My good friend, Al, owner of The Flower Basket in town, shared some information about petunia seeds. Did you know there are close to a quarter million per ounce? The commercial growers developed a machine with tiny tubes which are just narrow enough to suction a single seed. Even his patient and experienced wife/greenhouse partner, Kim, finds it difficult to sow these by hand. Whatever you do, Al said, "Don't sneeze!" while planting them. So though pelleted seeds are expensive, 10 for $2.95 from Pinetree, they made the sowing process easy. They need light to germinate, so you just lay them on the surface of the soil, keep them moist, and give them light.
I "planted" the seed March 1st.
