When to Prune Candy Corn Spirea

Tools for Pruning
To prune candy corn spirea, you will need the following tools:
- Pruning shears
- Hand pruners

Pruning Techniques
1. Remove Dead or Diseased Wood
Begin by removing any dead, diseased, or damaged branches. These branches can harbor pests or diseases and should be removed to prevent their spread. Cut these branches back to the main stem or ground level.
2. Thin Out Overcrowded Branches
Overcrowded branches can reduce airflow and sunlight penetration, leading to poor growth and disease susceptibility. Thin out overcrowded branches by removing weaker or crossing branches.
3. Shape the Shrub
Candy corn spirea can be pruned into various shapes, including rounded, oval, or columnar. Use pruning shears to trim branches to the desired shape.
4. Remove Old Wood
Over time, candy corn spirea can develop old, woody stems that produce fewer flowers and leaves. Remove these old stems by cutting them back to the base of the shrub.
5. Rejuvenate the Shrub
If candy corn spirea becomes overgrown or neglected, it can be rejuvenated through severe pruning. Cut back all branches to within 6-12 inches of the ground. The shrub will send out new shoots and regrow vigorously.
