In the raised bed garden that's the 'main vegetable garden,' I try to practice intensive raised-bed gardening, loosely based on the square-foot method. I'm afraid I'm not methodical enough to be precise about planting -- frankly, I like to play with my garden, but I do try to rotate vegetables as I can.
We eat as much as we can from the garden, but having it look nice is important, too. The garden is right out the kitchen door, so I think about it as a perennial vegetable/flower bed, even if it's made up of annuals. I want it to be pleasing throughout the year. Rotating out plants, reseeding, and routinely adding more compost and amendments; all of these things are part of my gardening year.
