Ok now up to 3 sowings of Pak Choi. each one has caught this heat wave and bolted before hitting an edible size. How's everyone else's and any help avoiding the problem. Will so number 4 this week and attempt to shade them
I sow my Pak Choi and Choi Sum when the days get shorter, in Aug/Sept - that seems to prevent bolting (touch wood). That was a tip I got from Joy Larkcomb's book 'Oriental Vegetables' :)
I've read that you need to water often. Mine have been ok so far even with not watering so no sure really.
Hi Glow,
Same problem here, will wait until later in the season to sow more as overwintering crop.
We’ve made two sowings, and they’ve both bolted. Apparently they don’t like long days.
I don’t know if there’s much we can do about this. I was in Tesco the other week, and their pak choi had bolted too.
Before the longest day, they'll give leaves & then quickly bolt... I deliberately sowed some back in March as an experimental crop. Got enough off to keep me in greens, but they bolted fairly swiftly - never-the-less, I'll do the same next year. Liked them!
If you want the plants to 'heart up' then sow later in the year.
