Tree Service in Honolulu, HI

Tree service in Honolulu covers more ground than most people expect in one city. Near the coast the climate is semi-arid: the airport averages about 16 inches of rain a year, most of it between October and early April. A few miles inland, Mānoa Valley gets rain almost every day, even in the dry season. A monkeypod in Kāhala, a mango on a Kalihi hillside and a stand of albizia at the back of a Pālolo lot grow at different speeds, fail in different ways and need different plans. Our work is about reading each tree and each lot correctly before anyone climbs.

What August 2026 taught Honolulu about its trees

When Lala passed the islands in mid-August 2026, the Honolulu Fire Department logged 147 reports of downed trees on Oʻahu by noon on Sunday, and the city later counted about 500 calls for tree debris removal. The trees that failed were a familiar list: albizia, with shallow roots and brittle branches; royal poinciana and eucalyptus, with brittle wood; yellow poinciana squeezed into small planting spaces; a century-old banyan at Punahou Square in Makiki; and ironwoods near Kapiʻolani Park. Rain had saturated the soil first, and trees planted in narrow strips lifted out of the ground. Earlier in 2026, Kona low storms had already knocked down large trees around the island.

The lesson for homeowners is not that every big tree should go. It is that the problems usually show before the storm: a heavy limb over the roof, two trunks splitting from one base, a canopy that has never been thinned, or a fast-growing albizia that was a sapling a few years ago and now stands taller than the house.

Palms and the coconut rhinoceros beetle

Coconut palms are part of almost every Honolulu yard, and they need more regular attention than shade trees. The Aloha Arborist Association's guidelines call for pruning coconut palms at least twice a year in developed areas, so that nuts and dead fronds do not fall on people, cars or roofs. Coconut rhinoceros beetle, first detected at Joint Base Pearl Harbor-Hickam in December 2013, has since damaged thousands of coconut palms on Oʻahu. Adult beetles bore into the crown to feed, new fronds can break as they open, and a palm can die if the growing point is damaged. Because beetles breed in green waste, mulch and rotting palm stumps, the state restricts how that material moves on Oʻahu and requires it to be covered in transport.

Street trees, exceptional trees and power lines

Two city rules come up often. Trees in the planting strip between the curb and your property line are street trees, and pruning, spraying or removing one without a permit from the Department of Parks and Recreation is unlawful. Trees on the city's Register of Exceptional Trees, chosen for history, age, rarity, size or endemic status, need an approved permit before crown or root pruning. We flag both before quoting. For lines, Hawaiian Electric says homeowners are responsible for trees affecting the service line to their house, and the utility can de-energize and lower that line on request so the tree can be worked safely.

What an estimate visit covers

• Each tree or palm: species, lean, dead wood, cracks, co-dominant stems and decay
• What lies underneath: roof, lanai, carport, walls, the neighbor's yard and the street
• Service lines and whether Hawaiian Electric needs to be called first
• Access on slopes, steps and narrow side yards
• Whether the tree may be a street tree or a registered exceptional tree
• What happens to fronds, logs, chips and the stump
• A written price for each tree, with nothing added without your approval

Honolulu is the center of our work, and the city itself is several different places for trees. Kalihi, Pālama, Moanalua and Salt Lake have older homes on hillsides and in former tuff cones, with mango and breadfruit in back yards. Makiki, Mānoa, Nuʻuanu and Pālolo sit in wetter valleys and on ridges, where trees grow fast and access can be steep. Kaimukī, Kapahulu and the streets below Diamond Head are drier, with tighter lots and lines running through the canopy. Kāhala, ʻĀina Haina, Niu Valley and Hawaiʻi Kai have larger yards, more palms and more salt air. Beyond the city we also work in nearby communities along the south and windward shores. What stays the same everywhere is the need to check for street trees, exceptional trees and service lines before any cutting, and each area page covers what we know about that place.
