We visited Spain over Easter and discovered that our oleanders seem to be suffering from some sort of die back.  It starts with the leaves having brown spots, which then die and then seems to travel down the plant killing whole branches.  Any ideas?

Is it was some kind of fungus, you can get a fungicide at the garden center of any hardware store that will work. I think it can be caused by too much moisture in the soil, so if its been raining a lot where you live, that could be the problem.

Oleander grows well in warm subtropical regions, where it is extensively used as an ornamental plant in landscapes, parks, and along roadsides. It is drought tolerant and will tolerate occasional light frost down to -10°C . It can also be grown in cooler climates in greenhouses, conservatories, or as indoor plants that summer outside

Oleanders grow best in full sun and will tolerate even reflected heat from a south or west wall. They will tolerate partial shade, but may have a lanky, open shape.

Oleanders are tolerant of many different soil types, but must have good drainage. They will not do well in wet areas. Oleanders are very drought-tolerant once established, but respond well to occasional deep watering.

Thanks for your reply Simone.  The plants aren't in a particularly water prone area and have never suffered from any fungal problems in the 5 years that they've been planted.  Oleanders are such tough plants that it was a surprise to see them struggling.  We're returning in mid-June so we'll see if they've recovered by then.

If it were me then I would cut right back and remove all the bad, giving the plant chance to grow back to full glory, I had a few issues with mine and I cut everything off, it has grown back lovely - not that I particularly care for the Oleander with it being so poisonous - they worry me slightly so I now only have 2 as I killed the rest
