Is it worth my investing 2 hours collecting the nettles and starting
this off?
Definitely YES!. We have used this method very successfully for many
years. Nettle infusion is an ideal organic plant feed and insect
repellent, and it is free. I do ours in a 45 gallon plastic drum,
topping up either the water or the herbage as necessary.

Erm...When you say insect repellant...
Will it kill off worms and other 'Nice' creatures?
(Butterflies are MOST welcome in my garden!)

And although I don't like wasps and bees....They do help the garden to a
degree
