12 Gifts from the Heart for Gardeners
Steve and Emma wrap up the 2021 podcasting season with ways to give to the gardeners in your life.
Passive Solar Greenhouses with Rob Avis
Rob Avis from Verge Permaculture talks about passive solar greenhouses.
Rob Avis from Verge Permaculture shares tips on passive solar greenhouses.
Balance
Avis says a key consideration when designing a passive solar greenhouse is whether to optimize the design for light or for thermal efficiency. He says it’s a trade off between light and heat.
Knowing the balance between light and heat will help inform design choices such as glazing material and the amount of glazing surface.
Incredible Edible: Pamela Warhurst on Making Grey Spaces Green
Pamela Warhurst talks about planting propaganda veg gardens and building community. Warhurst helped found the Incredible Edible Network
From the Ground Up
Pamela Warhurst from the Incredible Edible Network talks about turning grey spaces green by helping people believe in themselves.
The original Incredible Edible project in her hometown started with “propaganda” gardens on public land. It evolved to include edible plants around the community health centre and collaborations with businesses in the community.
Today the Incredible Edible Network includes communities around the world.
“It wasn’t the veg that mattered: It was the fact that a bunch of people had said, ‘We’re going to change things.’”
Top Tips
Warhust says to start by helping peole to help themselves.
Here are her top two tips to get started:
Just get up and do it. Don’t make a long list.
Believe in yourself.
“It’s a movement of people who care about tomorrow as well as today.”
Making Change One Garden at a Time
Emily Murphy talks about gardening for community, health, and the environment; and Sunday Harrison talks about making change through urban school gardens.
Grow Now
Emily Murphy believes individual gardeners doing small things can add up to big change.
Murphy is a garden designer, educator, and author with a background that includes botany, ethnobotany, environmental science, and ecology. It gives her a unique vantage point to teach people about gardening and the environment.
Murphy is the creator of the website passthepistil.com, and author of Grow What You Love, 12 Food Plant Families to Change Your Life.
She shares ideas from her new book is Grow Now: How we can save our health, communities, and plant – one garden at a time. In it, Murphy looks at how individual gardeners can make change positive change in the world.
Green Thumbs Growing Kids
Sunday Harrison gets city kids gardening. She’s with Green Thumbs Growing Kids, which gives hands-on garden and food education to urban school kids.
Along with school gardens, she talks about microgreens, a fast maturing crop for kids. And a new project is kids growing trees from seed — trees that will line Toronto streets.
Since Harrison joined us on the show a year ago to talk about school gardens, demand for school gardens has been huge.
Food-Focused Homestead Life
Gary Dickenson talks about his move from the UK to a remove homestead in northern Latvia.
Have you ever thought of changing your relationship with food?
Gary Dickenson put food front and centre in his new life as a homesteader. He tells us about his move from a seaside town in the UK, where he worked in marketing, to a remote corner of northern Latvia.
Dickenson says that the thing he best likes about homesteading life is the freedom it offers him.
Busy Homestead
It’s a busy homestead. Projects include:
Greenhouses
Smoking food
Canning
Wood heating
Maple syrup
Hugelkultur
No-Till veg plots
Thinking of Homesteading?
Here are Dickenson’s tips:
Before you make the leap, spend time on a homestead
Look ahead 10 years to think about where you want to be
Don’t buy into the romanticism of a homestead because it’s hard work
Plan, but let plans change
Act like a child and ask “why?”
Experiment and celebrate both success and failures
Build a network of friends for support

School Food Gardens Open Career Horizons
Allison Eady from Waterloo Region School Food Gardens talks about garden-based learning and introducing students to the food system
Garden-based learning: Growing seeds, growing communication skills, opening career horizons.
The Wateroo Region School Food Gardens project has built 35 school gardens, touching 20,000 students in this region of Ontario.
Allison Eady, program co-ordinator, explains that it provides information and curriculum ideas to educators, grants for school gardens, and direct programming for youth.
Garden-Based Learning
Eady sees school gardens as an opportunity for teaching more than gardening. She says garden-based lessons can be used for many subjects, including art, math, and science.
