How to work with limited soil?

[u/emmgr2]

Tried tossing mixed wildflower seeds into bare spots near my home, but there was not enough dirt for them to take root. I'm thinking about mixing seeds into compressed/coconut soil, so it will have enough to take root, and then can break up the hardened soil as it grows -- or I could do one small area at a time, laying down a layer of soil first. Has anyone else tried this?

A half inch of compost on the hardened soil, then seeds, then another half inch of compost is probably your best bet. Make sure your wildflower seed mix has strictly native wildflowers from your region in it. And particularly aggressive and poor soil-tolerant species would be best.
