The Master Gardeners will follow up via email with a request for photos.  Here are some tips:

If possible, please provide 3 digital photos that are clear and in focus. To avoid strong shadows, outdoor photos are best taken in the shade, overcast days, or when sun is behind a cloud. We recommend including:

1. Photo showing entire plant/plant group and its surroundings with overall pattern of the plant’s problem

2. Photo showing affected branches, preferably one with both healthy and discolored tissue. 

3. Close-up photo(s) of symptoms, for example centering on one or a few leaves/needles or the place where green tissue meets discolored tissue; or the areas of suspected insect damage (or the insect itself); an area of the trunk, branch, or twig bark you suspect of being abnormal, such as stem lesions, oozing, bumps, insects, white or other color objects.

Thank you for your patience while our Help Desk Team researches your question.
