I have found this to be true but much more so if the sand is too fine. for
example the capilliary action sand exercises in wet seasons can cause
bacterial rot on Oncocyclus Iris. However, an insulating layer of gravel
top dressing usually gets round this problem and, for most other plants I
have grown, it is not an issue -provided the sand is coarse enough.
