Getting the Most Out of Your Late-Season Produce

Hort Day Podcast - 5 hours 36 min ago
With the changing leaves and the cooling temperatures, late season vegetables are ready for harvesting. Knowing when exactly to harvest specific vegetables is a problem for many people, but Iowa State University Extension specialist Linda Naeve has advice for those curious about winter squash. "Winter squash is interesting because it has a very firm skin, so when the fruit becomes full-sized, do the finger nail test. If you can't really penetrate the skin with force, it should be nice and firm. Also, on many winter squashes, that stem should be dried, fairly woody. The vine may be starting to die down, but not necessarily," Naeve says. "The best time to harvest winter squash is right before frost, and the reason I say that is, if the vines are still alive, the bugs, the insects, the beetles will move right near the squash. And if your vines are already died down, you might start to see that, so I'd get them out of the garden right away." On this Talk of Iowa, host Charity Nebbe speaks

Fixing Your Late-Summer Patchy Lawn

Hort Day Podcast - Wed, 09/06/2017 - 10:29
It can be very frustrating when the picturesque, cloudless blue summer sky is undercut by a patchy, dead-looking lawn. In these last days of summer, it's common to assume that a discolored lawn is dead, but Iowa State University Extension Turfgrass Specialist Adam Thoms recommends inspecting the lawn more closely before assuming anything. "One of the great things to do is to actually get out and pull on the lawn, especially if the grass is still yellow looking. If it pulls right out in big chunks in your hand, it's probably dead. If there's still some resistance, it's probably coming back," Thoms says. "With the rains we've had throughout Iowa the last couple weeks, most of the grass, if it's going to come back, is starting to green up. If it hasn't shown signs of life, it's probably dead." On this Talk of Iowa, host Charity Nebbe speaks with Adam Thoms and Iowa State University Extension Horticulture Specialist Richard Jauron about seeding, re-seeding, core aeration and other late

The Garden Benefits of the Praying Mantis

Hort Day Podcast - Wed, 09/06/2017 - 10:14
One of Iowa's largest and most recognizable insects is the Praying Mantis. Contrary to their predatory nature and creepy appearance, the Praying Mantis is actually beneficial to the garden, and according to Entomologist Donald Lewis, they can't really hurt you. "I was just checking to see how strong the grip was on the Praying Mantis' front legs, and got my fingertip into the jaw part of where the two pieces of the leg come together, and the spines actually broke the skin," Lewis says. "They're quite strong, and the spines are quite sharp. Whether there was a lasting effect, I lost a drop of blood for the benefit of scientific discovery, but it was no big deal." On this Talk of Iowa, host Charity Nebbe speaks with Donald Lewis and Iowa State University Extension Horticulturist Richard Jauron about the Praying Mantis' effect on the garden and its life cycle, and they also take questions from listeners.

Corpse Flower Opens, Smells A Bit More Like Garbage Than Rotting Flesh

Hort Day Podcast - Tue, 07/25/2017 - 11:41
To some visitors, the corpse flower smells more like garbage than rotting mammal. The rare Sumatran plant, also known as Titan arum, is believed to be the first corpse flower of this variety to bloom in Iowa. Titan arum was expected to blossom last week, but the Greater Des Moines Botanical Garden says scorching temperatures of high 90s likely delayed the plant’s unfurling. Cooler weather has arrived and the garden's staff says the corpse flower opened and began emitting its infamous stench sometime between 2:00 and 3:00 am on Tuesday. "It kind of comes in waves," explains the garden's curatorial horticulturist Derek Carwood. "This morning for example, we were doing interviewers. It would be fine and smell great just like the conservatory usually does. And then all of the sudden you’d hit that odor and it would, you know trash or diapers or rotten cabbage would come through. It hits you pretty hard." Titan arum evolved its redolent reek to attract carrion beetles for pollination.
