Horticulturati: The Multilayered Magic of Sheet Mulch Mar 25, 2023

On this episode, we’re gettin’ down and dirty with sheet mulch. Sheet mulching is a no-till, no-dig gardening practice of removing unwanted vegetation and building fertile soil by layering organic matter and letting it compost in place. While the layers suppress weeds by blocking sunlight, subterranean soil biology goes to work to break down the layers into new soil. The beauty of this simple practice is that you can do it at any time of year with materials you have on hand (like cardboard, shredded paper, and leaves) or can source for free from local sources (arborist wood chips, coffee grounds, and spent mushroom substrate).

We discuss the reasons for sheet mulching, when and how to do it, and what to use. Then we dive into the corrugated controversy around cardboard and ponder the role of science in gardening.

Horticulturati: The Art of Graphics with Lisa Nunamaker and Amy Fedele Dec 23, 2022

In this roundtable, we talk about drafting and drawing with Lisa Nunamaker, of Paper Garden Workshop, and Amy Fedele, of Pretty Purple Door, two fabulous garden educators who offer online courses in landscape graphics. Leah took courses from both instructors this year -- Lisa's Garden Graphics Toolkit and Amy's Great at Procreate.

We discuss why the fundamentals of hand-drafting remain so valuable to the design process; the role of digital design programs like AutoCAD; and how tablet apps provide a new, hybrid avenue of digital hand-drafting.

Then we turn to to the subject of emotional baggage: Why is drawing so scary for so many adults? How can we gain confidence as creatives and develop our own unique visual style?

Mentioned in this episode: the tablet apps (Procreate, Adobe Fresco, Morpholio Trace, Concepts); The Creative Habit by Twila Tharp (2006).

Horticulturati: Thorny Common Names Nov 03, 2022

A rose by any other name would smell as sweet, but some of the common names we use for plants downright stink! In this episode, we're diving into problematic colloquial names. Some common names are geographically misleading (“Jerusalem artichoke”); others are xenophobic, racist, or antisemitic ("wandering Jew"); while still others are an unfortunate combination of both (“Turk’s cap”).

While it's probably too much to expect everyone to start using Latin names for plants, we can adapt new common names that are more culturally sensitive and accurate. Like the plants themselves, common names are organic, living things that need to evolve over time.

First up, some armadillo drama and an update on Colleen's super-low-maintenance front yard renovation inspired by the writing of Roy Diblik (here's our original episode about that.)

Mentioned:

Great at Procreate, an online digital drawing course from instructor Amy Fedele; "Problematic Common Names" (House Plant Hobbyist, 2021); How Plants Get Their Names by L.H. Bailey (Macmillian, 1933); Native Flora of Texas by the Texas Highway Department (undated, ca. 1960); The Better Common Names Project of the Entomological Society of America; and Potentially Problematic Common Names, a study by the American Public Gardens Association (2021).

Horticulturati: Humble History of the Flowerpot Sep 03, 2022

In this episode, Colleen unearths as much as she can about the largely unwritten history of plant pots.

When did humans start growing plants in containers?

How did innovations in materials and technology lead to the domestication of plants, plant collecting, and the growth of the nursery industry?

Why are plant pots so overlooked as a facet of industrial design? (We can rattle off several iconic chair designs, but flowerpots? Not so much.)

Why don’t the standardized names of nursery pot sizes correspond to their actual volume in the US?

We have more questions than answers, folks.

First up, Leah is practicing her drawings. And we need an alternative name for the tricky season that comes between summer and fall in Texas.

Horticulturati: The Full Monty Don Aug 05, 2022

We're back with a salute to Monty Don, beloved British gardening expert, author, and fashion icon, whose infectious passion for plants is boosting our spirits through this bummer summer.

Though little known in the US, jaunty Monty is a big celebrity across the pond, as the host of the BBC's Gardener's World, Big Dreams, Small Spaces, and Around The World in 80 Gardens. With his soothing temperament and sharp insights, he's a bit like a cross between Anthony Bourdain and Mr Rogers.

