❓ FAQ Section: Petunia Masterclass Summary
Q1. What is the single most important factor for non-stop Petunia blooms? The most important factor is consistent, intense light (6+ hours of full sun). The second is the combination of regular feeding (every 10-14 days) and the mid-summer chop.
Q2. My Petunia seeds failed to germinate. What did I do wrong? The seeds must be sown on the surface of the soil (they need light to sprout) and require a high, consistent temperature of 75°F to 85°F.
Q3. Should I choose upright or trailing varieties for my window boxes? Use a mix! Place the Upright Petunia varieties in the back or center (the "filler") and the Trailing Petunia varieties along the edges (the "spiller") for a dramatic, cascading look.
Q4. Where can I find bulk flower seeds for commercial-scale bedding plant displays? We specialize in high-yield, high-germination annual flower seeds in cost-effective bulk quantities for market and landscape use. Shop Bulk Site All Packs.
Q5. How do I fix a Petunia that has become long and sparse (leggy)? The only effective fix is the mid-summer chop. Cut every stem back by 50% immediately, and ensure the plant is receiving maximum sunlight.
