  • While looking at photos is not the best way to diagnose plant diseases, we will provide you with the best interpretation of what may be happening to your plants based on photos that you provide.
  • Take a variety of pictures. These should include:
    • Landscape shots. These sorts of photos show how your diseased plant is situated in your yard relative to other plants, buildings, driveways, sidewalks, etc.  They can often provide clues on environmental factors that may be contributing to the disease problem you are seeing.
    • Whole plant shots. These photos will show the distribution of symptoms on the plant.  Are the symptoms in just one area?  Are they scattered throughout the plant?  Is the entire plant affected?
    • Close up shots. Take pictures of affected leaves (both tops and bottoms), branches, roots, fruits or any other affected plant part.  We need to look for symptoms (e.g., leaf spots, cankers, discolorations, growth distortions, etc.), as well as signs of pathogens (e.g., fungal sporulation) that can help with diagnosis.
  • Take high quality pictures. This means taking:
    • Crisp, non-fuzzy photos. If a picture is fuzzy, we won’t be able to see much or tell you much.
