Talking Points

Recent interactions between the hosts and their guests.

Ep.83 - Allan Armitage and Marisa Reyes Dish on Their Favorites From the 2026 California Spring Trials
Q: So to start us off, what was your biggest takeaway from CAST?
Allan notes that CAST showcased a mix of breeders' best efforts with a trend toward smaller, retail-friendly introductions that address production challenges, while Marisa emphasizes the intersection of retail trends and grower practicality, with compact plants and multi-use concepts as key takeaways.
Ep.82 - Perspectives on Becoming a New Green Industry Business Owner, Featuring Amy Ryan
Q: How did the ownership transition get communicated to the team and what was the process like?
The team was informed with a lunchtime meeting in mid-December after careful planning and multiple considerations, and mentors from the former ownership remained available to support the transition.
Ep.82 - Perspectives on Becoming a New Green Industry Business Owner, Featuring Amy Ryan
Q: Let's start with your background and how your past experiences prepared you for this new role.
Amy shares a long trajectory from working on the potting line as a teen, returning to horticulture in college, stints in culinary arts, then moving into nursery roles that built both technical and people skills, ultimately leading to ownership of Stonehouse Nursery.
Ep.81 - Innovations in Plant Pathogen Testing, Featuring Lizzy Blossom and Ceragen
Q: Can you share a case study where testing changed the course of treatment for a grower?
A case where sequencing showed phytophthora rather than a presumed pythium issue, guiding the grower to adjust the treatment strategy to address the true pathogen and avoid ineffective solutions, illustrating the value of a full-screen microbiome approach.
Ep.81 - Innovations in Plant Pathogen Testing, Featuring Lizzy Blossom and Ceragen
Q: What are the future innovations Ceragen and Lizzy Blossom are exploring?
Both are pursuing improvements in sequencing-based testing, finer understanding of pathogen thresholds, and broader crop coverage; there is also interest in applying CRISPR-related approaches for diagnostics and trait development, along with continuous monitoring to optimize fungicide use.
