How to grow Illumination Mix Tuberous Begonia seeds

Choose Your Planting Method

• Indoors: Start indoors 12-16 weeks before the last frost — begonias are slow from seed.
• Outdoors: Plant out only after all frost danger has passed.

Prepare Your Materials

• Seed-starting trays or pots (if indoors)
• Well-draining potting mix
• Clear plastic wrap or humidity dome
• Spray bottle for misting

Sowing the Seeds

• Surface sow on fine, moist mix — do not cover; begonia seed needs light to germinate.

Provide the Right Conditions

• Light: Bright, indirect light; grow lights help.
• Temperature: 70-75°F (21-24°C).
• Humidity: A humidity dome is important — the dust-like seeds dry out fast.

Germination

• Seeds sprout in 10-21 days.
• Remove the cover once sprouted; grow on cooler at 60-65°F (16-18°C).

Transplanting

• When seedlings are large enough to handle (about 4-5 weeks after germination)
• Harden off 7-10 days in a shady spot
• Space 8-12 inches apart in baskets or beds

Care Tips

• Sun: Partial to full shade — avoid harsh midday sun.
• Water: Keep soil consistently moist but not soggy.
• Fertilizer: Feed every 2-3 weeks with a balanced water-soluble fertilizer.

Bloom Time:

Summer to the first frost.
