Leah Puhlman
OSU University Master Gardener
A life-long gardener, Leah has always had an interest in sustainable gardening practices. In 2012 Leah and her husband Mark started to transform our half-acre suburban lot from mostly grass and invasive blackberry and ivy to a habitat-friendly garden. It was then that they got involved in the Backyard Habitat Program, and really started to learn extensively about habitat.
In 2019 Leah became an Oregon State University Extension Master Gardener and has since focused on teaching others about gardening for bio-diversity through webinars, speaking engagements, and garden tours.
