Growing lavender from cuttings is a simple and efficient way to expand your garden with this fragrant and beautiful herb.
Lavender is prized for its aromatic flowers and versatile uses, from culinary applications to essential oils and ornamental purposes.
Propagating lavender from cuttings not only saves money but also allows gardeners to clone their favorite varieties, ensuring the new plants carry the same desirable traits.
Here’s a step-by-step guide on how to grow lavender successfully from cuttings.
1. Choose the Right Time
The best time to take lavender cuttings is in late spring to early summer when the plant is actively growing but not yet blooming, or in early fall before the plant goes dormant.
This timing ensures that the cuttings have enough time to root before either the heat of summer or the cold of winter.
2. Select Healthy Parent Plants
Choose a healthy, mature lavender plant as the source of your cuttings.
Look for plants that are vigorous, disease-free, and have the color, scent, and growth habit you desire. This increases the chances of successful propagation.
3. Taking Cuttings
- With a sharp, clean pair of pruning shears or scissors, cut a 3-4 inch piece from the new, soft growth at the top of the plant. Make sure the cutting has at least two sets of leaves.
- Remove the leaves from the bottom half of the cutting to expose the nodes (where the leaves were attached). This is where roots will develop.
4. Prepare the Cuttings
Dip the cut end of each cutting into rooting hormone powder or gel. This step is optional but can increase the success rate of rooting by stimulating root growth and protecting the cutting from rot and disease.
5. Plant the Cuttings
Fill small pots or a tray with a well-draining potting mix or a mixture of perlite and coarse sand. Stick the cut end of the cuttings into the soil, ensuring that the nodes where you removed the leaves are buried. Gently firm the soil around the cuttings.
6. Create a Humid Environment
To maintain humidity around the cuttings, which helps prevent them from drying out before they root, cover the pots or tray with a clear plastic bag or place them in a mini greenhouse.
Be sure the plastic doesn’t touch the cuttings by supporting it with sticks or hoops.
7. Place in Indirect Light
Position the cuttings in a warm spot with indirect light. Avoid direct sunlight, which can overheat and stress the cuttings. A north-facing windowsill or a shaded part of a greenhouse is ideal.
8. Watering and Care
Keep the soil moist but not waterlogged. Too much water can cause the cuttings to rot. Use a spray bottle to mist the soil if it begins to dry out.
Ventilate the cuttings daily by removing the plastic cover for a few hours to reduce the risk of fungal infections.
9. Checking for Roots
After 4-6 weeks, gently tug on the cuttings. A slight resistance indicates that roots have formed. At this point, gradually acclimate the cuttings to the outside environment by removing the plastic cover for longer periods each day.
10. Transplanting
Once the cuttings have developed a robust root system, transplant them into larger pots or directly into the garden.
Choose a sunny location with well-draining soil. Lavender thrives in dry, sandy conditions and does not do well in wet, clay-heavy soils.
11. Aftercare
Water the newly transplanted lavender sparingly, as established plants are drought-tolerant. In the following spring, lightly prune the plants to encourage bushy growth and prevent them from becoming woody.
Growing lavender from cuttings is a rewarding project that can yield beautiful and aromatic results. With patience and care, you can propagate lavender successfully and enjoy this beloved herb in various aspects of your home and garden.
