I remember reading/watching/hearing somewhere that Nettles can be added to water to make a nice spray.
A couple of questions

1 - How do you make such a brew
2 - Is it feed or insecticide
3 - Is it any good

4 - Does it sting when sprayed onto skin

Be warned! I had mine in a large water butt and after a few weeks decided to remove some of the thicker stems, my hand had a nettle itch for 3 DAYS, rubber gloves next time.

Have to say ... there's nothing "nice" about it  

It absolutely STINKS! Good stuff though. Just don't put the container you make it in,anywhere near your shed or where you might like to sit
