Q. Who is Mr. Smarty Plants?

Title: Black leaves and dying kinnikinnick (Arctostaphylos uva-ursi)
Answered by: Nan Hampton

QUESTION:

My kinnikinnick has developed dark leaf spots and, in some cases the entire leaf has turned black or entire plants have turned black and died off. I'm worried about leaf spot, root rot and leaf gall as possibilities. My local plant spray services professional suggested it's a type of fungus which hasn't been identified yet. How do I figure out what this is and stop the spreading?

ANSWER:

Despite his name, Mr. Smarty Plants doesn't know everything, but does know how to get you to someone who should be able to help you. Mr. SP could speculate on what the problem with your Arctostaphylos uva-ursi (kinnikinnick) is, but I think it would be more efficient and more useful to you to contact someone in your area that has more practical experience with the plants and might have seen this problem already.

There are a couple of good sources for questions concerning plants native to the Northwest. One of the best is the University of Washington Botanic Gardens Elisabeth C. Miller Library Plant Answer Line.

Also, your Washington State University Pierce County Extension Agent Master Gardener's program has Ask a Master Gardener.

Good luck with your kinnikinnicks and may they soon look as healthy as those pictured below!
