Good for you. What variety did you start? When is your last frost date?
Then I also started two yellow ones. Yellow Brandywine which taste better than the Pink Brandywine. Finally Dr. Wyche's which is a fantastic tasting large yellow that weighs 2 pounds plus.
Last official frost date is May 15th. I usually start sooner if I can get out into the garden. I plant almost all of my tomatoes in double 5 gallon buckets. That way I can put them out early. If there is a chance of frost I can bring them in.
