(Best months for planting Pak Choy in New Zealand - cool/mountain regions)


  • Easy to grow.
  • Harvest in 45-80 days
  • Sow in garden. Sow seed at a depth approximately three times the diameter of the seed.
  • Best planted at soil temperatures between 21°C and 30°C.
  • Space plants: 30-40cm

Similar to Chinese cabbage but the leaves are smoother and the stalks are longer and thicker. Grows quickly and will also go to seed quickly in hot weather. Best grown in cooler months.

Needs plenty of water.

Culinary hints - cooking and eating Pak Choy


You can treat Pak Choy as "cut and come again " or use the whole plant in one go, whichever suits your needs.

A few weeks ago I planted some pak choy seedlings in a pot. They appear to be doing well but I'm not sure what they should look like when it's time to harvest them. The leaves also seem quite fragile and with the recent heavy rain and wind some of the leaves have been damaged.

We have harvested some of ours from what we planted in early March. I germinated seeds in a seed tray and transplanted them after about 4 weeks when there were four leaves. For a few weeks they seemed to be dormant and didn't grow much and then all of a sudden they started thriving and you could see changes everyday. You will need to feed them a few times when they start growing fast, and in another month time you will be able to harvest them. I was worried about them too when we had the first bad weather but they all survived.

Hi everyone I have started growing some pak choy as i got some cheap seedlings they have grown very fast compared to my cauli,broccoli,spinach and pretty much everything else I am just wondering is there any tell tail signs or size telling when they are ready for me to harvest them Thanks

Pak choy grow quite quickly and you can use them at any size that suits you. Either cut off a few leaves or cut the whole plant. Don't leave too long as they will go to flower and seed and then are not much use as a green vege.

I planted my pak choy seedlings in the garden and they have been severely eaten by something! I'm not sure it's slugs/snails because I have lettuce, spinach and silverbeet seedlings near by which have not been touched. Any insights? Thanks!

I have planted pak choy seeds a couple of weeks ago and they have com up real fast but lots of them. I have never grown them before from seed, how do I thin them out and when should I do this. thank you in advance. Mrs V.

V J If you leave your seedlings till they are about 8cm, you will be able to eat the thinnings. Just pull out a few at intervals down the row. Then do it again a few days later, until you have some plants spaced out to leave to grow. They will go to seed quite quickly now the weather has turned so hot, so you might need to use them while they are still small.

In reply to Sam Oct 10 - last season my Pak & Bok- Choy were heavily targeteted by White Butterfly. Thin yellow eggs appeared on the underside of leaves - every day & the caterpillars hid in the leaf clefts during daytime. I used a pyrethrin spray with minor success, digital removal was more effective but time-consuming.

If the bak choi has gone to seed, can you still eat it? the brought some plants and within days of planting they had flowers on them. Taste ok when i pick them.
