As awful as those algal leaf spots look, they’re not necessarily damaging your tree.

If you can bear the appearance and your tree is producing well, you can continue on with business as usual.

It might be a good idea to remove any debris or weeds around the trunks of these trees, as well as thinning the interior of the plant to ensure that maximum air flow is available to dry out leaves and bark.

After all, avocado algal leaf disease depends heavily on moisture to thrive. If younger trees or vital landscape plants are affected, treating spots on avocado leaves is easy.

Even though the existing spots will remain after treatment, you can prevent new spots from forming by thinning the tree and spraying it with a copper fungicide.
