Episode 165: Frost Protection Basics

Frost season is here — and if you’re in a cold pocket like the Southern Tablelands, you already know it can wipe out a garden overnight. In Episode 165 of Ditch The Store, I’m walking you through frost protection basics: what frost actually is, how to judge your risk, the cheap methods that work, and the common mistakes that make things worse. Quick personal note first: Tuesday was my “D‑Day” — I’m saw the surgeon to check the X‑ray and find out whether the bone graft in my leg has taken. If you’ve got a spare good thought, send it my way. In this episode What frost is (ice crystals forming on plant surfaces below 0°C) Why clear, still nights are the biggest frost risk (clouds = a blanket) Frost pockets and why cold air behaves like water (it sinks and pools) How to judge your frost risk: light frost vs hard frost Knowing your first/last frost dates (and why late surprise frosts happen) What gets smashed first (the drama queens) vs what can cope Microclimates you can use to “cheat”: Brick walls + under eaves Evergreen shelter (with the trade-off of shade) Near water (more stable temps) 5 frost protection methods: Cover plants (frost cloth, sheets, cloches, plastic with a frame) Mulch (stabilises soil temps + suppresses weeds) Watering (moist soil holds heat — but water early, not at night) Move pots (verandah, greenhouse, shed/garage overnight) Windbreaks + airflow management (wind strips warmth and dries plants) What NOT to do: Plastic/fabric sitting directly on leaves Leaving covers on for days without airflow/light Pushing nitrogen fertiliser in winter (soft growth = frost damage) Ignoring weeds (they don’t take winter off) Protecting specific plants: seedlings vs established plants, herbs, leafy greens, root veg Winter infrastructure checks: hoses, taps, irrigation lines, frozen pipes A simple frost-night checklist (forecast → cover → mulch → move pots → uncover) Australian cold zone map (https://canva.link/wthzfa19m20cmbi) Mentioned Next week What you can still grow in winter — including ideas for different zones (not just mine).
