One thing that always bothered me about the Little House books was how a garden of less than an acre could supply all the vegetables for a family of five. I'm starting to understand how much output you actually get from the plants when you're a halfway successful gardener.
Artie and Kale each have their own areas, with about ten square feet total. Kale has two servings of leaves ready about once a week. I had to harvest Artie's second round of buds before they opened, and each of the three was a serving. There is a set of grandbabies, Heidi, and a few great-grandbaby buds that will be ready for picking before I go on vacation next week. They will be too small for full servings, but big enough to marinate or freeze for later.
