I'm worried about the tomato sprouts. TH's sister advised us that it's difficult to grow tomatoes from seeds. She added that people usually buy the plants instead. In addition to this, I had transplanted the sprouts to larger pots and they don't seem to be doing well. As a result, I searched online for advice about growing tomatoes from seeds and found these great instructions and tips from Renee's Garden and A way to garden.
I was surprised to learn that the tomato sprouts needed to be kept warm until they are further along in their growth and development. I also didn't realize each sprouted cell should be planted in a single pot. I planted each bay in a 6" planter with the thinking that I'll eventually plant each individual plant in larger containers when they look hardy enough to grow on their own. I may have to divide them up sooner than expected. Despite learning about proper tomato gardening after the fact, I'm hopeful that at least one tomato sprout will survive from each planter.
