Tree care in Walnut
Named for its walnut trees
Walnut takes its name from Rancho Los Nogales — nogales means walnut trees — and the city still protects oak and walnut trees by ordinance. It became a city in 1959 and sits between the San Jose Hills and the Puente Hills. Its City trees follow a strict policy. Topping, lion tailing and trimming for a view are banned. Median and parkway trees are checked every three years. Owners with a City tree in the easement over their lot must water it, clear its fallen leaves and report hazards. Harming a City tree can bring a fine of up to $1,000.
In Walnut, a City tree can grow on your land — and you are the one who waters it.
Who governs tree work in Walnut
City of Walnut
Tree work in Walnut follows the City of Walnut's rules. City-owned and City-maintained trees are managed under the City Tree Policy, which applies the tree regulations in Title 5, Chapter 20 of the Walnut Municipal Code to planting, pruning, removal and protection. Rules change. Confirm current requirements with the jurisdiction before work begins — filing a permit is the property owner's responsibility, not ours.

Walnut hillside lots get thinning, removals and stump grinding
Supreme Tree Experts thins crowns, removes trees and grinds stumps in Walnut, where oaks and walnuts are protected. Walnut owners leave the trees on their own lot, outside the City easement, to Supreme Tree Experts.
Tree Removal
We remove dead, split and unwanted trees from Walnut yards, lowering big wood in sections on sloped ground. City ordinance protects oak and walnut trees, so we name each species before any cut. You learn which ones need city approval first.
Tree Trimming & Pruning
Our crews prune yard trees here with thinning cuts that open the crown and keep its natural form. When the city thins native oaks, it takes no more than 10% of live growth. We hold your oaks to that same light limit.
Stump Grinding & Stump Removal
We grind stumps out of lawns and beds here, going below the soil so a mower passes clean. Surface roots near walks can be ground at the same visit. The chips go back in the hole or leave on our hauler.
Palm Tree Trimming & Skinning
Our palm crew clears dead fronds, flower stalks and fruit clusters before they drop on roofs and pools. Next comes skinning, which takes the old frond bases off the trunk. Our lift truck for palms puts the crew level with the crown.
Emergency Tree Service
Our crews answer storm calls 24/7 when a tree falls on a Walnut home, fence or drive. Big trees on sloped lots between the San Jose Hills and Puente Hills can tip toward houses in hard rain. We cut the load free and haul it off.
Tree Maintenance
We inspect and prune yard trees on a set schedule, so weak limbs and pests get caught early. The city inspects or trims its median and parkway trees every three years. Your own trees need checks between those city visits.
Tree Height Reduction
When a yard tree grows too tall, we shorten it by cutting back to strong side limbs. City tree policy here bans topping, lion tailing and trimming just for a view. We use the same approach at home, so the crown keeps its shape.
Estate Tree Care
We care for every tree on larger Walnut properties with one plan that runs across the year. Many of these lots climb the hillsides, with trees behind back walls. Our own 75-ft boom trucks reach over those walls, so crews stay off the slope.
Tree Shaping & Shrub Shearing
We shape shrubs and square up hedges so walks, drives and windows stay clear. The city expects owners to pull vines and keep weeds off any City tree in their easement. We tidy that ground while we work.
Landscaping
We plan planting and irrigation for Walnut yards with the trees in mind. Owners must water any City tree in the easement over their lot, and too little water counts as injuring it. So we run a line to that tree as well.
Hardscape
We build patios, paths and low walls that leave room for tree roots. City policy bars compacting soil or cutting into a City tree's drip line. We set new paving outside that zone, so the tree and the slab both hold up.

The questions worth asking any Walnut tree company
6 of them, answered here for Walnut. If yours is not here, call 877-787-7363 and ask.
Not without an approved request form. Walnut's code makes it unlawful to prune, root prune or remove a public tree. Ask the Community Services Department first. A business doing the work needs a current Walnut business license. Breaking the rule can bring a civil penalty of up to $1,000 per tree.
No. The city's tree policy lists reasons that are not valid for removal: leaves in gutters or pools, messy fruit, flowers that draw bees, shade and views. Hazards, building damage and hardscape damage that cannot be fixed without severe root cutting can qualify.
Water it and keep it tidy. Owners must water City trees in the easement, remove vines, clear fallen leaves and deadfall, keep weeds off the trunk area and report hazards to Community Services. Harm from too little water counts as injuring the tree.
Every three years. All median and parkway trees are inspected or trimmed on a three-year cycle. Young trees get a first trim within three years of planting. Residents are told before a City tree in front of their home is pruned.
Yes — $600 for tree services, wherever the job is. Hillside access, and whether a tree is an oak, a walnut or a City tree, shape much of the cost here.
Yes, 24/7. Big trees on sloped lots between the two ranges of hills can fall toward homes when storms hit. Call 877-787-7363.
