Dan suggested that 8 seemed like too many, so I managed to limit myself to 10 (see how that math worked?) 4 of these are San Marzano, 3 are Cherokee Purple, 2 are German Johnson, and 2 are German Green. Per the advice of my gardening class, I planted the tomatoes on an East-West line, with the shorter plants (San Marzano) in the front.
Even the "biggest" seedlings looked teeny tiny when planted outside. For each plant, I dug a hole about 4 inches deep, threw some compost in the bottom, and then gently added the plants, keeping them in their peat pots, which will eventually just become part of the soil. I watered them right after the transplanting, and made sure to keep them watered as we went through a hot spell with no rain.
Eventually I will add the same twine lattice system here that I used for the peas and cucumbers, but I figure I can put that off until the plants are a little taller.
