Yes it does sound like rust to me too which is identified by the orange
cirlcles and particularly affects pelargoniums. Control for rust is to spray
with zineb every 7-10 days or use wettable sulphur. Non-chemical : remove
infected leaves ASAP and do not apply excessive quantities of nitrogenous
fertiliser. From the pest disease book that I have called What Garden Pest
or Disease is That - Judy McMaugh. Hope you can fix the problem. Heather.

Can anyone explain why the leaves of my geraniums - some in pots , some
in
a
big letterbox planter - have taken on an orangish tone ?
Thanks Deb
