Horticulture Hangover: Sweet potatoes, four o'clocks, and mowing wildflowers

Here's the July 1 episode of Horticulture Hangover, our radio broadcast on KLBJ. We get calls about planting sweet potato slips; four o'clocks failing to bloom; when to mow wildflowers; and how to collect sunflower seeds. Enjoy!  Austin listeners, don't miss Colleen's free class, Native Plant Maintenance, at the Natural Gardener on July 8 at 10am. Tune in to Horticulture Hangover live on Saturdays at 8-9 am CST online here, or on the airwaves: 99.7 AM and 590 FM.
