Our robust Toronto winter did not deter the dandelions around here. They have come up with great vengeance. Last year I had them under control. That is, I couldn’t eliminate them, but I kept them down to a manageable plantation. Over the winter they seem to have multiplied by many times. I guess the consolation is that we are no longer pumping poisons into the ground to kill the weeds.

Embrace them! A well made dandelion wine is a beautiful thing indeed. Then just eat the rest of the plant. This isnt a problem it is an opportunity.
John Seymour was a British gardening author who once wrote that he wasnt able to grow grapes because every year the pheasants ate them all. He said that was fine because he ate the pheasants.
