- Soil requirements: Viola tricolor prefers well-drained, fertile soil with a pH level between 6.0 and 7.0. The soil should be rich in organic matter to support healthy growth.
- Sunlight needs: These flowers thrive in full sun to partial shade. They require at least 4-6 hours of sunlight daily for optimal blooming.
- Watering requirements: Viola tricolor needs consistent moisture, especially during dry periods. Water the plants regularly, ensuring the soil remains moist but not waterlogged. Avoid overhead watering to prevent fungal diseases.
- Planting season: The best time to plant Viola tricolor seeds is in early spring or late summer to early fall. This allows the plants to establish before extreme temperatures set in.
- Depth and spacing: Sow the seeds at a depth of 1/8 inch (3 mm) and space them about 6-8 inches (15-20 cm) apart to allow for adequate air circulation and growth.
- Germination time: Viola tricolor seeds typically germinate within 10-14 days under optimal conditions. Maintain a consistent temperature of around 65-70°F (18-21°C) for best results.
- Maturity time: Viola tricolor flowers usually reach maturity and start blooming within 60-70 days after planting.
- Harvesting time: The best time to harvest Viola tricolor flowers is in the early morning when the blooms are fresh and vibrant.
- Harvesting tips: Use sharp scissors or pruning shears to cut the flowers just above a leaf node. This encourages further blooming. 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.
