Growth Stages

1

Tuber Sprouting

2-3 weeks

Dormant tubers begin sprouting new growth with small shoots emerging from the soil surface.

Plant in spring after last frost. Keep soil warm (65-70°F) and consistently moist. Provide bright, indirect light once shoots appear.

2

Vegetative Growth

4-6 weeks

Stems elongate and spread, developing leaves along trailing branches. Plant fills out and cascades over container edges.

Maintain consistent moisture and humidity (40-60%). Feed weekly with diluted balanced liquid fertilizer. Pinch tips early to encourage branching.

3

Bud Formation

2-3 weeks

Flower buds appear at stem tips and along branches, developing in clusters.

Switch to a higher phosphorus fertilizer to promote flowering. Maintain humidity and consistent watering. Ensure adequate bright, indirect light.

4

Flowering

3-4 months (or until frost)

Large, showy double or semi-double flowers bloom in shades of pink, red, orange, yellow, or white. Blooms appear continuously for months.

Deadhead spent flowers to encourage continuous blooming. Maintain moisture and humidity. Provide consistent bright, indirect light. Fertilize every 2 weeks.

5

Dormancy/Winter

3-4 months

As temperatures cool and daylight decreases, flowering slows and foliage may decline. Tubers enter dormancy.

In zones 10-11, reduce watering and allow some stem die-back. In colder zones, bring plants indoors before first frost or allow to dry out for tuber storage in cool place. Store dormant tubers in peat moss at 45-50°F.

Fun Facts

  • 🌱 Trailing Begonia Cascade is a hybrid derived from Begonia tuberhybrida, bred specifically for its cascading growth habit and abundant double flowers that can reach 2-3 inches in diameter.
  • 🌱 Unlike fibrous begonias, Trailing Begonia Cascade grows from tubers that go dormant in winter, allowing them to be stored dry and replanted the following spring, making them economical for gardeners in cold climates.
  • 🌱 The name 'Cascade' references the plant's natural trailing and waterfall-like appearance when in full bloom, with hundreds of colorful flowers cascading over the edges of containers.
