Palm tree trimming in Pomona, CA means removing the dead and dying fronds, the flower and fruit stalks, and loose old frond bases, while leaving the living green fronds alone. A well-trimmed palm keeps a full, rounded head, not a narrow "pineapple" tuft. Most palms here need trimming once a season, typically in late spring or summer after flowering starts. Call (909) 479-2666 and tell us how many palms you have and roughly how tall they are.
Palms we trim around Pomona
- Mexican fan palm (Washingtonia robusta). The very tall, skinny palms along many Pomona streets and back yards. Fast growing, often 60 feet or more.
- California fan palm (Washingtonia filifera). Thicker trunk, shorter, with a heavy skirt of dead fronds if left alone.
- Canary Island date palm. Huge, heavy crowns with sharp spines. Trimming takes care and the right tools.
- Queen palm. Common in newer landscapes. Messy fruit and fronds that brown quickly.
- Pygmy date and sago. Smaller plants near entries and pools.
What a proper palm trim includes
- Dead and hanging fronds removed at the base.
- Flower and fruit stalks cut before they drop seeds and attract pests.
- Loose frond bases (boots) cleaned off where they come away easily, without cutting into the trunk.
- Green fronds kept. We aim to leave the fronds from about the 9 o'clock to 3 o'clock line and above.
- Cleanup. Fronds and debris hauled away, including the sharp date palm material.
Why over-trimming hurts palms
A palm feeds itself from its green fronds and stores nutrients in older ones. Cutting off healthy green fronds to make the palm look neat starves it, can cause a narrowing "pencil" trunk over time, and makes the crown more prone to breakage. The University of California IPM program and palm researchers recommend removing only dead and dying fronds. Spikes should never be used to climb a palm you want to keep, since every hole is a permanent wound.
Rats, fire and other reasons to trim
An untrimmed fan palm grows a thick skirt of dead fronds that hangs down the trunk. That skirt is a favorite home for roof rats, and it burns very easily. During Santa Ana wind events, embers can land in dead fronds and spread fire. Cleaning off the skirt is one of the simplest defensible space steps for homes with palms near the roof. It also keeps fronds from falling onto cars, roofs and walkways in wind.
Palm removal
Sometimes a palm needs to go: it is diseased, too close to the house, under a power line, or simply too tall to maintain safely. We take palms down from the top in sections, lowering the heavy crown on ropes, then cut the trunk in rounds. Palms do not have a woody stump like other trees, but the root ball can be ground out. See stump grinding and tree removal for how we handle access and haul-off.
Palms near power lines
Tall Mexican fan palms often grow up through or beside overhead lines. If any frond is within 10 feet of a line, call Southern California Edison at 1-800-611-1911 before anyone climbs. SCE clears its lines, and once that is done, we can trim the rest of the palm. Our power line guide explains the process.
Street palms and City trees
Some Pomona streets are lined with palms planted in the parkway. Those are City street trees, and Pomona requires a written permit before anyone trims or removes them. Call the City at (909) 620-3759 about a street palm. For palms on your side of the sidewalk, we handle the work directly.
Diseases to watch for
- Fusarium wilt in Canary Island date palms, where fronds die on one side of the crown first. It spreads on pruning tools, so we clean or swap saws between date palms.
- Pink rot and bud rot, which attack stressed palms and can kill the growing point.
- Palm weevils, which have been found in Southern California and attack the crown.
If your palm shows dying fronds in the center of the crown, a tree health assessment can help decide whether it can recover.
How often to trim
Most fan palms here need a trim once a season. Date palms and queen palms may need it a little more often, because their fruit and flower stalks create a mess. Our palm care guide goes into timing, rats and frond counts. To book, call (909) 479-2666.
Pricing palm work
Palm trimming is priced per palm, based on height, species and how much dead material has built up. A short queen palm by the patio is quick. A Mexican fan palm with a skirt that reaches halfway down the trunk takes longer and produces a lot more debris to haul. Canary Island date palms take the most time, because the fronds are heavy and the spines are sharp. Several palms in one visit cost less per palm than booking them separately. Tell us the count and rough heights when you call, and we can give you a ballpark before the visit.
We trim palms all over Pomona and in nearby cities like Ontario, Montclair and Covina.
Common questions
How often should palm trees be trimmed in Pomona?
Most fan palms need a trim once a season, often in late spring or summer when flower stalks appear. Date palms and queen palms may need it more often because of fruit and stalks. Trimming too often or too hard does not help the palm, so we only take dead and dying fronds plus the stalks.
How many fronds should be left on a palm?
Leave all the healthy green fronds. A good rule is to keep everything at or above the horizontal line, from about the 9 o'clock to the 3 o'clock position. Cutting live green fronds starves the palm, weakens the crown and can make the trunk narrow over time.
Can you trim a palm that is next to power lines?
Not the part near the lines. If any frond is within 10 feet of an overhead line, call SCE at 1-800-611-1911 first. SCE clears its own lines with qualified crews. After that, we can trim or remove the rest of the palm safely.
