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

Radishes sprout in days, mark your carrot row, and are gone before carrots need the space.
The badge is the honesty. Trialed = a published field trial · Practical = a real mechanism · Traditional = companion-chart lore. These pairings hold for every radish.
Growing Crimson Giant — the things that trip people up
- Speed is the secret to a good radish — grow them fast in cool weather with steady water. Slow, hot, or dry conditions make them woody, cracked, and blistering hot.
- Thin the seedlings early so each root has room to swell, and pull small types promptly — left too long, they split and turn pithy.
