I love this vegetable, but it goes to seed so quickly, is there any way to stop this ?

You can't! Sow smallish lots every two weeks to get a constant supply. You have to pick the whole vegetable at harvest.

I have been growing Pak Choy/Choy Sum in Sydney, Australia for the last 25 years as I am Chinese in origin. The short fat variety Pak Choy is easier to grow. The long green stem Choy Sum is terribly hard to grow. Don't try in summer months unless you protect them under shadecloth. Need to water them at least twice a day or else you will get flowers within days. Use plenty of mulch and organic fertilzer. They grow very rapidly - 30 days before you pick. So you really need to feed them well. If you can get seeds that are 80 days variety (slow growing) you have a better chance.

I have bought them from a website: newgipps.com.au. There is a 'minimum order', so you would need to order other seeds at the same time, which was what I did. I have also found them under the Mr. Fothergill's brand in the "seeds" section in my local Bunnings or Kmart garden section. also in response to PEEN on Pak Choy, there are various documents on the net, Just do a Google search, eg, 'how to grow pak choy'.

In Tatura (central Victoria) planted pak choy as seedlings from Bunnings not the best soil water every few days Thrive liquid fert. every 2 weeks shadecloth cover over when temp over 40. Don,t pick the whole plant anymore just cut off the leaves needed that day (treat it like silverbeet). Planted these before Xmas and just starting to slow down now,no sign of flowers.

Hi all, I experimented growing pak choy with hydroponics using 100mm plastic down pipes with caps on the ends, and holes cut with a hole saw to take 12 foam cups which were filled with perlite, I cut slots in the side of the foam cups with a gass powered hot knife placed all this on tressels. Had great success, I just picked stems as I needed them, later I used square or oblong down pipe as you just lay them on the tressel no need to tie down, and the round pipe I hung on the fence with rope, worked a treat.

Hi all! I am growing some pak/bok choy in my little organic vegie patch and just as they are getting to a decent size yellow spots are appearing on the leaves... I think they might be borers? Does anyone have any suggestions as to what it could be? Or any tips to fight off/distract these little nasties (organically)???
