Once the seeds are completely dry, they can be planted in pots filled with well-draining soil mix. Keep the soil moist and warm, and the seeds will germinate within 2-3 weeks.
Propagation by Cuttings
Propagation by cuttings is another effective way of propagating Aspilia dewevrei O. Hoffm. This method involves taking a stem cutting from an existing plant and planting it in soil or water until it roots. The best time to take the cuttings is in the rainy season, from May to October.
To propagate by cuttings:
- Take a 10-15 cm long stem cutting from a healthy Aspilia dewevrei O. Hoffm. plant.
- Remove the lower leaves and plant the cutting in a pot filled with well-draining soil mix.
- Water the soil and place the pot in a warm and humid place, away from direct sunlight.
- Within a few weeks, the cutting will develop roots and can be transplanted to a larger pot or directly into the ground.
Aspilia dewevrei O. Hoffm. is a low maintenance plant that can thrive in a wide range of soil types, as long as the soil is well-draining. The plant requires regular watering, especially during the dry season, and fertilizer application to encourage healthy growth.
