Squash, Sweet Potatos, and More for Your Late Season Harvest

Hort Day Podcast - Fri, 09/28/2018 - 15:29
With the changing leaves and the cooling temperatures, it’s time to start harvesting late season produce. It can be difficult to know when to harvest crops like sweet potatoes and winter squash, but Iowa State University Horticulturist Ajay Nair recommends paying close attention to the recommended harvest dates when you plant. He also says it’s very important to prepare your produce for storage. "If you want to store sweet potatoes for longer term storage… you need to start thinking about curing them. When you harvest you want to make sure you remove all the dirt and after that you put them in a room or expose them to conditions where the temperatures are 80-85 degrees Fahrenheit and maintain an 80-90 percent humidity. If we can keep those two conditions for 7 -10 days the sweet potatoes will be cured," Nair says. Nair says it’s also important to cure winter squash before storage, but they can be cured at a lower temperature of 65-70 degrees Fahrenheit. On this Talk of Iowa, host

For Late Season Additions to Your Garden, Consider These Fun Fruits

Hort Day Podcast - Fri, 09/21/2018 - 12:49
The end of the growing season is in sight, but there's still time to add more plants to your landscape! On this edition of Talk of Iowa , host Charity Nebbe talks with Aaron Steil, Assistant Director of Reiman Gardens in Ames, and Patrick O'Malley, Iowa State University Extension Horticulture Specialist , about late season planting and unusual fruit crops. We usually think of spring when we think of adding new foliage to our gardens, but there are a number of factors that make fall a great time of year for planting, too. "This time of year the soils are a lot warmer, so you can get a lot better establishment of new growth after you've planted," Steil says. "It's also a good time of year because the soil moisture and weather conditions are more favorable." Pawpaw, persimmon, honeyberry, and other niche fruit bearing plants might not yet be on your radar, but can make excellent additions to many Iowa gardens. While delicate fruit trees like peaches and apples do best planted in spring, O

Identifying Stressed Out Trees

Hort Day Podcast - Fri, 09/07/2018 - 14:01
This summer we’ve seen below average temperatures, above average temperatures, very dry conditions, and flooding. The weather has been stressing a lot of people out and it’s taken a toll on some trees. On this Horticulture Day edition of Talk of Iowa , host Charity Nebbe talks to Jeff Iles, professor and chair of the Horticulture Department at Iowa State University, and Mark Vistosh, DNR forester, about how to identify when your trees might be struggling. Vitosh says that most trees probably aren't showing signs of stress just yet: it takes about a year for trees to reflect conditions from the previous season. "If it grew [well] this year, it had a good growing season last year," he says. Next year, however, you're likely to see the impacts of this summer's unpredictable weather. "Trees remember," Vitosh says. "If they're working hard to replace what they had before, they're stressed." A more immediate concern is the impact of flooding, which can weaken roots and down otherwise healthy

Late Summer Lawn Care

Hort Day Podcast - Fri, 08/24/2018 - 15:57
If you’ve been struggling with a patchy lawn all summer, the time to act is now. On this Horticulture Day edition of Talk of Iowa , host Charity Nebbe talks with Iowa State University Extension turf grass specialist Adam Thoms about seeding, re-seeding, core aeration, and other late summer tasks. Thoms says that Mid-August through mid-September is the ideal time to seed your lawn because the fall weather makes it hard for weeds to germinate. "With the cooler nights, crabgrass is slowing down," Thoms says. Before seeding, be sure to aerate using either a machine or handheld aerator. Then, between now and September 15th, Thoms recommends fertilizing your freshly seeded lawn to keep it well-nourished. "The best defense against weeds is a healthy yard." Later in the hour, Iowa State University Extension Horticulture Specialist Richard Jauron joins Thoms to answer listener questions.
