Joel Karsten, author of "Straw Bale Gardens," will be at the Royalton Public Library on Monday, April 13 from 3:00 to 4:00 p.m. for an author visit and book discussion. The book describes Karsten's innovative techniques for growing flowers or vegetable crops using prepared straw bales. The technique eliminates much of the manual labor involved in maintaining a traditional garden. Karsten has a degree in Horticulture Science from the University of Minnesota. This program is free and open to the public.
