Mechanizing Agroforestry — with Bob Walker

Plant The Trees ·

2026/04/09

How do you further mechanize tree planting? Where are the leverage points? How do you get the trees on a perfect grid or a Keyline grid, at inch-accurate, GPS-guided intervals? Can you mow, subsoil, rototill, seed, and mark all in the same tractor pass? Bob Walker is a core member of the Propagate Team. He has decades of experience farming, and I’m really thrilled to finally get him on the podcast, because he’s the guy that makes all of our work truly efficient and effective. Here we’ll dive ...

2026/03/24

Before you plant apples, blueberries, and black walnut, try these 5 species instead. I started out 15 years ago planting black walnut and apples, because apples are the go-to fruit and black walnut veneer logs can pay off a mortgage. But what other species can feed us, create economic value, and provide ecosystem benefit with a more gradual learning curve?

Plant The Trees ·

2026/02/11

How are we paying for trees? How are you paying for trees? At the end of the day, there is no free lunch. We’re either paying with our time, or paying with our wallet. We’re going to explore both sides of that coin, and hopefully leave you with a better understanding of funding agroforestry in the United States. If you’re not in the US, you’ll still get a lot out of this episode. Link for how to work with us: https://www.propagateag.com/technical-assistance

Hickory Oil and Damp Soil — with Jesse Marksohn of...

Plant The Trees ·

2026/02/05

Farmland is often considered marginal because it’s rocky, steep, or because the soils are too shallow. But in much of the northeast and midwest, farmland is “sub prime” or less productive because it’s wet or poorly drained. Not wetland, but damp farmland that’s harder to access until it’s dry in mid summer. The question here is: what tree crops work for this soil? Chestnuts don’t like clay, or wet feet. But yellowbud or bitternut hickory is a great fit, and this tree produces high quality cul...

Global perspectives on forest-driven economies. It’s easy to confine ourselves and our thinking to our own countries, states, and bioregions. But we all live on one planet, and the integrity of our rural economies and our ecosystems reaches beyond the borders of our nation states. Today we’re joined by İsmail Belen and Marton Németh. İsmail is from the country of Türkiye (Turkey), and he is the Chair of the United Nations Forum on Forests and the Inspector General of The Turkish Forest Servic...

Byron and I first encountered syntropic agroforestry in the same way. There was a stunning documentary released in 2014 called Life in Syntropy. It profiled farms in Brazil utilizing planned ecological succession to grow food and restore the vibrant, verdant Atlantic Rainforest. Now we both incorporate the processes and practices of syntropy into our work, Byron to a much greater extent than I do. We always look to adapt the principles to different people and landscapes around the world. We a...

2025/12/03

Julie Richards stewards the operations of Ohio Chestnuts and Wintergreen Tree Farm. 200+ acres of chestnuts produce great food for real people, while improving water quality in the streams and creeks that flow into Lake Erie. Julie grew up with chestnuts, and came back to the family farm not just because chestnuts are really satisfying crop to work with, and not just because she had the opportunity, but because it was a really good financial and logistical decision for her and her family.

2025/11/26

It’s 1972. Led Zeppelin IV just hit the airwaves, and Greg Miller is planting chestnut trees as a junior in high school. With time on his side, he goes on to get a PhD in plant breeding, and vastly improves chestnut yields, nut quality, and disease resistance. 50 years later, the trees are still bearing huge crops. Greg has planted tens of thousands more trees, having refined the genetics over multiple generations of Chinese Chestnut and Chinese-American hybrids. Widely regarded as the pionee...

2025/11/19

What do agroforestry-interested land managers have in common? And how do they differ? Are they open minded and risk averse? Are they extroverted and orderly? Our hypotheses, based on working in this space for 10 years, may surprise you. It’s well established that we have to fit the tree species to the soil type. Listen on if you’re curious about aligning the tree species with the people that are managing the land.

Russell Wallack, founder of Breadtree, joins us to talk chestnuts and perennial pantry stables. Breadtree farms on 800 acres in the Upper Hudson Valley (NY) and Southwest Vermont, where they steward 20,000+ food-producing trees and shrubs — including chestnut, hickory, oak, seaberry, apple, pear, mulberry, and persimmon — in orchards grazed by sheep and cattle. The practice of raising food crops, trees, and animals together has a long history in many cultures, and (today) is often called agro...

Take a listen to this phenomenal interview with Dana Shapiro, CEO of the Hawai‘i Ulu Cooperative. Ulu is the Hawaiian word for Breadfruit, which is a tree crop starch that traveled across the Pacific Ocean in canoes, and can still grow straight out of lava rock. And the conversation got. good. and I think we did a solid job of profiling this case study in rebuilding a food system with agroforestry. Hawai‘i imports 90% of its food, while half its farmland is fallow. Meanwhile, Dana and her tea...

Silvopasture in Argentina

Plant The Trees ·

2025/10/15

Silvopasture is the intentional integration of trees, forage, and livestock, and Northern Argentina boasts over 200,000 acres of plantation silvopasture. If we’re going to make more silvopasture happen in the United States, it’s good to learn from similar climates, even if they’re in the Southern Hemisphere. In this episode, we talk to Luis Colcombet, who is a silvopasture veteran, and an agroforestry agronomist and scientist with INTA in Argentina. He’s been working in silvopasture for decad...

The Climates and Agroforestry of Argentina

2025/10/08

Argentina is full of agroforestry. From 200,000 acres of silvopasture across the northeast, to thousands of miles of windbreaks in Patagonia, to shade-grown yerba mate, trees on farms just make sense. It's incredibly helpful to compare agroforestry systems across different climates and different economies, and we can learn a great deal about our own climate and agroforestry through the lens and the experience of another unique but similar region.

2025/10/01

Here we have our first Australian on the Plant The Trees Podcast. I first met Darren Doherty at a Keyline agroforestry course in Iowa City in 2014. Back then we sometimes called it permaculture, but you could say that sphere was starving for pragmatism. How could we add financial realism to a socially-inclined ecological agriculture? There are so many things we can do on a landscape, but where do we start? And what goals and ends do we have? The Regrarians platform gives extremely thoro...

2025/09/24

When we try to transform the world’s distressed or abandoned farmland, we'll come across a massive leverage point. That can be a new technology. Or it can be a tree species. Today we’re going to the country of Hungary to focus on a very unique tree. It grows fast, fixes nitrogen, and produces timber that rivals tropical hardwoods in strength and durability. In Hungary, it’s a species that’s woven into songs, poetry, and everyday life — but in parts of Europe and even its native landscape, it’...
