Are these fruit trees that are infected?

Black Knot is most commonly found in fruit trees such as plums and cherries and less commonly peach and apricots.

I would recommend having a qualified Arborist examine the trees and shrubs to determine the exact fungus or disease your dealing with.

Contact your local County Extension Office for a referral of a qualified professional.

Here is a link to help locate your closest office and some more information on Black Knot.
