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 6 weeks before your last frost. Harden off and transplant a week or two after frost danger passes, burying the stem deep for strong roots.
