Allotment Watering During Hosepipe Ban: The £4 Olla Hack That Beats Evaporation

With southern England under an active hosepipe ban and a second heatwave of 2026 pushing soil temperatures past the point where surface watering stops working, this video covers the single most cost-effective solution I've found: olla subsurface irrigation using repurposed terracotta vessels from your local garden centre or charity shop. I explain why your allotment soil becomes hydrophobic above 28°C, how up to 70% of can-watered water is lost to evaporation before reaching roots, and how a £2–5 unglazed terracotta pot buried at the correct depth can bypass all of that — delivering stored rainwater directly to the root zone using capillary action, fully legal under every Temporary Use Ban currently in effect in the UK. You'll find a full setup checklist, depth and spacing guide, and water butt compatibility notes in the pinned comment below.
