Propagating by Stem Cuttings
The best time to take stem cuttings is during the summer months when the plant is actively growing. Take a cutting about four to six inches long and cut it just below a node. Remove the lower leaves, leaving only a few pairs of leaves at the top of the cutting. Sink the cutting into a small pot filled with well-draining soil and keep it watered. Keep the soil moist but not waterlogged. Place the pot in a warm, bright area, but avoid direct sunlight as it may burn the cutting.
Propagating by Seed
Ocimum calycosum Hochst. can be propagated by seed. It is best to start seeds indoors eight to ten weeks before the last frost date in your area. Sow the seeds in a well-draining soil mix in small pots. Cover the seeds with a thin layer of soil and keep it moist. Place the pots in a warm, bright area and keep the soil moist. The seeds will germinate within a week or two.
Propagating by Division
Ocimum calycosum Hochst. can also be propagated by division. To divide the plant, gently lift it out of the ground and separate the root ball into two or more sections. Replant each section in a well-draining soil mix and keep it watered. Place the plants in a warm, bright area and avoid direct sunlight. Water the plants regularly, keeping the soil moist but not waterlogged.
In conclusion, Ocimum calycosum Hochst. is a plant that is easy to propagate. It can be propagated by stem cuttings, seed, or division.
