Tree Trimming in Honolulu
Nothing stops growing on Oahu. Trees that would be pruned every five years on the mainland need attention every one to three here, and coconut palms over walkways need it several times a year.
Call availability varies by area and time of day. Calls are answered by an independent tree service provider.
How often common Oahu trees need trimming
| Tree | Typical cycle | What is done |
|---|---|---|
| Coconut palm over a walk, drive or pool | Two to four times a year | Nuts, flower stalks and dead or sagging fronds removed |
| Coconut palm in an open yard | Once or twice a year | The same, less often |
| Royal, Manila and other ornamental palms | Once a year or less | Dead fronds only. Many shed on their own. |
| Monkeypod | Every two to three years | Dead wood, end-weight reduction on long limbs |
| Mango and avocado | Every one to two years | Height and spread reduction after fruiting |
| Plumeria | Every few years | Light shaping. Cuttings root easily. |
Why coconut palms are a liability question
A mature coconut weighs two to four pounds and falls from 40 to 80 feet. A full frond weighs considerably more. Either can seriously injure a person and will dent a car or crack a tile roof.
For that reason, hotels, condominium associations and most homeowners with palms over used areas keep them on a trimming contract. The interval is set by how fast the palm produces fruit, which depends on water and sun. Irrigated palms in Waikiki and Kahala fruit continuously.
Some owners choose to have palms over pools and entries replaced with non-fruiting species, or have flower stalks removed early so nuts never form. Both are reasonable ways to cut long-term upkeep.
Over-trimming palms
- The rule
- Leave fronds that are level or above. Remove only those hanging below horizontal, along with fruit and flower stalks.
- The hurricane cut
- Trimming a palm to a few upright fronds weakens it and narrows the trunk at that point, a defect that stays for life.
- Climbing spikes
- Spur holes in a palm trunk never close. Good crews use lifts, ladders or rope techniques where they can.
- Tool hygiene
- Saws should be disinfected between palms to avoid spreading disease.
Setting up a trimming schedule
Inventory
Count the trees and note which stand over places people walk, park or sit.
Set intervals by risk
High-use areas get the shortest cycle. Back-corner trees can go longer.
Fix the scope
Write down what is removed at each visit so companies can be compared on the same work.
Include green waste
Hauling is part of the job, and on Oahu the material should go promptly to an approved facility.
Review yearly
Trees grow, and uses change. Adjust the cycle.
Crown reduction and hat-racking
Reduction
- Limbs shortened back to a living side branch
- Natural outline kept
- Regrowth is moderate and well attached
- Repeated every few years
Hat-racking
- Limbs cut to bare stubs at a set height
- Dozens of fast, weak shoots from each stub
- Decay enters at every cut
- Needs redoing within a year or two, and the tree is weaker each time
In a year-round growing climate, a topped monkeypod or mango can be back to its old height in 18 months with far worse structure. Reduction takes more care per visit and far less work over a decade.
When to schedule
- Act now
Coconuts are visibly full-sized over a walkway
Trim now and shorten the cycle.
- This week
Hurricane season is approaching and big shade trees have not been pruned in years
Book dead-wood removal and limb reduction before June.
- Plan it
A mango has finished fruiting
Prune for size in the weeks after harvest.
- Plan it
A large old tree on the lot may be a registered exceptional tree
Check with the county before anything beyond light pruning.
Honolulu tree trimming questions
What decides how big a coconut trimming job is in Honolulu?
The number of palms, their height and the access to them. A regular schedule keeps each visit short. Get the scope in writing to compare companies.
Can coconuts be stopped from forming?
Removing the flower stalks at each visit prevents nuts from developing. On a regular cycle this keeps the palm free of heavy fruit.
Is it legal to trim a street tree in front of my Honolulu home?
No. Street trees are maintained by the city's Division of Urban Forestry. Ask the city.
Does a tree trimmer need a license in Honolulu?
Above the state's small-project exemption, yes, under the C-27b tree trimming and removal classification. Ask for the license and for workers' compensation coverage.
