Carrot & onion family
PairCarrots with Onions or leeks
Onion scent can help mask carrot rows from carrot rust fly in backyard scales; different root depths reduce direct competition.
In the garden
- Alternate short rows or plant onions down the carrot bed edge.
- Avoid crushing carrot fronds when harvesting scallions.
Spacing & timing
Thin carrots on schedule; onions need their own sun and elbow room—do not overcrowd.
Caveats
- If alliums are too dense, carrots fork or stay small in heavy soil.
