Tree Trimming in Brentwood, CA

Tree Regulations and Permits

Do you need a permit?

In Brentwood, most routine pruning and maintenance of trees on private property doesn’t require a permit. However, removal, relocation, or substantial alterations to certain trees can trigger permit requirements. The City regulates trees in public rights-of-way, on public property, and trees designated as protected under the Tree Protection Ordinance. Always verify before work; obtaining a permit helps avoid fines and ensures proper replanting or mitigation if needed.

Which trees are protected?

• Large or mature trees, certain species (often including oaks), and trees located in the public right-of-way may be protected.
• Protected status can apply regardless of property ownership; curb-adjacent trees can fall under City oversight.
• Exact protections, species lists, and size thresholds are defined in Brentwood’s Municipal Code and related administration guidelines.

What requires a permit?

• Removal of a protected tree.
• Work that affects the root zone, canopy, or limb structure of a protected tree.
• Pruning that goes beyond ordinary maintenance or involves proximity to utilities, sidewalks, or structures.
• Removal or significant pruning within the public right-of-way or on public property.

How to apply (step-by-step)

1) Identify ownership and location: private lot vs. public right-of-way; verify whether curbside trees are under City oversight.

2) Gather information: tree species, approximate diameter (DBH) if known, photos, and a clear description of the proposed work.

3) Submit the permit: use the City of Brentwood online permit system or contact Planning/Development Services; include any required fees.

4) City review: an arborist may assess health, risk, and mitigation needs; a preservation plan or replanting requirements may be imposed.

5) Permit outcome: receive approval with conditions or notes; schedule inspections as work proceeds or after completion.

Emergency or hazardous tree work

• If a tree poses an immediate risk to people or property, you may perform emergency work and apply for a retroactive permit afterward.
• Document the hazard with photos and notify the City as soon as practical to stay in compliance.

Warnings and local risks

• Fines or mandated mitigation for unpermitted removal or alteration.
• Risk of damaging underground utilities; always call 811 before digging or pruning near utilities.
• Insurance or lender requirements may apply; noncompliance can affect coverage or transactions.

Common Tree Species in Brentwood

Brentwood sits in a hot, inland valley climate with long, dry summers and mild, wetter winters. Soils are often clayey or compacted, which can stress roots and slow drainage. The urban landscape here faces drought pressures, heatwaves, and seasonal winds from the Diablo Range, plus nearby almond and vineyard activity that can influence soil moisture and root competition. Native oaks anchor many yards, while ornamentals like olives, pistache, and pines line streets. Understanding how Brentwood’s microclimates—sun-exposed lanes, fenced courtyards, shade pockets under eaves, and hillside soils—affect water needs, pruning timing, and pest risks helps you keep trees healthy and safe year-round.

• In our heat-prone, drought-aware environment, choose species with good drought tolerance and deep roots.
• Watch for turf and soil compaction near sidewalks and foundations; mulching helps conserve moisture and protect roots.
• Fire safety and wind exposure matter on hillside and open-lot sites; avoid placing tall trees where winter storms could cause limbs to fall on structures or lines.
• For native oaks and some protected species, check Brentwood’s permit requirements before removal or major pruning.

Coast Live Oak

• Local prevalence and challenges in Brentwood: A native-referenced favorite on hillside properties and larger lots. They’re long-lived, but can suffer from drought stress, root competition, and diseases such as sudden oak death in some areas. Large canopies can pose wind-loading risks in winter storms.
• Pruning and care tailored to Brentwood:
• Prune only as needed, preferably late winter to early spring, to preserve water balance and reduce disease exposure.
• Remove crossing branches and weak crotches to improve structure; avoid heavy crown reductions.
• Water deeply but infrequently during dry spells; mulch to protect shallow roots.
• When removal or major work is needed and permits: Remove only if dead, structurally compromised, or severely diseased; native oaks can require a permit in some jurisdictions—check Brentwood Planning/Building or Contra Costa County for requirements.
• Resources: UC IPM (oak pests and diseases) and local extension guidance; USDA hardiness references for climate suitability.

