Harvesting Split Cabbage Heads
If you’re dealing with split cabbage heads, you’re not alone. Splitting occurs when the cabbage head cracks or bursts before you harvest it. While it can be frustrating, it’s usually not a sign of a serious problem.

Splitting can be caused by several factors, including:
- Overwatering: Too much water can cause the cabbage head to grow too quickly, putting pressure on the outer leaves and causing them to split.
- Drought: Cabbage heads can also split if they don’t get enough water. When the soil is dry, the cabbage plant will draw water from the head, causing it to shrink and split.
- Diseases: Some diseases, such as black rot and soft rot, can weaken the cabbage head and make it more likely to split.
Prevention Tips
There are several things you can do to prevent cabbage heads from splitting:
- Water regularly: Water cabbage plants deeply and regularly, especially during hot, dry weather.
- Mulch around the plants: Mulch helps retain moisture in the soil and keeps the soil cool, which can help prevent splitting.
- Choose varieties that are resistant to splitting: Some cabbage varieties are more resistant to splitting than others. Ask your local nursery for recommendations.
- Harvest cabbage heads when they are mature: Cabbage heads should be harvested when they are firm and the leaves are a deep green color. If you wait too long to harvest, the heads may split.
