Bok Choy brings crisp white stems and tender green leaves to the garden, with a mild, clean flavor that works beautifully in quick stir-fries, soups, slaws, and fresh salads. This open-pollinated, non-GMO Asian green is fast-growing, space-efficient, and especially rewarding when harvested young.
History
Bok choy has been cultivated in China for centuries and remains one of the most beloved members of the Asian greens family. Its compact form, quick maturity, and dependable cool-season performance helped it travel from traditional kitchen gardens into home gardens around the world. One bite of the juicy stems and tender leaves explains why this classic green has endured.

Flavor Profile
Bok choy has a mild, fresh flavor with a subtle sweetness and a gentle cabbage-like finish. The thick stems stay juicy and crisp while the leaves soften quickly, giving one plant two useful textures in the kitchen.
When to Plant
Grow bok choy in the cool portions of spring and fall. Start indoors 4–6 weeks before the last expected frost, or sow directly as soon as the soil can be worked in spring; for a fall crop, sow 6–8 weeks before your first expected frost. Check your USDA Plant Hardiness Zone Map for local timing.
Growing Tips & Planting Dimensions
Sow seeds 1/4 inch deep in rich, well-drained soil with plenty of organic matter. Space plants 6–8 inches apart for full heads, or harvest baby bok choy closer together. Choose full sun in spring and fall, with afternoon shade helpful in warmer weather. Keep soil consistently moist and mulch lightly to moderate soil temperature. Harvest promptly in hot weather, since mature plants can bolt when temperatures rise.
- Water at soil level to keep leaves dry and reduce disease pressure.
- Rotate brassicas to a new bed each season when possible.
- Use row cover to protect young plants from cabbage worms and flea beetles.
🌱 Gentle Cover Germination 🌱
Into the surface — thin cover only, no light needed
Bok choy seeds are small, but they quickly grow into sturdy, productive plants. Give them a fine seed-starting mix, a light cover, and steady moisture, and they will get off to a strong start.
How to Germinate Successfully:
-
Start with the right foundation. Use a fine seed-starting mix — not garden soil or coarse potting mix. Sift it if needed. Small seeds need a smooth, even surface to make good contact and germinate reliably.
-
Cover lightly — just barely. Press seeds onto the moist surface and cover with no more than 1/8 inch of finely sifted mix. These seeds do not need light to germinate but they do not want to be buried either.
-
Mist, do not drench. Use a spray bottle to keep the surface evenly moist. Watering from above can wash small seeds away before they ever get started.
-
Warmth is your friend. These seeds germinate best at 65–70°F. A heat mat can help if your growing space runs cool.
-
Trap the humidity. Cover your tray with a humidity dome or a loose piece of plastic wrap. This keeps moisture and warmth stable while you wait.
-
Give them time. Keep conditions consistent, resist the urge to overwater, and expect sprouts in about 4–10 days.
-
Thin with scissors, not fingers. Once seedlings appear, snip extras at the soil line rather than pulling. This protects the roots of the seedlings you are keeping.
Growth Type & Harvest Yields
Bok choy forms a compact, upright rosette rather than a dense round cabbage head. A healthy planting can provide repeated harvests of baby leaves, or full heads can be cut at the base when they reach usable size. Succession sow every 2–3 weeks during cool weather for a steady supply.
Knowing When to Harvest
- Harvest baby bok choy when plants are 4–6 inches tall for the most tender stems and leaves.
- For full-size plants, cut when the stems are firm, white, and crisp before the plant begins to bolt.
- Harvest outer leaves as needed, or cut the whole plant just above the soil line.
- Pick in the cool morning and harvest regularly to encourage a continuous supply.
- Refrigerate unwashed bok choy in a loose bag and use within several days for the best crunch.
