Onion starts on the window sill. Spring must be just around the corner. I asked a friend of mine why she starts hers so much earlier than I do. She said "Because I can!". It's true. It's wonderful to start seeds and see new growth when winter is still clinging to the garden. Onions take so long to grow that you always have some license as to when you can start your seed. I like watering mine every morning.
