Re: Clematis

Hi Lorraine
 
You don't say which Clematis you are growing but:
 
I have the same problem on my Clematis armandii, but it seems to recover when the weather cools and we get some rain. the problem for me seems to be made worse if I neglect to keep them moist enough at the roots, but whatever I do one or two shoots usually go black each year. I asked on this list about C armandii last year because of that problem and have followed advice given which was to grow in a container, roots in the shade and shoots in the sun. Since I don't spray if I can help it I have not used anything chemical to try to cure it. My mature C armandii now has enough shoots to suffer one or two losses and still perform for me in the spring.
 
Mind you if you think mites are sucking maybe our problems are different. Or you may have the dreaded Clematis wilt, which is a fungal problem. In my experience in England I found that the plant would recover from its roots. I have not experienced 'wilt' here in Crete.
 
 
Besides C armandii I grow several troublefree cultivars such as C.maximowitziana - which is absolutely stunning in flower now. C.texensis Duchess of Albany and Gravetye Beauty. C. integrifolia rosea, C x Betty Corning. These seem to suffer from no problems at all.
 
Nice to see you posting on the list. Hope you are well.

Subject: Clematis

Could someone give me suggestions as to what to do about all my Clematis plants are that are turning black.  I think mites are sucking the leaves, but when I sprayed one plant it died within a few days so I am afraid to spray again. I'd like to know how to get rid of the mites and save the Clematis. It seems like this is a problem I have every summer, but this year it is so bad I am afraid the plants will not revive.  Thanks for your help.
