The resurgence in home food production has generated a dramatic increase in interest about growing under cover. The season is far longer (year-round for salads and some vegetables) and you can grow exciting fruit and vegetables that aren't viable outdoors. Thanks to the polytunnel, covered growing is now available to all. And sales of polytunnels are burgeoning, as gardeners and allotment-holders realize that they could be growing more food (and more exotic food) on a smaller plot, whatever the weather outside is doing. The Polytunnel Book is the first comprehensive, practical illustrated guide to polytunnel gardening, for both beginners and experienced gardeners.
