Expert Tips

Bolts in heat -- grow in spring/fall. Baby bok choy matures in 30 days. Can be planted 2-3 weeks before the last expected frost, giving it a head start on the growing season. Aim for about 2.5 cm of water per week, adjusting for rainfall. Organic mulch around the base helps maintain even moisture.

Did You Know?

  • 🌱 Bok Choy is frost-tolerant, meaning it can survive light frosts and even thrive in cooler temperatures.

Step-by-Step Growing Guide

Bok choy is a fast-maturing, cool-season Asian green that thrives in 10–20°C temperatures and bolts rapidly in heat. Grow in fertile, well-drained soil at pH 6.0–7.0, rich in organic matter. Sow seeds directly 6mm deep in rows 30cm apart, thinning to 20–25cm apart for full-size plants, or 10cm apart for baby bok choy (ready in 30 days). Alternatively, start indoors 3–4 weeks before transplanting in cooler climates for spring crops. Water consistently and generously — 2.5–4cm per week — as any moisture stress triggers immediate bolting. Bok choy is a heavy feeder: apply a nitrogen-rich liquid fertiliser (fish emulsion) every 10 days for rapid, tender growth. Provide 30% shade cloth if temperatures exceed 20°C to delay bolting. Plant for spring or autumn/winter harvest; summer production is extremely difficult without climate control. Succession-sow every 2–3 weeks through the cool season.

Common Pests & Problems

Flea beetles are the primary pest — they create tiny holes throughout leaves of young plants almost instantly after germination. Use fine row covers from the moment of sowing as the most effective defence. Aphids cluster inside the compact head of full-size bok choy, making them difficult to control — blast with water jets and inspect the heart of each plant daily during warm spells. Clubroot causes swollen, deformed roots and progressive wilting in acidic soils — lime to pH 7.0 and rotate brassicas strictly on a 4-year cycle.

Harvest & Storage

Harvest baby bok choy (10–15cm) by cutting the whole plant at soil level after 30 days. For full-size plants, cut when heads are 20–30cm tall before any signs of bolting. Alternatively, harvest outer leaves from full-size plants for a cut-and-come-again approach. The heads should be compact, with crisp, glossy white stalks and dark green, firm leaves. Store unwashed at 0–2°C in a sealed plastic bag for 4–7 days. Do not store near apples or pears, which emit ethylene gas that accelerates yellowing.

Popular Varieties

Shanghai (Green Stem) is a smooth, light-green stemmed variety with a mild, sweet flavour and tender texture — the most popular baby bok choy type globally. Joi Choi is a large, vigorous, white-stemmed hybrid reaching 35cm with excellent heat tolerance relative to most bok choy — good for home gardeners in variable climates. Black Summer is bred for summer production with better bolt resistance than standard varieties — useful in warmer regions. Tatsoi is technically a sibling species with a flatter rosette and round, dark green spoon-shaped leaves — exceptionally cold-hardy and with a slightly more peppery flavour.
