I had to look up stem cabbage because I'd never heard of it before. I think it's the same thing as kohlrabi, so I'm proceeding as if that's the case.

I'm not an expert with kohlrabi, but they look fine to me. You may want to direct your question to the square foot gardening forum, though.

To respond to you other question, they do not look leggy. They are supposed to have long stems with leaves like that. The bottom is devoid of leaves because that's where the bulb forms. The leaves are perfectly edible (like kale), so if you choose to remove some of them early do not toss them in the compost!

First of all thank you for the quick response.

Yes it is kohlrabi, they also known as cabbage turnip, stem cabbage and turnip cabbage I think.

Some of them are forming bulb some are not so I was thinking it may be cause of too close to each other. I will try the square foot gardening forum for further information.

Thank you again for the advice.

One other thing to add...Once you harvest the mature bulbs, if spacing was a problem, perhaps the other ones will then have the space they need to develop. I've noticed that it can be very slow growing. It can hang around for quite a while, biding its time, and then suddenly mature.

They should be okay. Remove some one or two at a time, eat them, and let the others get bigger.

Thank you Annew21 and Noki for the feedback.
