Domakihub How to Grow Pak Choi: From Sowing to Harvest
A fast-growing leafy green that thrives in mild climates and rewards you in under six weeks.

Pak choi (also spelled bok choy) is one of the most satisfying vegetables you can grow in a Greek garden, balcony, or hotel courtyard — it matures in as little as 45 days and tolerates the mild winters that make spring and autumn ideal planting windows in Greece. The video above walks you through sowing and harvesting the plants visually; this guide breaks down each stage into clear, actionable steps so you can get consistent results. Whether you are tending a private garden, a holiday rental plot, or a hotel kitchen garden, pak choi is a high-yield, low-effort addition worth growing.
Why Pak Choi Works Well in Greece
Greece's temperate climate is well-suited to pak choi, which prefers cool growing conditions rather than summer heat. The sweet spots are March to May (spring crop) and late August to October (autumn crop), when daytime temperatures sit between 10 °C and 21 °C. Summer heat above 25 °C triggers bolting — the plant runs to seed before the leaves mature — so timing your sow dates around Greece's hotter months is the key decision.
Container growing on a shaded terrace or inside a polytunnel extends the season and protects against the worst summer spikes. For holiday rentals and hotels with kitchen gardens, an autumn planting timed to October–November can supply fresh greens through early winter, when cool nights keep the flavour sweet and the leaves crisp.
Choosing a Variety
Two main groups suit Greek conditions: standard-size pak choi (heads around 25–30 cm, harvested whole after 6–8 weeks) and baby or mini types (harvested cut-and-come-again from 30 days). Baby varieties such as 'Joi Choi' or 'Canton Dwarf' are especially practical for containers or small raised beds, and for catering operations where a steady supply of tender small leaves is more useful than large heads.
White-stemmed varieties are the most widely available in Greek seed suppliers and garden centres; green-stemmed types are slightly slower but handle a little more warmth. For a first grow, a white-stemmed baby variety reduces the risk of bolting and gives you results quickly enough to diagnose and adjust before the season ends.
How to Grow Pak Choi: 5 Steps
- 1
Prepare your soil or container
Pak choi is a hungry, fast feeder. Work in a generous layer of compost or well-rotted manure before planting — roughly 5 cm dug into the top 20 cm of soil. Aim for a pH between 6.0 and 7.0. In containers, use a rich multi-purpose potting mix and choose a pot at least 20 cm deep. Good drainage is essential: waterlogged roots cause rot in the Mediterranean's occasional heavy autumn rain.

Sow seeds in the right window
Direct-sow seeds 5 mm deep in rows 30 cm apart, or start in seed trays and transplant at the 2-true-leaf stage to minimise root disturbance. Sowing directly into the ground where plants will grow reduces transplant shock, which can itself trigger early bolting. Water gently after sowing and keep the soil evenly moist — pak choi germinates in 4–7 days at temperatures above 10 °C.
- 3
Thin seedlings to the correct spacing
Once seedlings reach about 5 cm tall, thin them to one plant every 15–20 cm for baby varieties, or 25–30 cm for full-size types. Crowded plants compete for moisture and nutrients, produce thinner stems, and bolt earlier. The thinned seedlings are edible — add them to salads immediately rather than discarding them.
- 4
Water consistently and feed lightly
Pak choi needs steady, even moisture throughout its short growing cycle. Irregular watering — common in Greece's drier spring — stresses the plant and accelerates bolting. A layer of mulch around the base retains soil moisture and keeps roots cool. A diluted liquid feed (balanced NPK) every 10–14 days is sufficient; avoid high-nitrogen feeds late in the cycle, which promote soft growth attractive to pests.
- 5
Harvest before the plant bolts
Begin harvesting baby varieties when outer leaves are 10–15 cm long, cutting them at the base and allowing the centre to regrow for a second flush. Harvest full-size heads by cutting the whole plant at soil level once the head feels firm and compact — this is usually 45–60 days from sowing. If you notice the centre beginning to elongate and lighten in colour, harvest immediately regardless of size: that is the first sign of bolting and quality declines rapidly from that point.

FAQ
- Can I grow pak choi in summer in Greece?
- Standard summer conditions in Greece — temperatures regularly above 25–30 °C — cause pak choi to bolt quickly, so a full summer crop is not recommended outdoors. However, you can succeed with a shaded container on a north-facing balcony, inside a greenhouse with ventilation, or by choosing heat-tolerant varieties. The safest approach is to skip mid-summer and focus on the spring (March–May) and autumn (August–October) windows.
- How do I prevent flea beetle and caterpillar damage?
- Pak choi is a brassica and attracts flea beetles (small holes in leaves) and caterpillars from cabbage white butterflies. The most effective defence is a fine insect mesh (enviromesh) laid directly over the plants from sowing. Crop rotation — not growing brassicas in the same soil two years running — reduces overwintering pest populations. Avoid heavy pesticide use near kitchen gardens at hotels or rentals where food safety matters.
- How long does pak choi take to grow from seed to harvest?
- Baby and mini varieties can be ready for a first cut-and-come-again harvest in 30–35 days from sowing. Standard full-size heads typically mature in 45–60 days. This makes pak choi one of the quickest-maturing vegetables you can grow, which is particularly valuable for hotel or rental kitchen gardens that want a regular rotation of fresh produce through the season.
