Propagation of Lycopus diantherus Buch.-Ham. ex Roxb.
Lycopus diantherus Buch.-Ham. ex Roxb. or commonly known as Gypsywort, is a perennial herbaceous plant that is propagated primarily through seeds and vegetative propagation. It is a rhizomatous plant that grows up to 1 meter tall and is endemic in the Himalayas, Southern China, Bhutan, and Northern India.
Propagation Methods
1. Seeds propagation: One of the easiest and most commonly used methods is to propagate Lycopus diantherus through seeds. Collect the seeds from the matured plant, which turn brown when ripe, and store them in a cool and dry place until they are ready to be sown. Sow the seeds in seed trays or pots and cover them with a thin layer of soil. Keep the soil moist and warm until germination, which usually takes 2 to 3 weeks.
2. Vegetative propagation: Lycopus diantherus can also be propagated through vegetative propagation methods like root divisions and stem cuttings. Rhizome or root division can be done in spring or autumn by digging up the plant and dividing the roots or rhizome into separate sections, ensuring that each section has at least one growing point. Plant the divided sections in pots or directly in the ground and keep them moist until they establish.
3. Stem cutting propagation: Another viable method is stem cutting propagation. Take cuttings of healthy stems in spring or summer and remove the lower leaves, leaving only the uppermost 2-4 leaves on the stem. Dip the cut end of the stem into rooting hormone, and plant it into a pot or tray. Keep the soil moist, and once the stem develops roots, transplant it into a larger pot or directly into the ground.
Lycopus diantherus is a valuable medicinal herb, and propagating it is relatively easy through seeds or vegetative propagation. With proper care, it can thrive in various growing conditions.
