Dormancy/Sprouting
2-4 weeksTubers are at rest or just beginning to sprout small shoots and roots. Tubers appear dry and inactive.
Start tubers indoors in late winter (February-March) in moist peat. Keep at 65-70°F. Do not water heavily until shoots emerge.
Vegetative Growth
3-4 weeksYoung plants develop trailing stems with heart-shaped green foliage. Growth is rapid and cascading begins.
Maintain bright, indirect light and warm temperatures (65-75°F). Keep soil consistently moist. Pinch stem tips early to encourage branching and fuller cascades.
Budding
2-3 weeksFlower buds appear at leaf nodes along trailing stems. Buds are small, tight, and developing color.
Maintain humidity at 50-70% to prevent bud drop. Continue consistent watering and bright light. Avoid cold drafts and temperature fluctuations.
Flowering
6-8 weeks (peak blooming)Ruffled, double or semi-double flowers open in shades of red, pink, orange, yellow, or white. Flowers may reach 2-3 inches across. Multiple blooms open continuously along stems.
Deadhead spent flowers to encourage continuous blooming. Maintain consistent moisture and humidity. Avoid overhead watering. Provide afternoon shade in hot climates.
Decline/Dormancy
4-8 weeksFlowering slows as temperatures cool in fall. Foliage may yellow. Tubers begin storing energy for next season.
Reduce watering gradually. Allow foliage to die back naturally. Stop fertilizing. Once foliage is completely dry, lift tubers, clean, and store in cool (50-60°F), dry location for winter.

Harvest Tips
Trailing Begonia Bertini is grown for ornamental flowers, not harvest. Deadhead spent blooms by pinching behind the flower to encourage continuous blooming throughout the season. For tuber preservation: In fall after the first frost or when foliage yellows, cut stems back to 2 inches. Lift tubers carefully, rinse gently, and allow to dry in a cool location for 1-2 weeks. Store tubers in dry peat moss or vermiculite at 50-60°F until spring.
