  • 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.

The Summer of Soiree Kawaii ft. Suntory’s Lorentina Fielding
Q: What support is there for growers in terms of production and supply?
We have URCs and liners available, with Costa Rica-based NovaPlan as a key supplier, and a focus on maintaining steady supply while navigating regulatory constraints; the guidance covers sizing (72-105 cells) and propagation timelines.
The Summer of Soiree Kawaii ft. Suntory’s Lorentina Fielding
Q: How do you position Soiree Kawaii in the market after 10 years?
We position it as a versatile, border-friendly, color-rich filler that can pair with other tropicals in combos, and we emphasize its compact, mushroom-like growth habit that suits both containers and landscapes.
4 Questions for Jose, a Sales & Business Manager
Q: What advice would you give to a young person considering pursuing a career in horticulture?
He encourages embracing hands-on work, staying curious, and recognizing that there are many paths in the industry—from production and scheduling to marketing and science—and that the field offers meaningful work for those who are passionate about plants and community impact.
4 Questions for Jose, a Sales & Business Manager
Q: Question one, what was your first exposure to horticulture? And how did you feel, react, or respond?
Jose describes being exposed to the landscape industry at age eight with his dad, doing gardening tasks, and realizing early on the value of hard work, responsibility, and hands-on involvement; he emphasizes that working with his hands is a legitimate, fulfilling career path and that there are many avenues within horticulture beyond traditional nursery roles.
Rotating from Resistance to Results ft. Envu’s Dr. Janna Beckerman
Q: Can you explain what mode of action is?
Mode of action describes how a product targets a pest at the cellular level, with different products affecting different receptors or biochemical pathways; understanding this helps in designing rotations that avoid cross-resistance.
