Q: How do I start tomato seedlings indoors?
A: To grow your own tomatoes for transplanting outdoors, sow the seeds indoors four to six weeks before the usual last frost (around May 15 in the Chicago area).
Use a sterile seed starting mix and any containers that will hold soil, provide drainage, and accommodate growing roots. Moisten the soil, place two seeds in the pot, and cover lightly with more soil mix. Cover the pots with clear plastic to keep the soil evenly moist and place the plants in a warm location until germination occurs.
