You've probably answered this a hundred times already! - I assume that
'nettle infusion' is an organic pesticide - how do you make it?

More like a thousand, but no problem :-)

NO it is not an insecticide, (there's no such thing as an organic
insecticide) it is an insect repellent. '-icides' kill things,
repellents just send them away.

Basically you soak young nettle leaves in water until they biodegrade -
10-15 days, than it's ready to use. Full details in the urg FAQ at:

Have a good supply of pegs ready! :-)
