  • I find most of podcasts done on Thech on demand are very useful. The tissue culture episodes were very informative as well as the episodes about water and VPD.

    You have a fan indeed here.

4 Questions for Leslie, a Green Industry Consultant, Author, Educator (and more …)
Q: What advice would you give to a young person considering horticulture?
She urges thorough industry discovery, understanding the full range of potential jobs, pursuing appropriate credentials, and choosing paths based on personal aptitudes and people you want to work with, not just love of plants.
4 Questions for Leslie, a Green Industry Consultant, Author, Educator (and more …)
Q: What three tools could you not live without?
Her essentials include a coffee fuel, a camera (or smartphone), and powerful technology like an iPad and laptop, plus the need to document work through photography and have reliable access to software suites for business and creative work.
4 Questions for Leslie, a Green Industry Consultant, Author, Educator (and more …)
Q: What is something about professional horticulture that annoys you, and how would you change it?
Her frustration centers on the industry's resistance to change and its reactive nature; she argues for proactive, data-driven decision making, better forecasting, and people embracing new business models to improve profitability and resilience.
4 Questions for Leslie, a Green Industry Consultant, Author, Educator (and more …)
Q: Do you have a morning or evening routine you'd like to share with the listeners? And why do you do this?
Leslie explains she's a morning person who used to start with analytical work, but after a sabbatical she shifted to a slower morning with more creative writing, reserving heavy tasks for later; this evolution is about listening to her brain's flow and adapting to new circumstances, including moving to Oregon and changing life rhythms.
4 Questions for Kelly, a North American Head of Technical Services
Q: What advice would you give to an industry veteran currently dealing with burnout?
Talk to a trusted colleague, take a true break away from emails and devices, and create a pro/con list to re-evaluate purpose and potential changes within the company.
