Native to Brazil, this rare begonia features striking red-tinged undersides and is prized for its ornamental foliage.
Seed Treatment:
• No stratification required, but due to the tiny size of begonia seeds, they benefit from high humidity and warmth during germination.
• Do not soak or scarify. Begonia seeds are dust-like and should not be handled with wet fingers or tools.
When to Sow:
• Indoors only — not suitable for direct outdoor sowing
• Start seeds year-round indoors, ideally in late winter to early spring for best growth period
Light Requirements:
• Requires bright, indirect light
• Avoid direct sun which may scorch tender leaves
Soil Requirements:
• Use a fine, well-draining seed-starting mix with high organic content
• Recommended mix: 1 part peat moss or coco coir, 1 part perlite
• pH range: 5.5–6.5 (slightly acidic)
Sowing Instructions:
• Surface sow — do not cover seeds; light is essential for germination
• Gently mist to settle seeds onto the surface
• Cover tray with clear plastic lid or humidity dome to maintain high humidity
• Maintain temperature around 70–75°F (21–24°C)
• Place under grow lights or near a bright window (no direct sunlight)
• Germination in 14–28 days
Watering:
• Mist regularly to keep the surface consistently moist but not soggy
• Use a fine spray or bottom-watering method to avoid displacing seeds
Spacing & Transplanting:
• Once seedlings have 2–3 true leaves, transplant carefully into small pots
• Space plants 6–8 inches apart if growing in beds or containers
Growing Tips:
• Begonia ferruginea is best suited for indoor growing, greenhouses, or shaded tropical gardens
• Likes humid, warm environments—keep away from drafts
• Avoid overwatering—allow top layer of soil to dry slightly before watering again
• Feed with a diluted liquid fertilizer every 2–4 weeks during active growth
• May take several months to mature, but the foliage alone makes it worth the wait
