Horticulture Hangover: Critical root zones, cutting back cannas, and trees in pots

Here's the July 8 episode of Horticulture Hangover, our radio broadcast on KLBJ. We talk about measuring a tree's critical root zone, when to cut back canna lilies to keep them blooming, and how to root-prune trees in pots.   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.
