What this book teaches
The arithmetic a garden actually asks of you, in the order a season asks it: how big the beds really are, including the awkward L-shaped and circular ones; how much soil or mulch that means, in bags and in cubic yards, and which of the two is genuinely cheaper; how many plants a bed holds at the spacing on the seed packet, and how many seeds to buy for it; how to plan backwards from the jars you want in the pantry to the plants that fill them, losses included; how to turn two frost dates into a seed-starting calendar and a last-sensible-planting deadline; how to size a pot in gallons and check what it weighs on a balcony; and the estimates that get you through the garden centre without a calculator. Series brand: Math Didn't Have To Be This Hard.
