Why are the leaves of my pear tree turning brown (pic)?

HI Heather,

This looks like it may be pear scab, similar to apple scab. I would head to a local greenhouse that specializes in trees and see if they have any suggestions for you.

Sorry I couldn't be more help. Good luck. Lauren - The Little Lake Cottage

Hi Heather, here's some info that may help you out: http://fruitandnuteducation.ucdavis.edu/fruitnutproduction/Pear/Pear_Pests_Deficiencies/Pear_Diseases_Disorders/

Could be leaf spot or pear scab, both are fungal infections.... most organic gardeners use a copper fungicide for this. Read this on maintaining the trees, I like to remove the leaves by hand or prune the branches off.... dip your shears in bleach water to make sure you don't spread it.... https://www.planetnatural.com/pest-problem-solver/plant-disease/bacterial-leaf-spot/

Hi Heather, hope this helps you out. Brown, shriveled or black leaves indicate the presence of fire blight, caused by a bacteria that affects apples and roses too. You'll also see twigs and stems with a sharp elbow curve, and bumps or sores on the trunk, called cankers.
