University of Georgia Going green is a hot topic this year, but recycling isn’t just for household waste. On the May 16 and 20 episode of “Gardening in Georgia with Walter Reeves,” host Walter Reeves and guests will show how to recycle things from the landscape, too. Reeves, a retired University of Georgia Cooperative Extension agent and gardening expert, will visit Hank Bruno at Callaway Gardens to learn how to divide water iris for a pond or water feature, which is a great way to reuse plants. Garden humorist Felder Rushing will show how to turn an old tire into an attractive flower pot. Jim Alston will give pointers on propagating begonias from leaf sections. “Gardening in Georgia” airs on Georgia Public Broadcasting stations across the state each Saturday at 12:30 p.m. and 6 p.m., and repeats Wednesdays at 7 p.m. The show is produced by the UGA College of Agricultural and Environmental Sciences and is supported by a gift from McCorkle Nurseries.
