Trees add beauty to most any lawn, but if you start to notice your tree starts to look strange on its leaves or bark, it may be a sign of a tree disease. If a disease gets into the root system it can affect surrounding trees to catch the infection. If you are unsure if your tree has a disease, here is a list of common tree diseases

Even though it doesn’t cause much damage to the tree, it looks much worse. So it’s important to use fungicides that are harmless and natural to protect your plants.
#2. Leaf rust.
Leaf rust is a distinctive orange or reddish spotting on the leaves. This fungal disease can affect other plants as well as trees so it’s very important to take care of it ASAP.
