Life-long vegetable grower and cucumber connoisseur Sue Stickland shares her secrets of success for growing cucumbers outdoors. Garden designer Paul Spracklin encourages us to brave the prickly pleasures of outdoor cacti. His Essex garden (in the driest part of the country) contains dozens of species normally seen only under glass. Plus RHS Entomologist Andy Salisbury encourages us to take a closer look at some of summer's finest songsters; crickets and grasshoppers.
