We provide tree service in Glendora, CA, including pruning, removal, palm trimming, stump grinding and fire-safe clearance from Glendora Village and the streets near Citrus College up to Rancho Glendora, Gordon Highlands and the canyon neighborhoods. City trees in Glendora are managed by the Public Works Trees Division under the City's Urban Forestry Manual. For private trees, the City reviews impacts as part of discretionary development projects, and trees removed for those projects must be replaced. Call (909) 479-2666 to talk about your trees.
Glendora's tree rules
The City's Urban Forestry Manual sets the rules for City trees and explains how private trees are treated during development. In plain terms:
- City trees, including street and park trees, are maintained by the Trees Division. Do not prune or remove them yourself.
- Development projects that need discretionary approval, such as a Development Plan Review or a Conditional Use Permit, include a review of private trees on the site.
- Replacement. Oaks 8 inches or more in diameter and other trees 10 inches or more removed for those projects must be replaced on a size-based schedule.
- Native oaks are given special importance in the manual.
For ordinary yard work not tied to a development project, check with the City if a large oak is involved. We will help you understand what we see before you call.
Foothill homes and fire risk
Glendora's north side climbs right into the San Gabriel Mountains, and many homes in the foothills and canyons sit next to wildland. Dry brush, Santa Ana winds and steep slopes make fire safety a priority. Our defensible space service covers:
- Cutting dry grass and brush on slopes.
- Clearing dead palm fronds.
- Lifting limbs off roofs and away from chimneys.
- Removing ladder fuels under trees.
- Removing dead trees close to the house.
Check the State Fire Marshal maps for your address and ask the Los Angeles County Fire Department what clearance applies.
Trees we see in Glendora
- Coast live oaks, many of them very old, in foothill and canyon yards.
- California pepper trees, often huge, with heavy weeping limbs.
- Sycamores along washes.
- Eucalyptus and pines on larger lots.
- Citrus, reminders of Glendora's grove history.
- Fan palms and queen palms in newer landscapes.
Glendora Village
Around Glendora Village and Citrus College, neighborhoods are older and the trees larger. Typical jobs include thinning big pepper and camphor trees, removing dead pines, trimming palms and grinding stumps. Street trees are City trees, so check with the Trees Division before touching those.
Caring for old oaks
Many Glendora oaks are older than the houses around them. Light pruning in the cooler months, deadwood removal, keeping sprinklers away from the trunk and avoiding soil changes inside the dripline help them stay healthy. If an oak is declining, a tree health assessment is a good first step.
Wind and storms
Wind coming off the mountains can be strong in Glendora. Pepper trees, eucalyptus and pines lose limbs in big events. After a storm, call SCE at 1-800-611-1911 for anything near a line. For private trees, our storm damage service can help.
Nearby
Glendora borders San Dimas and La Verne to the east and Covina to the south. Pomona is a short drive southeast on the 57 or the 210.
Pepper tree care
California pepper trees grow fast, get very large and develop long, heavy limbs that can split, especially after heavy rain or in wind. Regular thinning and end-weight reduction keep them safer. Avoid topping, which causes dense, weak regrowth. Pepper trees also drop a lot of litter, so many owners like them thinned enough to reduce cleanup without losing shade.
Canyon access
Canyon neighborhoods often have narrow roads, steep driveways and limited parking. We plan around those limits, use compact equipment and coordinate parking with neighbors when needed. Material often has to be carried or roped up to the street.
Pricing
Foothill and canyon jobs take more time because of slopes and access. Flat lots near the Village are quicker. We give you a written estimate after we see the site, with each part of the job listed separately. Call (909) 479-2666.
Citrus and old grove trees
Glendora was once covered with citrus groves, and many older lots still have a few orange, lemon or grapefruit trees, sometimes very old. Light thinning after harvest, removing dead wood and suckers from the rootstock, and keeping the trunk dry and shaded go a long way. When a grove tree is hollow, split or mostly dead, removal and replanting with a young tree makes more sense than heavy pruning.
Dry seasons and young trees
Foothill soils in Glendora drain fast and dry out quickly in summer. Young trees planted in the last couple of seasons need regular deep water until their roots reach deeper soil. Water slowly, at the outer edge of the root ball and beyond, so roots spread instead of circling. A layer of chips over the root zone keeps moisture in and protects the soil from the summer sun. Mature native oaks are the exception, since they prefer to stay dry in summer.
Scheduling
Spring fills quickly with brush clearance in the foothills, and fall with wind-prep thinning. Book early if you want clearance done before the dry season starts.
Tell us if your street is narrow or parking is limited, so we can plan where the truck and chipper will sit.

Common questions
Who maintains street trees in Glendora?
The City's Public Works Trees Division maintains City trees, including street and park trees, under the Urban Forestry Manual. Report problems with a City tree to the City instead of hiring someone. For trees on your own property, call us, and we will look at the tree and give you a written estimate.
Do I need a permit to remove a tree on my Glendora property?
For ordinary yard work, the City's manual focuses on City trees and on private trees affected by development projects that need discretionary approval, where replacement is required. If a large oak or a project is involved, check with the City first. We can describe the tree's condition to help with that conversation.
