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

- Plant seeds outside

- Growing
- early May – late Jun

What to plant near Perfection — and what to keep away
-
TomatoPractical
Fennel foliage and seed are rich in trans-anethole, and extracts of them held back germination and seedling growth across a range of species in testing. Whole-plant effects at garden spacing are milder than the "fennel kills everything" reputation, but the chemistry is real — give it its own pot.
The badge is the honesty. Trialed = a published field trial · Practical = a real mechanism · Traditional = companion-chart lore. These pairings hold for every fennel.
