How do rocks help with drainage?

Lining drainage ditches with rocks creates a drainage system called French drains. The rocks are used to allow for greater drawing of water from the source area where the water was pooling. The water will flow into the rocks instead of being absorbed into the surrounding soil.

Then, do rocks improve drainage?

Rocks don't improve drainage; instead, they elevate the perched water table closer to your plant's roots. The plants end up sitting in too wet soil, increasing the chances of plant root rots and you've wasted valuable pot space with gravel that's doing no good.

how do you lay drainage rocks? If your soil drains well, you can simply dig the trench and cover the bottom with 3 to 4 inches of 3/4-inch drainage rock, depending on the depth of the trench. Even if you lay a waterproof base in the bottom of the trench, drainage rock is also important.

Hard rocks such as granite or river gravel prove viable options for a French drain because they won't break down over time as much as other rock varieties, such as sandstone and limestone.

Is Gravel good for drainage?

Gravel is an ideal drainage solution for two primary reasons — weight and an impenetrable surface. The weight and coverage area provided by the material prevents erosion, and its solid, moisture-resistant design allows water to drain faster. As such, it prevents precipitation from pooling on the surface.
