A polytunnel can be used as an affordable, low-carbon aid to growing your own food all year round, from crispy salads and fresh vegetables in the dead of winter to juicy melons and mouth-watering grapes in high summer. But once you've decided to invest in a polytunnel, there are many questions to be answered, including: * Do you need planning permission? * What are the different sizes and types you can buy? * Where should you put it, and how do you put it up? * What can you use it for, how do you look after it, and what are the likely problems? The Polytunnel Handbook looks at all aspects of using a polytunnel, from planning your purchase to harvesting the rewards, and includes a step-by-step guide detailing how polytunnels are put up and maintained. There are chapters on developing healthy soil and preventing pests, and a jargon-free guide to the range of often mystifying accessories that many tunnel retailers offer.