Valley Oak

• Local prevalence and challenges: A large, stately native that often anchors spacious yards and foothill properties. Susceptible to drought stress, limb splitting in older wood, and root crowding near structures.
• Pruning and care:
• Best to prune during dormancy with light maintenance rather than heavy shaping; avoid flush cuts.
• Provide deep irrigation during extended droughts and mulch to protect roots.
• Monitor for bark cracks or dieback that may signal disease or borers.
• When removal or major work: Consider removal if the tree poses a significant failure risk or root invasion damages foundations; permits may be required for protected native trees.
• Resources: UC IPM oak resources; local arborist guidance for protected species.

Blue Oak

• Local prevalence and challenges: Common on open lawns and over-drought-prone soils; appreciates sun but can be sensitive to extended drought and soil compaction.
• Pruning and care:
• Light annual pruning to maintain taper; avoid heavy crown thinning.
• Water deeply during drought and avoid frequent shallow irrigation.
• Mulch under the dripline and keep mower clearance to protect roots.
• When removal or major work: Remove only if structurally unsound or located where root conflicts threaten structures; verify permit needs with the city.

Helpful resources include UC IPM (ipm.ucanr.edu) and the USDA Plant Hardiness Zone map (planthardiness.ars.usda.gov).

Signs Your Tree Needs Attention in Brentwood

Brentwood homeowners contend with hot, dry summers and wet, sometimes stormy winters. Our clay-heavy soils often stay compacted and slow to drain, which can weaken roots and magnify stress during drought or after heavy rains. Local winds from the Diablo Range and seasonal gusts canTest push weak limbs loose if a tree is already compromised. Because climate patterns here are shifting toward longer dry spells and sharper deluges, the warning signs you see may escalate quickly from minor cues to real hazards. Start with universal red flags, then interpret them through Brentwood’s unique conditions.

General Red Flags for Any Tree

• Dead, dying, or visibly discolored branches, especially in the lower canopy or on the side facing prevailing winds.
• Cracks or splits in the trunk, or a trunk that appears to lean without normal trunk movement.
• Roots that are exposed, girdled, or soil that has heaved near the base.
• Fungal growth on the trunk, roots, or at the soil line (toadstools, bracket fungi, or mushrooms at the base can indicate internal decay).
• Oozing sap, resin, or cankers that don’t close over with time.
• Cavities, hollow sounds when tapping branches, or a trunk that feels soft when pressed.
• Structural damage near structures, sidewalks, or fences, including sudden subsidence or lifted surfaces.
• Persistent dieback or thinning foliage in the canopy, even after a reasonable watering cycle.

How this looks in Brentwood:

• After wet winters, you may notice soft, crumbly wood in the base or a quick spread of shallow-root decay—this raises the chance of sudden limb failure during spring growth or a storm.
• In late summer droughts, previously healthy branches may begin to die back from the tips inward, signaling deeper stress and potential weak points.

Species-Specific Symptoms Common in Brentwood

• Coast Live Oak and Valley Oak
• Sudden limb dieback, especially on older trees.
• Basal cankers or cracking bark; thinning crowns with sparse leafing.
• Soil-edged girdling or rapid root damage after heavy rains can predispose to trunk instability.
• Eucalyptus and other tall ornamentals
• Large limbs with exposed, peeling bark or tight, horizontal cracks in the trunk.
• Heavy crowns that have grown too quickly for the root zone, making them prone to limb drop in wind or rain.
• Noticeable bark shedding and thinning internodes that precede branch failure.
• Citrus and other small fruiting trees (common in Brentwood yards)
• Dieback in one sector of the canopy, limb shedding, or small cracks in bark.
• Cankers at the graft union or at limb junctions; uneven fruiting and leaf scorch during heat waves.
• Palms and drought-tolerant ornamentals
• Fronds browning from the base up, trunk splits, or sudden crown collapse after storms.

Storm and Wind Damage Risks Here

• Saturated soils after winter storms heighten the risk of uprooting and leanings in trees with shallow or restricted root zones.
• Diablo Range winds can accelerate limb failures in trees with weak crotches, wavy grain, or previous pruning cuts that aren’t fully healed.
• After a heavy event, look for:
• Dangling or partially detached limbs over driveways, sidewalks, and roofs.
• Leaning trunks or trees that topple when gusts hit peak levels.
• Cracked root plates or exposed root zones along driveways or lawns.
• Immediate actions (steps you can take now, without attempting risky pruning):

1) Keep people and pets away from the tree’s base and any overhanging branches.

2) Do not attempt to remove or prune large limbs yourself; risk of sudden failure is high.

