The magnolia tree's large, waxy, green leaves contrast with its lovely, fragrant white blooms. They are ideal for sunny landscapes because of their conical, towering shape, which offers much-needed shade during the hot Westlake season.
Algal leaf spot is a deadly tree disease that, if left untreated, can cause irreparable damage to our lovely magnolias. Unfortunately, magnolia trees are highly susceptible to it.
Here, you can find out why you need Westlake tree care professionals to diagnose and care for your trees.
What is Algal Leaf Spot?
When it comes to organisms that cause Westlake tree diseases, plant parasites are not usually the first thing that comes to mind.
Cephaleuros virescens, which causes algal leaf spots or green scurf, is a common species in the U.S. This tree disease affects more than 200 different kinds of plants. Still, it primarily affects trees with thick, leathery leaves, like hollies, camellias, and magnolias.
The best conditions for algal leaf spots are warm, humid weather and soils that don't get enough air. Most likely to get hurt are plants already weak from other environmental stressors.
How Does Algal Leaf Spot Spread?
Sporangia, asexual reproductive structures, develop on host plant leaves in summer and produce spores dispersed by rain, irrigation, and wind. Secondary reproduction takes 8-9 months after infection.
This disease cycle favors warm, wet weather and stressed plants.
Symptoms of Algal Leaf Spot on Magnolia Trees
Algal leaf spot affects leaves, twigs, branches, and fruit. Magnolia trees with algal leaf spots:
Circular or blotchy spots that are raised, wavy, and resemble cushions.
- Spots may have feathered or wavy edges.
- The hues of spots range from grayish green to greenish brown.
- Due to the presence of reddish, spore-producing structures, the spots on the undersides of leaves turn velvety with reddish-brown hair-like structures in the summer.
- Many colonies can cause leaf yellowing and early leaf fall.

How Does Algal Leaf Spot Affect Magnolia Trees in Westlake?
Algal leaf spot affects tree leaves first. Untreated, it can reduce photosynthesis, cause defoliation, twig dieback, tissue necrosis, and kill Westlake magnolia trees.
The plant's twigs and branches are the most damaged. The parasite enters bark cracks, thickening the infection site. Over time, cankers form, girdling and killing tree branches.
Algal Leaf Spot Treatment
If your magnolia trees have algal leaf spots, call an ISA-certified arborist. Early detection is key to minimizing damage and saving your tree.
Professional pruning removes infected areas to prevent disease spread to new leaves, twigs, branches, and tissue. In addition, diseased plants should be destroyed to avoid applying to nearby trees.
Pesticides may be needed depending on the infection's severity. Trust an ISA Certified Arborist to maximize treatment effectiveness. This will prevent further damage to your tree and ensure the proper application and timing of disease management techniques.
Algal leaf spot attacks trees weakened by environmental stressors and poor growing conditions, so mitigating these causes through routine tree care and improving soil is key to managing tree diseases.
