How often does shaking grass appear?

Question

I would like to know this because I need a pansear

Answer 1

I've found the grass and water don't happen as often as the dust. But if you're patient, it will happen!

Answer 2

Not sure. Sometimes takes me a couple minutes, sometimes nearly ten. Just run along outside of the grass. It will force the grass to shake eventually. Same with water, bridge, and dirt in caves (although the caves one, it is recommended to use repels)
