Once I harvest my bok choy will there be other growing after?
You could try re-growing your bok choy - once you have harvested the whole plant simply chop it at the base and then place it face-side up in a small bowl of warm water. Leave the bowl somewhere warm inside, like on a sunny windowsill, and after a couple of days you should see a new shoot sprout from the centre. After a week or two, when your new bok choy is established, it can then be transferred in to a pot or a warm spot in your garden. Happy growing!
