I live in Fort Wayne, and the soil is a lot of clay. Can I still plant this tree in December? Will it need watered? Also, one more question please. I’m not […]

Onions Don’t Need To Be a Crying Shame

An onion by any other name still may not smell sweet to most of us. Onions are notorious for causing malodorous breath and a trickle of tears. In both cases, sulfur-containing compounds are the culprits. According to legend, Western cowboys referred to onions as “skunk eggs,” thanks to the sulfur compound’s ability to permeate the lungs.
