Did you know that you can give too much compost to your garden? Also, there isn’t a “best” fertilizer for tomatoes or roses or trees. Robert Pavlis is a garden writer, speaker and educator with a background in science. He lives in Guelph, Ontario and gardens at his six-acre home called Aspen Grove Gardens. He has published a handful of books and maintains two websites, gardenmyths.com and gardenfundamentals.com. He speaks with Shauna Dobbie, editor of Canada’s Local Gardener magazine, about the nutrients that plants need, dispelling myths along the way.
