I have a gallon water butt and half filled it with comfry and one carry bag of stinging nettles, it is about 4 weeks old now and stinks to high heaven.
Question how much to put in to the watering can, can 2 gallons.

The advice i have been given is to make it look like a weak tea hope this helps cheers Neil.

If it was straight comfrey, for younger plants make it weaker, say 25% tea to 75% water. 50/50 otherwise. Mixed with nettle tea, perhaps dilute further.
