Zone 6bGreenhouse or cover on: your start slides ~4 weeks earlier and your harvest stretches ~3 weeks later (shown striped).
Planting seeds straight in the ground only works where the season's long and warm — most gardeners start seeds indoors or buy young plants, or you'd pick your first tomato right as frost hits.
Comfortable — first ripe fruit lands around mid May, well before your typical frost (~late Oct).
- Start seeds indoors
- mid Feb – early Mar
- Toughen up outside
- mid Mar – late Mar
- Move plants outside
- late Mar – early Apr
- Plant seeds outside

Growing Flash — the things that trip people up
- Pick the older outer leaves from the bottom and leave the center growing — one planting feeds you for months, and a frost only makes the leaves sweeter.
- Collards shrug off summer heat better than most brassicas and only sweeten after frost, so they crop from spring right through winter in mild areas. Feed them well and watch for cabbage worms (the little green caterpillars); a floating row cover keeps the moths off.
