How can a Knautia plant be multiplied?
There are several ways to multiply a Knautia plant, including division, stem cuttings, and seed propagation.
Division:
Division is a simple and effective method of multiplying Knautia plants. It is best done in the spring or fall when the plant is not actively growing. Carefully dig up the plant and gently pull or cut the rootball into smaller sections, making sure each section has at least one strong shoot and several healthy roots. Replant the divisions in well-drained soil, and water them well.
Stem Cuttings:
Another way to multiply Knautia plants is through stem cuttings. This method is best done in the late spring or early summer when the plant is actively growing. Take a 4-6 inches long stem cutting from the tip of a healthy stem, remove the lower leaves, and insert it into a rooting hormone powder. Place the cutting in a well-draining potting mix and keep it in a warm, bright spot out of direct sunlight. Keep the soil moist, but not waterlogged. After a few weeks, roots will begin to form and new growth will appear. Once the cutting has rooted, it can be transplanted into the garden.
Seed Propagation:
Knautia plants can also be propagated from seed. The seeds should be sown in a seed tray or pots filled with seed compost, and placed in a propagator or covered with a plastic bag in a warm place. Keep the compost moist but not waterlogged and germination usually takes 2-3 weeks. Once the seedlings are large enough to handle, transplant them into 7.5cm (3in) pots. Gradually acclimatize them to outdoor conditions for 10-15 days before planting them out in the garden.
In summary, Knautia plants can be multiplied by division, stem cuttings, and seed propagation. Division is a simple and effective method of multiplying Knautia plants, best done in the spring or fall. Stem cuttings can be taken in late spring or early summer and should be treated with rooting hormone powder before planting.
