Thanks for the question. Congratulations on your new house and dudes for wanting to start a vegetable garden.
We always recommend a soil test for your lawn and garden every 3 years or so. The general test will tell you the composition of your soil and the nutrients in it currently and will give you a recommendation for fertilizer, if needed. You can also test for lead if you have concerns or other micronutrients.
Testing for PFA’s is general for water. I see that you live in Hennepin County. IF you have city drinking water you should be able to find analysis on their website. IF you have a private well, information from the MN Department of Health is below.
Also, if you are starting a vegetable garden we have a Vegetable Growing Basics class starting March 7th if you are interested: These classes are offered every year.