3) Contact a certified arborist to assess risk and outline a plan for pruning, bracing, cabling, or removal as needed.

4) If you’re renting or living near structures, consider temporary barriers or temporary relocation of vehicles to avoid damage from a possible limb drop.

Preventive notes for Brentwood properties:

• Regular, lighter maintenance pruning can reduce wind catch and stress on the main scaffold limbs, provided done by a qualified arborist who avoids cutting into the tree’s live tissue too aggressively.
• Soil management matters: avoid soil compaction around the root zone, and ensure deep, infrequent irrigation to support deep root growth during drought periods.
• After storms, schedule an inspection if you notice cracking, new tilting, or any heavy limb that was previously sound.

Pest and Disease Signs to Watch For Locally

• Thinning canopy with uneven leaf coloration, especially on sunny slopes or exposed yards, can signal drought-stress combined with pest pressure.
• Bark patterns showing tiny holes, frass (sawdust-like material), or frayed cambium around wounds may indicate borers or wood-boring insects that exploit stressed trees.
• Fungal mats, soft white rot near the base, or shelf-like bracket fungi at or above soil level are strong signs of internal decay that compromise structural integrity.
• Gum exudation or oozing from cracks may signal infection or a pest vector that requires treatment.
• Common Brentwood scenarios:
• Drought-stressed oaks and fruit trees becoming susceptible to borers and fungal decay.
• Irrigated landscapes that stay too wet for too long, setting the stage for root rot and crown cankering.
• Quick actions:

1) Do not attempt to treat severe infestations yourself; early, professional diagnosis is crucial.

2) Monitor for rapid changes in foliage color or crown density, which can indicate pest or disease progression.

3) Consult UC IPM resources for California-specific tree pests and diseases to understand treatment options and a pest management plan (examples: UC IPM’s Tree Pests and Diseases guides and pest notes at ipm.ucanr.edu).

Best Time of Year for Tree Work in Brentwood

Brentwood’s climate is a classic inland Mediterranean pattern: hot, dry summers with ample sunshine and cooler, wetter winters. Average winter rains arrive from November through February, while summer moisture is scarce and soils can dry quickly. Frost is possible on the coldest mornings, but extended freezes are rare. Winds can pick up in fall and during storm cycles, and during drought years the soil and root zones can become stressed. This mix means timing pruning, trimming, and removal requires balancing winter dormancy benefits with soil moisture, wind risk, and fire-season awareness. In practice, many jobs are best done when the ground is dry, trees are dormant or just waking, and the weather window won’t stress freshly cut tissue or expose fresh cuts to heavy rain, sun, or pests.

Years of Brentwood weather also mean planning around peak seasons. Wet winters slow access, muddy soils complicate equipment use, and storm events can lead to storm damage that demands urgent attention. Dry summers, by contrast, reduce disease pressure but increase stress on trees after pruning if extended heat follows a cut. Coastal air influences are present but muted inland, so local microclimates (urban heat islands, exposed hillside yards, or shade pockets) can shift the ideal window a few days. Plan ahead, book trained arborists early for peak pruning periods, and tailor timing to the specific species in your yard.

General Guidelines for Most Trees

• Prune primarily during dormancy (late fall through winter) when leaves are off and growth is minimal. Benefits include reduced sap loss, cleaner cuts, and slower new growth.
• Schedule work for dry soil periods to protect root zones and minimize soil compaction and equipment tracking.
• For hazard removal or storm damage, address the problem promptly, then schedule cosmetic pruning later if needed.
• Use clean, sharp tools and disinfect between cuts to limit disease spread. Consider wound care practices recommended by ISA and UC IPM guidelines.

Optimal Seasons for Pruning Common Local Species

• Maples (Acer spp): prune in winter dormancy to minimize sap bleeding; if a quick shape is needed, light pruning can occur after leaves unfurl, but monitor sap flow to avoid excessive bleeding.
• Oaks (Quercus spp): avoid high-prain pruning during peak beetle/wasp activity; generally best in late winter. Be aware of local oak-wilt risk and any county permits or seasonal restrictions.
• Stone fruit and other fruit trees: prune in late winter to early spring when trees are fully dormant but before buds swell; remove diseased or damaged wood promptly after harvest to reduce spread.
• Olive trees: late winter to early spring pruning after fruit harvest is common; avoid heavy pruning in extreme heat or drought weeks.
• Eucalyptus and other ornamentals: late winter to early spring generally works for structural work; avoid aggressive pruning during heat spikes or drought stress.
• Sunsensitive, thin-barked species (birch, young maples): minimize exposed cuts in late winter to early spring to prevent sunscald as new tissue forms.

