Keeping cozy with the latest podcast

Gardeners are spending more time indoors than out this time of year, so this week’s podcast features an interview with Dr. Rita Hummel. Dr. Hummel teaches a course on interior plantscaping and is also an expert on plant cold hardiness.  Here she combines both areas to explain chilling injury on tropical houseplants.


The greenhouse that this plant lives in lost its heating system and is now showing signs of chilling injury.

Comparison of three leaves on the same plant.  In the back is a healthy leaf; in the middle is one with initial signs of damage (bronzed areas on leaf), and in front is a severely injured leaf that has already begun to turn yellow.

The podcast also has a couple of interesting news items on compost safety and treating disease with thermotherapy, and finally a discussion about the wisdom of wound sealants.

Enjoy!  And keep warm!
