Dr. Muriel Nesbitt discusses the different species of typically grown squashes and pumpkins at the next Green Thumbs Garden Tips education series session.

Nesbitt will address which varieties cross with which, how to avoid cross pollination, how to hand pollinate and how to approach seed saving, given the possibilities for cross pollination.

Attendees will also learn about squash bees and steps to take that encourage them to visit your garden.

Nesbitt will provide information on the optimal growing conditions, when to harvest and how to store harvested pumpkins and squashes. During her presentation, she will share a few of her favorite jack-o’-lantern images.

Nesbitt earned her PhD in genetics from the University of Washington and taught biology at the University of California-San Diego for 35 years.

She directed the Clallam County Master Gardener program from 2009-2012 and remains a community leader teaching courses, giving lectures, and sharing her knowledge.

Sponsored by WSU Clallam County Master Gardeners, the Green Thumbs Garden Tips education series looks to educate home gardeners on topics relevant to planting and maintaining sustainable gardens and landscapes in Clallam County.

Live streaming presentations are available on the second and fourth Thursday each month through October (in November, December and January, one program is offered).
