In South Carolina: watch for
The pests that find spinach here.
A middle-length season, about 220 frost-free days, means spinach overlaps leaf miners for a stretch each summer. Check plants every week or two and treat early.
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: South Carolina gives spinach about 220 frost-free days, and it needs roughly 42 days to a first harvest. That fits about 26 re-sown rounds across the season, so you can keep it coming instead of picking once.
