Ellen and I planted over 50 tomato seeds today. They came in those packs of 20 little white pelleted seeds in each, but really there are closer to 20 pelleted seeds in each pack. I like using the pelleted seeds; Ellen can pick them up and plant the in the little holes I've pushed in the soil. She had a fine old time poking seeds into the holes, covering them up and, later on, watering them.
Several hours later she came back in the house, inspected our containers and wondered why there weren't any tomatoes growing yet. Time means little when you are 4 years old.
Last year I bought several different kinds of peat pots. This year I am not going to waste my money. I just used empy containers, like sour cream tubs, yogurt cups etc. I am also going to try making my own little pots from newspaper. Seems easy enough.
