It is wrong to turn plants around

ah ha - i think i've got it! the sun moves around them if they stay in
one place. if you move them - and i guess you have to keep moving them,
the sun on them wouldn't be even???

Hi Robin,
Probably the best known example of sun tracking (phototropism) in plants is
Helianthus spp. Here I have also seen it in A. belladonna. However, if you
are a cactus and planted during the sunniest, warmest time of year here, you
would experience enormous sunburn damage. In the better nurseries, cacti are
almost always marked on their south side.
