Propagation by Seeds
Collect ripe fruits of Eriocoelum Kerstingii Gilg ex Engl. and soak them in water for 24 hours. After soaking, remove the pulp and wash the seeds thoroughly. Sow the cleaned seeds in seedbeds or containers filled with a well-draining potting mixture. Cover the seeds with a thin layer of soil and water it gently.
Keep the soil moist and place the container or seedbed in a shaded area until the seeds germinate. Germination will begin between 2-4 weeks, depending on the environmental conditions. Transplant the seedlings into individual pots or directly into the garden, after they have developed a few pairs of true leaves.
Propagation by Stem Cuttings
Select a healthy Eriocoelum Kerstingii Gilg ex Engl. plant, take a 4-6 inch cutting from the tip of a stem, making sure to remove any flowers or buds. Strip the leaves from the lower half of the stem and dip the cut end into a rooting hormone powder.
Prepare a potting mixture comprised of equal parts peat moss, perlite, and sand. Fill a small pot with the mixture and make a hole in the center. Insert the cutting into the hole and gently firm the mixture around the stem. Water the cutting thoroughly and cover it with a plastic bag to maintain humidity.
Place the pot in filtered light and maintain the humidity by misting the cutting daily. After 3-4 weeks, the cutting will develop roots, and the plastic bag can be removed. Continue to grow the plant until it develops a strong root system and a few pairs of leaves. The new plant can then be transplanted into a larger container or directly into the garden.
