You're cleared to plant in most areas of the Tahoe Basin. The threat of freezing temperatures exists year round here, but in most cases, by mid-June, even tomatoes, squah, peppers, and tender annual flowers like fuschia and impatiens, can be planted outside and enjoyed for the next three months! This month, please join us for the Home Grown Tahoe class on summer vegetables (see our newsletter), and look for us at the El Dorado County Farmers' Market in South Lake Tahoe. We will also be participating in many summer community events and are always happy to answer plant questions and offer advice.

About the Event

You don’t have to live in the South of France to enjoy Lavender. In our Mediterranean climate, Lavender is a beautiful and fairly drought tolerant and pest resistant garden plant, with a wide variety of specimens in many colors and sizes. Add to that its fragrance and culinary use and you have a plant worth exploring. Join us as we discuss All About Lavender: botany, how to plant, care for, harvest and use. We’ll also teach you to propagate lavender to take home with you.
