Eat the Weeds - and other things, too
The quickest and safest way to learn foraging is with a local expert. You not only learn what there is to know but do not spend time learning things you don’t need to know. Further, you also get the local angle on plants, important information that is usually not found in foraging books published on a national or even regional level. The local expert can give you insights to climate and species variation. Also with a teacher you get the opportunity to have your identification skills honed and your judgment sharpened. That builds confidence.
