Atomic Red Carrot
✓ In your garden
Atomic Red is a red to orange imperator carrot, ready in about 75 days. A good keeper: it stores for months in a cool, dark spot. Carrots want loose, stone-free soil to grow straight — sow the seed directly (they hate transplanting) and thin the seedlings so each has room.
“A sturdy carrot that stores well through winter.”

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

What to plant near Atomic Red — and what to keep away
-
Onions & garlicTrialed
Interplanted onions confused carrot rust fly in some trials and did nothing in others. Worth a try, not a bet.
-
LettucePractical
Quick lettuce fills the row while slow carrots take their time.
-
RadishPractical
Radishes sprout in days, mark your carrot row, and are gone before carrots need the space.
-
PeasTraditional
The classic cool-season pair.
-
TomatoTraditional
'Carrots Love Tomatoes' is a book title, not a trial. They coexist fine — just expect the tomato to shade them by August.
-
DillTraditional
Same family, same pests, and mature dill is said to stunt carrots. 'Said' is doing some work there — but why risk it.
The badge is the honesty. Trialed = a published field trial · Practical = a real mechanism · Traditional = companion-chart lore. These pairings hold for every carrot.

Growing Atomic Red — the things that trip people up
- Straight carrots need loose, stone-free soil — dig it deep and skip fresh manure (it makes them fork). In heavy or rocky ground, grow a short, stubby type or use a raised bed.
- Carrot seed is slow and fussy to sprout: keep the top of the soil damp for two to three weeks, and thin the seedlings so each root has room to size up.
