GROWING INSTRUCTIONS
SEED PRETREATMENT: Soak seeds for 24 hours, start with boiling water. Repeat if needed for seeds to sink.
TIMING: Start seeds indoors 4-6 weeks before final Spring frost date. Harden off seedlings before moving them outdoors.
GERMINATION: 30-60 days. Alternating the soil temperature during the day (25-30°C) and night (20-25°C) will aid germination. Keep soil moist.
SEEDING: Sow seeds 1/4” deep.
