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.

Secondly, what type of rock is used for drainage?

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.
