How to tell it is ready

Baby bok choy can be harvested when plants are about 4 to 6 inches tall, while full heads are ready when they feel solid and reach usable size for the variety. Stems should be thick and crisp, leaves smooth and fresh, and the plant should not be stretching into a flower stalk.

How to harvest

For whole plants, cut at the base just above the soil with a knife. For a longer harvest, remove outer leaves individually and leave the center growing point intact.

Timing

Depending on type, bok choy is often ready in about 30 to 60 days. Harvest in cool weather, ideally in the morning, and make multiple passes if you are picking outer leaves. Spring and fall crops usually give the best harvest window.

After the harvest

Shake off loose soil and cool the harvest quickly. Rinse if needed, dry thoroughly, and refrigerate. Avoid leaving wet heads packed tightly, since they lose quality faster.

Tips

Use cut-and-come-again harvest on larger plants by taking outer stalks first. Do not wait too long once heads size up, especially in warm weather.
