- LIGHT: Plant them in a spot with full sun, where they'll get at least six hours of direct sunlight every day.
- SOIL: Petunias are drought-tolerant, but they don't like to be planted in soggy soil. So be sure to choose a well-drained spot. Petunias need to be planted in rich, nutrient-dense soil with plenty of organic matter.
- TALL: Grows up to 14-16 in. tall, 24-36 in. wide.
- BLOOM PERIOD: 'Night Sky' petunias usually unleash their color in summer and continue showing off through the fall.
- GERMINATION: These tiny seeds can take up to twelve weeks to germinate, and they need plenty of sunlight with only a light covering of soil.
