A friend has a problem with roses that live in large
pots outside the front door, next to a busy road.

For years they have flowered strongly, but this year a
lot of the leaves have turnedbrown and dry on the
outside, yellow in the middle, but remained green on
the central vein.

They are only very small leaves, and I did not have a
camera when I saw them. Not been able to find anything
similar by googling so far, so any one any ideas
please?


Phytophthora? Roses are susceptible.
