Hawaii is known for its lush and beautiful greenery. However, their tropical trees are at risk from three common diseases. According to Ohana Tree Services, a top tree service company in Honolulu, the native foliage is at risk of Rapid 'Ohi'a Death, Koa Wilt, and Black Spot. These three diseases can cause extensive damage to their environment if not controlled.

Common Hawaiian Tree Diseases

Rapid 'Ohi'a Death

The native 'ohi'a is the king of all Hawaiian plants, as it makes up approximately 80% of the islands’ forests. Though it’s known for its resilience, it can suffer quickly at the hands of a specific disease. Rapid 'Ohi'a Death is a common, overwhelming illness that has spread to over 34,000 acres on the Big Island. It’s the cause of around 26% of annual 'ohi'a tree deaths each year.

Koa Wilt

The Acacia koa is another tree native to the island. Younger sprouts, those less than 15 years old, are most susceptible to a disease called koa wilt. When infected, they can lose their canopies and die within just a few months. 

Black Spot

Papaya trees are another common growth on the islands. They are subject to the black spot disease through a specific fungus called Asperisporium caricae. One could spot this disease through the water-soaked markings on the surface of the tree's leaves. On the underside, small, black spots grow. They might also be apparent on the fruits themselves. This disease can destroy the edibility of the papaya and even kill the entire tree.

Multiple beautiful trees grow on the Hawaiian Islands. At the same time, a number of diseases threaten their health. One of the best ways to keep plants healthy is to invest in professional care. Clearing, stump removal, and pruning can all help remove diseased portions. If you’re looking for a tree service company, call on Ohana Tree Services.
