date palm

Question

At a lecture, the speaker said a “fact” that for date palms to produce quality fruit, the roots of the trees need to mingle together and a single tree does not produce (good) fruit. Can you verify if this is true? With any species?

Thank you

Answer 1

Though you do need male and female Date Palms for fruit production, I have not found any information about 'root mingling' for fruit to be produced.
Here are some links with more information.
