When to Prune Candy Corn Spirea
The best time to prune candy corn spirea is in late winter or early spring, before new growth begins. Pruning during this time allows you to remove dead or damaged branches and shape the plant while minimizing stress.
Step-by-Step Pruning Instructions
1. Remove Dead or Damaged Branches
Begin by removing any dead, diseased, or broken branches. Cut them back to the point where they join a healthy stem or branch.
2. Prune for Shape and Size
Candy corn spirea can be pruned to maintain a desired shape or size. To reduce the overall size, cut back branches by one-third to one-half their length. To shape the plant, selectively remove branches that are growing out of bounds or disrupting the desired form.
3. Thinning the Canopy
Over time, candy corn spirea can become dense and overgrown. To improve air circulation and sunlight penetration, thin the canopy by removing some of the older, inner branches. This will promote new growth and prevent the plant from becoming leggy.
4. Rejuvenation Pruning
If your candy corn spirea has become overgrown or neglected, rejuvenation pruning may be necessary. This involves cutting back the plant to within a few inches of the ground in late winter or early spring. New shoots will emerge from the base, creating a revitalized and more manageable plant.
Tips for Pruning Candy Corn Spirea
- Use sharp, clean tools to prevent disease transmission.
- Make clean cuts at an angle to promote water drainage.
- Avoid pruning during hot, dry weather.
- Feed your candy corn spirea after pruning to encourage new growth.
- Mulch around the base of the plant to retain moisture and suppress weeds.
Pruning to Encourage Flowering
Candy corn spirea blooms on new growth. By pruning in late winter or early spring, you remove old flower stalks and encourage the development of new flowering shoots. To maximize flowering, prune back the branches by about one-third to one-half their length.
Pruning for Fall Color
Candy corn spirea is known for its vibrant fall foliage. To enhance the color, prune the plant lightly in late summer after it has finished flowering. Remove any dead or damaged leaves and selectively trim branches to encourage new growth. The new leaves that emerge in the fall will display the most intense colors.
