I am growing mini bok choy for the first time. It is about 4 inches tall, but is now starting to bloom small yellow flowers. Do I cut off the flowers to give more strength to the leaves or can I leave them on? Thank you very much for your help.
Flowering generally means that your plants have bolted.
There are now varieties that are grown and harvested with the flowers.
Do you know the variety that you are growing?
Here are some links with more information.
