Petunia Surfinia Summer Double White Rooted Cutting Liner

For best results with Surfinia Summer Double White, plant one seedling per 4-inch container or three per 10-inch basket. Use well-drained soil with a pH of 5.5-6.0, temperatures of 65-75 daytime and 55-60 nighttime, and medium feed (200 ppm N). This plant is most successfully grown in cool temperatures with high light and moderately dry soil. Provide daylight extension to 14 hours at 4,000-6,000 fc. This plant responds to B-Nine if needed. Pinch 4-inch containers once and 10-inch baskets two or three times. You may see whiteflies, thrips, aphids, and leafminers. Botrytis can occur especially in partial shade or on cool, humid days.

Frilly, double white flowers bloom from April to October.

Pinch 4-inch containers once, 6-inch containers twice, and 10-inch baskets two or three times.

Space containers for adequate airflow and sunlight penetration around the base and foliage of each plant. We recommend spacing 4-inch pots 8" apart, 6-inch pots 10-12" apart, and 10-inch baskets 24" apart. 

Use B-Nine at 2,500-5,000 ppm as needed.

You may see whiteflies, thrips, aphids, and leafminers.

Petunias aren't prone to disease, but Botrytis can develop in short days, low light, or high humidity. Prevent fungal infection and root rot by practicing good sanitation in your greenhouse, watering at the base of each plant and allowing the soil to dry between waterings, and providing good airflow in your greenhouse. Space containers for adequate airflow and sunlight penetration around the base of each plant.

We recommend planting one rooted liner per 4-inch container, two per 6-inch container, or three per 10-inch container. Use a well-drained soil and completely bury the ellepot in the center or evenly spaced in the container.
