Make particle interact with colliders

I have a particle that is basically a bunch of leaves (i think that is the name, correct me if i am wrong) that fall in a smooth way and interact with the wind, making the illusion that leaves are falling from the trees of my game. The problem is that when they hit the ground, they pass through it, completely ignoring the terrain’s collider.

Is there a way to make the particles hit the ground and stay there for a while WITHOUT bugging it? My leaves are very smooth and i want them to stay that way.

Unity’s built in particle system already supports collision. You need to look into the Collision Module that is already on your particle systems.
