Spring Workshop Day Offers Ways to Prepare for Warmer Days

Waukesha County and Johnson’s Nursery, Inc. invite the public to free workshops dedicated to popular springtime topics on Saturday, March 14 from 9 a.m. to 3 p.m. at Retzer Nature Center. Attendees can learn about gardening for pollinators, invasive species, home composting, sustainable home practices, and container gardening ideas.

 “These sessions are a great way for people to engage with local experts to discover new techniques and processes as they prepare their homes and yards for spring,” said Janet Barthel, Nature Center Supervisor. “The support from partners, like Johnson’s Nursery, makes these free programs possible for the community.”

 Each seminar will be led by an expert and will cover a range of information on the topic. Participants are welcome to come for one session or stay for them all. Registration is not required, but is recommended by March 13 at www.waukeshacounty.gov/springworkshops.

Visitors can also take advantage of the one-day Garden Gadget Sale and save $10 on Home Compost Bins or Rain Diverter Kits. Both are on sale for $50. Purchasers must be able to take items home after the workshops. No holds are available.
