Clematis leaves dry up


My Clematis leave all dried up? What might have caused the problem. Will this spread to other plants such as lily?
What kind of soil is good for clematis. I added some wood ash to the soil, is woo-dash good for clematis?I have attached a photo. Thanks for your help.



Thank you for contacting Toronto Master Gardeners about your clematis. From your photo, it is difficult to determine the variety and condition of the clematis you are concerned about. There are many clematis varieties, some more susceptible to problems than other. In general, clematis need well-drained soil rich in organic matter with a pH of 6.0 to 7.0, full sun to partial shade with a shaded root zone to keep the roots cool.

While wood ash can be beneficial for plants, being alkaline, it may raise the soil pH out of the range necessary for good growth of various plants.  Testing the soil pH would be helpful to ensure the pH of your soil is in the recommended range for clematis. It is recommended that you test your soil before amending. Much of Ontario is already alkaline soil. It is better to test first as you can not remove amendments once they are added. Here is a link for soil testing labs.
