Superschmelz Kohlrabi
✓ In your garden
Superschmelz is a giant kohlrabi, ready in about 70 days. You eat the crisp, swollen stem — mild and sweet like a cabbage-turnip, good raw or cooked. This is a giant storage type, bred to grow big — softball-plus — and stay tender rather than woody, so it keeps for weeks into winter.
“A crisp, mild swollen stem — half cabbage, half turnip.”

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 Jun, well before your typical frost (~late Oct).

Growing Superschmelz — the things that trip people up
- A giant storage type — let it size right up; unlike the small types it stays tender, not woody. Harvest before hard frost and it keeps for weeks.
- Brassicas are cool-season — they bolt or turn bitter in summer heat, so grow them in spring and fall. Feed them well and watch for cabbage worms (the little green caterpillars); a floating row cover keeps the moths off.
