Yes I do it as I have masses of nettles. One word of warning tho' as the nettles & water brew up in their tub the smell becomes EVIL¦¦  ¦keep the container covered, otherwise your neighbours are likely to complain about it¦.!!

You must add lots of water to the liquid when you feed it to your plants¦.do not use on indoor plants, even when diluted, as you will still smell it. It makes a good foliar feed & seems to deter greenfly etc. Add a tiny drop of washing-up liquid to help it stay on the leaves.

Good luck Janet. 

Aly, I have used it on everything that needed boosting in the garden & have never found it harmed a plant. 

I eat a lot of nettles, especially in the Spring. Thick nettle & potato soup, made with chicken stock is wonderful, nettle & chive Scotch pancakes, & I also make a nettle infusion to drink cold. Only use the youngest top leaves for all of these.
