March is an ideal time for pruning ornamental shrubs as the winter cold recedes and plants begin to awaken. Proper pruning helps shape your garden, promotes healthy growth, and enhances flowering. Understanding the best techniques and timing can make a significant difference in the health and appearance of your shrubs.
Why Prune in March?
Pruning in March takes advantage of the dormant season, allowing cuts to heal quickly and reducing stress on the plants. It also prepares shrubs for the upcoming growing season by encouraging new growth and flowering. Early pruning can prevent disease and improve air circulation within dense foliage.
Tools You Need

Pruning Tips for Ornamental Shrubs
1. Understand Your Shrub
Different shrubs have unique pruning needs. Research the specific species to know when and how to prune for optimal health and flowering. For example, spring-flowering shrubs should be pruned after they bloom, while summer-flowering ones are best pruned in early spring.
2. Remove Dead or Diseased Wood
Start by cutting out any dead, damaged, or diseased branches. Use clean, sharp tools to make precise cuts just above a healthy bud or branch. This encourages healthy growth and prevents disease spread.
3. Shape Your Shrubs
Decide on the desired shape—whether formal or natural—and prune accordingly. Remove crossing branches and thin out dense areas to improve light and air penetration. Maintain a balanced, attractive form.
4. Prune for Size Control
If your shrubs are overgrown, selectively cut back some branches to control size. Avoid cutting too much at once; instead, prune gradually over several seasons to prevent stress.
Additional Tips
- Use clean tools to prevent disease transmission.
- Make cuts at a 45-degree angle just above a bud or lateral branch.
- Avoid pruning during periods of active growth to minimize stress.
- Apply mulch around the base of shrubs to retain moisture and suppress weeds.
Proper pruning in March can rejuvenate your ornamental shrubs and set the stage for a vibrant growing season. With patience and the right techniques, your garden will flourish with healthy, beautiful plants.
