Diagnosis
Diagnose: Cabbage Loose Split Heads
Use these observations to decide what to check next.
Inconsistent soil moisture causing rapid head growth followed by swelling or splitting
Press the inner head gently rather than judging loose wrapper leaves. A small compact center can still be immature, while a soft open center with no tightening after favorable weather points to stress or growing-point damage.
A firm mature head with a fresh crack has already split and should be harvested because it cannot close again.
