Why Thinning Your Shrubs Is Better Than Shearing Them
Why Thinning Your Shrubs Is Better Than Shearing Them
Published by Urban Garden Solutions
It can be tempting to grab the hedge trimmers and give your shrubs a quick once-over to achieve that uniform, boxy look. But while shearing creates a tidy surface, it often does more harm than good in the long run.
At Urban Garden Solutions, we recommend a more strategic approach: selective thinning. This technique removes entire interior branches and creates intentional gaps or "windows" to allow light and air to penetrate the plant's canopy.
The Problem With Surface Shearing
Shearing only cuts the outer layer of foliage, causing:
Dense outer growth that shades the interior
Reduced airflow, leading to increased humidity and pest problems
Weak interior structure due to lack of light and stimulation
Overall plant stress and reduced vigor
The Benefits of Thinning Shrubs
Selective thinning provides a wide range of benefits that support plant health and longevity:
☀️ Better Sunlight Penetration
By opening up the shrub’s interior, light can reach more of the plant, stimulating growth from within rather than just the surface.
💨 Improved Airflow
Thinning allows for better air circulation, reducing the risk of fungal diseases and discouraging pests that thrive in moist, stagnant environments.
🌿 Stronger New Growth
Instead of producing soft, weak outer shoots (common with shearing), the plant develops more balanced and vigorous growth, contributing to its long-term shape and health.
🪲 Pest Reduction
Dense, compact shrubs are a magnet for scale, spider mites, aphids, and fungal issues. Thinning removes overcrowded areas where pests hide and improves spray coverage if treatment is needed.
🌱 A Natural Look
Thinning preserves the plant's natural form, allowing it to grow attractively and sustainably over time.
When to Thin Shrubs
Late winter to early spring is ideal for structural thinning on most shrubs, just before new growth begins. However, some species may benefit from light thinning in summer after flowering.
