My fiancee and I just bought our first home and I'd like to start my journey of vegetable gardening. The previous homeowners have 3 raised beds on the South side of the house. We haven't moved in yet so I'm not able to verify the amount of sunlight they get, but I'm going to assume (for now) that it's in an adequate spot.
How should I take over their raised beds? I have no idea how good of condition their soil is in (i.e. maybe they haven't touched the garden in years or perhaps they take great care of it).
Should I do a soil test when we move in? Or should I assume the soil is lackluster and instead put in a mixture of compost and topsoil? Or should I do something entirely different?
