Shyann's Garden Tour at Herff Farm is a free guided stroll through the Teaching Garden, led by farm manager Shyann. Herff Farm in Boerne is a relaxed countryside spot just outside San Antonio, and this morning tour is a laid-back way to see what's growing. Along the way you'll learn about the crops that are thriving this season and get to ask all the gardening questions you've been saving up. It's free and all ages, so bring the kids, a curious friend or your green thumb.
