In Louisiana: watch for
The pests that find carrots here.
With about 276 frost-free days, carrot spends longer in the ground here than in most of the country, which widens the window in which carrot rust fly can find it. Scout weekly from midseason and act on the first signs.
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: Louisiana gives carrots about 276 frost-free days, and it needs roughly 68 days to a first harvest. That fits about 10 re-sown rounds across the season, so you can keep it coming instead of picking once.
