I'm not sure what's going on with my Bok Choy plants. They are spreading out, more flat than in the tall-celery shape you have described. Maybe I haven't let them grow big enough yet? Will they gain their height as they mature, or do I just have strangely flat plants? This is the first time I've grown Bok Choy, so I don't really know what to expect. Also, my plants seem to be a little 'prickly, ' unlike what I have purchased at the store. What do you think? Help!

This is my first year to grow Bok Choy and I have noticed that it is starting to flower. Should I harvest now or wait until it reaches 12 to 18 inches tall?
It is bolting, so it must be harvested ASAP. This article will explain more:

I planted bok choy from a seedling I bought at a Bunnings store. It's been about a month now and they have gotten stalks with yellow flowers growing from the centers. Is this right? Was I meant to harvest them before this happened? I have no idea about growing veggies but am wanting to learn and grow my own. Please help.
Yes, the plant has bolted and should have been harvested before this. Here is more information on bolting: https://www.gardeningknowhow.com/edible/vegetables/vgen/what-is-bolting-what-it-means-when-a-plant-bolts.htm
You can eat it, but it will not taste as good. Here is some information on growing bok choy: https://www.gardeningknowhow.com/edible/vegetables/bok-choy/planting-bok-choy.htm
This year is our first year for planting a winter garden. We planted Bok Choy - it is really taking off. There is a yellow flower that keeps growing and growing in the center of the vegetable. Do we cut it? Does that mean it is going to seed or leave it alone because that is part of the plant?
Unfortunately, it means that the plant has bolted and is probably not very tasty anymore. Bok Choy and other crops like it need to be harvested before they bolt. Here is more information: https://www.gardeningknowhow.com/edible/vegetables/vgen/what-is-bolting-what-it-means-when-a-plant-bolts.htm
One of my Bok Choy plants has little yellow bud looking things growing out from the middle of the stalk. Does this mean it is going to seed? If not, do you know what it is? Thanks.

I am growing Bok Choy for the first time. Am I supposed to cut off the flowers?
If Bok Choy has flowers, then it has bolted to seed and is passed its prime and must be harvested ASAP. Like cabbages and broccoli, they like to grow in cool weather. Too hot and they will get bitter and bolt (start producing flowers and seed). While edible, you can try to eat them, but they will probably be tougher and more bitter. This article will explain more:

This is in Denver in an amended clay soil. We have had several weeks of 100+ temps daily. The bok choy have not grown beyond about 2 inches tall for the past 3-4 weeks. They aren't dying but also not growing stronger. Solutions?
It is the heat. They will likely bolt. They simply cannot grow properly in those kinds of temperatures. You can try to keep their roots cool, and that may help. But mostly likely, even this will not work in that heat.
In the future, try growing bok choy only in the spring or fall. Over summer, they cannot take the heat.
