Tomato in a Zone 8 season
Zone 8 gives about 224 frost-free days. Tomato needs roughly 75 days from transplant. That leaves about 149 days of slack, so there is room for a late start or a second planting.
How to grow tomatoes
Start seeds indoors about 7 weeks before you plan to plant out. Harden the seedlings off and transplant once nights stay warm, burying the stem deep for strong roots. In hot, humid climates choose the drier, cooler months, because flowers drop in sticky heat.
