Plant Doctor: Disease ID

Plant disease identifier and plant doctor. Photograph a sick plant to diagnose the problem and get the treatment. DIAGNOSE PLANT DISEASE FROM A PHOTO This plant disease scanner identifies fungal, bacterial, viral, pest and environmental causes from the affected leaves, stem or fruit. It covers powdery mildew, blight, rust, black spot, botrytis, leaf spot, canker and root rot. WHY ARE MY LEAVES TURNING YELLOW? The pattern matters more than the colour. Yellowing on the lowest leaves usually means nitrogen. Yellow between green veins points to iron or magnesium. Soft limp leaves with wet soil is overwatering; crisp edges with dry soil is underwatering. OVERWATERING OR UNDERWATERING Both end in wilting, which is why they are confused. Overwatering kills far more houseplants than drought does, largely because the response to a wilting plant is to water it. PESTS AND DEFICIENCIES Aphids, scale, mealybug, spider mite and fungus gnats are covered, along with the leaf patterns that indicate nutrient deficiencies. Works on houseplants, vegetables, fruit trees and ornamentals.
