I have had a terrible fungal prioblem in my garden this year. I thin
its mainly powdery mildew that has affected my clematis, of which
have had to cut down about 5. It has also affected my honeysuckle, m
continus coggygria or "smoke bush" my rhododendron, and about 3 of m
other shrubs.

I have read that in clematis it can be caused by too much darkness an
moisture, but then in the same breath that it could be caused b
dryness at the roots, what am I to believe? At the time I was givin
them a thorough watering so believed it to be over watering. All I ca
do it cut all these plants back hard and hope it doesn't come bac
again. It seems to be an epidemic

If it is really powdery mildew, then it's really more of an aesthetic
problem than it is deadly to your plants. Cutting back isn't really
necessary. The spores are in the air and high humidity and high temperature
tends to encourage powdery mildew. Google "powdery mildew treatment" and
you'll see all sorts of chemicals and organic cocktails.

Google powdery mildew and milk and you will
information on how to control it and the ratio of
milk and water to use. You can also kill it with
JMS stylete oil.
