How Do I Know When My Cabbage Is Ready to Cut?

Knowing when to harvest a cabbage is straightforward once you know what to feel for. Unlike some vegetables with dramatic visual harvest signals, the primary test for cabbage readiness is tactile — the head should feel solid and dense when pressed firmly with the palm of your hand. A head that gives and feels spongy or hollow is not fully formed; a head that feels like a firm ball with no give is ready to harvest. Leaving it too long after this point risks splitting, bolting, and pest damage to the standing head.

The firmness test

Press the top of the head with the heel of your hand, applying firm, steady pressure. A ready cabbage resists firmly — there is almost no give or flex. An unready head feels soft or springy. This test works for all heading cabbage types: round ball-heads, pointed spring types, and savoy varieties. The test does not work for loose-leafed types (spring greens, or immature heads harvested as loose greens) where the head, by definition, has not fully tightened.

How to cut

Use a sharp knife and cut through the stalk at the base of the outer leaves, leaving as few outer leaves on the head as possible for storage but being careful not to cut into the head itself. A clean, sharp cut is preferable to sawing. If you want a second harvest from the stump — small leafy side-shoots sometimes develop from the cut base and can be harvested as greens over the following weeks — leave a 5–10 cm stalk in the ground and notch the cut surface in a cross pattern with the knife before leaving the plant.

Seasonal timing

Summer cabbages are typically ready from July to September. Autumn cabbages from September to November. Savoy and winter cabbages from October through to February or March. Spring cabbages from April to June. The variety's seed packet will indicate the days-from-transplanting-to-harvest, which is a useful guide, but the firmness test overrules the calendar — harvest when the head is solid, not when the calendar says it should be ready.