We discuss differing approaches to horticulture and land stewardship in the US and the UK and how Big Dreams, Small Spaces has informed our thinking about the role of the landscape designer as consultant. Then we follow Monty's 80 Gardens journey to Mexico City to visit perhaps the oldest perennial flowering gardens in the world: the floating chinampas of Xochimilco.

(Where to watch these shows in the US? Gardener's World and Big Dreams are currently available on Amazon Prime. The full 80 Gardens series is on Youtube.)

Horticulturati: Conservation Design Jun 12, 2022

On this episode, we dive into ecologist Douglas Tallamy's books Nature's Best Hope (2019) and The Living Landscape (2014, with Rick Darke). Tallamy's work takes native plant gardening and wildlife gardening to another level by focusing not just on species diversity, but on diversity of species interaction to promote ecological conservation. According to Tallamy, "native" plants are those which have "evolved in a given place over a period of time sufficient to develop complex and essential relationships with a diversity of animals." Native plants, then, are organisms that have interacted with insects, birds, and mammals for thousands, if not millions, of years. We discuss Tallamy's perspective and the how we might tackle the challenge of implementing a conservation design -- and convincing homeowners to think of themselves as land stewards.

Up first: It's hot here in Austin, so we are talking about what early triple-digit temps mean for gardeners. Leah is looking for her niche, taking inspiration from specialist insects.

Horticulturati: Pocket Prairies with John Hart Asher May 14, 2022

We sat down at the picnic table with John Hart Asher, host of Central Texas Gardener and Cofounder/Senior Environmental Designer at Blackland Collaborative to talk about pocket prairies. What’s a pocket prairie? It’s a very small prairie. What’s a prairie? It’s a community of native grasses and forbs wildflowers that have evolved along with microbes, plants, and animals over millennia. This "disturbance-driven ecology" historically relied on periodic fire and low-frequency, high-intensity grazing to function. John Hart sees the "millions-year-old technology" of the American prairie as a replicable system that we can borrow in our own yards to sequester carbon, manage stormwater runoff, and support the essential interconnections between life forms that make up the food-soil web. As Douglas Tallamy writes in his book Nature's Best Hope, "If each American landowner made it a goal to convert half of his or her lawn to native plant communities...[we] could collectively restore some semblance of ecosystem function to more than twenty million acres of what is now ecological wasteland."

We discuss the role of wildfires and buffalo grazing in Texas before European settlement, the Lady Bird Johnson Wildflower Center's research on prescribed burning, and how to prepare, install, and maintain a pocket prairie.

John Hart insists that we must rethink our approach to landscape design, gardening, land ownership, and even our concept of "nature" if we are to sustain life on earth. He describes prairie restoration as "a trajectory, not an intervention" -- a process, rather than a product -- which can help us reconnect with the web of life, reduce climate anxiety, and make our homes more beautiful to boot.

Horticulturati: Designing for Maintenance & "The Soul of a Farmer" Jan 07, 2022

Happy New Year! We’re back from vacation with a discussion of a book that is very much in the Horticulturati wheelhouse, The Know Maintenance Perennial Garden. Author Roy Diblik, a Wisconsin-based designer and plantsman, argues that anyone can build a “design-magazine-worthy garden at home” by thoughtfully combining perennials to form functional plant communities that need little more than an annual mow – almost no irrigation, mulch, or hand-pruning required. This low-maintenance method could be a revelation for residential and commercial landscapes alike, but can it work in Texas, with our balmy winters and scorching summers? Is there a way to implement the mowing-for-maintenance concept using electric, rather than gas, machines? Colleen is inspired to experiment as she redesigns her front yard.

Next, we review a documentary short, The Soul of a Farmer, by filmmaker Roger Sherman. Chef-turned-grower Patty Gentry of Early Girl Farm rents three acres in Long Island from Isabella Rosselini (!!!), who calls Patty “the Picasso of Vegetables.” Sidestepping many of the tropes of farm-to-table docs (Gentry admits she’d probably be living out of her truck if it weren’t for her spouse’s financial support) this film paints an honest portrait of the struggles and small victories of one artisanal vegetable grower as she transitions from wholesale growing for restaurants to a Community Supported Agriculture (CSA) model. Food porn ahead!

