How cold is it where you are because may be from big change in temperature from day to night  and the short days  may not help.Planted potatoes 4 months ago and think that to get good results in winter need to be in full sun and no shadows  as even though in open area got fantastic results from those away from any shade.

We had a big feed of Choy Sum on last Sunday night. They were a bit lanky when picked.
My bok choy, on the other hand, has been great. I've been able to harvest as needed -- one at a time.
I prefer bok choy anyway.
The Choy Sum had a little bit of stringiness towards the base of the stems. Not much leaf -- like yours. And a couple had early flowering.

Interesting point Andrew. I would say ‘yes, full sun all day’. The others seems OK and to be honest, I’m sure I’ll be up to my neck in it before I know it. I will however check just how much sun they get at various times in the day.

Did it have enough sun?  I noticed my lettuce used to bolt if they didn't get enough sunlight (as well as in the heat).
