Scald those pesky weeds with boiling water. Just grab your kettle off the stove and bring it to the garden. Pour a stream of water carefully on the crown of each unwanted plant. Tough perennial weeds with long tap roots may take two or three applications, but will eventually stop coming back. Use your hot pads, of course, and deﬁnitely take the precaution of wearing long pants and close-toed shoes.
