Presenter: Lisa Johnson, Dane County Extension Horticulture Educator

There is gardening life even in the presence of black walnuts that produce a toxin that negatively affects the growth and survival of other plants. Learn about juglone (the toxin), and a number of woody, perennial and vegetable plants that are susceptible to or resistant to juglone.

Lisa has a bachelor’s degree in Horticulture from the University of Wisconsin-Madison and a master’s degree in Life Sciences Communication. Prior to that she spent 8 years working in the horticulture industry.

She has been the Dane County Extension Horticulture Educator since 2004. Among her responsibilities are training Master Gardener Volunteers, providing continuing education for members of the green industry, overseeing management of the Dane County Extension Teaching Garden, and acting as staff for the Dane County Tree Board.

She gives frequent presentations to garden clubs, schools and libraries in southern Wisconsin, has a weekly column in the WI State Journal and is a regular guest on Larry Meiller’s ‘Garden Talk’ program on Wisconsin Public Radio.
