Today we celebrate a journal entry about spring and sap and microclimates. We'll also learn about a young Dutch botanist who determined the cause of Dutch Elm Disease. We’ll hear a poem about spring from a beloved English poet. We Grow That Garden Library™ with a book about the Garden from a man who was never in a hurry, who fought to preserve trees, and sought to work with nature. And then we’ll wrap things up with the story of the earliest horticulture society in the United States.    Subscribe Apple | Google | Spotify | Stitcher | iHeart To listen to the show while you're at home, just ask Alexa or Google to “Play the latest episode of The Daily Gardener Podcast.” And she will.
