- Soil requirements: Red Double Begonia seeds prefer well-draining, rich, and slightly acidic soil with a pH level between 5.5 and 6.5. The soil should be kept consistently moist but not waterlogged.
- Sunlight needs: These seeds require partial shade to full shade. They thrive in areas where they receive filtered sunlight or indirect light, making them ideal for shaded garden beds or indoor planting.
- Watering requirements: Water the seeds regularly to keep the soil moist but not soggy. It's important to avoid overwatering, as this can lead to root rot. Watering should be done in the morning to allow the foliage to dry out during the day.
- Planting season: The best time to plant Red Double Begonia seeds is in the spring after the last frost has passed. They can also be started indoors 8-12 weeks before the last expected frost date.
- Depth and spacing: Plant the seeds on the surface of the soil without covering them, as they need light to germinate. Space the seeds about 6-12 inches apart to allow for proper air circulation and growth.
- Germination time: The seeds typically germinate within 14-21 days under optimal conditions. Maintain a consistent temperature of around 70-75°F (21-24°C) to encourage germination.
- Maturity time: Red Double Begonia plants usually reach maturity and start blooming within 12-14 weeks after planting.
- Harvesting time: The best time to harvest the flowers is in the early morning when they are fully open and at their freshest. This is also the best time to collect seeds if you plan to save them for future planting.
- Harvesting tips: Use clean, sharp scissors or pruning shears to cut the flowers. Store the harvested flowers in a cool, dry place if not used immediately. For seed saving, allow the seed pods to dry on the plant before collecting them. Store the seeds in a cool, dry place in an airtight container.
