- Soil requirements: Calibrachoa petunia flower seeds prefer well-draining soil with a pH level between 5.5 and 6.0. The soil should be rich in organic matter to support healthy growth.
- Sunlight needs: These seeds require full sun to partial shade. Ideally, they should receive at least 6 hours of direct sunlight daily for optimal blooming.
- Watering requirements: Calibrachoa petunia flower seeds need regular watering, especially during dry periods. The soil should be kept consistently moist but not waterlogged. Watering should be done early in the morning to allow the foliage to dry out during the day.
- Planting season: The best season for planting Calibrachoa petunia flower seeds is in the spring after the last frost has passed. They can also be started indoors 6-8 weeks before the last expected frost date.
- Depth and spacing: Plant the seeds at a depth of 1/8 inch and space them about 6-12 inches apart to allow for adequate air circulation and growth.
- Germination time: The seeds typically germinate within 7-14 days under optimal conditions.
- Maturity time: Calibrachoa petunia flowers usually reach maturity and start blooming within 10-12 weeks after planting.
- Harvesting time: The best time to harvest the flowers is in the early morning when the blooms are fresh and fully open.
- Harvesting tips: Use clean, sharp scissors or pruning shears to cut the flowers. Regular deadheading (removal of spent blooms) encourages continuous blooming. Store harvested flowers in a cool, dry place if not used immediately.
