Matt/Indy –
Most plants thrive in well-drained, slightly acidic, soils that are rich in organic matter. The challenge, however, is that most of the world’s soils do not exist this way and they must be balanced, or amended, to provide the conditions necessary for robust plant growth.
Always start with a soil test, amend accordingly and add plenty of organic matter in the form of compost (no sludge/ biosolids) or well aged animal manure. Yes, worm castings work well here too! Here’s a couple of links that should help you get off to a good start:
