- Soil requirements: Petunias prefer well-drained soil with a pH level between 6.0 and 7.0. They can tolerate a variety of soil types, including sandy, loamy, and clay soils, as long as they are well-drained.
- Sunlight needs: Petunias require full sun exposure for at least six hours a day. However, in hotter climates, they can benefit from some afternoon shade.
- Watering requirements: Petunias need regular watering, but they do not like to be overwatered. Water them deeply once a week, and more frequently during hot, dry periods.
- Planting season: Petunias are typically planted in the spring, after the risk of frost has passed.
- Depth and spacing: Petunia seeds should be sown on the surface of the soil, as they need light to germinate. Space the seeds about 12 inches apart to allow for growth.
- Germination time: Petunia seeds typically germinate within 10 to 14 days.
- Maturity time: Petunias usually reach maturity and start blooming about 12 weeks after sowing.
- Harvesting time: Petunia flowers can be harvested throughout the blooming season, which typically lasts from spring until frost. Harvest in the morning after the dew has dried for the best results.
- 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 used immediately or stored in a cool, dry place.
