Seed Treatment
- Cold Stratification: Place seeds in a moist paper towel inside a sealed plastic bag and refrigerate for 2-4 weeks.
- Scarification: Lightly rub seeds with sandpaper or soak them in warm water for 12-24 hours before planting to soften the seed coat.
Planting Instructions
- Timing:
- Start seeds indoors 6-8 weeks before the last frost for early blooms.
- Direct sow in early spring or late fall for natural cold stratification.
- Soil:
- Prefers well-draining, fertile soil with a pH of 6.0-7.5.
- Can tolerate poor soils but thrives in nutrient-rich conditions.
- Light:
- Full sun (at least 6-8 hours per day) is best for strong growth and flowering.
- Sowing:
- Surface sow seeds and lightly press them into the soil.
- Do not bury deeply, as seeds need light to germinate.
- Watering:
- Keep soil evenly moist but not waterlogged until germination occurs (usually 10-20 days).
- Once established, Ammi visnaga is drought-tolerant and requires minimal watering.
- Temperature:
- Optimal germination temperature is 65-75°F (18-24°C).
- Spacing:
- Thin seedlings to 12-18 inches apart for proper air circulation and healthy growth.
Once mature, Ammi visnaga produces stunning white, umbel-shaped flowers that attract pollinators and make excellent cut flowers or dried floral arrangements! ?✨
