Cedar Apple Rust

Cedar Apple Rust affects both your Cedar and Apple trees. Both trees are needed to support the conditions that cause this fungus to thrive. You may not have both of these species on your property, but your neighbors might have the other host. On your apple trees, you’ll notice the spotting on your leaves, and on your cedar trees you’ll see gelatinous galls from which orange spore horns will extrude in the rain!

Bug Busters will advise you on how to rid your trees of these issues. From pruning affected areas to applying fungicides, we’ll make sure your valuable trees get the treatment they need.