Launch a School Garden
“The best chance for success is when there’s a network of people who support it,” says Eady as she talks about successful school gardens.
She says it’s important to find allies in the community, whether it’s organizations or community members. That’s because school populations change fairly quickly: kids (and parents) move on, and staff are shuffled between schools. That makes the stability of community support important for the long-term success of a school garden.
Eady says not to worry about being a garden expert when starting a school garden. “It’s about figuring it all out together,” she says.
Youth Programming
During the COVID pandemic Waterloo Region School Gardens has pivoted to provide more direct programming for youth, including career mentorship and student-run markets.
Another initiative helps youth explore food-related topics of interest to them. Youth research a topic, and then create blog posts or videos to teach other youth, with the support of program staff. The video below is an example.
Virtual Apple Tasting
Susan Poizner talks about the virtual apple tasting she recently held to raise money for her community orchard.
Stop and smell the roses? Community event helps people to stop and smell…apples.
Susan Poizner recently helped 50 Torontonians to stop and smell…apples. Poizner, a fruit-tree-care educator and college instructor with a passion for growing fruit trees, organized a virtual apple-tasting event as a fundraiser for her local community orchard.
Virtual Apple-Tasting Event
Poizner visited an orchard specializing in heirloom apple varieties to get enough apples for 50 participants.
Participants received a paper bag containing the six apple varieties for the tasting. Each was marked with coloured stickers for identification.
To help participants think about what they were tasting, the event was facilitated by an apple sommelier, a researcher specializing in taste perception.
Poizner explains that researchers testing new apple varieties for consumer acceptance might consider upwards of 50 things.
For this event, participants were asked to share feedback on four things:
Overall apple intensity
Honey
Floral
Green-Herbaceous

Grow Quince and Garden Journal
Nan Stefanik talks about growing quince. Helen Battersby talks about the Toronto & Golden Horseshoe Gardener’s Journal
Grow Quince in Cold Climates
Imagine a job that revolved around a plant you’re passionate about. What plant would it be for you?
For Nan Stefanik that plant is quince.
She first tasted quince as an adult, on an overseas trip. After returning home, she was surprised to learn it grew locally in New England.
With a long history of its cultivation in New England, knowledge of quince had receded over time.
#GrowQuince
Stefanik’s business, Vermont Quince, makes quince paste, quince preserves, and other specialty quince products using New-England-grown quince.
Along with food products, she has made it her mission to collect and share quince information.
Using a specialty-crop grant, she started a #GrowQuince campaign to share quince-growing information.
Find more information about how to grow and how to cook quince on the Vermont Quince website.
What’s next? Stefanik and her son have acquired land for a quince education centre where they can combine a shop, demonstrations, and hold scion exchanges.
Toronto & Golden Horseshoe Gardener’s Journal
Our second guest today is also passionate about what she does. Helen Battersby produces the Toronto and Golden Horseshoe Gardener’s Journal.
This year marks the 30th anniversary of the journal, which includes information about frost dates, seed-starting dates, plant and seed sources — and also has space to record garden successes and failures.
There’s a deeply human story behind the journal, the story of a mother helping a son. Battersby shares that story, and talks about what’s new in the 2022 edition.
Compost Heater Heats a Hot Tub
Tom Bartels heats a hot tub and feeds his garden with wood-chip compost.
A wood-chip compost pile steams up this hot tub.
Today we visit a Colorado garden at an elevation of 6,500 feet. This episode co-hosted by Ryan Cullen, farmer at City of Greens.
Tom Bartels harvests 1,000 pound of fresh produce a year from his 1,300-square-foot garden, even though he has only 130 growing days.
Bartels uses a large amount of compost in his garden to maintain healthy soil. Much of that compost comes from wood chips.
But wood chips do more than feed his soil: They generate heat as they decompose. He can heat an outdoor hot tub through two Colorado winters with a pile of wood chips. No combustion is needed.
Heat from Wood Chips
Bartels says that many arborists pay to discard wood chips. By composting them, he removes them from the waste stream and gets both heat and compost for free.
The wood-chip pile used to heat the hot tub is approximately 6 feet tall and 12 feet in diameter. As he builds the pile, Bartels wets the wood chips and coils plastic piping within the pile.
