Many thanks to Marvin Weber and Myron Platte for answering my question about where to find info about weeds. Especial thanks to Marvin for reviewing some of the books. I will check out the four books mentioned, try some ideas on the weeds I struggle with, and see if I agree with the books' suggestions.
I have learned to appreciate some 'weeds' and no longer get exasperated with dandelions, plantain, lamb's quarters, and others. Instead I use them to eat or to make medicinals.
