I do it manually! I'll usually start by doing a top down projection of the base texture (grass here) and then add from there. You can make quads pretty easily by dissolving edges. That's how I set up the paths with the grassy edges.

It's much easier to get organic looking shapes with a hex grid. Even with minimal tweaking I find the environment to feel much less rigid than one made from quads.

I learned it from Hyrule Field 😁
You have to turn on the "Extra primitives" addon and then the option is called honeycomb when creating a new mesh.
