Placing the trays or containers on top of the refrigerator is beneficial as the heat from the appliance keeps the flower seeds consistently warm. Five or six weeks after sowing the seeds, transplant seedlings into 3 inch pots, and grow on in cooler temperatures with plenty of light. Harden young plants for 10 - 14 days before planting outdoors after last frost date. When planting outdoors, pinch the young Petunia seedlings back to encourage branching.