Horticulturati: Growing a Vision with Barton Springs Nursery Nov 30, 2021

If you have a passion for plants, you probably love plant shopping. Our local garden centers are more than just a place to source nursery stock; they’re a designer’s trove of botanical information and inspiration. After untold hours spent perusing the grounds of Barton Springs Nursery, we finally sat down for a chat with two of the new owners, designer Amy Hovis and horticulturist Willy Glenn.

Founded in 1986 by Bernardine and Conrad Bering, Barton Springs Nursery is an Austin institution. Into a drab '80s landscape of photinias, nandinas, and boxwoods, the Berings introduced wild plants from seed and cuttings -- salvias, mallows, bunchgrasses, and palms -- and helped to pioneer the city's vibrant gardening scene with an emphasis on sustainability, native plants, and local expertise. After 35 years, the Berings retired in January 2021 and sold the store to Hovis, the owner of Eden Garden Design; Glenn, the former manager of the nursery; and Greg Thomas. Since then, they've added an event space, revamped the grounds, and adopted two new mascots: a kitten named Fern, and a tortoise named Fig.

Hovis and Glenn say their goal is to make the "new" BSN the best nursery in Texas (at the very least). We talked about new propagation experiments coming down the pike, the catastrophic winter storm in February, and how the pandemic has ushered in an unexpected gardening renaissance.

Horticulturati: Garden Design Part II Oct 29, 2021

A year ago, we recorded a long and rambly episode on garden design. Now we're making it an October tradition! Revisiting the subject, we realize our approaches to design have changed, but we're still hell-bent on questioning basic tenets. How important is color? Are foundation shrubs necessary? Should we flip the script on "seasonal interest?" Does "timesharing with plants" really work? Join us at the picnic table as we parse out some jargon (form, texture, verticality), swap tips, and get hangry for cookies.

Horticulturati: Dividing & Multiplying Plants Oct 04, 2021

When you have too many plants, it's time to make more! That's gardener logic for you. Fall is a great time to divide perennials and save seeds - but how? We dig into these methods of backyard propagation and again give you permission to be ruthless and/or lazy in the garden. Go ham on that root ball! Let the veggies bolt! Plants can handle it. Up first: Leah has a design question and Colleen scours the streaming platforms for Monty Don.

Horticulturati: Cleveland and the Cuyahoga River Fires Sep 02, 2021

Fresh off a hometown visit to Cleveland, Colleen brings us the story of the Cuyahoga: a river once so polluted with industrial sludge, it burned. At least thirteen times. While the largest and most damaging conflagration occurred in 1952, it was the 1969 river fire that made national headlines, thanks to Mayor Carl Stokes. As one of the first Black mayors of a major American city, the charismatic and media-savvy Stokes connected the dots between economic inequality and environmental degradation, and advocated on the national stage for legislation that would clean up the “urban environment,” starting with the Cuyahoga and Lake Erie. Today, the pristine Cuyahoga is a symbol of pride for Clevelanders, yet this civic success story belies the reality of ongoing inequality there. Colleen shares her personal history of growing up in “a city with no superlatives,” her own chance connection to Stokes, and how she’s begun parsing the difference between “environmentalism” and “environmental justice.”

Also, Leah shares an update on the so-called Mystery Seeds from China.

Horticulturati: A Gardener's Guide to Honeybees (Part 2) Aug 17, 2021

At long last, here's the second installment of our bee-stravaganza! Leah interviews beekeeper Tara Chapman, owner of Two Hives Honey, about the intricate connection between bees, plants, and weather. Then, your hosts discuss how to be a good steward to honeybees--and native bees and other pollinators as well. Even if you're not a beekeeper, there are many things you can do (or not do) to be a friend to the bees!

Horticulturati: Gardener's Guide to Honeybees (Part I of II) Jul 19, 2021

Enter the hive with us for another classic critter topic: BEES! We recorded so much on bees that we have to split this bee-nanza into a two-parter! In part one, Leah suits up for a tour at Two Hives Honey in Manor, Texas, and investigates honeybee ecology. In part two, we’ll focus on how, as a gardener, you can support our honey-making friends (along with native bees and other pollinators).

