it is wrong to turn plants around

Agreed with Alberto on this. It may do little or no harm to induce symmetry
in, say, an African Violet for aesthetic reasons, but in general it is best
to allow plants to grow to face the light as they please. This maximizes
their ability to photosynthesize. There is no way humans can better a
process that is controlled by the plants in this way.
Aligning a plant with the main available light source-- not necessarily
north or south-- is especially important for woody plants. A manzanita may
never adjust itself to a natural growth pattern if its nursery
directionality is "violated" when planted. This causes unnecessary stress
for the plant and usually looks strange to us as well.

Some? Rather all. This is why it is wrong to turn plants around to get a
"uniform" rounded appearance for Shows.
I don't know the English expression for this but with woody plants it is
most important to "respect the North" when transplanting or moving them
to
a different spot. Meaning, they should retain the same orientation with
respect to the cardinal points.
