
• Post-Blooming Pruning: Shrubs like rhododendron, azaleas, magnolia, and buddleia benefit from having spent flower heads removed after the blooming period.

Interesting Shrub Statistics

While the general care of shrubs is well-documented, there are intriguing statistics that often go unnoticed. For instance, according to the National Gardening Association, landscaping with shrubs can increase property values by up to 20%. Additionally, a study by the American Society for Horticultural Science found that well-maintained shrubs can reduce home heating and cooling costs by acting as natural insulation.

In conclusion, the proper planting and maintenance of shrubs can greatly enhance the aesthetic and functional aspects of a garden. By selecting the right varieties, providing appropriate care, and understanding the nuances of pruning, gardeners can ensure that their shrubs remain a vibrant and enduring part of their outdoor spaces.
