Oleander Leaf Scorch

Posted by George J Janczyn on July 2, 2009

If you are considering Oleanders for your drought-tolerant landscape, be aware that many plants in San Diego suffer from an incurable, infectious disease called Oleander Leaf Scorch. Once infected, a plant may survive for years, but it inevitably deteriorates and dies. We had five on a slope in our Del Cerro back yard, they all became infected, and over a period of about four years we lost all of them.  The problem is supposed to be worse in hot inland areas, but I’ve noticed quite a few dying in the I-5 median along Mission Bay.  In Escondido along I-15 almost all the Oleanders in the median are reaching advanced stages.

    They get it up in the Bay Area, too. I would happily see a moratorium on planting it.
