  • Podcast #9: Telsing Andrews of Aster Lane Edibles

    In this episode of the Cultivariable podcast, I talk with Telsing Andrews, a nursery owner and plant breeder based in Ontario, Canada.  We talk about the struggles of running a small nursery, sweet potato breeding, chufa, cabbage, chickpeas, sea kale, carrots, multiplier onions, and many of her other favorite plants.

    You can contact Telsing and buy seeds at Aster Lane Edibles.  If you want to buy seeds, don’t delay, because she is closing down the business in March!

  • Podcast #8: Chris Homanics

    In this episode of the Cultivariable podcast, I talk with Chris Homanics, a plant preservationist, breeder, and farmer in the Willamette Valley. Chris is well known for his work with perennial kales and chestnut preservation and breeding.  He also does a lot of work with fruit trees, particularly apples, pears, and persimmons, and is very active in regional efforts to preserve and expand agricultural biodiversity.

    As is often the case, this interview was done over cell phone and outdoors, so the noise gets a bit thick in places.

    You can find Chris on Facebook and you can also donate to help with his preservation work.

  • Podcast #7: Doug Strong of Windmill Hill Farm

    In this episode of the Cultivariable podcast, I talk with potato breeder Doug Strong.  Doug specializes in breeding diploid potatoes and has produced a bunch of really interesting varieties that are well known by Andean potato enthusiasts, such as Big Dog, Black Hornet, Yellow Dog, and Strawberry Timepiece.

    Due to background noise, I had to chop this recording up a little more than usual and some cuts forced me to rearrange sections so that they would make more sense.  In a few places, this leads to weird transitions like asking questions that have just been answered.  I did my best to keep as much as possible.

    You can follow Doug’s work at the Kenosha Potato Project on Facebook:

  • Podcast #6: Joseph Lofthouse

    In this episode of the Cultivariable podcast, I talk with farmer and freelance plant breeder Joseph Lofthouse.  Joseph is well known for his landrace plant breeding, a method that he has popularized and applies to an astounding 100 species of food plants.  We talk about his breeding philosophy and how he has used it to improve crops such as squash, cantaloupe, potatoes, and tomatoes for his short season climate.  Joseph collaborates widely on his projects and also sells seed.

      • Podcast #3: Tom Wagner of Tater Mater Seeds

        In this episode of the Cultivariable podcast, I talk with Tom Wagner of Tater Mater Seeds.  Tom is a well known public domain breeder, based in Everett, WA, who has worked with tomatoes, potatoes, and corn for more than sixty years.   We discuss potato and tomato breeding, the history of some of his varieties like the Green Zebra tomato and the Skagit Valley Gold potato, and about the future direction of his work.

        Many of the links that I am listing are not very active, but Tom is planning to do more online, including starting his own podcast, so bookmark these links and stay tuned.  Tater Mater Seeds is not currently open for sales.  Tom’s forum is open and he is hoping for more people to post there.  There is a huge wealth of information there, so it is well worth signing up.

      • Podcast #2: Curzio Caravati and the Kenosha Potato Project

        In this episode of the Cultivariable podcast, I talk with Curzio Caravati of the Kenosha Potato Project and Kenosha Urban Farm Institute about collecting potatoes, growing potatoes in an urban farm environment, and growing potatoes from true potato seeds (TPS).  Along the way, we discuss farmers markets, how potatoes can be classified by their agronomic and edible characteristics, working with the USDA Potato Introduction Station at Sturgeon Bay, how basketball hoops are like growing bags, the similarities between plant breeding and honeybee breeding, and why you should eat more dirt.  Some of the potato varieties that are mentioned include White Peachblow, Raudar Islenskar, Bintje, and Blue Victor.

        Unfortunately, this episode was a particular challenge to edit.  We had some audio quality problems with the recording and there were parts that I just couldn’t salvage, creating some odd jumps.  Hopefully, I will get better at this as I gain more experience.

      • Podcast #1: Nathan Kleinman and the Experimental Farm Network

        In this first episode of the Cultivariable podcast, I talk with Nathan Kleinman of the Experimental Farm Network about participatory plant breeding, sustainable agriculture, and some favorite plants like sorghum, chinquapin chestnuts, and perennial kales.  The Experimental Farm Network connects breeders with trial growers all over the country, making it possible to speed up variety development.