The added moisture makes conditions suitable to microbial growth, while the water-filled plastic piping collects heat generated within the pile as microbes break down the wood chips.
Over two winters, the decomposing pile of wood chips generates the heat equivalent of burning 7 cords of wood. The temperature inside the pile gets as high as 150°F, and it stays warm enough to heat the hot tub for about 18 months.
From Heater to Compost
As microbial action slows down and the temperature within the pile drops, Bartels adds worms to speed up the composting process.
After another two or three months, the wood chips have been transformed into finished compost—worm castings—ready for the garden.
The wood chips that heated the hot tub for two winters are turned into 50 wheelbarrow loads of worm castings.
Tips for Wood-Chip Heating
Bartels explains that the right mix of wood chips makes the process work better. A blend of chipped coniferous wood as well as chipped small-diameter deciduous branches is ideal. This is because the small-diameter deciduous branches container more nitrogen—giving a ratio of carbon to nitrogen conducive to heat generation.
Here are Bartels’ wood-chip heating tips:
Have enough nitrogen in the pile. To be safe and make sure there’s enough nitrogen within the pile to give him good heat generation, Bartels says he adds about 5 per cent sheep manure. He also adds sawdust, which, he eplains, acts as a “bridge fuel” while the breakdown of the chips gets underway.
Have enough moisture in the pile. Bartels estimates that there are 4,000 gallons of water suspended within the pile. That’s a good thing because moisture is needed for optimal microbial activity. To keep moisture levels high, Bartels leaves the wood chips uncovered for the entire 18 months, allowing rain and snow to replenish moisture levels.
Greenhouse Wood-Chip Heating
Bartels sees opportunity for this sort of system beyond his demonstration hot tub.
He says that such systems are currently used to heat greenhouses and radiant floor heating systems.
Interviews
Grow Bamboo in Cold Climates
Bamboo expert Fred Hornaday on bamboo for cold climates.
Fred Hornaday is bullish about bamboo and it’s many uses. From fuel to food to fibre, he sees it as a versatile crop with environmental benefits.
He shares his passion for bamboo through his bambubatu website, which has information about bamboo, how to grow it, how to use it, and its lore.
Many Uses of Bamboo
Bamboo is an extremely versatile crop that be be made into:
fabric
flooring
fuel
paper
food
mats
cutting boards
Bamboo in Cold Climates
There are many types of bamboo that survive in cold climates. Many of these cold-hardy bamboos are in the gemus Phyllostachys or Fargesia.
Bamboos in the former are “running” bamboos. Hornaday says most cold-hardy bamboos are running bamboos…those fast-spreading types that gardeners either love or hate.
But the Fargesia bamboos are clumping, making them desirable for gardeners not interested in containing their bamboo patch.
Bamboo as an Agricultural Crop
Hornaday is hearing from a lot of people interested in farming bamboo commercially in North America. At the moment, he says, there’s a need for processing infrastructure. Farmers growing bamboo for commercial processing could also harvest shoots as a specialty food crop.
As a perennial crop that can grow on marginal land, it can be used to stabilize soil.
Grow and Cook Bamboo
Wendy Kiang-Spray on how to grow and cook bamboo.
Wendy Kiang-Spray’s children don’t recognize canned bamboo shoots. That says a lot about the difference between fresh bamboo and its canned cousin.
Kiang-Spray, author of The Chinese Kitchen Garden, grew up eating fresh bamboo, one of the many crops her father grows in his large garden.
She talks about growing, harvesting, and cooking bamboo.
Grow Bamboo
There are two groups of bamboo:
Running bamboos spread quickly by underground rhizomes.
Clumping bamboos grow in clumps.
Kiang-Spray points out that running bamboo might not be suited to small yards—at least not without measures to contain it. “It would be a big mistake in my suburban backyard; all my neighbours would hate me,” she says, as she talks about how quickly running bamboos can spread. A running bamboo spread to her yard from a neighbour’s yard over 100 feet away…not exactly a slow-growing plant.