When to Schedule Tree Removal

• Plan removals in late fall through winter when soils are more settled and trees are dormant, reducing storm risk and making access easier.
• For emergency removals after storms or when limbs pose immediate danger, do not delay—safety first, then arrange cleanup and pruning after.

Seasons to Avoid and Why

• Late spring through early summer: higher sap flow on maples and other species can lead to excessive bleeding, attracting pests and delaying wound closure.
• Peak heat weeks in mid/late summer: stress from pruning increases risk of sunscald on thin-barked trees and can dry freshly cut tissue too quickly.
• Peak drought periods: avoid heavy pruning that stresses an already water-limited tree; coordinate irrigation after cuts.
• Wet winter storms: working in saturated soils increases compaction risk and can spread disease; aim for dry windows between storms.

Emergency Work and Storm Season Considerations

• Severe storms require rapid assessment and removal of hazardous limbs. Afterward, schedule shaping or thinning when conditions are safer and trees have time to recover.
• If you’re managing a firewise property or near dry brush, plan pruning and removal with fire-season safety in mind (clearance around structures, reduce ladder fuels, and avoid creating new fuel ladders with fresh cuts).

Practical tips

• Book pros early for peak pruning windows (late winter for most species; adjusted by species timing and weather).
• Watch for sap flow in maples and other sapsucker-prone trees; if you see heavy bleeding, adjust timing.
• Monitor for pest and disease entry points tied to cut timing; use appropriate pruning cuts and sanitation.
• For disease risks and pruning best practices, refer to ISA pruning guidelines and UC IPM resources as trusted local references.

Average Costs for Tree Services in Brentwood

Brentwood’s tree-work costs are shaped by local labor rates in East Contra Costa, access challenges on large suburban lots and hillside properties, disposal and recycling fees, seasonal demand, and permit requirements. Tall conifers and dense backyard vegetation add complexity, which can push prices higher than national averages. In Brentwood, many homes sit on spacious lots with mature evergreens, so pruning and removal often involve longer climb times, more debris, and stricter cleanup expectations.

Weather patterns and local regulations also play a role. Harsh winter storms or heat waves can spike demand and surge emergency rates, while permit processes in some neighborhoods add an upfront cost to remove or heavily prune protected trees. By understanding these local dynamics—plus disposal costs at nearby facilities and fuel prices—you’ll get pricing that reflects Brentwood’s unique landscape.

Typical Cost Ranges for Tree Trimming and Pruning

• Small pruning or shaping (6–10 ft): $150–$350
• Medium pruning (10–20 ft): $250–$700
• Large pruning (20–40 ft): $500–$1,800
• Very tall or complex pruning (40+ ft, multi-trunk, near structures): $1,500–$3,000+, depending on access and crew time

Notes:

• Prices vary with tree species, branch density, and required climber or bucket-truck time.
• If multiple trees are pruned in one visit, crews may offer a volume discount, but ensure the scope includes cleanup and disposal.

Tree Removal Costs by Size and Complexity

• Small tree removal (<30 ft): $400–$1,500
• Medium removal (30–60 ft): $1,500–$3,500
• Large removal (>60 ft): $3,000–$8,000
• Highly complex or dangerous removal (tight spaces, near structures, steep slopes): often $5,000–$15,000+, with the exact price driven by access, equipment, and safety requirements

Notes:

• In Brentwood, hillside properties and lots with limited access can push crew time higher.
• If the tree is leaning, electrified lines, or has significant rot, expect higher quotes and a more involved job plan.

Stump Grinding and Removal

• Small stump (up to 8–12 in diameter): $100–$250
• Medium stump (12–18 in): $250–$500
• Large stump (18–24 in or bigger): $350–$700
• Per-inch pricing (alternative method): about $2–$3 per inch of diameter

Add-ons:

• Some crews charge extra for grinding multiple stumps, deep grinding below grade, or removing root systems.
• If you want the sawdust and chips hauled away, confirm disposal charges upfront.

