How to grow Roseform Mix Begonia seeds

Choose Your Planting Method

• Well-draining potting mix
• Clear plastic wrap or a humidity dome
• Optional: seedling heat mat

Sowing the Seeds

• Scatter the dust-like seeds on the surface of moist, fine seed-starting mix — do not cover, they need light to germinate
• Press very gently and mist lightly

Provide the Right Conditions

• Light: Bright, indirect light; seeds need light to germinate
• Temperature: 75-78°F (23-25°C)

Germination

• Expect germination in 7-14 days under warm, humid conditions
• Seedlings grow slowly — keep them warm and bright

Transplanting

• Transplant into individual pots when seedlings are about 2 inches tall
• Move outdoors only after all frost danger has passed
• Space plants 8-10 inches apart

Care Tips

• Sun: Partial shade to shade; protect from hot afternoon sun
• Water: Keep soil evenly moist; avoid wetting the foliage
• Fertilizer: Feed regularly with a balanced liquid fertilizer for continuous bloom
• In fall, tubers can be lifted and stored over winter in cool, dry conditions
