🌱 Growing Tips for Success
Shock Wave® Denim seeds are pelleted, which means they’re easy to handle and plant precisely. Start seeds indoors 8–10 weeks before your last frost date. Sow them on the surface of moist seed-starting mix, as they need light to germinate.
Maintain temperatures around 70–75°F until germination, then move seedlings to a bright, warm area. Transplant outdoors after the danger of frost has passed, spacing them 10–15 inches apart in full sun.
Fertilize regularly and deadhead to encourage more blooms — though Shock Wave® petunias are known to self-clean and require less maintenance than standard varieties.
