A patch of struggling soil on a Taranaki lifestyle block sparked a line of questioning that wouldn’t let Michelle and Frank Lachmann go. What began as hands-on experimentation soon turned into years of trial and error, obsessive research, and a deep fascination with the invisible world beneath our feet. That curiosity became Herbi.nz, a next-generation soil and plant food now trusted by home gardeners, market growers, and international partners alike.

In this episode of the PowerUp Podcast, Michelle and Frank share the real story behind Herbi.nz’s evolution. From the failed hemp crop that sparked it all, to the decisions, values, and practical lessons that transformed a side project into a fast-growing business. They speak openly about parenting while building a company, navigating uncertainty, and staying true to their beliefs about health, nature, and simplicity.

They also reflect on the role Taranaki played in their journey, offering space to experiment, strong community support, and a grounding connection to the land.

Herbi.nz began with a problem and that’s often where the best ideas grow.
