Propagation by Seeds
Propagating Grumilea gossweileri Cavaco from seeds is a viable option. Collect the seeds from the fruit which develops after the flowers. Clean the seeds thoroughly, removing any flesh or debris still attached to them.
Sow the seeds in a well-draining soil mix, covering them with a light layer of soil. Keep the soil moist and in a warm area with filtered or indirect sunlight. Germination may take up to several weeks.
Once the seedlings have established, transplant them into individual pots with a rich, well-draining soil mix. Regularly fertilize and monitor the moisture levels to promote growth.
Propagation by Cuttings
Another method of propagation is through stem cuttings. Take a 6-8 inch cutting from a healthy Grumilea gossweileri Cavaco plant, making a diagonal cut at the base of the stem.
Remove any leaves from the lower half of the stem, then dip the cut end in rooting hormone. Insert the cutting in a pot with a moistened soil mix, taking care not to press the soil too tightly around the stem. Place the cutting in indirect sunlight and keep the soil moist until roots have formed.
Once the cutting has established a root system, transplant it into a well-draining soil mix. Maintain the plant with regular watering and fertilization.
Conclusion
Grumilea gossweileri Cavaco is a rare and unique plant species that can be propagated by either seeds or stem cuttings. With the proper care and attention, these propagation methods can result in healthy and thriving new plants.
