- Soil requirements: Petunias prefer well-drained, slightly acidic soil with a pH between 6.0 and 7.0. They can tolerate a variety of soil types, including clay, loam, and sandy soil.
- Sunlight needs: Petunias require full sun exposure for at least six hours a day. However, in hotter climates, they can benefit from light afternoon shade.
- Watering requirements: Petunias need regular watering, but they do not like to be overwatered. Allow the soil to dry out between waterings to prevent root rot.
- Planting season: Petunias are typically planted in the spring after the threat of frost has passed.
- Depth and spacing: Petunia seeds should be sown on the surface of the soil, as they need light to germinate. Plants should be spaced about 12 inches apart.
- Germination time: Petunia seeds typically germinate within 10 to 14 days.
- Maturity time: Petunias typically reach maturity and start blooming about 12 weeks after sowing.
- Harvesting time: Petunia flowers can be harvested throughout the blooming season, which usually lasts from spring until frost. They are best harvested in the cool of the morning or evening.
- Harvesting tips: To harvest petunia flowers, simply cut the stem below the flower. Regular harvesting or deadheading of spent flowers can encourage more blooms. After harvesting, flowers can be placed in water for a fresh floral display.
