Growth Stages

1

Seedling

2-3 weeks

Tiny seeds germinate into delicate, cotyledon-bearing seedlings with first true leaves emerging.

Keep soil warm (70-75°F) and consistently moist. Provide bright, indirect light. Thin seedlings or transplant to individual containers at 2-3 true leaves.

2

Vegetative Growth

3-4 weeks

Plant develops bushy, compact mounding form with increasingly abundant foliage. Bronze or green leaves expand steadily.

Maintain consistent moisture and warmth. Apply balanced fertilizer every 2-3 weeks. Pinch back growing tips to encourage bushiness if desired.

3

Early Flowering

2-3 weeks

First flower buds appear in leaf axils; small delicate flowers open in red, pink, or white depending on variety.

Ensure adequate light (at least 4 hours daily). Switch to slightly higher phosphorus fertilizer (e.g., 5-10-5) to encourage flowering. Maintain consistent watering.

4

Full Bloom & Continuous Flowering

8-12 weeks until frost or end of season

Plant is completely covered in waxy flowers. Lotto Series exhibits exceptional flower production and color intensity. Bronze foliage contrasts beautifully with blooms.

Deadhead spent flowers to promote continuous blooming (though self-cleaning tendency reduces need). Water consistently and fertilize every 2-3 weeks. Reduce watering slightly if grown indoors.

5

Season End / Dormancy

Variable (frost-dependent)

In cooler climates, frost kills plants. In warm zones, plants may slow growth or be overwintered indoors.

In zones 10-11, reduce watering and fertilizing in winter. In cooler zones, allow plants to be killed by frost or dig up and pot indoors before first frost for overwintering.

Harvest Tips

Wax begonias are primarily grown for ornamental flowers and foliage rather than harvest. Deadhead spent flowers regularly to maintain appearance and encourage continuous blooming. Cut stems can be used in floral arrangements; flowers last several days in water.

Fun Facts

  • 🌱 Wax begonias are called 'wax' because their leaves have a waxy, succulent appearance that protects them from water loss and gives them a distinctive glossy sheen.
  • 🌱 The Lotto Series was specifically bred for exceptional cold and heat tolerance, making it one of the most reliable wax begonia series for variable climates.
  • 🌱 Wax begonias continuously self-clean, meaning they naturally drop spent flowers without deadheading, though regular deadheading enhances appearance and flower production.
