Growing Tips for Carrots
- Direct sow ONLY — transplanting carrots causes forked, misshapen roots every time.
- Soil must be loose and rock-free to at least 12 inches deep; raised beds are ideal.
- Thin to 3-inch spacing aggressively — crowded carrots fork and grow stunted.
- Light frost improves carrot sweetness — cold converts starches to sugar; fall carrots taste better than spring.
