rocks or stones in bottom of large pot

Question

Do I need to put rocks or stones in the bottom of a large pot before the soil when planting in a large pot?

Answer 1

Proper drainage is important in any container large or small.
Drainage holes are generally adequate to allow the water to freely drain from the soil and container.

A few large rocks can be used to help weight a container, if the planting may be top heavy or wind may knock over a container.
