Seed Treatment:
Cold Stratification: Place seeds in a sealed plastic bag with a slightly damp paper towel and refrigerate for 2–4 weeks.
If seedlings emerge during stratification, remove them immediately and plant in moist soil.
Best Time to Sow:
Late summer to early fall (outdoors) or late winter to early spring (indoors).
Optimum Temperature (Day/Night):
60–65°F (16–18°C) — keep temperature steady for best results.
Germination Time: 14-42 days AFTER stratification
Sowing Instructions:
- Use a fine, well-draining seed-starting mix.
- Sow on the surface and press gently — do not cover heavily; a light dusting of vermiculite is optional.
- Mist to moisten the surface. Keep consistently damp but not soggy.
- Cover with a humidity dome or plastic wrap.
- Place in darkness until germination begins (you can use newspaper or cardboard to block light).
Light Requirements (After Germination):
Transfer to bright, indirect light after sprouts appear. Avoid intense direct sunlight during early stages.
Watering Tips:
Water gently from below or use a fine mister to prevent displacing seeds. Avoid overwatering.
Post-Germination Care:
- Transplant or thin seedlings once they have at least 2–3 true leaves.
- Harden off for 7–10 days before moving outdoors.
Transplanting Outdoors:
Plant after frost danger passes. Space 6–8 in (15–20 cm) apart in rich, well-drained soil.
