Question: vegetable garden and oleander

I have some land in front of the house with an oleander hedge around it.

I was wondering if by planting vegetables (tomatoes, salads, artichokes) nearby, the poisonousness of the oleander is not also transmitted to the vegetables themselves?


Answer: vegetable garden and oleander

Dear Giulio, thank you for contacting us through the questions and answers section of our site.

Oleander is one of the most poisonous plants as it contains in different areas (leaves, seeds, stem) alkaloids, oleandrin and cardenoids, toxic substances capable of inducing tachycardia, gastric disorders and central nervous system disorders. Even after drying, various toxic principles can be preserved that can cause serious disturbances to humans and animals that ingest them. Death occurs in most cases from heart failure after a high intake; most frequent victims of this plant are usually horses and goats.

The poisonousness of the oleander is not transmitted to the vegetables in the sense that it is practically impossible that the vegetables that are in the vicinity of the oleander absorb the harmful substances of the plant and also become poisonous even if given the high toxicity of the plant it is necessary to pay some attention.

Having said this, it is always better to avoid playing with fire and it would be advisable not to mix vegetables and poisonous plants in the same areas of the garden, both for general prevention and for common sense. At the limit if we really want to grow vegetables under an oleander plant it is advisable to cover the vegetables with a transparent PVC sheet, even if frankly, but this is a personal advice, we would change the area to grow our vegetable plants. Finally, popular wisdom also recalls through numerous sayings how in the vicinity of the oleander other plants tend to succumb.
