Trees are vital to our environment, providing oxygen, shade, and aesthetic appeal. However, they are also vulnerable to various diseases that can weaken or even kill them. Understanding common tree diseases can help you take proactive steps to maintain tree health. Below are some of the key diseases to watch for.
Dutch Elm Disease
Dutch Elm Disease is a devastating fungal infection that spreads through elm trees via beetles. The disease blocks water flow within the tree, leading to wilting leaves, branch dieback, and ultimately tree death. If you notice yellowing or curling leaves in summer, it may be a sign of infection.
Ash Dieback
Ash Dieback is caused by a fungus called Hymenoscyphus fraxineus, which affects ash trees. The symptoms include leaf loss, blackened shoots, and bark lesions. Unfortunately, this disease spreads rapidly and has already killed many ash trees across the UK.
Oak Processionary Moth (OPM)
Although OPM is an insect-related issue, it significantly affects oak trees. The larvae strip trees of their leaves, weakening them and making them vulnerable to further infections. Additionally, OPM caterpillars pose health risks to humans and animals due to their toxic hairs.
Honey Fungus
Honey Fungus is a common yet deadly disease affecting many tree species. It spreads underground through root systems, causing decay and killing trees from the inside out. Symptoms include honey-coloured mushrooms at the tree base, white fungal growth under the bark, and rotting roots.
Powdery Mildew
Powdery Mildew appears as a white, powdery substance on leaves and stems, affecting a tree’s ability to photosynthesize. While not usually fatal, it weakens trees over time, making them more susceptible to other diseases.
