Pruning woody lavender is an essential practice for maintaining the health and beauty of these fragrant shrubs. Over time, lavender plants can become leggy and woody, reducing their flowering potential and aesthetic appeal. By following proper pruning techniques, you can rejuvenate your lavender plants, promote bushier growth, and ensure a bountiful harvest of aromatic blooms.
When to Prune Woody Lavender
The ideal time to prune woody lavender is in early spring, just before new growth begins. This allows the plant to recover from pruning and produce vigorous new shoots. Avoid pruning in the fall or winter, as this can expose the plant to cold damage.
Tools for Pruning
For pruning woody lavender, you will need the following tools:
- Sharp pruning shears
- Bypass pruners (preferred)
- Sterilized pruning saw (for larger branches)
Pruning Techniques
Deadheading
Deadheading involves removing spent flower spikes to encourage new growth and prevent seed formation. Cut back the flower spikes to the first set of healthy leaves below the spent bloom.
Tip Pruning
Tip pruning is a light pruning technique that involves removing the tips of branches by approximately 1/3 to 1/2 their length. This promotes bushier growth and encourages the development of new flower buds.
Renewal Pruning
Renewal pruning is a more drastic form of pruning that involves cutting back woody branches to ground level. This is best done on older plants that have become overgrown or unproductive. Renewal pruning rejuvenates the plant and stimulates new growth.
Rejuvenation Pruning
Rejuvenation pruning is a technique used to restore severely overgrown or neglected lavender plants. It involves cutting back all branches to within 6-8 inches of the ground. This drastic pruning encourages the plant to regenerate and produce new shoots.
Shaping
Shaping is a pruning technique used to give lavender plants a desired shape or size. This can involve removing branches that are out of shape or trimming back overgrown areas.
Thinning
Thinning involves removing select branches to improve air circulation and light penetration within the plant. This helps prevent disease and promotes healthy growth.
Aftercare
After pruning, it is important to provide your lavender plants with proper aftercare to ensure their recovery and continued health.
- Water the plants deeply after pruning to encourage new growth.
- Apply a balanced fertilizer to promote healthy soil and plant development.
- Mulch around the plants to retain moisture and suppress weeds.
- Monitor the plants for signs of disease or pests and address any issues promptly.
