Split heart is a condition of cabbages whereby a large split appears in the head.
Symptoms[]
Summer[]
When heads are mature, a sudden heavy rain may cause heads to crack or split wide open.[1]
Winter[]
In winter the cause is a sudden sharp frost.[2]
Treatment[]
None. The exposed internal tissue soon becomes unusable. Harvest and salvage split heads as soon as possible after they are discovered.[1]
Prevention[]
Cabbage can be harvested anytime after the heads form. For highest yield, cut the cabbage heads when they are solid (firm to hand pressure) but before they crack or split.[1] Foliar feeding at the first sign of trouble helps to harden the leaf tissue, but it is better to prevent trouble by watering regularly during drought.[2]
