Why is there so much moss this year-it's taking over my garden-help?'
This question from a viewer named Joan strikes a chord with me. I have more moss than grass in my so-called 'lawn'. I talked to the expert botanists at the University of Washington's Washington Park Arboretum; they told me that cool and wet weather aids moss growth. This past winter's La Nina pattern gave us just that. Plus moss tends to continue growing at cooler temperatures in contrast to other plants...which allows it to spread! The Arboretum says the best response is to maintain a regular fertilizing program-moss can't handle the minerals and other ingredients in fertilizers, and will tend to die off.
