most popular organic fertilizer in France?
 

I was looking for information about nettle tea, which I make in the winter, and I found this website

which says nettle tea is the most popular fert in France!

It's diluted to 10% as a soil drench or used neat as an herbicide.

This website says it can be used as an insecticide, too.
