Oleanders

[Sammy48]

This Summer the leaves on all four of my Oleanders are turning yellow and dropping off.

They are in large pots and get fed and watered regularly. I thought perhaps too much water so I tried that and not enough water so I started up again. Nothing seems to make a difference.

Last Summer they were fine.

Anyone know ?

Murray, they are in very large pots.

I always was led to believe that Oleanders were tough as old boots and could even be neglected.

[murraymints]

normally yes..but you may have had some weather issues..follow the potting advice in above link..

even if it is recomposting and same pot ^

This has got me wondering that, the plants may not be draining well enough. When the pots are watered, the water should be seen to disappear fairly quickly into the compost.
If the water puddles on top, it could indicate that the compost has become clogged.
If this is so, it may be worth re-potting and adding extra crocks or grit to improve drainage

as per my link..agree !

old bits of smashed pots or gravel/grits