Additional Fees and Add-Ons

• Permits and arborist plans: $50–$200 typical for a basic removal permit; costs vary by neighborhood and permit type.
• Debris disposal and hauling: included in some quotes; otherwise $60–$150 per load or per trailer.
• Access fees: gated communities, steep driveways, or remote yards: $50–$200
• Storm/emergency surcharge: 1.5× to 2× normal rates during and after weather events
• Cleanup and hauling of debris: ensure the quote specifies final cleanup; some bids leave piles for you to dispose of

Local context:

• Brentwood’s disposal costs can depend on nearby recycling facilities and landfill fees, which influence overall pricing for debris removal and chipping.
• Weather-driven spikes are common; plan for some fluctuation between typical shoulder seasons and storm seasons.

Ways to Save Money Locally

• Get 3–4 written quotes to compare scope, price, and inclusions.
• Ask for inclusive bids that cover pruning/removal, clean-up, and wood/chips disposal; avoid bids that bill cleanup as a separate line item.
• Schedule off-peak: late winter to early spring often yields lower rates than peak summer demand.
• Bundle projects: if you have several trees to prune or remove, arrange for a single crew to handle them to secure a discount.
• Confirm scope and access: ensure the bid clarifies equipment used (bucket truck vs. climber) and whether there’s any extra charge for steep or gated access.
• Check insurance and credentials: insist on proof of insurance and licensing; low bids without coverage are a red flag and risk liability for damage or injury.
• Red flags in bids: unusually low prices that exclude cleanup, refuse a written scope, cannot provide references, or lack proof of insurance.

Key cost factors specific to Brentwood

• Access on hillsides and long driveways increases crew time and fuel use.
• Disposal costs and mulch/chips value vary by local facilities and demand.
• Weather-driven demand spikes can briefly push prices higher after storms.
• Permit requirements in certain neighborhoods add upfront costs but may avoid violations or fines later.

Helpful resources for reference

• ISA Tree Cost Guides for typical pruning, removal, and consults
• California Department of Consumer Affairs for contractor and licensing guidance
• Local BBB reviews and contractor ratings to vet firms and prevent scams

By understanding these Brentwood-specific dynamics, you can navigate quotes with realistic expectations and avoid common pricing pitfalls.

Aftercare and Long-Term Tree Maintenance in Brentwood

Brentwood’s Mediterranean climate means trees face both extremes: dry, hot summers and moist winters. Proper aftercare matters here because pruning wounds can heal slowly in long, wet winters, while drought stress during hot summers can weaken a tree’s defenses. Soil in Brentwood ranges from heavy clay pockets that shed water slowly to sandy, well-drained patches that dry out quickly. Sloped lots and foundational constraints also affect rooting and water movement. Tailoring aftercare to these local conditions helps trees recover faster, resist pests and disease, and keep their structural integrity for years to come.

Immediate Post-Trimming or Removal Care

• Leave wounds to callus naturally. Do not paint, seal, or otherwise dress pruning cuts with petroleum-based or paint-like products unless a certified arborist recommends it for a specific issue. These coatings can trap moisture and create a microclimate that invites rot.
• Inspect for bark tearing or exposed cambium. If you see torn bark or exposed tissue, monitor for sudden sap flow or oozing after rain. Contact an arborist if there are deep cracks or signs of decay.
• Protect large pruning cuts from sunscald in winter and from sun-scorch in full summer sun. Temporary shading (e.g., a light burlap shield for a day or two) can help on tender wounds, but remove promptly to prevent heat buildup.

Watering Guidelines for Local Conditions

• Deep, infrequent watering is usually best in Brentwood. For clay soils, water less often but longer to encourage deep root growth; for sandy soils, water a bit more frequently but still deeply.
• Use the “soak and drain” method: slowly apply water until it slightly pools, then let the soil drain and repeat until water has penetrated to the root zone.
• Adjust during heat waves, drought restrictions, and rainy winters. In hot summers, trees may need 1–2 inches of water per week (including rainfall). In winter, reduce or pause irrigation unless the soil remains very dry.
• Avoid standing water around trunks. Poor drainage invites root rot and fungal issues, especially on clay soils.

Mulching and Soil Health

• Apply 2–4 inches of mulch in a wide ring from the canopy dripline inward, keeping mulch several inches away from trunks to prevent moisture buildup against bark.
• Use chipped yard debris, shredded bark, or composted mulch sourced locally when possible. Brentwood municipal programs or local landscape suppliers often offer screened mulch.
• Keep mulch on a slope from washing away with rains or irrigation; for terraced or hillside yards, create defined mulch beds that stay in place.

