Summary

In the 4th podcast of our Foundations Series, we revisit a masterclass in applied horticulture with Don Marshall. With over 40 years of teaching experience, Don explains why a "green thumb" isn't magic—it’s the result of understanding botanical science. We move beyond garden hacks to identify the limiting factors that prevent plants from reaching their full potential.

Welcome back to the show. You're listening to the fourth podcast in our foundation series,

plant science and cultivation. Today we are revisiting a masterclass with Don Marshall.

Don has spent over 40 years teaching students that a green thumb isn't a gift. It's the result

restraints in everyday life. I'm hoping this course will allow growers to better understand the core concepts of botany