To keep running bamboo in check she suggests:
Grow in containers
Plant on high berms (new shoots coming out the side will be easy to spot)
Instal a metal, plastic, or concrete barrier, buried to a depth of approximately 30 inches
Harvest Bamboo
Bamboo is harvested in the spring. Kiang-Spray says to use a knife — or to simply kick it over. “They should snap really easily,” she says, likening it to asparagus.
After harvest, cut shoots lengthwise and remove the edible “heart” by scooping it out with a thumb.
Fresh bamboo must be boiled prior to use to denature toxins. Boil uncovered for 30 minutes before use.
Urban Growers + Gardening Under Cover
Jamie Day Fleck talks about the urban growers she met while filming her documentary In My Backyard; and Niki Jabbour talks about garden covers and her book Growing Under Cover.
Today on the podcast we hear how one person’s journey into food gardening evolved into a documentary film — and then we find out how to use garden covers to take vegetable gardening to another level.
In My Backyard: A Documentary about Urban Growers
Torontonian Jamie Day Fleck converted her entire suburban backyard into a kitchen garden. That was the starting point of her documentary, In My Backyard, where she looks at ideas that urban growers have dreamed up in her hometown of Toronto.
Fleck talks about the urban growers she met while filming, how their gardens were different — and what they had in common. She also reflects on the future of urban growing.
Growing Under Cover with Niki Jabbour
We head to Halifax for food-garden inspiration from author, broadcaster, and vegetable gardening expert Niki Jabbour.
Jabbour talks about gardening in a polytunnel, reflects on her 2021 garden, and shares tips about how to use covers in the garden to grow more, protect crops from weather, and minimize pest problems.
Her newest book is called Growing Under Cover. It’s a must-have for serious vegetable gardeners.
Pawpaw in Ontario with Paul DeCampo
Paul DeCampo talks about growing pawpaw in Ontario.
Pawpaw. It’s a fruit that has a long history in Ontario.
Yet it’s not well-known, nor do most people realize it grows wild in some parts of the province.
Paul DeCampo, Toronto’s pawpaw ambassador, planted his first pawpaw trees in 1994. “Nobody I knew had ever heard of this fruit,” he says.
Working in the food industry, he has had the opportunity to share his pawpaw fruit with chefs. Describing how, years later chefs will still talk about a fruit he gave them, he says, “Even if you’re someone who spends all day tasting the most interesting things, these are particularly astounding.”
Why Grow Pawpaw?
Besides the fact that the fruit is almost never available for sale, DeCampo says a pawpaw tree is a good fit for the challenges of a city yard.
That’s because:
Pawpaw does not require full sun
Pawpaw grows well under black walnut trees (which give off a compound that is toxic to many other plants)
There are very few pests that affect pawpaw
DeCampo’s Pawpaw Tips
DeCampo suggests thinking of a forest-edge garden when planting pawpaw. For urban gardeners, the shade of the forest is replaced by the shade of buildings.
Other tips:
Get three plants (two genetically-distinct plants are needed to get fruit…but nothing is certain in gardening, so DeCampo says to play it safe, and get three)
Life is short, so buy as large a tree as you can find and enjoy the fruit sooner
Pawpaw Resources
Plants: Grimo Nut Nursery
Books:
The Pawpaw Grower’s Manual for Ontario, by Dan Bissonnette
The novel The Overstory, by Richard Powers. The pawpaw is described as, “A sheepdog of trees;” the fruit having flesh that tastes like butterscotch pudding.
Doug Oster uses Newspaper Boxes to Share Seeds
Doug Oster uses Newspaper Boxes to Share Seeds
Where have all the newspaper boxes gone?
If you’re in western Pennsylvania, don’t be surprised if you find a dark green newspaper box with a sign in the window that says “Doug’s Free Seed Shack.“
Pittsburgh garden expert Doug Oster, a newspaper industry veteran, is using old newspaper boxes to get seeds to as many people as possible. He wants more people to garden. And he wants vegetable seeds easily available in communities where access to fresh produce is limited.
Having seen pictures online of seed-library boxes, he thought about doing something similar in his hometown of Pittsburgh.
Oster, who jokes about not being handy, decided building boxes wasn’t his thing. Instead, he repurposed old newspaper boxes. All it took was spray paint and a trip to the print shop for signs.
