Growing Tips
- Start seeds indoors well before the outdoor growing season because lisianthus develops slowly during its early stages.
- Press seeds gently onto moist growing medium rather than burying them deeply, and provide light during germination.
- Keep the growing medium evenly moist but never soggy to support healthy seedlings.
- Harden seedlings gradually before transplanting outdoors once conditions are suitable and the danger of frost has passed.
Seed Storage
Store unused seeds in a cool, dry, and dark location. Keep them in a sealed, moisture-resistant container away from heat and humidity. Avoid storing seeds in areas with frequent temperature changes.
