I would plant only 1, Other wise it would be too crowded.

Thanks for the reply,
Would chopping them down be sufficient or do I need to remove the roots as well?

Cutting them off at soil level will suffice.

Great, thanks to you too.

Maybe leave 2 for a little while just to make sure at least 1 survives and no accidents happen. You can always cull the other one in a week or so.

Now that you have them, leave 2, (furthest apart in the clump). I am experimenting with double planting. I think 2 of them together may be able to produce as much as a single. But more than two will be crowd. Double planting is quite common in cucumbers, melons and tomatoes cousin potatoes. The difficulty here is managing the top. With good cage and staking that can be handled.
