Long flowering, excellent for bedding, pots and hanging baskets. Fill a planting / Seedling tray with damp potting soil. Spread the tiny petunia seeds on the surface of the soil. Press them gently against the soil without covering the seeds because they need light to germinate and then spray water with a sprayer. It is best to start them in trays indoors. Germination will take place in 7-10 days after planting. Harden off the Petunia’s when you are ready to plant them.