Monitoring for Stress, Pests, and Disease

• Annual checks are worth the effort: look for leaf scorch, premature leaf drop, yellowing, or thinning canopy during or after heat spikes.
• Common Brentwood issues include scale on ornamentals, aphids on fruit trees, and fungi on stressed roots. Early detection makes treatment easier and less risky.
• Take photos and note timing of symptoms. If pests or disease appear, consult an ISA-certified arborist or UC IPM resources for diagnosis and treatment options.

Long-Term Pruning and Maintenance Schedule

• Structural pruning for young trees: every 2–3 years to establish a strong center or preferred branch structure. Avoid heavy cuts that remove too much leaf area in a single year.
• Maintenance pruning for established trees: once a year or every other year, targeting diseased wood, crossing branches, and those that rub or have poor angles.
• Cable and bracing: may be considered for storm-prone trees with weak unions. Only a certified arborist should install and periodically inspect supports to avoid girdling or trunk damage.
• Plan for slope and foundation proximity: ensure root growth is directed away from structures and irrigation lines.

Stump Management and Site Restoration

• Decide between stump grinding, removal, or leaving a stump to decompose naturally. Grinding is quick but creates a nearby dust and noise footprint; natural decay takes longer.
• After stump removal, restore the site with a mix of compatible groundcovers or native grasses suitable for Brentwood soils to prevent erosion on slopes.
• Reuse the space: if you’re restoring a sunny bed, consider drought-tolerant evergreens or native shrubs that fit your yard’s microclimate.

Replanting Recommendations for Brentwood

• Choose drought-tolerant, climate-appropriate species. Native oaks (where appropriate and permitted), California lilac (Ceanothus), manzanita, and certain drought-tolerant citrus and fruit trees perform well with proper irrigation.
• Avoid water-hungry species in small yards with limited soil volume. Consider columnar or smaller-stature trees to reduce trimming needs while maintaining shade.
• Spacing matters on sloped terrain. Provide adequate room for mature canopy spread and root systems, and avoid planting too close to sidewalks, driveways, or foundations.
• Soil testing can guide amendments. A simple soil test helps determine pH and nutrient levels to tailor compost, gypsum (for clay soils), or lime as needed. Local soil testing labs or the UC Cooperative Extension office can guide you.

Wounding myths are common, but a calm, patient approach wins in Brentwood. Fertilize only when a soil test shows a deficiency, and avoid routine, heavy feeding. For storm-prone yards, selective cabling or bracing—installed and inspected by a certified professional—can provide protection without harming the tree’s growth. Annual inspections by a licensed arborist or a certified tree care professional help maintain safety and vitality.

Wrapping Up: Keeping Your Trees Healthy and Safe in Brentwood

In Brentwood, our warm summers, dry spells, and seasonal winds mean thoughtful tree care isn’t just about aesthetics—it’s about safety, long-term health, and a thriving landscape. When homeowners stay informed and proactive, they help trees weather stress, reduce hazards, and provide shade, habitat, and beauty for years to come.

Balancing safety with preservation is central to Brentwood’s tree care. This means navigating local regulations with care, planning for drought and shifting climate patterns, and choosing species and pruning practices that preserve our evergreen character. By staying engaged, consulting qualified professionals, and considering the community impact of every cut or removal, you help create a resilient canopy that protects homes, supports wildlife, and enhances the neighborhood’s identity.

Final reminders for a healthier, safer canopy:

• Regular inspections: Have a certified arborist assess your trees every 1–3 years (or more often for high-risk specimens or rapidly growing trees) to catch structural issues, decay, or pest problems early.
• Work with certified professionals: Hire ISA-certified arborists for pruning, cabling, or removals. Proper techniques protect long-term health and reduce the risk of failure.
• Plan for seasonal risks: Anticipate heat waves, drought, and windy periods. Water deeply during dry spells, apply mulch to conserve moisture, and avoid unnecessary pruning during peak heat or high-wind days.
• Contribute to the canopy: Plant climate-appropriate species, support local tree-planting efforts, and protect root zones from damage. A diverse, well-cared-for canopy benefits everyone.
