Get Jazzed for Spring!  Join the Delaware Master Gardeners in this day of learning designed for both novice and experienced gardeners. Featuring a variety of topics and sessions, giveaways, refreshments including farm-fresh UDairy ice cream, and an opportunity to network with other gardeners including our expert Master Gardeners! Our focus on gardening essentials will help you with everything from seed starting to garden plantings.  Sessions as follows:

Vegetable Seed Starting with Rick Judd Many vegetables can be started indoors to be transplanted later when conditions are right. Learn which vegetables are customarily started indoors under grow lights and which vegetables are better suited sown directly in the soil. In this session we will discuss the factors and protocol of starting seed by both methods as well as optimum conditions for seed starting. You will also learn methods of testing seed viability, proper storage, and seed saving.

A New Approach to Companion Planting: Adding Diversity to the Garden with Judy Hough-Goldstein Learn how to use diverse plantings in your garden to attract and support beneficial insects and reduce pest problems. In this session you will learn the myth, and the reality of companion planting, learn techniques to attract beneficial insects, and ways to use plant combinations to create a healthy garden.  Click here for more information.

Dahlias with Anne Boyd Expand your plant palette to include dahlias, a tender ornamental that grows from a tuber. Learn how dahlias can carry your flowering border through the August doldrums, and continue blooming up until frost. This session will also feature a hands-on activity on dividing tubers that you can take home to add a bright burst of color into your fall landscape!
