Step-by-Step Pruning Instructions
Deadheading
- Remove spent flowers by cutting the stem just below the flower head.
- Deadheading encourages the plant to produce more flowers and prevents seed formation.
Thinning
- Select overcrowded stems and remove them at the base of the plant.
- Thinning improves air circulation and allows the remaining stems to grow stronger.
Cutting Back
- Cut back old or overgrown stems to a height of 6-8 inches from the ground.
- Cutting back rejuvenates the plant and promotes new growth.
Shaping
- Use shears to shape the plant into a desired form, such as a mound or a pyramid.
- Shaping enhances the plant’s aesthetic appeal and prevents it from becoming leggy.
Special Considerations for Autumn Pruning
- Avoid pruning in the fall or winter, as it can damage the plant and reduce its cold tolerance.
- If necessary, light pruning can be done in the late fall to remove any dead or damaged foliage.
Troubleshooting Common Pruning Issues
- Leggy Plants: If the stems are too long and thin, cut them back more severely to encourage bushier growth.
- Lack of Flowers: Insufficient pruning can lead to a reduction in flowering. Prune more frequently to stimulate new growth and flower production.
- Disease or Pests: Pruning removes infected or damaged foliage, helping to prevent the spread of disease and deter pests.
