Citrus Scab

Does your lemon tree have areas that look like warts or scabs? It could be infected by one of the common Meyers lemon tree diseases: citrus scab. Citrus scab attacks the leaves, twigs, and fruit of the lemon tree.

These citrus scab pustules can spread quickly. Trees are most vulnerable during the first three months following the fall of their blossoms. It's important to protect the trees during this time. Applying a copper fungicide regularly during this time will help protect the lemon tree.

Anthracnose

Anthracnose is a lemon disease that may affect your Meyer Lemon Tree. This disease causes the leaves to shrivel and turn dark in color. In just a few days after infection, anthracnose can turn a healthy, beautiful tree into a mess.

To control the spread, destroy any infected leaves and prune away any dead or damaged limbs.

Armillaria Root Rot

A common Meyer Lemon Tree disease is Armillaria root rot. Symptoms of this disease include yellowing leaves, a gradual decline in foliage, and white fungal growths under the bark that may produce an unpleasant odor.

Depending on how early the Meyer Lemon Tree is diagnosed with Armillaria root rot, it may not be possible to save the tree. Once honey-colored mushrooms appear on the bark, the disease is usually too advanced to treat.

Botrytis fungus

After Meyer Lemon Trees are exposed to long periods of rain, they can become susceptible to a disease called botrytis fungus. This disease appears as gray mold and can spread very quickly if not treated in time.

Wounded Meyer Lemon Trees are more likely to be affected, so be sure you’re taking proper care when pruning or handling the plant. Remove any infected areas immediately and thoroughly clean tools and surrounding surfaces between trees to prevent the infection from spreading to other plants.

Phytophthora Fungus

Another Meyer lemon tree disease to look out for is Phytophthora fungus. This fungus causes gummosis which is presented as a gummy presence on the surfaces of the lemon tree.

Phytophthora fungus lives in the soil. You will need to remove all infected fruit and leaves from both the tree and those that have fallen off the tree. You will want to follow up with a fungicide to further protect the tree from more damage.

Get Educated on Lemon Tree Diseases

I have a Meyer lemon tree that I bought at Walmart three years ago. It hasn’t gotten any bigger, and hasn’t successfully grown any new leaves. I keep pruning back to where there are leaves, but nothing seems to happen. The tree isn’t dead, but it’s like it’s in suspended animation. Is flowers once in the spring and is covered with flowers, but no leaves.
