Good Neighbor Iowa: Challenging the Idea of a Perfect Lawn

Wed, 04/24/2019 - 11:02
This segment originally aired on May 3, 2017. Spraying herbicide to achieve what many consider to be the ideal lawn became a common practice in the mid-20th century. Many people stopped that practice after studies showing the health impact of human contact with common pesticides and weed killers. "The body of evidence that they are harmful to children is sobering," says Kamyar Enshayan, director of University of Northern Iowa’s Center for Energy and Environmental Education. "There is significant evidence that we ought to stay away from these, and kids should not be exposed to them because of their unique vulnerabilities and frequent hand-to-mouth behavior." Enshayan says that studies found that herbicide exposure in children can lead to conditions including acute lymphocytic leukemia, brain tumors, and interference with brain development. Other concerns include pet exposure, harm to pollinators, and environmental issues relating to water runoff. Enshayan is spreading the message about

Ready, Set, Start Your Seeds!

Fri, 03/01/2019 - 16:18
This winter may feel like it’s never going to end, but spring is on its way and it’s time to starting thinking about your garden. On this horticulture day edition of Talk of Iowa , host Charity Nebbe is joined by Aaron Steil, Assistant Director of Reiman Gardens, and Richard Jauron, Iowa State University Extension Horticulture Specialist. They talk about selecting seeds for your spring garden and give tips for how to transition your seedlings to the outdoors. Before going to buy seeds, Steil says it's important to come up with a specific plan and know where you're going to put each plant. Then, time your planting carefully so that your seedlings are ready to face the outdoors when the time comes. "If you start them too early they get lanky and tall and don't transplant so well," Steil says. Keep the soil warm, preferably between 70 and 75 degrees, and get your seedlings used to going outside in the week or two before you transplant them. A heating mat can help with soil warmth, or

Caring for Your Valentine's Day Blooms

Fri, 02/15/2019 - 12:23
More cut flowers are purchased on Valentine’s Day than on any other day of the year, in spite of the fact that the holiday falls in the dead of winter. On this Horticulture Day edition of Talk of Iowa , host Charity Nebbe talks to h orticulturists Richard Jauron and Cindy Haynes about how to get the most out of your cut flowers.

The first step for prolonging the life of your bouquets is to place them in an area of your house with enough light and warmth, such as a kitchen table or countertop. "Make sure you put them in a bright, well lit location away from a door or a window or even a vent so that they don't get too hot or too cold," Haynes says. If they're not yet in a vase, cut about an inch from the stems and get them into clean, room temperature water as soon as possible. Then, be sure to change the

How Native Plants Sustain our Ecosystems

Wed, 02/06/2019 - 16:01
A Lot of Iowans have been planting milkweed over the years in an effort to bring Monarch butterflies back from the brink, and there has been some success. But dramatic changes in the landscape due to large scale agriculture and our own personal landscapes have such an impact, that planting milkweed is just a drop in the bucket. On this episode of Talk of Iowa , Host Charity Nebbe talks with Doug Tallamy, a Professor of entomology and wildlife ecology at the University of Delaware, to learn about the landscapes we’ve created, what the cost may be to many species, and how each one of us can make a difference. The importance of native plants can be seen in the "food webs" of our local wildlife. If groups of insects can’t eat non-native plants, they can't transfer that energy through these food webs to birds or other insect predators. “All of these things are working together, you can’t take one group out and expect the whole to continue to function.” says Tallamy. There are many things

How Will Plants and Insects Fare After the Polar Vortex?

Fri, 02/01/2019 - 14:22
We’ve just endured a polar vortex, which brought wind chills approaching -60F to some parts of Iowa. As the state begins to defrost, i t would be nice to think this extreme cold could be a setback for some of our least favorite invasive insects — but will it impact our beloved plants, too? On this horticulture day edition of Talk of Iowa , host Charity Nebbe talks with entomologist Donald Lewis and horticulturists Richard Jauron and Chris Currey about whether the unusually chilly weather will impact plants and insects. Then, Currey shares tips for raising orchids in climate controlled homes. Unfortunately, the recent cold will not make any difference in insect populations when spring arrives. "I think there's a lot of wishful thinking," Lewis says. "Insects that live in freezing temperatures are adapted to survive those temperatures." However, insects traditionally have lower populations in spring than in fall, which is likely to be true again this year. In terms of plants, Jauron says
