How to Start Both Series from Seed: Key Tips
- Surface sow — never bury seeds. Both Hethor and Paradiso need light to germinate. Press seeds gently onto moist seed-starting mix and do not cover.
- Keep it cool: 55–65°F (13–18°C). This is the single most important factor. Warm conditions will dramatically reduce germination rates.
- Optional cold stratification: Refrigerate sown trays for 1–2 weeks before moving to germination conditions. This can improve germination rates, especially for Paradiso Double varieties.
- Expect 14–28 days to germinate for Hethor; Paradiso Double may take up to 6 weeks. Be patient.
- Grow on under lights at 55–65°F with 14–16 hours of light per day for compact, strong seedlings.
- Transplant after last frost once seedlings are well established and hardened off.
