Introduction

Polytunnels are a game-changer for gardeners, offering the ability to extend growing seasons, protect crops, and maximize yield. Whether you’re a seasoned allotment keeper or a beginner gardener, investing in a polytunnel can transform the way you grow plants. This article dives into everything you need to know about polytunnels—from choosing the right one to maintenance tips—so you can make the most of your gardening experience.
