When our horticulture experts are stumped by a caller, they turn to the experts at Iowa State University's Plant and Insect Diagnostic Clinic.  They identify plant diseases, weeds, mushrooms and insects.  Host Charity Nebbe talks with Entomologist Laura Jesse and Plant Pathologist Lina Rodreguez-Salamanca about the sleuthing that happens in diagnosing a plant disease or insect infestation.

Shocking data reveals more than half of Iowa's trees fall under just two different genera: maple and ash. 

The Iowa Department of Natural Resources Forestry Bureau recently inventoried trees in 273 communities across the state. The results showed that maple and ash trees make up 54 percent of trees in Iowa’s public parks and streets. DNR Urban Forrester Matt Brewer says that the state needs to value diversity and learn from past diseases that hit the tree population.

It's easy to forget about food safety when it comes to garden produce, because growing your own food is considered healthy. Dr. Angela Shaw, an assistant professor of food safety at Iowa State University, says cognizance is key when it comes to food safety in home gardens.

"The first thing is to consider where you place your garden. Thinking about soil: what was previously there? Was there heavy metal? What was your house grown on? We have a lot of swampland as well as chemical landfills that are now communities."
