Tom Soulsby tells us about the plants that went into each of the 65 troughs in the Heritage Garden at the Chicago Botanic Garden. He also shows us how to protect cool season annuals from frost since they still don't like freezing temperatures (much like us!)
These are absolutely beautiful, just love them. What size are the troughs? 2ft x 3ft ? Also how do you fertilize?
