Episode Title: Ecological Weed Management
Host: Edgars Greste
Guest: 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 your enemy — they’re nature’s message.” When you begin to listen, to interpret what those weeds are telling you about your soil, pasture and farm system, you shift from reacting to guiding your system. This isn’t about perfection — it’s about progress, one paddock and one season at a time.
