To know how much to fertilize you will need a soil test. In general 10-10-10 is adequate for most vegetable gardens. There are directions on the label about how much and when to apply it. There are also fertilizers labeled for flowering. If you are on the Anoka sand plain your garden might benefit from an extra boost or benefit from adhering to the fertilization schedule on the package. Most gardens do well without added fertilizer. Most vegetables grow well if the pH is between 6.0-7.8.
