Planting and tending to a vegetable garden is both an art and a science. If all goes well, you’ll be enjoying delicious homemade salads all summer long. But if your tomatoes get too little water, or if the soil is too acidic, or if pests get to the lettuce before you do, then all that hard work may have been for nothing.
Whether you’re a seasoned grower or first-time gardener, it’s never a bad idea to hear what the experts have to say. Years ago there was a radio program in New York called “The Garden Hotline,” hosted by horticultural expert the late Ralph Snodsmith. Every Sunday morning on WOR, Snodsmith fielded listeners’ questions, such as: “Can coffee and tea grounds help acidify my soil? Not to any marked degree. Can seedlings thinned from a row of lettuce be used as transplants? If you’re careful with their tiny roots, yes. Is it better to plant my tomato transplants into the garden on a sunny or cloudy day? Cloudy, since reduced light exposure reduces transpiration.”
This week, Science Friday pays homage to Snodsmith’s original radio program and others like it, answering questions about the science of your summer vegetable garden. Ira is joined by Elizabeth Buck, fresh market vegetable production specialist with Cornell Cooperative Extension, and Gary Pilarchik, hobbyist gardener and host of the YouTube channel The Rusted Garden, to answer SciFri listener questions in front of a live Zoom audience.Recalling The Life Of Benjamin Franklin, Scientist
