On this edition of ‘Horticulture Day,' Iles and Aaron Steil of Reiman Gardens in Ames join host Charity Nebbe to give tips on planting healthy trees and shrubs. Iles says that trees are now entering their prime root growth period. However, he advises against transplanting trees already in the ground at this time of year.

On this Horticulture Day edition of Talk of Iowa , Iowa State University Entomologist Donald Lewis makes the case for the importance of wasps in Iowa's ecosystem, despite their unpopular presence. He provides information on social wasps, which congregate in colonies and spend their summer gathering other insects as food for offspring. In the late summer season, these wasps reach their peak population and become more visible as they seek out sugar and moisture, Lewis says. "[Wasps] are great biological controls as predators eating other insects, especially eating some of the pests out of our gardens and landscapes," Lewis says. "We should leave them alone. We should tolerate them for the benefits they provide and if they would just nest far away from my front door I would coexist with them very easily." Later on, Lewis and Iowa State University Horticulture Extension Specialist Richard Jauron answer questions from callers about the range of plants and insects in their lives. Guests:
This weekend is the ideal time to improve lawns before fall, according to Iowa State University Extension Turf Grass Specialist Adam Thoms.

Although oak trees are uniquely suited to the Iowa climate and landscape, many suffer from a variety of ailments stemming from insects, fungal problems, and disease. On this Horticulture Day edition of Talk of Iowa, the director of the Insect and Plant Diagnostic Clinic at Iowa State University, Laura Iles, explains common effects of insects on oak trees. She says that after dry weather lace bugs can contribute to the yellowing of leaves. Lace bugs can be identified as black spots underneath yellow leaves, but Iles says it isn't a major concern and recommends not worrying. Lina Rodriguez Salamanca, a plant pathologist and diagnotician at the Plant and Insect Diagnostic Clinic, discusses fungal problems affecting oak trees. She says she has seen a lot of Botryosphaeria Cankers, which cause the ends of branches to turn brown. According to Salamanca, there isn't much to do besides properly mulching and pruning the tree. However, Salamanca recomends waiting until winter to cut branches to
Hibiscus blooms can be big and showy, or small and delicate. Growing hibiscus can be an easy way to add a little bit of exotic beauty to your yard or garden. On this horticulture day edition of Talk of Iowa , host Charity Nebbe and Cindy Haynes, Associate Professor of Horticulture at Iowa State University, chat about how to grow sun-loving, flowering hibiscus plants in Iowa. Hardier hibiscuses do well in well-drained soils outdoors. They die back during the winter and come back during late spring. Tropical hibiscus can survive on a patio in the summer, but need to be brought indoors in September. Haynes recommends checking them for insects before bringing them in. Our horticulture experts also answer questions from listeners. Guests include : Richard Jauron: Extension Horticulture Specialist at Iowa State University Cindy Haynes: Associate Professor of Horticulture at Iowa State University
On this edition of Horticulture Day on Talk of Iowa, h ost Charity Nebbe and Michael Dosmann, Keeper of the Arnold Arboretum, discuss how plant collections are cultivated and evolve. They converse on starting and maintaining museums of trees, such as the Brenton Arboretum in Dallas Center, Iowa that has been developing for just about 20 years. Dosmann says the need for plant exploration and collection has never been greater, since he says one out of five plants globally are threatened with extinction. "Some of these plants are blinking out in front of our eyes," Dosmann says. "And so a lot of botanical gardens around the world are mustering resources to go and botanize and explore some areas of the world and collect seeds and bring them back into cultivation just in case they blink out of existence in nature." Later on, horticulture experts answer questions from callers regarding their plants and gardens. Guests include: Michael Dosmann: Keeper of the Living Collections at Arnold
