Propagation of Dasystachys grantii Benth. var. engleri Baker

Dasystachys grantii Benth. var. engleri Baker, commonly known as Engler's Dasystachys, can be propagated through different methods including seed propagation, stem cuttings, and division.

Seed Propagation

Propagation of Dasystachys grantii Benth. var. engleri Baker from seeds involves collecting fresh seeds from the plant when they are mature, during the autumn season. The seed pods are picked and dried until they open to reveal the seeds. These seeds are sown in a well-drained mix of compost and sand in a container, and then watered thoroughly. The container is then placed in a greenhouse or a warm shaded place with a temperature range of 20–25 °C. The seeds will germinate in about two weeks and can then be transplanted into separate pots once they are about an inch tall.

Stem Cuttings

Dasystachys grantii Benth. var. engleri Baker can also be propagated through stem cuttings taken from a healthy plant. The stem cuttings should be taken during the summer season when the plant is actively growing. Choose a healthy stem and snip it just below a leaf node, then make a cutting about 4-6 inches long. Remove any leaves from the bottom half of the cutting, and dip the base in rooting hormone. Then, insert the cutting into a mix of sand and peat in a container and water it well. Cover the container with a clear plastic bag to maintain high humidity, and place it in a warm, bright place. The cutting should root in about four weeks and can then be transplanted.

Division

Division is another propagation method that can be used for Dasystachys grantii Benth. var. engleri Baker. It involves dividing the clumps of the plant into smaller sections and replanting them in different containers or locations. This method should be done in the autumn or early spring when the plant is not actively growing. Dig up the clumps carefully, separate them into smaller sections using a sharp knife, and replant them immediately in well-draining soil. Water them thoroughly and place them in a shaded area until they have established roots.
