- Clean the seeds by removing any debris, and dry them in a cool and dry place to prevent spoilage.
- Sow the seeds in a well-draining soil mixture, and cover them with a thin layer of soil.
- Keep the soil moist, and place the pot in a warm and bright location.
- The seeds should start to germinate in about 3-4 weeks.
- Transplant the seedlings into individual pots once they have developed their second set of leaves.
- Grow the seedlings in a bright, sunny spot, and keep the soil moist. The young plants should be ready for transplanting to their permanent location in about 6 months.
Propagation by division
The division of Nidorella densifolia O.Hoffm. can be done in the following way:
- Select a mature plant with several clumps of stems and roots.
- Carefully dig up the plant, and use a clean and sharp knife to divide the plant into smaller sections. Each section should have several stems and a good amount of roots.
- Plant the sections in individual pots or directly in the ground, in a well-draining soil mixture.
- Keep the soil moist, and place the pots in a warm and bright location until the new plants become established.
- The new plants should be ready for transplanting to their permanent location in about 3-4 months.
Both propagation methods can be used to expand your Nidorella densifolia O.Hoffm. collection or share it with other gardeners.
