““After many experiments, I found that three of my favorite ingredients made the perfect mix when combined in equal portions: 1/3 Peat Moss—Available at any garden center or supermarket. 1/3 Vermiculite—Buy the coarse grade in large 4-cubic-foot bags at any garden center or home improvement store. Phone ahead to be sure it’s available in that size. 1/3 Blended Compost—If you don’t have your own compost operation, then buy bags of compost at the garden center to get started. Then, start your own compost pile as soon as possible. I’ll explain some simple steps for foolproof composting later in the book. However, one word of caution here: You must have a blended compost, so don’t buy all the same kind. Pick out one bag of this and one bag of that. But, more about that in Chapter 5.””
