If your lavender plants start to decline, you might consider propagation as a way to maintain them in your garden. Lavender can be propagated through various methods:
1. Cuttings
Taking cuttings from healthy plants in late spring or early summer is an effective way to propagate lavender. Here’s how:
- Cut 4-6 inches from the stem below a leaf node.
- Remove the lower leaves to prevent rot.
- Stick the cuttings in a pot with a well-draining soil mix.
- Water lightly and place in a warm area with indirect sunlight.
2. Division
Dividing overgrown lavender plants can rejuvenate the garden and encourage new growth. This should be done in early spring or fall:
- Dig up a mature plant gently to avoid damaging the roots.
- Split the root ball into 2-3 sections.
- Replant immediately, ensuring proper spacing and care.
Signs Your Lavender Needs Replacing
Even with the best care, lavender does not last forever. Here are signs that it may be time to replace your lavender plants:
1. Lack of Blooms
If your lavender is growing well but no longer produces blooms, it may indicate the plant is aging or the growing conditions have changed.
2. Legginess and Weakness
Leggy growth is a sign that your lavender isn’t getting enough light or proper care. In such cases, it might be worth replacing it with a new plant that can thrive in your garden’s conditions.
