Equinox was last week and it is definitely time to start your tomato seedlings. In addition to Brandywine tomatoes, you could branch out and try Amish Paste or Cherokee's Purple. Elinoar ordered seeds from Fedco, a gardening cooperative in Maine. Most of their seeds are organic. We have an assortment of vegetable, herb and flower seeds.
She also ordered small, cheap (25 cents) packets of seeds from Artistic Gardens in Vermont. You only need a few seeds to start tomatoes or herbs. And if you have never gardened before, it is a very economical way to give gardening a try on your fire escape or roof.
In a week or two there will be more flower, herb and vegetable seeds from Seeds Savers Exchange.
Seeds are being sold in the produce aisle near the potatoes. Also look for gardening books in the rack nearby. Topics include container gardening, herbs, organic practices, gardening with kids , etc.
