Know before you buy
Yes, the Shock Wave series is specifically bred for containers and hanging baskets. Their mounded, spreading habit creates a dense canopy that cascades beautifully over the edges of pots.
No, do not cover the seeds. These petunia seeds require light to germinate, so they should be pressed firmly into the surface of the soil rather than buried.
Each plant will spread between 30 and 36 inches. Because of this vigorous growth, ensure you provide enough room in your containers or garden beds to allow for proper airflow.
These petunias perform best in full sun. To achieve the most vibrant color and the densest canopy of blooms, place them in a location that receives at least six to eight hours of direct sunlight daily.
Under optimal soil temperatures of 70-75°F, you can expect germination to occur within 7 to 12 days. Maintaining consistent warmth is key to successful sprouting.
These are annual flowers, meaning they complete their entire life cycle in one growing season. They are designed to provide a high-impact, continuous display of color from spring through the end of the season.
