The warm spring weather has brought people outside to their yards, and while they are places for gathering and personal relaxation, they are also part of the local ecosystem and should be sustainably managed.

To educate the public how to go about doing that, Sustainable Princeton is presenting an outdoor Sustainable Landscaping Mini-Expo at the Princeton Shopping Center on Saturday, April 24, from noon to 3 p.m.

Attendees will have an opportunity to explore best practices in sustainable landscaping by checking out electric landscaping equipment, learning about organic lawn care techniques, and diving into native plants.

Quiet Princeton, a group focused on reducing the use of loud and environmentally wasteful leaf blowers, will provide advice on sustainable landscaping and mulching.

Native plant garden designer Judith Robinson will share her knowledge about native plants and show off a few that might work in your garden. In addition, The Watershed Institute, D&R Greenway, and Princeton’s Shade Tree and Environmental commissions will share additional best practices.

The Mini-Expo will offer several models of electric landscaping equipment for attendees to check out. A few “green” residents will be present to show off their favorite battery-powered mowers, blowers, tillers, leaf shredders, hedge trimmers, line trimmers, and more.

This event will be held outdoors in the courtyard of the Princeton Shopping Center to maintain social distance. Attendees are asked to wear a mask and stay home if they feel unwell. To encourage sustainable transportation, attendees are encouraged to bike to the free event. Princeton Bike Advisory Committee (PBAC) will be onsite hosting a bike valet near the Verizon store for all attendees.

In advance of the event, Sustainable Princeton is also hosting a webinar on Wednesday, April 21, from 7 to 8:30 p.m. on Princeton’s “Changing the Landscaping: Healthy Yards = Healthy People” project. To register visit
