Want healthier, tastier carrots and fewer pests in your garden? Try planting them with the right companions!
Companion planting is a smart way to naturally support your veggies by pairing them with plants that boost growth, protect against insects, and even improve flavor.
Carrots may seem low-maintenance, but they grow better when surrounded by friendly neighbors. Some plants keep pests away, others loosen the soil, and a few even help your carrots taste sweeter.
It’s a simple, space-saving method that adds variety and balance to your garden. Let’s dig into the best carrot companion plants that can give you a bigger, better harvest!
#1 Onions

Onions are great garden buddies for carrots because they enjoy the same conditions: full sun and consistent moisture. Their strong smell helps mask the scent of carrots, making it harder for carrot flies to locate them.
This natural pest control makes both plants healthier. Try planting onions in neat rows beside your carrots. Keep the soil evenly moist and weed-free to help both crops thrive.
#2 Nasturtiums

These cheerful flowers do more than just brighten up your garden. Nasturtiums act as a trap crop, luring aphids and other pests away from your carrots. Their low, sprawling growth also helps shade the soil and retain moisture.
Tuck a few nasturtiums around your carrot patch to keep insects distracted. Make sure they get enough light and don’t crowd your carrots too much.
#3 Legumes

Legumes are soil superstars that add nitrogen, helping nearby plants grow lush and strong. While carrots focus on their roots, legumes work their magic in the soil. This teamwork helps balance nutrients in the bed.
Interplant carrots with bush beans or peas for best results. Choose varieties that won’t cast too much shade and support them with small trellises if needed.
#4 Sage

Sage doesn’t just smell lovely, it confuses carrot flies looking for your crop. Its strong aroma masks the scent of carrot tops, keeping pests away from the roots. Plus, it adds a fragrant, silvery touch to your garden beds.
Plant sage near the edges of your carrot rows. Make sure it gets full sun and prune lightly to keep it tidy.
#5 Leeks

Leeks and carrots make a clever pairing. Leeks help keep away carrot flies, while carrots help deter leek moths. Both crops prefer slightly acidic, well-draining soil and don’t compete much underground.
Alternate rows of leeks and carrots in the same bed. Water them regularly and mulch between rows to keep the soil cool and loose.
#6 Lettuce

Lettuce is a gentle neighbor for carrots, with shallow roots and fast growth. It shades the soil, helping retain moisture for slower-growing carrots underneath. They also like similar conditions, so they’re easy to grow together.
Tuck lettuce between carrot rows early in the season. Harvest the leaves young to make room as your carrots begin to bulk up.
#7 Tomatoes

Tomatoes can offer light shade and protect your carrot patch from harsh sun. Their dense foliage also confuses carrot flies, acting as a gentle barrier. Some gardeners even swear that tomatoes improve carrot flavor.
Position tomatoes where they won’t overshadow your carrots entirely. Use cages or stakes to lift vines and give both plants room to breathe.
#8 Chives

Like their cousin onions, chives give off a scent that repels carrot flies. Their slender leaves don’t crowd carrot tops, and they bring pretty purple flowers to the garden too. Chives also enjoy sunny spots with moist soil.
Plant chives in clumps near your carrots. Trim them often to encourage fresh growth and use the trimmings in your kitchen.
#9 Radishes

Radishes are fast growers and natural soil breakers, which makes them perfect companions for carrots. As they mature quickly, they loosen up the soil, giving your carrots more space to grow deep and straight.
Sow radishes alongside your carrot seeds. Harvest the radishes in just a few weeks to reduce crowding and open space for the carrots to develop.
#10 Rosemary

Rosemary uses its powerful scent to confuse pests and protect your carrot patch. Like sage, it helps guard against carrot flies, and its woody stems offer a lovely contrast in texture. It also adds an herbal fragrance to nearby beds.
Grow rosemary near carrots, but not too close; it needs drier soil and a bit more space. Make sure it gets full sun and prune lightly to keep its shape.
