Ecological Weed Management - Regenerative practices
Episode Title: Ecological Weed Management
Host: Edgars GresteGuest: Kim Deans, Agro-ecologist (with special contributions from Alexia Martinez & Kym Green)In this episode of The Big Shift for Small Farms, Edgars Greste takes a deep dive into the often-overlooked subject of weeds — and how thinking differently about them can transform your small farm. Joining him is agro-ecologist Kim Deans, who challenges traditional chemical-based weed control, and instead advocates for a holistic weed-management strategy grounded in soil health, biodiversity and sustainable farm practices.
You’ll also hear from farmers Alexia Martinez and Kym Green as they share firsthand experiences of integrating compost, cover-crops and natural remedies into their weed-control practices — showing how a small-farm operator can manage weeds and build a healthier ecosystem at the same time.
Why weeds aren’t just pests — they are indicators of underlying soil, pasture or ecosystem health issues.
How to shift from a reactive “spray-and-pray” mindset to a proactive system-based approach focusing on soil biology, cover crops, grazing and pasture competition.
Practical strategies for small farms in Australia: implementing cover crops, compost, rotational grazing and non-chemical weed suppression methods.
Real-world farm stories: how Alexia Martinez and Kym Green are balancing weed control with regenerative practices on their properties.

Where to from here?
Walk a paddock, and document which weeds are present, how dense they are — and ask: What might they be signalling about soil health or pasture competition?
Choose a paddock to trial a cover-crop (or increased ground cover) this season. Compare weed pressure at the end of the season with a part of the paddock left under current management.
Talk to a neighbour/mentor/agribusiness about integrating grazing or compost strategies to suppress a particular persistent weed species you face.
Then, set a reminder: revisit the same paddock in 3 months, note changes and score weed pressure on a scale of 1-10. Reflect: What changed? What still needs adjusting?
On smaller farms, conventional large-scale weed-control methods (heavy chemical sprays, large machinery) may be less economical or sustainable. By adopting an ecological approach, you gain:
Improved soil health that supports your desired plants & crops, not just suppression of weeds.
Reduced reliance on chemical inputs and lowered costs — especially relevant in tight-margin scenarios.
More resilient systems: healthier soils and beneficial plant cover help your farm bounce back from droughts, floods or other extreme conditions.
As Kim Deans reminds us: “Weeds are not just
