The Good Growing Guide is a series of quick-reference, downloadable postcards with all the information you need when you’re in the thick of gardening. We all need fat gardening books to teach us about the best techniques and the most reliable, tasty cultivars. But we can’t lug them to the allotment, and if we did, they’d get awfully muddy. So these cards tell you everything you need – planting depth, when to sow and feed, and when to harvest. That’s all.
