Growers who want to stay competitive in 2026 face a clear challenge: produce more while using fewer resources. Sustainable practices are no longer optional. They’re the foundation of a resilient, profitable growing operation.

Introduction

U.S. horticulture generated $18.3 billion in sales in 2024, according to USDA NASS data. That growth brings pressure. Professional growers must balance yield targets, input costs, and rising expectations from buyers, retailers, and regulators, all at the same time.

Responsible growing means producing more with less. It means choosing growing media that performs consistently, managing water with precision, and protecting crops without overloading the environment with chemical inputs.

The top 5 sustainable practices for responsible growing covered here reflect what science-driven growers are doing right now to protect their operations, their supply chains, and the natural resources their businesses depend on.

Why Sustainable Growing Matters for US Horticulture

The business case for sustainability has never been clearer. Consumer demand is shifting, regulatory pressure is rising, and input costs reward efficiency.

Key drivers shaping the market include:

• Consumer expectations: Nearly 49% of Americans report purchasing an environmentally friendly product in the last month, up from 43% in August 2024, according to GlobeScan
• Grower commitment: According to The Packer, 74% of surveyed growers cited sustainability as very or extremely important in business strategy decisions
• Market growth: The sustainable agriculture market reached $16.76 billion in 2025 and is projected to grow to $18.35 billion in 2026 at a 9.5% CAGR
• Water scarcity: Agriculture accounts for roughly 70% of global freshwater use, making efficiency a core operational priority

The 5 Pillars of Sustainable Development in Growing

Responsible growing rests on five interconnected pillars. Each one addresses a specific pressure point that professional growers face today.

The five pillars are:

• Growing media selection: Choosing responsibly sourced substrates that support crop performance and reduce environmental impact
• Water conservation: Applying precision irrigation and moisture-retaining practices across every growth stage
• Waste reduction: Composting organic material and recycling horticultural plastics to divert waste from landfills
• Integrated pest management: Using biological, cultural, and targeted chemical controls to protect crops and reduce pesticide dependency
• Responsible sourcing: Partnering with suppliers whose values and certifications align with long-term sustainability goals

Practice 1: Choose Responsible Growing Media

The growing media a grower selects affects every downstream outcome: water use, nutrient delivery, crop cycle length, and environmental footprint. Science-driven growing media, formulated with ingredients like Canadian sphagnum peat moss, coir, bark, perlite, and dolomite lime, support consistent performance while enabling more efficient resource use.

Sun Gro^® Horticulture, North America’s largest producer of horticultural-grade peat and peat-based growing mixes, develops blends specifically for professional growers. Products like Sunshine^® and Fafard^® mixes are formulated to optimize aeration, water retention, and nutrient availability across a wide range of crops and production systems.

Sustainably Sourced Materials to Prioritize

Responsible growing media starts with responsible ingredients. Canadian sphagnum peat moss harvested from Veriflora^® Responsibly Managed Peatlands certification demonstrates a commitment to good management principles, ecosystem protection, social engagement, and product quality.

Coir, a blend of short fiber and pith left after coconut fiber is extracted from coconut husks, adds bulk and texture to potting mixes and supports aeration and water holding. Bark-based media offer superior drainage and aeration. Black Bear^® Biochar, a sustainable alternative to perlite, enhances cation exchange capacity and water retention while capturing carbon that would otherwise return to the atmosphere.

Evaluating Your Current Growing Media Supply Chain

Growers should audit their current substrate suppliers against clear sustainability criteria. Key questions include whether the supplier holds third-party certifications, whether peat is sourced from responsibly managed peatlands, and whether ingredients are traceable.

Over 40% of global horticulture supply chains are projected to adopt blockchain for transparency and traceability, according to Farmonaut. Growers who demand that same transparency from their growing media suppliers are better positioned to meet retailer and regulatory requirements as they tighten.

Reducing Plastic in Growing Media Packaging

Horticultural plastic waste is a significant challenge. An estimated 500 million plastic plant pots, trays, and flats are produced annually in the United States, generating roughly 350 million pounds of plastic waste, according to Nursery Management.

Growers can reduce their plastic footprint by:

• Choosing suppliers with recycled-content or certified compostable packaging
• Participating in closed-loop programs that recover and recycle used containers
• Tracking diversion rates as a key sustainability KPI for reporting purposes

Practice 2: Conserve Water at Every Growth Stage

Water efficiency is one of the highest-impact areas for professional growers. Agriculture accounts for 70% of global freshwater withdrawals, and that pressure is intensifying. By 2030, global freshwater demand is projected to outpace supply by 40%, according to Farmonaut.

Drip irrigation uses 30 to 50% less water than traditional irrigation methods and is now used on more than 40% of irrigated land for specialty crops in the United States, according to USDA data. Smart irrigation systems using soil moisture sensors achieve an estimated 20 to 40% water savings and are adopted by around 55% of precision farms.

Key water conservation strategies for professional growers include:

• Drip irrigation: Delivers water directly to the root zone, reducing evaporation and weed pressure
• Soil moisture sensors: Trigger irrigation only when plants need it, eliminating fixed-schedule waste
• Rainwater harvesting: Captures and stores precipitation for reuse across the growing operation
• Recirculating systems: Greenhouse recirculating irrigation can reduce water use by up to 50%

Matching Growing Media to Water Efficiency Goals

The substrate a grower chooses directly affects how much water a crop needs. Growing media with optimized water-holding capacity and aeration reduce irrigation frequency without stressing plants.

