The first rule is to keep the plants healthy and vigorous. This means
pruning them each year and keeping their root system moist especially in
their first two years.
If your plants do suffer form disease (pest or insect damage is very rare),
it will be one of three diseases - clematis wilt, mildew or more rarely slime flux.

Message: My Jackamani clematis died from a disease that does not match any of your descriptions.
The entire plant (in the middle of blooming) turned black and died.
I have read a letter from one other person describing this phenomenon.
Do you have any helpful information or advice?
