Hi: I have been gardening for 40 yrs and my advice to you is to take about 1/2 cup of soil from several spots in the area you want to plant and put each into its own zip lock sandwich bag and take or mail them to your local university extension center mine in MI does it for free. They will test your soil and let you know what you need to add to bring it up to planting condition. Its usually pretty easy. From there just mix in what is needed and you are good to go. You can also buy a testing kit at your local garden supply center and do it yourself, but I prefer the extension center. I'm sure if you search this site you will find an article on soil condition.
