PHOTOS ARE HELPFUL - Tips for Submitting Pictures

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.
