Purple Planted Majesties for Your Garden

Mon, 04/09/2018 - 11:16
Purple foliage is striking against a landscape of green, pops against neutral-colored siding, and can add color to a garden year-round. For Cindy Haynes, associate professor of horticulture at Iowa State University, a plum tree planted her passion for the purple pigment, and her garden hasn't been the same since. "You don't want an all purple foliage garden because then nothing stands out," Haynes says. "I've tried it, I know." On this Talk of Iowa , Haynes joins Charity Nebbe for this week's horticulture day. Haynes recommends a variety of shrubs, flowering plants, and trees to add to your garden. Ninebarks, little devils, coleus, black snakeroot, royal raindrops, prairie fire, and Norway maples are just a few options to bring violets and burgundies into your life. Richard Jauron, Iowa State University Extension horticulture specialist, also joins Haynes as they answer listener questions.

Planting a New Tree? Here's What to Consider

Fri, 03/16/2018 - 13:16
There are many things to consider when adding shade to your yard in the form of a tree, and it can be difficult to know where to start. On this edition of Talk of Iowa , guest host Jason Burns talks with Iowa State University horticulturists Jeff Iles and Richard Jauron about what to keep in mind when buying and planting a sapling. “The months of April and May are great months to plant,” says Iles. Though he tends to rely more on soil conditions than the time of year when deciding when to plant. “I don’t want to be digging in the soil when it’s exceptionally wet, so I usually wait for it to dry out somewhat.” He adds that planting season depends on the type of sapling you buy. Bare root nursery stock trees are sold without soil. “Typically, the bare root season is really early,” he says. “April is a good time to plant care root nursery stock.” Iles says to look for three main things when picking out your new tree. “I like to see trees with a nice strong central leader, good branching,

Warmth and Moisture Crucial to Spring Seed Germination

Fri, 03/02/2018 - 13:07
On this Talk of Iowa , Charity Nebbe talks with Linda Naeve, ISU Extension Value Added Agriculture Program Specialist, about taking our seed starting skills to the next level. It helps to start with the right medium. "We recommend you go to the garden center and invest in a seed-starting mix," Naeve says. "A soil-less media that contains peat, perhaps vermiculite, very fine medium. That medium drains well." "Don't fill your packs of your starting container with the medium and then sow the seeds, because the medium is always very dry when it comes," Naeve says. "The best thing to do is wet it ahead of time before you sow the seed." Naeve and Richard Jauron, ISU Extension Horticulture Specialist, talk about different kinds of soil mixes, containers, heating mats, and lights. They also answer listeners' questions about plants and trees.

Valentine's Day Flower Care

Fri, 02/02/2018 - 13:00
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. When buying a bouquet, it can be hard to determine how best to care for cut flowers and make them last. Cindy Haynes, a horticulturalist from Iowa State University, has some tips for selecting cut flowers. “We like roses that are fairly tight in bud that are showing good color,” Haynes says. “Red roses and some of the darker colored roses don’t show that damage quite as much as something like a white rose.” Care should be taken when selecting dyed flowers. “The addition of the dye, particularly for the roses, might shorten the life expectancy a little bit,” Haynes says. On this Talk of Iowa, host Charity Nebbe speaks with Haynes and Iowa State University horticulturalist Richard Jauron about getting the most out of cut flowers any day of the year, judging a bouquet, and extending a flower's life expectancy.

New Year's Resolutions for Your Garden

Fri, 01/05/2018 - 13:21
The harsh winter weather is upon us this January, and many Iowans are left longingly looking at their outdoor gardens buried in snow wondering what they can do to stay busy during the winter months. While some may opt to visit Iowa's many wonderful indoor botanical gardens, another option is to create a similar atmosphere within your own home. Assistant director of Reiman Gardens, Aaron Steil, has suggestions how to create a humid atmosphere for plants to grow. "One of the big challenges at home is humidity," Steil says. "The way we heat our homes dries the air out, and the air this time of year naturally has a lot less moisture in it. If you can figure out how to add humidity to the home, and spraying water in the air doesn't work; you need to use a humidifier, then that's the hardest part." On this Talk of Iowa, host Charity Nebbe speaks with Steil and Iowa State University Extension Horticulture Specialist Richard Jauron about indoor botanical gardens in the area, their own New Year
