Foraging is a lot of fun, but be aware, wild isn't always free. There are rules to consider.
Always POSITIVELY identify plants; don't just take MY word for it, and don't assume anything!! Use field guides, picture books, internet pictures, etc. to identify plants. When trying a new food, use caution, and only taste a little bit. Be aware of how your body reacts. Be positive before you proceed.
Foraging on your own property is best. You know what chemicals have been used, and when you last sprayed.
Find out who OWNS the property on which you are considering your foraging adventure. And always get permission from the property owner. Trespassing is a BAD thing, and hardly worth the trouble for a few free nibbles.
When foraging in public places, like parks or forests, it's good to get permission there too. Some parks allow plant collection if you have their (written is best) permission.
Never forage along busy roadsides: car exhaust or road runoff can be toxic, ruining the plants, and your experience. Also avoid the edges of farm fields or waterways that may receive pesticide residue.
Be aware of endangered or threatened species. If there is only a little, leave it. If there is plenty, only take as much as you plan to use. And remember to leave the roots unharmed, so the plants can grow more of whatever you just harvested.
So important!! Remember to be a good steward of the earth, leaving enough for the animals who depend on Nature for their food.
HAPPY FORAGING!!
