In Louisiana: watch for
The pests that find spinach here.
With about 276 frost-free days, spinach spends longer in the ground here than in most of the country, which widens the window in which leaf miners can find it. Scout weekly from midseason and act on the first signs.
Winding pale tunnels or blotches inside the leaves.
Organic fix: Pick and destroy mined leaves; cover the row.
Cercospora leaf spot
Round spots with gray centers and a red-purple rim, oldest leaves worst.
Organic fix: Space wider so leaves dry fast, clear old debris, and pull pigweed and lambsquarters nearby.
Your season math: Louisiana gives spinach about 276 frost-free days, and it needs roughly 42 days to a first harvest. That fits about 34 re-sown rounds across the season, so you can keep it coming instead of picking once.
