To keep your garden trees healthy, you should know about the most widespread tree diseases.
In most cases, knowing the first signs can help you prevent the damage and cure a tree without destroying it.
Here are a few illnesses you should know about.
Tree Fungal Infections
Fungal infections can damage trees and cause various symptoms like leaf spots, cankers, or wilting.
Some common fungal diseases include powdery mildew, root rot, and leaf blight.
Insect Infestations
Insects such as aphids, caterpillars, or borers can harm trees by feeding on their leaves, bark, or roots.
This can weaken the tree and make it more susceptible to other diseases.
Tree Rust Diseases
Rust diseases are caused by fungi that create rusty-colored spots or pustules on leaves and stems.
These diseases can weaken the tree and affect its overall health.
Tree Bacterial Infections
Bacteria can infect trees through wounds or cuts in the bark.
They can cause bark cankers, oozing sap, or discoloration of the wood, leading to tree decline.
Nutrient Deficiencies
When trees lack essential nutrients like nitrogen, phosphorus, or potassium, they can exhibit stunted growth, yellowing leaves, or poor fruit production.
Nutrient deficiencies weaken trees and make them more susceptible to other diseases.
Tree Viral Diseases
Viral diseases in trees are caused by pathogens that can be transmitted through infected plant material or insect vectors.
These diseases can affect the tree's growth and lead to leaf discoloration, stunted branches, or fruit deformities.
Tree Root Diseases
Root diseases, such as root rot or root collar rot, affect the tree's underground system.
They can cause root decay, poor nutrient uptake, and overall decline in tree health.
