Growth Stages

1

Tuber Dormancy & Sprouting

2-4 weeks

Tubers are stored dry and begin to sprout when exposed to warmth and moisture. Small shoots emerge from the concave top of the tuber.

Start tubers indoors 4-6 weeks before last frost. Keep soil warm (65-70°F) and lightly moist but not wet. Provide bright, indirect light once shoots appear.

2

Vegetative Growth

3-4 weeks

Young plants develop stems, leaves, and trailing growth. Foliage is lush green with bronze or reddish undertones. No flowers yet.

Pinch back growing tips early to encourage bushier, fuller growth and more branches. Maintain consistent moisture and humidity. Feed with balanced fertilizer every 2 weeks.

3

Flowering Initiation

1-2 weeks

Flower buds begin to form in leaf axils along the trailing stems. Plant is full and dense with vigorous growth.

Switch to a phosphorus-rich fertilizer to promote blooming. Maintain humidity around 50-60%. Continue pinching if needed to shape the plant.

4

Active Flowering

12-16 weeks

Abundant vibrant orange-red flowers bloom profusely along cascading stems. Blooms continue throughout warm months. Plant is at peak ornamental value.

Deadhead spent flowers to encourage continuous blooming. Maintain consistent watering without overwatering. Keep temperatures between 60-75°F for best blooming. Apply low-nitrogen fertilizer weekly.

5

Decline & Dormancy

4-8 weeks

As temperatures cool in fall, flowering slows and foliage may yellow. Plant enters natural dormancy as winter approaches.

Gradually reduce watering as growth slows. Stop fertilizing. Cut back foliage to 2-3 inches above tuber level. Store tubers in cool, dry location (50-60°F) over winter for re-growth next season.

Harvest Tips

Trailing Begonia Bonfire is an ornamental flower, not harvested for produce. Deadhead (remove) spent flowers regularly to encourage continuous blooming throughout the season. Pinch back growing tips occasionally to maintain full, cascading shape. In fall, allow tubers to naturally decline, then harvest and store them dry and cool for replanting next season.

Fun Facts

  • 🌱 Trailing Begonia Bonfire is a hybrid tuberous begonia, meaning it's a cross between different begonia species and develops underground storage tubers that allow it to survive winter dormancy and regrow the next season.
  • 🌱 The name 'Bonfire' perfectly describes this variety's fiery orange-red flowers, which remain vibrant and prolific even in shaded locations where many other flowering plants struggle to produce color.
  • 🌱 Begonias are unique among ornamental plants in that male and female flowers are produced on the same plant (monoecious); the larger flowers you see are typically male, while smaller female flowers develop seed pods.
