When to Harvest Cabbage
Harvest cabbage when the head feels solid and firm when squeezed gently, before it splits. Most heads mature 70 to 120 days after transplanting, with timing shaped by variety and season.
A mature cabbage head should feel dense for its size, with leaves tightly wrapped. Head diameter is useful only as a rough guide because small, early varieties may mature at 4 to 6 inches while storage types can be much larger.
Use a sharp knife to cut through the stem just below the head. Leave several outer wrapper leaves on the head to protect it during handling, and avoid dropping or bruising it.
Harvest as soon as a head is firm during periods of heavy rain or rapid growth. Mature heads can split when plants take up water faster than the expanding leaves can contain it, particularly after dry weather followed by soaking rain.
If a head is nearly ready but you need to delay harvest briefly, twist the plant a quarter turn or use a spade to sever some roots on one side. This slows water uptake, but it is a short-term measure and heads should still be checked often.
For a possible second crop of small heads, cut the main head high enough to leave the lower stem and several leaves. Small buds may form around the stem; keep the strongest few and harvest them while firm.
Store cabbage cold and humid, ideally near 32°F with high humidity. Refrigerate intact heads in a bag or crisper drawer; early types generally keep for a few weeks, while sound late storage varieties can keep for several months under proper conditions.
Frequently asked questions
What happens if cabbage splits before harvest?
Split heads are still usable if they are clean and sound. Harvest them promptly, trim damaged areas, and use them sooner than intact heads.
Does cabbage need frost before harvest?
No. Many varieties tolerate light frost, and cool weather can improve quality, but firm heads are ready without frost.
Can I leave mature cabbage in the garden?
Only briefly. Mature heads may split, become damaged by weather, or develop pests, so harvest once they are firm.
