In this cozy late-fall episode, the Hort Culture team (Alexis, Jessica, and Ray) talk all about lifting, curing, dividing, and storing tender bulbs and tubers—especially dahlias, begonias, caladiums, gladiolus, cannas, elephant ears, and more.

The hosts begin by chatting about Kentucky’s unpredictable weather, winter chores, and even a tangent about hot chocolate “tea hacks,” before digging into the main topic: what to do with plants that can’t survive a Zone 6 winter in the ground.

They walk through the why and how of storing tubers successfully:

 * Prevent rot and prevent drying out—the two main goals.
 * Ideal storage temps: generally 40–50°F, with some exceptions like caladiums that prefer it warmer.
 * Curing time: often just a few days with good airflow, and you don’t need to overthink it.
 * Leave the soil on to avoid excess moisture and bacterial problems.
 * Check stored tubers monthly for rot, shriveling, or excess dryness.
 * Storage media options: pine shavings, vermiculite, peat moss (in drier spaces), perlite, and more.
 * Dividing dahlias: the trickiest—eyes form near the crown, not on the tuber body, and are easier to see when the clump is warm or beginning to sprout.
 * Tools they rely on: shovels, digging forks, loppers, snips, and sometimes saws for huge clumps like cannas.

They wrap up with discussion on microclimates, overwintering experiments, and the joys of having a cellar or basement that naturally works as an ideal root-cellar environment.

Overall, the episode is a friendly, practical deep-dive into helping gardeners confidently store their favorite tender ornamentals through winter—and maybe even multiply their stock through spring dividing.

Storing Tender Bulbs & Tubers for Winter

In this festive episode, the Hort Culture team explores the challenges and charm of growing Christmas trees in Kentucky with guest farmer John Bednarski. John shares his journey from direct-marketing beef to cultivating thousands of Christmas trees at Sherwood Acres Farm, describing the steep learning curve and family teamwork that go into the business.

Listeners get an inside look at what it takes to produce the perfect holiday tree—from irrigation and soil prep to shearing, shaping, and deer control. John explains why Canaan firs thrive best in Kentucky’s conditions, while other species like Norway spruce and concolor fir pose challenges. The discussion also highlights the Kentucky Christmas Tree Growers Association and the importance of mentorship for new growers.

The episode blends technical insight with nostalgia as the hosts recall childhood memories of choosing fresh-cut trees and emphasize how “choose-and-cut” farms keep holiday traditions—and agritourism—alive. John also shares details about his farm’s new gift shop, family-friendly activities, and plans for future wreath-making workshops.

Throughout, the hosts remind listeners that buying a real tree supports local farms and sustainable practices—and even gives those trees a second life as fish habitat after the holidays.

The Christmas Tree Industry in Kentucky

This episode of the Hort Culture podcast kicks off with a spirited, lighthearted debate among the hosts about the definition of "peak fall" and where the line between autumn and winter truly lies. Following this seasonal discussion, the episode features guest Daniel Wilson, Director of the University of Kentucky's Robinson Center, a unique facility in Eastern Kentucky that integrates extension, research, and student learning as a land-grant mission hub. Wilson discusses the center's critical role and the ongoing, intentional rebuilding efforts following the devastating July 2022 flood, which destroyed eight of the center's thirteen structures, with a grand opening for the new "campus feel" set for Spring 2026. Beyond its traditional agricultural studies on row crops, the center is crucial for regional horticulture and sustainable Appalachian land use, providing site-specific data and research on crops like mushrooms, ginseng, and elderberry. Wilson highlights the impactful Heirloom Seed Project, a post-flood effort where the center's horticulturalist grew specific heirloom beans on their hop trellises to harvest and return the seeds to families who had lost their multi-generational seed stock, directly linking the center's research to the region's heritage and recovery.

The Robinson Center: Land-Grant Mission in Action

In this fall-themed episode, hosts Alexis, Brett, Jessica, and Ray (the “Plant People”) celebrate the season with a mix of food talk, laughter, and horticultural insights. They kick things off sharing their favorite pumpkin-inspired treats— from homemade pumpkin bread to smoked butternut mac and cheese and even pumpkin tortilla chips.

The conversation transitions into the episode’s main topic: fall leaf color in Kentucky and beyond. The group discusses the science behind color change — how cool nights, warm days, and moderate moisture bring out the best reds, oranges, and yellows. Ray explains how a good growing season followed by a slightly dry fall concentrates sugars in leaves, leading to vibrant anthocyanin-driven reds. They also talk about the impact of Kentucky’s record-dry August, wondering how it might affect 2025’s color display.

Listeners learn about useful resources like the ExploreFall.com foliage map and Kentucky Tourism’s fall color tracker, which show when and where to find peak color. The hosts share personal sightings — from maples just beginning to turn to the rich reds of burning bush and sassafras — and discuss how elevation, frost timing, and species type influence local color patterns.

The team also dives into some fascinating plant physiology, explaining how the green pigment chlorophyll fades to reveal yellows and oranges already present in leaves, while reds form later from sugar accumulation. Their side conversation about variegation and plant adaptation connects the science of leaf color to everyday gardening.

The episode wraps up with everyone’s appreciation for leaf-peeping season, favorite scenic drives, and plans to visit Kentucky’s Red River Gorge and other colorful fall spots.
