About Pak Choi 'Feng Qing'

Brassica rapa var. chinensis 'Feng Qing' · also called Feng Qing bok choy, green pak choi · edible

'Feng Qing' is a green-stemmed pak choi prized for tender, uniform heads and reliable performance from baby-leaf size up to full maturity in about seven weeks. With pale green petioles and smooth green leaves, it suits successional sowing across the cool seasons and is well-loved for stir-fries, light braises, and salads when harvested young.

Mature size: About 20-30 cm (8-12 inches) tall and wide at harvest; cut earlier for baby pak choi.

Watch for — Flea beetles: Tiny jumping beetles shothole the leaves and stunt seedlings. Use fine insect netting from sowing and keep plants well watered and vigorous.

Indoor size vs how big it gets in the wild

Pak Choi 'Feng Qing' reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back. Indoors and in a pot, expect about 20-30 cm (8-12 inches) tall and wide at harvest. In the ground with no restriction it is a completely different plant — cut earlier for baby pak choi. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.

Growth rate and years to mature

Pak Choi 'Feng Qing' is a fast grower. Realistically, expect a single growing season — it reaches full size in one year, then is done. Its feeding profile backs this up: feeds heavily for a leaf crop. incorporate compost at sowing and apply a balanced or nitrogen-leaning liquid feed every 2-3 weeks for tender, fast growth.

How to keep pak choi 'feng qing' smaller

You are not stuck with the maximum size. For pak choi 'feng qing' specifically, these are the levers, in order of impact:

Choose a compact or dwarf variety of pak choi 'feng qing' from the start — that is the most reliable size control for an annual.
Grow it in a smaller container to naturally limit how large it gets.

Sow a little later or space plants closer if you specifically want smaller individual plants.

How to grow pak choi 'feng qing' bigger or faster

Feed appropriately for the crop and never let it check (stall) from drought or cold.

Light is almost always the ceiling. The pak choi 'feng qing' light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When pak choi 'feng qing' outgrows the room (or the pot)
