How to Propagate Lyall's mariposa lily plant?
1
Begin by acquiring high-quality Calochortus lyallii seeds. Soak the seeds in warm water for 24 hours to enhance germination rates. Ensure seeds are healthy and free of disease.
2
Fill the seed tray with the fine potting mix. Space the seeds evenly, covering them lightly with more potting mix. Maintain soil moisture by misting with water.
3

How to Repot Lyall's mariposa lily plant?
1
Repot your Calochortus lyallii when you see its roots peeking out of the drainage holes or when the soil ceases to drain well. These are tell-tale signs that the plant is outgrowing its current home and needs more space to thrive.
2
Select a pot that is only one size larger than the current one and has excellent drainage holes. The size ensures that the plant doesn't expend too much energy on root growth, and good drainage prevents waterlogging, thus keeping the roots healthy.
3
Opt for a well-draining sandy soil mix rich in organic matter. This type of soil mimics the natural habitat of Calochortus lyallii, providing necessary nutrients while ensuring that water doesn't stagnate around the roots.
