Why Spraying Won’t Stop These Weeds
In this clip from the EcoFarm Aotearoa Podcast, Ewan breaks down why weeds like barley grass, docks, mallow, and even cape daisies appear and why spraying or aerating with a tractor rarely solves the real problem. These plants aren’t “mistakes”; they’re responding to compacted, anaerobic, or mineral-imbalanced soils, often where calcium is present but unavailable due to missing trace elements.
Ewan explains how bringing oxygen back into the soil through biology, especially cyanobacteria, is the key to shifting weed pressure naturally. Instead of fighting weeds with chemicals, he shows how fixing limiting factors, improving soil structure, and restoring fertility causes problem weeds to disappear on their own.
