I've got an Olive that's been on my south facing roof garden for a
couple of years and appears to have caught some kind of black spot.
The inner leaves are one by one developing small black spots. Maybe one
or two per leaf. Over several days the leaves turn light green then
yellow and fall off.
In March I did 'hide' it between two conifers for protection against
some heavy wind and rain for about 5 days (quite a shady damp place)
after which the symptoms appeared.

It's a healthy tree - doubled in size in 2 years (about 1m tall) and
has got many flower buds that are about to bloom.
With all this leaf drop (about 5-10% so far) I'm worried about it
lasting much longer.
Am about to treat with a fungicide (Dithane945) - is that a good idea?



Before doing anything make sure it's draining properly and that the compost
isn't waterlogged. I'm assuming it's in a pot so if that is the case, raise
it up on bricks or something and make sure the pot has adequate drain holes,
too. Damp and shade aren't olive friendly. Think of their normal habitat,
stony, well-drained and sunny!
