Thanks Lou
The Hippeastrums which are in the garden, have been there for some
years, so must be coping ok regardless of the bit of fungus. Will
experiment and see how it all goes in a years time.

Hi Ina,
Cinnamon is a commonly used fungicide among orchid growers. We use it
as a dust. In my experience it really works, though I can't say I have
made controlled scientific tests.
I am as skeptical of new age nonsense as anyone (probably more
skeptical). There is nothing unreasonable about expecting tree bark
derivatives to have antifungal properties. If you live in tropical
forests, one of the most strikinbg things you can observe is the great
variation in decay rates of different kinds of wood. Local people are
well aware of this and use only certain woods for contruction. Those
woods have real antifungal properties.
Cinnamon is just one tree derivative with antifungal properties.
Another is good old aspirin, based on willow trees. Orchid growers have
found that aspirin reduces mold and fungus when plants are watered with
a solution of it. I have found it useful and I have made some small
tests which suggest it is effective.
Having said all this, it sounds like you need a serious systemic
fungicide, and I would be surprised if anything less will help you...
Best,
Lou
