In Arkansas: watch for
The pests that find carrots here.
A middle-length season, about 225 frost-free days, means carrot overlaps carrot rust fly for a stretch each summer. Check plants every week or two and treat early.
Rusty tunnels in the roots and stunted tops.
Organic fix: Cover the row; rotate away from last year's carrots.
Big green-and-black striped caterpillars on the foliage.
Organic fix: Handpick (or leave for swallowtails); Bt if heavy.
Brown spots ringed in yellow on the oldest leaves first, darkening until the tops look scorched.
Organic fix: Water at the base rather than overhead, turn under old carrot tops, and leave 2 years between carrot crops.
Your season math: Arkansas gives carrots about 225 frost-free days, and it needs roughly 68 days to a first harvest. That fits about 8 re-sown rounds across the season, so you can keep it coming instead of picking once.
