My poor old potted Oleanders are looking a bit sick. They have been
wrapped in fleece in an unheated greenhouse all winter and haven't
been frosted, (the fuschias in there were OK). They are now outside in
a sheltered but sunny spot. The leaves look very tired and brownish. I
gave them a high nitro feed hoping that would perk them up but that
was 14 days ago. Still looking tired.

I have thoughts of potting them on but the roots have filled the pots.
Anyone got any suggestions?
