Companion plants – nettles
I have heard that plants like stinging nettles increase the oil/resin production of plants growing close to them. If I am growing herbs in pots in a greenhouse for essential oils, is there benefit in putting a couple of nettles in pots with them? Or is the benefit transmitted via the soil ie they have to be planted together (which is not really practical for me)? Thanks very much!

This would be an interaction at the rootzone. This will mean that they need to be planted together to obtain the benefits of being companion plants.
