FAQs

When is the best time to plant the begonia tubers?

Start tubers off indoors from February in a warm, frost-free location. Plant them outdoors after all risk of frost has passed, following a period of acclimatization.

What kind of soil do these begonias prefer?

They prefer well-drained, moist compost. Ensure good drainage, especially when planting in containers.

Can I leave the tubers in the ground over winter?

No, these are half-hardy tubers. They should be lifted and stored in a dry, frost-free place over winter or treated as annuals.

How much sun do they need?

They can grow in full sun, sun, or semi-shade, but prefer locations protected from strong winds. Optimal performance is often seen in sun to partial shade.

What is the mature size of the plants?

When fully established, the plants typically reach up to 30cm (11.8 inches) in height and spread.

How often should I water them?

Keep the soil consistently moist, but avoid waterlogging. Water when the top inch of soil feels dry.

What does 'half-hardy' mean for these tubers?

Half-hardy means they cannot tolerate frost. They need to be protected from cold temperatures during their initial growth phase and overwintering.

Troubleshooting

Tubers not sprouting

Ensure they are planted with the indented side up and are in a warm, sufficiently lit environment. Check that the compost is kept consistently moist.

Yellowing leaves

This can indicate overwatering or poor drainage. Allow the soil to dry slightly between waterings and ensure the pot or bed has adequate drainage.

Lack of blooms

Ensure the plant is receiving adequate sunlight (or appropriate semi-shade) and nutrients. Consistent watering and occasional feeding can help promote flowering.

Pests (e.g., slugs, snails)

Use appropriate slug and snail deterrents. Handpick pests when visible, especially in the early morning or evening.

Setup, Compatibility & Care

Starting Indoors (February onwards):

  1. Use well-drained, moist compost.
  2. Place tubers in a warm, frost-free position with bright light.
  3. Position tubers just below the compost surface, with the indented (hollow) side facing upwards.

Hardening Off (After risk of frost has passed):

  1. Gradually acclimatize plants to outdoor conditions over 7 to 10 days.

Planting Outdoors:

  1. Choose a sunny or semi-shaded position.
  2. Ensure the location is protected from strong winds.
  3. Plant at their final positions, maintaining spacing for up to 30cm spread.

Care:

  • Watering: Keep soil consistently moist but not waterlogged.
  • Feeding: Use a balanced liquid fertilizer during the growing season.
  • Deadheading: Remove spent blooms to encourage further flowering.
  • Overwintering: As a half-hardy tuber, they should be lifted and stored in a frost-free, dry place over winter, or treated as annuals.
