Pak Choi - how long in the ground before they are past their best?

[cazp]

My pak choi plants are about 8 inches tall and I have about 10 left (after cooking 2 tonight - they were lovely).

Can I get away with harvesting them over the next month, or will they go past their best in that time? They're under enviromesh to protect them from the sun, caterpillers etc.

I have another wave of pak choi after this lot, so want to spread out the harvest if I can.

Pic find that pak choi can bolt given any excuse so sometimes will stand for a week or two and other times will go over when you've only looked away for 2 minutes so it's a difficult question to answer. If they're already for picking I'd be surprised if they last a month but you may be OK.