After the first summer of the project, Oster says he’s pleased with the results. The seeds are getting into the community. He’s getting good feedback. And people are asking if they can share seeds in the boxes, which is exactly what he wants. He wants the seed shacks to be like a library, where people can take seeds—but can also return seeds if they wish.
Tips for a Seed-Sharing Initiative
Oster says he needs to fine-tune the seeds he’s sharing through the boxes. He started by sharing what he knows, and what he thought would be useful to new gardeners. For example, he thought perpetual spinach—which has a long planting window, is easy to grow, and has a mild taste—was a great choice. But there was little interest in the perpetual spinach seed. What that taught him is that people often want to grow foods they know and love.
Oster’s tips for seed-sharing projects include:
Find a go-to person in the community who can let you know when a box needs refilling and can give insights on how to make it successful
Put it somewhere with good access, and where people feel safe
Don’t be shy about asking for sponsors
A Windy Newfoundland Homestead with a Sustainable Focus
David Goodyear talks about his homestead at Flatrock, Newfoundland.
Old becomes new.
When David Goodyear began to think about food costs, sustainability, and how he and his family ate, he sat down with older relatives to hear how people used to eat. “Everybody ate root crops because they grew it themselves,” he was told.
Goodyear says there are many root crops that grow well in Newfoundland. It didn’t seem right when his grocery store had carrots from abroad. Nor did it didn’t seem sustainable.
Change in Diet Turns to Growing
Goodyear and his family started by changing their diet and eating more root crops. The food bill went down. They found more locally raised choices.
Then they decided to grow their own root crops.
Today they grow root crops, greens, tomatoes, strawberries…even figs. The next project? A food forest.
As Goodyear explains, his is a challenging climate. His town, Flatrock, is close to St. John’s, the third windiest city in the world. He has 110 frost-free days a year. “Winter starts in November; it doesn’t end till the end of May,” he says.
The focus on growing their own food led to an interest in storing the harvest. “If you’re going to grow a massive amount of root crops you need somewhere to put them,” says Goodyear as he talks about his root cellar.
Goodyear and his family switched up their diet; and have now switched up their life. Their homestead includes the gardens, a root cellar, a greenhouse, and a passive home.
How to Use Fig Leaves in the Kitchen
Chef David Salt talks about how to use fig leaves in the kitchen.
Coconut. Almond. Green fig.
These are some of the flavours people use to describe what they taste when Chef David Salt serves something flavoured with fig leaves.
Salt cooked with fig leaves in London, England, where he had a ready source of fig leaves in a nearby churchyard.
Upon relocating to Toronto, he didn’t know where to find them.
And that’s when host Steven Biggs received an enquiry that read:
“I am looking for fig leaves to make dishes with at my restaurant (fig leaf ice cream, jelly, savoury sauces, custards etc.) Is there any possibility of getting some from you, before they fall for the winter?”
Salt got some fig leaves, and invited Biggs to the restaurant to taste his fig-leaf ice cream, fig-leaf cheese—and a fig leaf grappa!
Cooking with Fig Leaves
Salt says that the most classic method of using fig leaves is in the same way as banana leaves — as a wrap. When used as a wrap, they protect the enclosed meat or fish, keeping it moist. They also impart a unique flavour.
The flavour is delicate. Salt finds it pairs well with light-flavoured meats or fish; and light-flavoured fruit such as strawberries and blueberries.
But he says to be creative: He’s paired fig leaves with hot chocolate, a strong taste, and found worked well.
His favourite dish made using fig leaves is ice cream.
For people using fig leaves for the first time, he explains that heat can help to bring out the flavour—but to avoid boiling, which results in a stewed-vegetable flavour. When time permits, a cold infusion is best.
Drifter’s Solace
Salt is gearing up to create fig-leaf flavoured foods this fall at his brand new chef’s-table style restaurant in Toronto. It’s called Drifter’s Solace.
Toronto has lots of big restaurants. Drifters Solace is at the opposite end of the spectrum: It’s small and personal, for groups of 6-8 people.
How to Forage for Mushrooms without Dying
Frank Hyman talks about how to forage for mushrooms.
