Avoid Getting Shortchanged On ‘Green’ Landscaping Contracts

For commercial property teams and facility managers, trusting landscaping contractors with eco-friendly visions should feel empowering. But too often, teams find themselves tangled in vague promises that sound great—until it’s too late.

How do we protect investments in sustainability upgrades without being misled by eco-marketing? Below is a breakdown of key steps that help prevent costly missteps and ensure your landscaping contractor is delivering actual value—not just buzzwords.

Clarify Environmental Goals at the Outset

Before you speak with any contractor, define what sustainability means for your site. Having clear, prioritized goals upfront empowers you to have better conversations and ask smarter questions. Some examples:

• Reduce water use by 30%
• Attract native pollinators
• Lower mowing and gas-powered maintenance
• Improve soil health through compost and amendments
• Reduce synthetic chemical use

Ask for specifics:

• If they mention reduced irrigation, ask: “How much water are we saving, over what timeframe?”
• If they reference pollinator plants, request a plant list with native species highlighted.
• If soil health is a goal, ask what testing and benchmarks they use.

Concrete answers separate serious professionals from marketing fluff.

Compare Materials and Plant Selection

The word “native” is often misused, so make sure that the plant list doesn’t non-native cultivars bred overseas to mimic native looks without native functions.

Here’s how to stay on top of this:

• Ask for plant labels or delivery receipts
• Cross-reference species with local native plant databases
• Ask where mulch and compost come from—is it certified organic, or just yard waste?
• Request source documentation for all materials: origin, volume, and whether they are locally sourced

Some contractors refuse to provide compost receipts, claiming it came from a “trusted supplier.” They have a habit of mixing woodchips and yard debris—zero compost value. A reputable team will be transparent about materials.

Demand a Transparent Pricing Model

Avoid contracts that hide green materials under a vague “sustainable upgrade” fee. Instead, ask for:

• Per-unit prices: cost per pound of compost, per shrub, per irrigation fixture
• Labor vs. material costs separated
• Brand names of components being used

Honest contractors don’t flinch when you ask for transparency—they welcome it.

Establish Maintenance Responsibilities

The best sustainable designs fall apart without good maintenance. Native plants still need weeding. Drip irrigation still needs flushing. Mulch washes out.

Contracts should define:

• Who maintains what (irrigation, weed control, mulch, seasonal trims)
• How often (monthly, seasonal, on-call)
• How costs are handled if repairs or plant replacements are needed
• If follow-up maintenance is included in the original contract or billed separately

Look for Third-Party Certifications

Some contractors claim green credentials without any formal training. Here’s what to check:

• Is the team certified by a local native plant society, green building council, or xeriscape association?
• Do they follow LEED or SITES standards?
• Have they completed formal sustainability courses?

Certifications don’t guarantee quality, but they do signal that the contractor is invested in standards.

Insist on Written Performance Metrics

You can’t hold a contractor accountable without measurable benchmarks. Ask for written goals tied to the work. For example:

• “Reduce irrigation by 25% within 90 days”
• “Achieve 70% native plant coverage by spring”
• “Increase organic matter from 2% to 5% in one year”

Having things in writing protects you and builds trust.

Plan for Unexpected Site Conditions

Underground roots, compacted soil, or invasive weeds can complicate work. Smart contracts will:

• Acknowledge the possibility of hidden site conditions
• Specify how additional costs are handled
• Require written change orders for scope adjustments

Make sure baseline conditions and site assumptions are documented up front.

Verify Licenses and Insurance

It may seem basic, but licensing and insurance are non-negotiable—especially for:

• Irrigation installation (often requires specific licensing)
• Grading, drainage, or retaining wall work
• Stormwater or rain catchment systems

Ask:

• Are subcontractors insured too?
• Does the insurance cover water damage, flooding, or equipment failure?

Seek Client References with Similar Work

Generic reviews like “great service!” aren’t helpful. Ask for:

• Past projects that reduced irrigation or pesticide use
• Sites where plant survival rate was 80%+ after one year
• Feedback from clients who integrated native landscaping or rain gardens

If a contractor touts big-name projects but can’t refer you to someone with similar goals to yours, that’s a warning sign.

Add Performance-Based Payment Structure

Hold back 10–15% of the contract value until agreed benchmarks are met. Examples:

• Successful irrigation calibration
• Minimum 80% plant survival at 60 days
• Compost visible and documented in planting zones

This structure promotes accountability. One contractor I worked with was far more responsive post-installation because final payment was still pending. Without it, follow-through tends to fall off.

Prioritize Contracts That Embrace Flexibility While Maintaining Accountability

Landscaping is dynamic. Weather, plant availability, and site needs change. Your contract should allow for:

• Adjustments to scope through formal change orders
• Written documentation of timeline shifts and cost impacts
• No verbal agreements—everything in writing

Watch Out for Double-Dipping on Rebates and Incentives

If your city or utility offers rebates for:

• Native plant installation
• Smart irrigation controllers
• Rain barrels or stormwater features

Make sure the contract defines who claims the rebate. Some contractors apply and keep the rebate without lowering your invoice.

Schedule Periodic Project Reviews

Landscape performance reveals itself over time. Plan for:

• 30-day and 90-day reviews
• One seasonal review during peak summer or winter
• A one-year anniversary check-in

At each review:

• Assess plant health and coverage
• Adjust irrigation if needed
• Evaluate mulch condition and soil moisture retention
• Document everything with notes and photos

These check-ins keep contractors engaged and provide data if issues arise. Problems caught early are cheaper to fix.

At National Facility Contractors, we’ve helped facility teams implement steps to avoid greenwashing and lock in measurable landscape performance—often reviewing contract language upfront to ensure green goals turn into real outcomes.

Understand Water-Use and Drainage

“Eco-friendly irrigation” can mean different things depending on execution. Look for:

• Moisture sensors calibrated to your soil type
• Rain shut-off devices
• Drip lines tested for flow and uniform coverage

Don’t accept vague promises—ask for data:

• Gallons per minute per zone
• Precipitation rates
• Schedule logs or app screenshots during hot months

Detect Greenwashing Language

Look beyond buzzwords like “eco-friendly” or “low-impact.” Green contractors demonstrate value through:

• Soil test results showing improvements
• Clear compost ratios (e.g., 30% organic matter)
• Native species lists with scientific names
• Certified mulch or compost
• Specific irrigation settings based on sun/shade or soil zones

If your contractor can’t give specifics, ask: “What exactly makes this sustainable?” The ones who can answer confidently tend to be the ones who deliver.

Conclusion

Green landscaping isn’t just about intention—it’s about execution. The difference between a thriving, low-maintenance landscape and an expensive disappointment lies in the contract details, verification methods, and willingness to hold vendors accountable.

Protect your site, your budget, and your sustainability goals by asking the hard questions up front. Because eco-friendly work should deliver more than good marketing—it should deliver lasting, measurable results.
