Q: I have a lovely small pear tree which produced good fruit (unfortunately every single one eaten by squirrels.) Suddenly all the leaves have gone yellow to black - from the inside of the tree to the out...and they are all falling off. It's very sad and it's obviously got some kind of infection. Can you advise me what to do? Thank you very much.
Your tree probably has some sort of fungus, but it could have other problems you can't see. Call a tree doctor - a certified arborist for and on site inspection . You can find one in your area at www.isa-arbor.com .. Happy Yardening, Nancy