What are honeybees? Why do they live in boxes? And how did Apis mellifera, just one of tens of thousands of bee species in the world, become so ubiquitous in our gardens? We’ll answer these questions and more with the help of professional beekeeper Samantha Dula.

Mentioned in this episode:

Beyond Permaculture with Cassiopeia Farm Jun 03, 2021

Welcome to Hothouse Season 2! If you follow any flower farmers on Instagram, the romance may be all too tempting: picture yourself quitting the city, fixing up an old farmhouse, and spending your days harvesting flowers and arranging bouquets on a ten-acre homestead. Now imagine doing that in a fire-prone, flood-prone, deer-pressured, rapidly developing portion of Austin without access to well water or an agricultural property tax exemption. Sam Eberhardt and Dan Poole are farming on the razor’s edge, doing everything the hard way, and still somehow managing to make the dream look absolutely fabulous.

In this episode, we take a walk behind the scenes of Cassiopeia, a flower farm and orchard dedicated to ethical land stewardship, wildlife conservation, and “beyond organic” principles. Sam and Dan discuss the structural obstacles faced by small farms, their commitment to regenerative agriculture, and their “shotgun approach” to rolling with the punches of climate change.

Check out Cassiopeia Farm's farm-to-table CSA, the Best Buds Club, find their flowers at Austin Flower Company, Salt and Time, and Confituras, and follow them on Instagram.

Horticulturati: Thawing Out Mar 02, 2021

On this Horticulturati, we return from hiatus with tales of the Snowpocalypse -- or Snowmageddon, Snowvid, whatever you want to call it -- to document the record-breaking winter weather that broke Texas' electric grid and ushered in a scary new climate reality for the plants and people of the Lone Star State. Your hosts discuss personal trauma, a jumble of conflicting post-freeze plant advice, and a bunch of anecdotes about what worked and what didn't in preparing our gardens and ourselves for an unprecedented 144 consecutive hours of below-freezing temps in Austin.

Horticulturati: Garden Design Oct 07, 2020

On this mega-episode of the Horticulturati, we’re tackling garden design--our approaches, our anxieties, and our gripes about “expert” sources of mystifying advice and misleading photography. Garden design books are rife with the jargon of art theory. How well does this translate to the living medium of plants in the landscape? Google Image Search puts pictures of every plant imaginable at our fingertips, which is great...but also not so great. Hashing it out at length, we agree on some basic aesthetic tenets, then throw the rest out the window. Maybe it all comes down to climate, maintenance, and solving problems with plants. First up, Leah describes a real-life botanical nightmare that sends her down memory lane. Last, Colleen shares a listener letter from a Buckeye gardening in the southwest.

The Horticulturati: Armadillos! Aug 23, 2020

Turtle rabbit. Shell possum. Roadkill. Whatever you call it, the nine-banded armadillo is a mysterious, ancient, and unfairly maligned mammal. Find out everything you ever wanted to know (and more) about this Texas icon. Leah traces the armadillo’s bizarre migratory history, its role in medical research, and its rise as a symbol of the Austin music scene. We’ll bust some armadillo myths, meet some famous champions (including naturalist Roy Bedichek and artist Jim Franklin) and discuss the intractable problem of armadillos in the garden. So, spark up a spliff and fill your pantyhose with worms! The next time one wreaks havoc on your flowerbeds, you may just have a little more appreciation for this humble critter.

Hothouse is returning from hiatus! From here on out this podcast feed will be all Hothouse, so if you want to keep hearing The Horticulturati, please subscribe to that feed HERE (for Apple Podcasts) or HERE (for Spotify).

Crape myrtles are blooming all over the place and Leah is DISGUSTED. What’s triggering this Lagerstroemiaphobia? Perhaps it's not about the crape myrtles at all, but rather the lingering demons of her past in exurban hell. Next, Colleen reports on a storied gourd that vine borers can’t touch: the cushaw squash. Domesticated some time around the dawn of agriculture, the obscure cushaw took on special significance to African American foodways as a “slave food” staple. We discuss plants and memory, the merits of “folklore,” and the importance of heirloom seeds as “living archives” of cultural information. Happy belated Juneteenth!

