Petunia Care Essentials: Sunlight, Soil, Watering, Fertilizing, and Temperature Guide
- Sunlight: Petunias thrive in full sun, needing at least six hours of direct sunlight daily to produce abundant blooms. While they can tolerate partial shade, their flowering may be less prolific.
- Soil: They prefer well-drained, fertile soil with a slightly acidic to neutral pH. Amending the soil with organic matter can help improve drainage and nutrient content.
- Watering: Petunias require regular watering, especially during hot and dry periods. However, they are somewhat drought-tolerant once established. It’s important not to overwater, as soggy soil can lead to root rot.
- Fertilizing: Regular feeding with a balanced, water-soluble fertilizer encourages continuous blooming. Petunias benefit from fertilizers that promote flowering, such as those high in phosphorus.
- Temperature: Petunias are warm-season plants that grow best in temperatures between 60-75°F (15-24°C). They can be sensitive to frost, so it’s important to plant them after the last frost date in your area.
