You may know that Ridgefield, Connecticut’s damp, cool weather creates a conducive environment for various types of tree fungus issues. As the expert provider of tree services in Ridgefield, CT, Frank’s Arborcare LLC is well-versed in these destructive tree diseases. Below, we outline some of the most common varieties of fungi in the area.
#1 Geosmithia Morbida
Let’s start with a canker disease that sometimes plagues our treasured black walnuts in Ridgefield, Connecticut. Your black walnut thrives in sunlight and soil that stays on the drier side. This state’s damp conditions sometimes make that environment unlikely, and stressed black walnut trees that succumb to excessive moisture could contract Geosmithia morbida.
More commonly known as Thousand Cankers Disease, this fungal infection comes from bark beetles. The pests transfer the fungus to weakened specimens, and as it spreads, you might see yellow leaves, noticeable trunk cankers, and defoliation.
#2 Powdery Mildew
Powdery mildew comes from the Erysiphales fungal order. It can overtake all kinds of tree species, but especially:
- Dogwood
- Maple
- Ash
- Oak
You’ll recognize it by the dusty, white powder on the affected leaves. It hardly ever kills a healthy tree, but the powdery film looks unsightly.
#3 Leaf Spot Fungi
Numerous fungal genera can cause a leaf spot fungus. It’s among the most common types of tree fungus issues, and you’ve probably seen it before.
Typically, the leaves of infected specimens develop small brown spots with a light center. There is a brown ring surrounding it, followed by a yellow outer ring. The more the spots appear, the less photosynthesis the leaves can perform, so saplings, recently planted trees, and already weakened specimens suffer.
#4 Polypore Fungi
Bracket fungi take on a more recognizable form: fan-like bodies attached to tree trunks and limbs. The fan-like formations have gradient bands of brown and beige, which look similar to turkey tail fungi.
Bracket or polypore species typically only infect tree hosts with wounds that give the fungus easy access to the heartwood. These fungi consume the weakened or dead wood, causing structural instability in the trunk.
#5 Phytophthora
Phytophthora, more commonly known as root rot, destroys numerous evergreen species from the roots up. Since it begins by attacking the root system, the fungus doesn’t yield noticeable above-ground symptoms for a long while. Eventually, you may notice:
- Clusters of browning needles
- Oozing cankers
- Poor growth
Trees can die from root rot without treatment. They need extra nourishment to recover.
How To Treat All Types of Tree Fungus Issues Successfully
Mature, healthy trees can usually combat fungal infections on their own. However, young or sickly specimens need help.
A local arborist can diagnose your infected trees and identify fungicides or additional measures that could help you treat them. Sometimes, it’s as simple as implementing better drainage near the tree. Other times, the specimen needs removal, so don’t wait to call an expert.
