Square pots or round?

I prefer round as they are generally more robust. Square pots are used by supermarkets and horticulture these days as when filled with soil they are relatively strong however they often break when you try to get the plant out.

In life and in nature the round is used more than the square as this shape is stronger and more flexible. Take the famous iron bridge for example the decorative circle shapes below are about strength as the circle will hold more weight than a square and give while still holding onto it’s shape.

A square is a weak shape unless it is combined with many other squares for support. I would imagine the round vessel originated from man using nature, gouging out logs to create bowls etc. Then the first pottery used clay over moulds so again a round or a cylinder shape was created as that is what nature gave us to work with. The square these days is about cost, you can get more square pots into a square crate for transportation. Simple logistics not design.

Round for me.
