Someone posted wanting to know how to get rid of "pigweed". The pigweed I grew up with was closely related to Lambsquarter, and just as delicious steamed with butter and salt or pepper. Not a tough plant to get rid of really, grew in poor soil well. The kind they were talking about on the board, if I identify the pic right, we call "sticks-in-yer-socks" or "Grass-pers" in our part of Texas. Geese normally strongly prefer grass, or the vegetables in your garden
But we raised our goslings on it sticks to yer socks(sorry don't know the Latin for it), and several other weeds we really wanted them to have a taste for. In addition to grass, Geese will gobble up many broadleaf weeds, but only when the weeds are very young and tender. They won't help with thistles or the really bitter weeds, unless you till and then turn the geese into the area to devour the roots, which don't seem to be bitter to them.
