Tree Planting Service Cost in Seattle

Professional tree planting service in the Seattle Metro Area typically runs $400-$1,200 per tree installed for standard residential planting. The price includes the tree, installation labor, mulch ring, initial watering setup, and a one-year establishment guarantee for properly sited species. Smaller caliper trees (1 to 1.5 inches) sit at the lower end of the range; larger caliper trees (2-3 inches) and specimen specimens sit higher. Evergreen privacy plantings (arborvitae, Western red cedar) typically run $200-$500 per tree installed when planted in quantity. Larger specimen trees — mature Japanese maples, Persian ironwood specimens, structural shade trees — can run $1,500-$4,000+ per tree depending on species and size. Bulk plantings for screens or orchards typically price lower per tree because crew efficiency scales with quantity.

A standard tree planting service typically includes:

• The tree itself — sourced from regional nurseries, root ball quality verified
• Site assessment for placement — confirming the spot suits the species’s mature size, sun and shade conditions, and proximity to structures
• Excavation at appropriate width and depth — hole prepared to expose root flare at grade
• Installation per arboricultural standards — root ball positioned, native soil backfill, root flare visible
• Mulch ring application — 2-3 inches deep, 3-5 feet diameter, kept off the trunk
• Initial watering — thorough first soak after planting
• Staking when warranted — most residential plantings under 2-inch caliper don’t need stakes; staking added when site conditions require it
• One-year establishment guarantee — if the tree doesn’t establish under proper care, replacement is included

What’s typically not included in standard pricing:

• Stump removal for trees being replaced
• Soil amendment beyond standard backfill
• Irrigation system installation
• Long-term watering service after the first soak

The full planting protocol is documented in the tree planting timing guide.

Six factors shape tree planting pricing:

Caliper size at install. The most predictable variable. A 1-inch caliper tree costs substantially less than a 2-inch caliper specimen of the same species. Larger specimens require more material, more equipment, and more labor — and the bigger trees from nurseries are not proportionally larger in cost; they’re often exponentially more expensive.

Species specification. Common landscape species (red maple, vine maple, dogwood, arborvitae) cost less than premium specimens (Persian ironwood, mature Japanese maple cultivars, rare conifers). Some Japanese maple cultivars at specimen size run $1,500-$4,000+ per tree alone.

Site access. Truck-accessible drop points cost less than properties requiring hand-carry of the tree and root ball. Larger trees become impossible to hand-install at some caliper threshold and require equipment access.

Existing site preparation. A planting hole in lawn or open bed costs less than a hole requiring tree-root navigation, rock removal, or significant soil amendment.

Stake and protection requirements. Properties in deer pressure zones (east of I-405, Sammamish plateau, Issaquah Highlands) typically need trunk protection during the establishment period. The protective fencing or cages add modest cost.

Quantity discounts. Single tree installations cost more per tree than 10-tree projects. Bulk privacy screen plantings of 15-30 arborvitae or similar trees can run substantially lower per tree because crew mobilization and equipment efficiency scale.

Tree planting is typically the highest per-unit planting cost across residential landscape work:

• Bulb planting — under $5 per bulb installed in bulk, $10-$25 per bulb for small specialty plantings
• Perennial plant installation — $25-$75 per plant installed depending on size
• Shrub installation — $75-$300 per shrub installed depending on species and size
• Tree planting — $400-$1,200 per tree at standard sizes, higher for specimens

The per-unit cost difference reflects the substantial labor, equipment, and material investment in tree installation versus smaller plant categories. Trees also carry longer-term value — properly sited trees increase property value and provide decades of structural landscape benefit.

The evergreen tree fall planting guide covers privacy screen plantings where per-tree cost scales differently than single specimen work.

Tree planting is one of the categories where DIY is genuinely viable for many homeowners, with real trade-offs:

DIY makes sense when:

• The tree is 1 to 1.5 inch caliper (manageable for two people)
• The species is well-matched to the site (matching matters more than perfect installation)
• The site has good access (no hand-carry required)
• You’re committed to the year-one watering schedule (the most common reason DIY trees fail)

Professional installation makes sense when:

• The tree is 2-inch caliper or larger (weight and equipment requirements exceed safe DIY scope)
• Multiple trees in one project (3+ trees benefits substantially from crew efficiency)
• The species choice affects long-term success (horticultural lens matters)
• Site preparation is non-trivial (root navigation, drainage, slope)

The DIY cost saving on a single 1.5-inch caliper tree typically runs $200-$400 versus professional installation. On bulk plantings or larger specimens, the cost difference narrows or reverses because professional efficiency scales while DIY does not.

The most common reason DIY trees fail isn’t installation technique — it’s underwatering during year one. Trees need deep weekly watering through the first growing season; many homeowners water too shallowly or stop too early. The professional guarantee typically covers establishment specifically because the watering discipline matters substantially.
