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

What to plant near Red Jewel — and what to keep away
-
Aromatic HerbsTrialed
Mixed, strong-smelling plantings make brassicas harder for pests to find — real research, modest effect. Keep mint in a pot.
-
DillTrialed
Dill flowers feed the tiny parasitoid wasps that hunt cabbage worms. Let some of it bloom near the bed.
-
Flea Beetle Trap StripTrialed
A trap strip pulls flea beetles off young seedlings. UMN found mixes of three-plus trap species beat any single one.

BeetsTraditional
On the classic chart's companion list for the cabbage family.
-
NasturtiumTraditional
On the WVU companion list, with an aphid-magnet reputation. If aphids pile on, pull those plants before they breed.
-
Onions & garlicTraditional
Old chart pairing; both hold cool-season beds.
-
PotatoesTraditional
Old chart pairing.
-
Beans PoleTraditional
Chart canon says no. Nobody's proven why. Cheap to respect.
-
StrawberryTraditional
Flagged on the classic charts, including WVU's. Mechanism murky; the canon is consistent.
-
TomatoTraditional
Flagged on the classic charts, mechanism murky. Skip the pairing if you've got 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 cabbage.

Growing Red Jewel — the things that trip people up
- If heads split after rain, they’re over-ripe or got a sudden drink — harvest promptly when firm, and keep water even.
- 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.
