What you need to know to Plant & Grow
Petunias require warm soil temperatures and surface lighting to germinate successfully before being transplanted outdoors in late spring.
-
Indoor Sowing (Recommended): Start pelleted seeds indoors in a sterile soil-less mix 6 to 8 weeks before your last expected spring frost. Surface sow seeds directly on top of the growing medium—do not cover, as light is essential for germination.
-
Pellet Dissolution & Germination: Mist sown seeds gently with water until the protective coating dissolves completely—dissolving the pellet is vital for germination to occur. Apply bottom heat to maintain a soil temperature of 25°C throughout the 14-day germination period (cooler soil will prolong germination time).
-
Growing On & Transplanting: Once germinated, move seedlings under lights at a cooler temperature of 15°C. Harden off young plants before transplanting outside in late May once spring frost risks have passed, spacing plants 20 cm apart in full sun.
-
Care & Maintenance: Water regularly and apply a balanced liquid fertilizer every few weeks to support continuous bloom production and keep foliage lush and healthy.
