Begonia Germination Information

Begonia Seed Germination How to Sow Begonia:

  • Sow seeds indoors at a temperature of 68°-75°
  • No cover needed as light aids in germination
  • Expect the small, dust-like seeds to germinate in 15-20 days
  • For indoors use, sow the seeds at any time
  • For outdoor use, sow wax begonias 12 weeks before planting out and tuberous begonias 12-16 weeks before planting out.
  • When sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed

How to Grow Begonia:
Space:  Space wax begonias 8-10 inches apart in part shade to full sun. Space tuberous begonias 8-10 inches apart in part shade.

Soil: Site in a rich, well-drained soil. Allow the soil to dry out between waterings. Fertilize frequently.

Temperature: They prefer climates with cool summers and high humidity. After the first light frost, lift the tubers, wash them, and store in a cool, dark, dry area until replanting in the spring. For conservatory culture of all begonias: provide 65° nights and 70-80° days

Appearance and Use:

This genus is ubiquitous in bedding plantings, borders, hanging baskets, and as house and conservatory plants. It is divided into three groups: fibrous rooted, rhizomatous rooted, and tuberous rooted. The well-known wax begonias (B. x semperflorens-cultorum) are fibrous rooted. They grow 6-12 inches tall with green, bronze, or mahogany leaves. The flowers are singles or doubles and in shades of pink, red, or white. Rex begonias, with highly ornamental foliage in rich colors and variegated designs, represent the rhizomatous types. The tuberous begonias form 8 inch, hanging clusters of solid or bicolored, white, yellow, orange, red, or pink flowers
