Does a grass path block spread grass to adjacent dirt blocks?

Question

When a grass block is turned into a grass path block with a shovel, does it continue to propagate grass to adjacent dirt blocks, or is the grass then "dead"?

Answer 1

I have run an experiment and grass path does not spread grass to dirt.

Setting the random tick speed to 1,000 meant that things like wheat growing or grass spreading in this case are a lot faster with the default being 3. I suspect this is because the two blocks are stored differently. Grass is minecraft:grass whereas path is minecraft:grass_path.

Answer 2

No. Grass paths will not spread grass, which means you can keep the area barren if you want to.
