Seed Treatment (Pre-Planting Preparation)
-
Soaking: Soaking seeds in warm water for 12–24 hours.
-
Sterilization (Recommended for Better Success): Soak seeds in a diluted hydrogen peroxide solution (1 part peroxide to 10 parts water) for 5 minutes to prevent fungal issues.
Planting Instructions
-
Best Planting Time: Spring or early summer for best germination results.
-
Soil Requirements: Well-draining, slightly acidic soil (pH 5.5–6.5); a mix of peat moss, perlite, and sand works well.
-
Sunlight: Provide bright, indirect light or partial sun.
-
Planting Depth: Do not bury the seeds. Lightly press them onto the soil surface, as they need light to germinate.
-
Spacing: If planting multiple seeds, space them 6–12 inches (15–30 cm) apart.
-
Watering: Keep the soil evenly moist but not soggy. Use a spray bottle to mist the soil to prevent disturbing the seeds.
-
Humidity: Maintain high humidity by covering the seed tray with plastic wrap or a humidity dome.
-
Temperature: Maintain a warm temperature of 70–80°F (21–27°C) for best germination.
-
Germination Time: 4–8 weeks, though some seeds may take longer.
Care After Germination
-
Remove the plastic cover once seedlings emerge.
-
Transplant seedlings into larger pots when they have at least two sets of true leaves.
-
Harden off plants gradually before moving outdoors by exposing them to outside conditions over 7–10 days.
-
Keep soil moist but avoid overwatering.
