Hello,
A couple of months ago, I bought some small seedlings from one of the big box stores labeled "Japanese Stir Fry Broccoli". The label stated that they were very heat tolerant and could be grown all summer and used in stir frys. Well after transplanting and they had grown a little, I recognized they are actually kohlrabi. They are only about tennis ball sized, but have started to put out small flower buds. Do I need to harvest them now? Will they be too bitter, since they have flower buds. Can I just let them grow and harvest after the weather turns cold again? I've never grown this veg. I see where some people state they even plant them in July, but I'm in northeast Texas zone 8b and it's in the 80s here. It gets into the 100s during the summer. They are in an area that gets late afternoon shade, but sun the rest of the day. BTW, I have cabbage and brussels sprouts growing in the same area that are not bolting. Thanks for any info.
