I have been researching the question of growing vegetable crops where
oleander had been growing until recently. Both are from credible scientists.

Following is the Arizona response:
> Hi! The toxic alkaloids and glycosides in oleander should not be taken
up or accumulated from the soil by the vegetable crops. You need to
ingest oleander roots, stems or leave directly to be exposed to the
toxic substances. As the oleander roots decay in the soil, the microbes
will degrade these substances. So, unless you come in direct contact
with the decaying oleander roots, then there is little chance of
exposure. If you want to be particularly carefully for a growing season
or two, then avoid planting root crops and plant vegetables where the
leaves or fruits are harvested as food.

All parts of the oleander are toxic if eaten, but to my
knowledge oleander does not produce any toxin that would
get into the soil and then be taken up by vegetables and
Check the web for "oleander poison". Here is one site:
