Tools You’ll Need

- Lopping shears (for larger branches)
- Gloves
Pruning Techniques
1. Remove Dead, Diseased, or Damaged Branches
Begin by inspecting the shrub for any branches that are dead, diseased, or damaged. These branches are often brown, brittle, or have signs of decay. Remove them completely by cutting them back to the main stem or ground level.
2. Thin Out Overcrowded Branches
Candy corn spirea can become overcrowded if not properly pruned. Identify any branches that are rubbing against each other or crossing over. Remove the weaker or less desirable branches to improve air circulation and prevent disease.
3. Shape the Shrub
Once you have removed the dead and overcrowded branches, you can start shaping the shrub. Candy corn spirea can be pruned into a variety of shapes, such as a rounded mound, a hedge, or a tree form. Use sharp pruning shears to carefully trim the branches to your desired shape.
4. Rejuvenate Old Shrubs
If your candy corn spirea has become overgrown or leggy, you may need to rejuvenate it. Cut back the oldest and thickest branches to the ground level. This will encourage new growth and rejuvenate the shrub.
5. Prune for Color
Candy corn spirea’s vibrant foliage is one of its main attractions. To enhance its color, prune the shrub regularly to encourage new growth. New growth produces the most intense foliage color.
6. Avoid Pruning Too Severely
While pruning is important, avoid pruning too severely. Remove only the necessary branches and avoid cutting into live wood. Over-pruning can weaken the shrub and reduce its flowering ability.
Pruning Tips
- Always use sharp tools to make clean cuts.
- Cut branches at a slight angle to prevent water from collecting on the cut surface.
- Clean your pruning tools regularly to prevent the spread of disease.
- If you are not comfortable pruning your candy corn spirea yourself, consult a certified arborist.
