Begonia tuberhybrida | Tuberous Begonia (PELLETED)

Seed Type: Pelleted (fine seeds coated for easier handling)
Do Not Soak: Pellets are water-soluble — soaking can damage the seeds.

Optimum Temperature:
75–78°F (23–25°C) for best germination
• Use a heat mat if needed to maintain consistent warmth

Moisture & Humidity:
• Keep surface evenly moist — mist gently to dissolve the coating
Humidity above 95% is essential for strong germination
• Use a dome or cover to maintain humidity levels

pH & Growing Medium:
• Use sterile, fine seed-starting mix
• Maintain media pH between 5.5 and 6.5

Light Requirements:
Needs light to germinate — do not cover with soil
• Provide bright indirect light or grow lights (14–16 hours/day)
• Supplemental 24-hour light at germination stage boosts germination, reduces crop time, and improves seedling quality

Germination Time:
14–21 days under optimal conditions
• Up to 45 days under sub-optimal conditions

Post-Germination Care:
• Remove dome once seedlings appear
• Begin air circulation to prevent damping off
• Thin seedlings after true leaves develop
• Water gently — avoid splashing delicate roots

Transplanting:
• Transplant when seedlings have 2–3 sets of true leaves
• Harden off gradually before moving outdoors

Sowing Schedule:
• Start indoors 10–12 weeks before last frost
