Be careful about picking weeds just anywhere. They could be sprayed or growing in contaminated soil.
I use to not want weeds in my yard, now i can't grow enough for my tortoises because the chickens eat them all. I have to resort to asking friends for their weeds. They use to look at me weird but now they expect my weird requests each spring for weeds and mulberry leaves.
Me too! And horse manure for my worms!
