Tree Care in Hawi, HI

If you're looking at the trees around your Hawi home and feeling concerned, you're not alone. Most of the issues we see here, from cracked driveways to sudden branch drop, started decades ago when builders or previous owners planted the wrong tree for this specific place. Fast-growing species like Albizia, chosen for quick shade, now tower over properties with brittle wood and invasive roots. Ironwood trees, planted as windbreaks, can become hazardous in our year-round growing season as they outgrow their space. The good news is your mature Kukui or Hala trees have real, quantifiable value, and with proper care, they can be assets, not liabilities, for decades to come.

Why Tree Care Matters in Hawi

Professional tree care here is about more than just trimming. It's about risk management and preserving value. Our very hot, humid climate with 72 inches of rain means fungi and pests are active all year. A certified arborist can spot early signs of Rapid Ohia Death in your native Ohia or damage from the Erythrina Gall Wasp before they become catastrophic losses. For older properties, a professional assessment using industry-standard methods can determine if a towering Albizia is a $20,000 asset providing shade and stormwater control, or a liability threatening your home.

Your Tree's History

Many Hawi homes were built in the 1980s and 90s, right when fast-growing, non-native trees were popular in landscaping. This means the trees on your property are now roughly 45 years old, entering a critical maturity phase. Species like Strawberry Guava, planted for privacy, have likely become invasive thickets. The Albizia planted as a sapling is now a giant with a shallow root plate, a major concern in our wet soil. This era of planting decisions directly dictates the pruning, support, or removal choices you face today.

Active Tree Threats in Hawaii County

Rapid Ohia Death (ROD) critical

Rapid Ohia Death (ROD)

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 Hawaii 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 Hawaii 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.
