Tree Care in Hana, HI

In Hana, your mature trees are more than just part of the landscape. They are a significant part of your property's value. Using the industry-standard CTLA method, a healthy, well-maintained Koa or a mature Hala tree is appraised for its species, size, and condition, adding tangible worth to your home. The challenge here is that many of the trees planted when these homes were built are now 30 to 40 years old. That means your Kukui nut tree or your flowering Ohia Lehua is entering a stage where proactive care is critical to preserve its health and your investment against our humid climate and specific pests.

Why Tree Care Matters in Hana

Professional tree care here is about protecting your property from unique, island-specific threats. The most urgent is Rapid Ohia Death, a fungal disease that can kill the native Ohia Lehua tree in weeks. We also monitor for the Erythrina Gall Wasp, which distorts and weakens coral trees, and the Coconut Rhinoceros Beetle, which bores into palms. With over 70 inches of annual rain promoting rapid growth and decay, a weakened limb from an invasive Albizia tree can become a major hazard long before it looks like one. Regular inspection by someone who knows these signs is essential.

Your Tree's History

Most homes in Hana were built in the 1980s and 1990s, meaning the landscaping is now mature. This era saw the planting of many fast-growing, non-native trees for quick shade and privacy. Today, that legacy includes problem species like the brittle Albizia and the thirsty Ironwood, which are now large and potentially hazardous. The native Koa and Ohia planted then have also reached full size, making them more susceptible to stress from storms or drought, which can leave them vulnerable to pests. Your trees are at a pivotal age.

Active Tree Threats in Maui County

Rapid Ohia Death (ROD) critical

Affects: Ohia Lehua (Metrosideros polymorpha) - the most important native forest tree in Hawaii

Two Ceratocystis fungi that kill ohia trees by clogging their vascular system. Trees can die within weeks. Ohia forms 80% of Hawaii's native forest canopy - its loss would be catastrophic for the ecosystem.

What to do: Do not wound ohia trees. Clean tools between trees. Do not move ohia wood between islands. Report browning ohia to Hawaii Dept of Agriculture.

Erythrina Gall Wasp high

Erythrina Gall Wasp - active in Maui County, HI

Affects: Erythrina species - wiliwili (native), coral trees (ornamental)

Tiny wasp from Africa that lays eggs in erythrina leaves, causing severe galling that defoliates and can kill trees. Nearly wiped out native wiliwili trees before biological control wasps were released.

What to do: Biological control is the primary management. Remove heavily infested non-native coral trees. Support native wiliwili recovery - trees are slowly recovering thanks to biocontrol.

Coconut Rhinoceros Beetle high

Coconut Rhinoceros Beetle - active in Maui County, HI

Affects: Coconut palm (primary), other palms, potentially other plants

Large beetle (2 inches) that bores into the crowns of coconut palms to feed on sap. Damages the growing point, reducing coconut production and potentially killing the palm. A serious threat to Hawaii's coconut palms and palm-based landscaping.

What to do: Report beetle sightings or V-shaped cuts in palm fronds to Hawaii DOA. Remove dead standing palms and stumps where beetles breed. Traps are available from the CRB response program.
