As part of my other question, I started uprooting dandelions. How successful, exactly, in removing the root, I'm not sure.
Assuming that I am not always extracting 100% of the root, what can I put in the dug-up "grave" to prevent or stunt future dandelion growth? For example, if I put salt, it's not likely the dandelion will grow back -- but neither will anything else! (I plan to eventually grow something.)
So, what can or should I be putting in here? Is grass seed "okay" or "good enough?" Is there something benign that will compete with dandelions?
Chemicals are a no-go -- I have young kids who play in the backyard, and in my area, they just banned a whole slew of lawn chemicals.
