Fungal & Foliar Disease Management
Clues in the Canopy. Fungal and leaf diseases can vary from unsightly yet harmless, to difficult to see and detrimental. We provide targeted applications to break the disease cycle and create more robust trees.

Needle Cast
If there are Colorado Blue Spruce trees in your area, there’s a very good probability you’ve seen Needle Cast (Rhizosphaera) at work. A fungal disease affecting coniferous trees, needles discolor, turning orange/brown and dropping. Die-back happens over a year so we often see fresh, healthy needle growth in the Spring on the “outside” edges of the canopy, with dying or dead needles just behind it. This results in the tree appearing skeletonized back to the trunk.
The best treatment for infected trees is yearly fungicide sprays, however some spruce and pines are less susceptible and, if overall healthier with good soil, water, and placement, will resist the fungus. Ask our team about what evergreens are top choices for our region.

Black Knot
A fungal disease that causes galls, bulbous black or dark brown growths in trees. Carried by wind, this disease can be prolific in a community. Treatment includes pruning and fungicide treatments to remove and prevent the fungal infection in susceptible trees like cherries and plums.
Our Compost Tea™ soil amendment can help bolster a tree’s ability to fight off the spread of infection. (Learn more about Compost Tea™)

Powdery Mildew
Appearing white and powdery on exposed leaves, this mildew can be problematic for weak or susceptible trees and plants.
Proper pruning for air circulation, removal of infected leaves after leaf drop, and in some cases fungicide treatments, are go-to control methods.
-
Tar Spot
Sycamore trees and maple trees of any variety often have unsightly black or dark brown spots across their leaves, appears from late Spring to Fall. While not pretty, this fungus is generally harmless, considered a cosmetic issue to a mature and otherwise healthy tree. The fungus will overwinter in infected leaves.
Like Powdery Mildew, proper pruning for air-circulation and clearing out infected leaves after leaf drop are good preventative measures for preventing re-occurrence in the Spring.