Houseplant Confidential with Jane Perrone Nov 15, 2018

On this episode, we’re taking an intimate look at the the most domesticated plants of all: houseplants. My guest, Jane Perrone, is a London-based journalist and the host-producer of the indoor gardening podcast On The Ledge. We’ll discuss Jane’s background, some myths and misconceptions of container gardening, and the human tendency to anthropomorphize our houseplants. At the top of the show, I’ll dive into the revealing history of the Aspidistra elatior, a houseplant once so iconic it was the subject of a popular song, the codename for a “black propaganda” operation in WWII, and the central metaphor in a George Orwell novel. Today, the Aspidistra is barely considered a houseplant at all. Can this casualty of fashion ever come back in style?

Nothing Natural About Capitalism (Part 2 of 2) with Ryan Rosshirt Sep 17, 2018

In Part 2 of the series “Nothing Natural About Capitalism,” Leah talks to Austin-based activist Ryan Rosshirt about permaculture design and the challenge of building a society that supports meaningful work. Like so many Americans, Ryan was jolted into political action by the rise of Donald Trump. He quit his desk job before the 2016 election to focus full-time on canvassing for social justice and environmentalist issues. At the same time, he discovered a passion for gardening; a small vegetable patch grew into the backyard microfarm where he’s producing a lot of his own food today. On this episode, Ryan talks about implementing permaculture principles to repair the ecosystem in his backyard. Also, he and Leah discuss the idea of “vocations,” the structural barriers imposed by capitalism that prevent people from enjoying meaningful work, and how the Austin chapter of the Democratic Socialists of America (DSA) is fighting business interests big and small to improve quality of life for workers.

Nothing Natural About Capitalism (Part 1 of 2) Aug 22, 2018

Capitalism: Can't live with it, can't live without it! Or can we? And what is the connection between capitalism and what we eat, how we work, and who bears the impacts of climate change? For a lot of us, the ecological consequences of our economic system are clear: factory farming, algae blooms, pollinator decline, and the Trump Administration's evisceration of the EPA. What, if any, are the alternatives?

In this two-part series, "Nothing Natural About Capitalism," the Starship Hothouse will boldly go where no gardening podcast has gone before, as Leah attempts to articulate some nascent ideas about how the design principles of permaculture, combined with the populist vision of the Democratic Socialists of America (DSA), might offer a ray of hope in these dispiriting times. In Part 1, Mike Moody, co-host of the Star Trek Discovery Pod (and the engineer of this show) interviews Leah about how she envisions a path between democratic socialism and environmentalism.

Also, Leah tracks down one of her podcasting heroes, Chenjerai Kumanyika, co-host of Gimlet's Uncivil, at the Podcast Movement Conference in Philadelphia. Kumanyika explains that capitalism is not just an economic system; it's a mindset, and he offers insight into why we are having these discussions right now.

In Part 2, Leah interviews activist and permaculture designer Ryan Rosshirt about why he joined the DSA, how he turned his backyard into a permaculture farm, how what civic engagement can improve our quality of life. From Co-ops, to city council meetings, to the joy of chickens, we're covering a lot of ground here, so bear with us!

Conservation & Identity | Park Ranger LaJuan Tucker Jul 07, 2018

On this episode, we'll examine the relationship between natural history and social history. Join Leah as she sits down with park ranger LaJuan Tucker to talk about the conservation of urban wildlife, and how changing societal attitudes determine how we relate to our landscapes. LaJuan will explain how, in recent years, Austin's Parks and Recreation Department has implemented a new mandate to protect pollinator habitats, even when that means sacrificing the "manicured" look of the park in high-traffic areas.

We'll also zoom out and talk more broadly about the philosophy of conservation today. How should our parklands be used, and who gets to decide? Should we strive to preserve "native" landscapes, or build more community gardens? And how do we reconcile the romance of the Texas landscape with the racist realities of our past? We'll talk about the lingering effects of Jim Crow in Austin, from actual monuments to the Confederacy, to present-day structural inequality. And we'll hear about LaJuan's personal mission to encourage more young Austinites of color to seek careers in environmental conservation and city planning. Here, and in upcoming episodes as well, we'll begin to engage with the paradox of Austin as an environmentally progressive, yet socioeconomically segregated, city.
