Presentations, Workshops, Articles and Research

The Garden Hotline also presents workshops and seminars on natural yard care and integrated pest management (IPM) practices. We work with local community partners to offer free workshops in support of refugee, immigrant, low income, people with disabilities and elder communities in King County. We offer hands-on workshops in the garden, in-classroom container gardening, mushroom growing and micro-green classes, and online virtual classes and presentations for our partner communities.

We offer workshops to senior centers and community council groups made available to their members. Many of our workshops and presentations are open to the public in King County, sponsored by groups like Master Gardeners in King County and cities in the area. Check the calendar for upcoming classes.

We often share articles with local and regional newsletters and home-owner associations featuring topics of relevance to their communities. Articles are also shared on the Garden Hotline website, featuring a seasonal tip four times a year to help you focus on what to do now in the garden.

Can’t find the answer to something and don’t have time to track it down? Let us do the research for you. We can share resources on good plant choices, safe and healthy gardening research and advice, and the local businesses that support natural gardening products nearest to you.

Community Events & Fairs

We share natural yard care information at community events like health fairs, environmental celebrations, neighborhood festivals, and farmers markets. You can find us with a table full of free natural gardening information, free seeds for your garden, and an in person educator available to answer your questions about your yard. Check the calendar listing for local events where you can find us.

In-Language Services

We provide interpretation services to customers who call us and employ interpreters and partner with groups who can provide interpretation when needed in our workshops. Articles have been translated and shared through ethnic media sources as well.

Garden Demonstration Projects

The Garden Hotline staff have developed and currently maintain educational garden features at both the Good Shepherd Center and Rainier Beach Urban Farm and Wetlands.

Projects at Good Shepherd Center

At the Good Shepherd Center, we highlight small space urban garden features in the Children’s Learning Garden including dwarf fruiting trees, fruiting shrubs, a natural lawn, a perennial edible bed, an “Explorer’s Trail” and native plantings to support wildlife. Through funding from a Tableau Community Grant, we have been able to supplement plantings and wildlife features to enhance our project at the Good Shepherd Center. You can join us to learn about small space urban garden care and volunteer in the garden on Wednesdays and Saturdays – we can customize your schedule. Join our Bumble Bee Watch citizen science project to track the bees we see in the summer.

Projects at Rainier Beach Urban Farm & Wetlands

At Rainier Beach Urban Farm and Wetlands, we have been in the process of creating a pollinator-friendly hillside garden in front of the office on site. The garden features many native pollinator, beneficial insect and bird friendly plantings alongside tried and true herbs and perennials. It also showcases some of our local weeds to demonstrate how to build a plant community that can thrive and support wildlife. Through the generosity of the Endangered Species Coalition, we have planted hundreds of shrubs, perennials, and ground-covers across the hillside featuring over 50 species of plants. You can join us to learn about pollinator gardening and volunteer on the hillside on Fridays; 10 a.m.-noon. Visit the volunteer page for more information.
