Hawaii’s climate supports a vibrant ecosystem, and homeowners can enjoy colorful, exotic plants in their own backyard. Although the tropical environment is mostly self-sustaining, routine landscaping and tree care services will help your greenery withstand natural hazards. Use this guide to learn about a tree’s biggest threats and what to do if you encounter them.

What Can Kill a Tree?

1. Harsh Weather

Heavy rain and wind can damage trees beyond recovery, especially if they’re weak or young. Weather varies across the state, but inland homes tend to experience heavier rainfall than houses near the shore. If your property is by the ocean, your trees are more exposed to hurricanes and tropical storms. Additionally, while lightning strikes are rare, they can be fatal to trees.

2. Fungus

Fungal diseases, like algal leaf spots and powdery mildew, can be fatal to trees and are likely to occur during periods of consistent rainfall. Rapid ohia death is a type of fungus that has spread between the islands since 2014 and is becoming a growing concern for residents. Phytophthora katsurae is another prominent example and mostly affects coconut palms.

3. Pests

Some woodboring insects will destroy trees over time, while others spread fungal spores on their wings and legs. In both cases, applying an insecticide will help contain damage or prevent it from occurring. In particular, the scolylinae beetle population has erupted in Hawaii and can be a significant threat to trees.

4. Bacteria

Bacterial leaf blights and spots make a tree lose its leaves, which compromises its ability to photosynthesize and produce food. Most cases of bacterial infections can be treated, but without the appropriate tree care, plants that lose too many leaves will probably die.

5. Root Rot

If the roots are too wet or the tree is planted too deeply, the trunk and roots will start to rot. Before it becomes fatal, root rot is characterized by cankers, stem girdling, and yellow leaves. You can prevent root rot by working with a professional arborist when planting trees or taking steps to facilitate soil drainage.
