If you have no earthworms it will take a couple years of wacking the compost and sheep shit or some other animal poo to your earth before your soil really yields good veggies. Plant every year anyways. You will always get something, but after a couple years of making your soil rich things will really start to take off. Raised beds for each individual vegetable is the best way to go. Then you can get as anal as adjusting the ph of each bed depending on what you want to grow there. I find that planting alfalfa, rye, clover or something of that nature as a cover crop in between rows also adds a lot of nitrogen to your soil at the end of every season when you till it under. the fall is also the best time to plant your garlic for the following spring.
been behind this summer though
