Leaf Spot
Leaf spot is one of the most common magnolia tree diseases and is caused by a fungus that attacks the leaves. Symptoms include brown or black spots that appear on the leaves, which can spread and cause the leaves to drop prematurely. This issue is mostly aesthetic and generally does not cause serious health problems, however it can persist and be a sign the the tree lacks the proper nutrients.
Treatment: Healthy trees are less susceptible to diseases like leaf spot, we recommend applying a Bio-Stimulant twice per year to keep your magnolia tree happy and healthy.
Wood Rot
Wood rot is caused by a fungus that attacks the bark of your magnolia tree. One of the most common symptoms is fruiting bodies (or mushrooms) growing on the trunk of your tree. To prevent wood rot, ensure your trees are pruned properly and at the right time.
Treatment: Infected wood should be removed to prevent the spread of fungal spores and prevent healthy areas of the tree from becoming infected. RTEC Treecare then applies a fungicide to the remaining wood.
Root Rot
Unlike wood rot, which sometimes does not show symptoms other than fruiting bodies, root rot comes with various symptoms, including reduced growth and vigor, dieback in the crown, and fungal growth at the tree’s base. Root rot is caused by fungal pathogens that enter the roots of the tree, usually due to the tree being in less-than-ideal conditions. Poor drainage, wounding of exposed roots, wet soil, and poor planting technique can result in root rot.
Treatment: Unfortunately, root rot is generally not curable, so prevention is key. Have one of our certified arborists evaluate the tree to determine if Root Rot is present and if there is a possible treatment.
