Not Enough Sun: The Shade Gardener’s Guide to Growing Food — Reading Your Light, Picking Crops That Deliver, and Skipping the Ones That Won’t (Grow Food Anywhere)

You counted the hours. You got three. Every vegetable gardening book opens with the same sentence: choose a site that receives at least six to eight hours of direct sunlight per day. You read it, looked at your yard — the neighbor’s maple, the north wall, the six-foot fence — and concluded the book was not written for you.

That sentence is not a rule. It is defensive writing, calibrated so the author never receives a complaint. It counts hours, which are a poor measure of light, and it ignores the diffuse light from open sky that a shaded bed actually lives on.

Not Enough Sun replaces it with numbers.

What this book gives you Three ways to measure the light you actually have, using a notebook and the phone in your pocket Daily light integral — the unit commercial greenhouse growers run on — explained plainly, with a method for estimating yours without buying equipment A crop list sorted into three tiers by what each plant genuinely requires, with named varieties, spacing, and realistic days to maturity A planting calendar anchored to your own leaf-out date and your own ten-hour date, not to a frost date that was never the binding constraint A diagnostic routine that settles most failures in one afternoon with a spade and a soil thermometer Honest yield figures, with the shade discount already applied What it does not do It does not promise you tomatoes. One chapter is a detailed and unsentimental account of exactly why fruiting crops fail below a certain light level, and what to grow instead. The most expensive thing about gardening in shade is the season you spend finding out.

Also covered Cold, wet soil, and the mulch timing that quietly makes it worse. Slugs and mildew, and why diatomaceous earth is useless in the exact conditions where slugs live. Tree roots taking your water and nitrogen — the most under-diagnosed problem in a shaded yard, with a ten-minute test that settles it. What crown thinning actually gains you, and why topping a tree makes shade worse within three years. Reflectors: what works and what is folklore. Grow lights, with the arithmetic done in front of you.

Three appendices: a crop light requirement table, a light survey worksheet, and a troubleshooting quick reference.

Written for any temperate climate. No regional planting calendars and no zone maps — the physics and the plant behavior, which travel everywhere, plus explicit instructions for translating both to your own frost dates and your own summer.

Your yard is not disqualified. It is only unmeasured.