Mushroom identification can be daunting for beginners, with Latin names and spore prints used to differentiate hard-to-identify mushrooms.
In his new book, How to Forage for Mushrooms without Dying: An Absolute Beginners Guide to Identifying 29 Wild Edible Mushrooms, Frank Hyman focuses on edible mushrooms that are easy to identify.
Easy-to-Identify Edible Mushrooms
Hyman suggests starting with easy-to-identify mushrooms when learning to forage — mushrooms that can easily be distinguished from non-edible ones.
Here are some of the mushrooms that he talks about in this episode:
Chicken of the Woods. “It will look like a pizza sticking our of a tree.”
Morel. Easy to distinguish from the non-edible false morel because the entire interior is hollow when sliced in half from top to bottom (the false morel has chambers within it.)
Black Trumpet (a.k.a. Horn of Plenty). These mushrooms, which look like little bugles, are hollow tubes. Pick it up and look through it length-wise, as if it were a telescope.
Giant Puffball. Slice in half to see that the interior is solid white. “If it’s white like a piece of tofu, you’re good to go,” says Hyman. If you see the outline of a mushroom within, or if it’s not white — don’t eat it.
More than Dinner
Hyman points out that along with the culinary uses of foraged mushrooms, there’s another reason people might consider foraging: It’s a fun outdoor activity; it’s time outdoors, in nature.
Backyard Chickens
Hyman is also the author of the book Hentopia: Create a Hassle-Free Habitat for Happy Chickens; 21 Innovative Projects.
Here is a video in which he talks about backyard chickens.
Are You Frightened of Landrace Gardening?
Joseph Lofthouse talks about landrace gardening and promiscuous tomatoes.
Joseph Lofthouse had hundreds of jars of seed around his house when he began market gardening.
He saved seeds from each variety…a time-consuming task.
Today he has far fewer jars of seed. Today he practices landrace gardening.
Lofthouse no longer focuses on keeping pure varieties, but instead uses genetically diverse lots of seed.
His is the author of the book, Landrace Gardening: Food Security through Biodiversity and Promiscuous Pollination.
What is Landrace Gardening
Landrace gardening is not new. It’s a traditional method of growing using locally adapted, genetically variable seeds. The genetic variability makes it more likely that some plants will perform well even if there are adverse conditions.
“What I’m doing was standard practice through all of human history up until about 60 years ago, until people started farming with machines instead of human effort,” explains Lofthouse.
How to Start Landrace Gardening
Not having pure varieties feels strange to some gardeners. But Lofthouse points out that uniformity isn’t important in small-scale operations or home gardens.
Here are his tips for gardeners who want to try landrace gardening:
Grow and save seeds of a favourite variety
Then grow another variety of the same crop with desirable traits next to it
Aim for 2 - 5 varieties of the same crop from which to start your landrace
Lofthouse notes that there are some crops for which he avoids certain mixes. For example, he does not mix his popcorn with his sweetcorn; or his hot peppers with his sweet peppers.
Helping Other People Eat through Gardening
Julie Brunson didn’t garden as a child, but began to garden and grow food as an adult. When her husband was in a dark place and found solace in their garden, the garden not only fed them, it helped him to heal.
That was the start of a journey into teaching kids about regenerative gardening, and also using the garden as a way to touch on a host of other topics including social justice, mental health, and nutrition.
Container Gardening with Hot Peppers - REWIND
Claus Nader from East York Chile Peppers on growing hot peppers in containers.
Hot Peppers
What is the ideal plant for a small yard?
The ideal plant for someone wanting something ornamental – yet edible too?
And, just to complicate things, it has to be good for a garden where there are lots of squirrels.
Claus Nader found that hot peppers were that ideal plant.
Nader was gardening in a small yard that was frequented by marauding squirrels. While the squirrels sampled many of the things he grew, they didn’t eat his hot peppers.
So Nader made hot peppers the focus of his garden, growing them in pots on his balcony, deck, and dotted around his small yard.
Along with a passion for growing peppers in containers, Nader is also interested in unusual varieties and culinary uses and traditions. (His “Tummy Torch” sauce is magic on a piece of barbecued chicken.)