Metro-Mix^® professional growing mixes, for example, are engineered to balance drainage and moisture retention for specific crop types. Mixes containing Polar Bear^® Wood Fiber support aeration while maintaining adequate moisture levels. Pelemix^® coir components add water-holding capacity that extends time between irrigation cycles. Growers who align their growing media selection with their irrigation strategy can reduce overall water use meaningfully without sacrificing crop quality.

Practice 3: Minimize Waste Through Composting and Recycling

Waste reduction is both an environmental priority and a financial one. Composting reduces greenhouse gas emissions by 34% compared to landfilling or incineration of organic waste, according to World Metrics.

Among horticulture growers, the most commonly reported sustainability practices are recycling (58%), composting (55%), and fertilizer and runoff mitigation (50%), according to Choices Magazine.

Practical steps to minimize waste in a growing operation include:

• Composting plant debris and organic waste to produce inputs that improve soil structure and reduce fertilizer costs
• Joining container recycling programs that divert used plastic pots and trays from landfills
• Tracking landfill diversion rates as a measurable KPI tied to sustainability reporting
• Sourcing growing media in bulk where possible to reduce packaging waste per unit of production

Practice 4: Implement Integrated Pest Management

Integrated Pest Management (IPM) is one of the most evidence-backed sustainable practices available to professional growers. A systematic review of over 200 peer-reviewed studies found that IPM adoption reduces chemical pesticide use by 40 to 70% and enhances crop yields by 10 to 35%, according to Frontiers in Sustainable Food Systems.

The global IPM market reached $26.8 billion in 2025 and is projected to grow to $37.3 billion by 2030 at a CAGR of 6.85%, reflecting how rapidly professional horticulture is moving toward science-based pest control.

The Four Tiers of IPM for Professional Growers

IPM operates across four escalating tiers. Growers apply the least disruptive method first and escalate only when necessary.

The four tiers are:

• Cultural controls: Crop rotation, sanitation, and plant spacing to reduce pest pressure at the source
• Biological controls: Beneficial insects, microbial agents, and natural predators that suppress pest populations
• Mechanical controls: Physical barriers, traps, and removal of infested plant material
• Targeted chemical controls: Low-risk pesticides applied only when pest populations reach economic thresholds

Choosing Growing Media That Supports IPM

Growing media plays a direct role in IPM success. Mixes that are free of harmful pathogens and weed seeds reduce pest pressure before a crop even starts. Products containing RESiLIENCE^®, the silicon advantage, may improve resistance to heavy metal toxicity, salt stress, and wilting. Results will vary by plant type and grower practices.

Well-structured growing media also supports root health, which is the first line of defense against soil-borne pests and disease. Growers who start with a clean, science-driven substrate reduce the conditions that allow pest populations to establish and spread.

Training Your Team on IPM Protocols

IPM only works when the entire team understands and applies it consistently. As of 2024, 78% of U.S. farmers were actively using IPM practices, according to research cited by Eagmark. That adoption rate reflects both regulatory support and grower education.

Effective team training for IPM includes:

• Scouting protocols: Scheduled monitoring of crops for early pest detection
• Threshold guidelines: Clear decision rules for when intervention is warranted
• Record keeping: Documenting pest pressure, interventions, and outcomes to refine the program over time

Practice 5: Source Inputs Responsibly and Support Local Supply Chains

Responsible sourcing extends beyond the growing media bag. It covers every input a grower purchases, from fertilizers and substrates to containers and irrigation equipment.

Shorter supply chains improve reliability and reduce carbon footprints. According to Frontiers in Sustainable Food Systems, local sourcing has shifted from a niche movement to a mainstream expectation, with 59% of Boomers and 45% of Gen Z consumers preferring locally grown produce.

Key responsible sourcing actions for professional growers include:

• Evaluating suppliers on ESG criteria: Look for third-party certifications, published sustainability data, and transparent sourcing practices
• Prioritizing regional suppliers: Shorter supply chains reduce transportation emissions and improve supply reliability
• Requesting ingredient traceability: Know where peat moss, coir, bark, and other growing media components originate
• Supporting certified peatlands: Veriflora^® Responsibly Managed Peatlands certification provides verifiable assurance of responsible extraction practices

How to Measure and Evaluate Your Sustainable Growing Practices

Measurement turns intention into accountability. Over 70% of global agriculture firms now report ESG scores, according to Farmonaut. Growers who track sustainability KPIs are better positioned to meet retailer requirements and demonstrate progress to buyers.

Core KPIs for professional growers to track include:

• Water use efficiency: Total water withdrawal per hectare or per unit of production, tracked against a baseline
• Nutrient use efficiency (NUE): How effectively fertilizers are converted into crop output, reducing runoff risk
• Landfill diversion rate: Percentage of organic and plastic waste diverted through composting and recycling programs
• Pesticide application rate: Volume and frequency of chemical inputs, benchmarked against IPM adoption targets
• Soil organic matter content: A leading indicator of long-term soil health and productivity

Partnering with ESG-Aligned Suppliers and Stakeholders

Growers don’t achieve sustainability goals alone. The suppliers, distributors, and industry partners a grower works with either accelerate or slow progress toward responsible growing.

ESG-rated farms report up to 30% higher resource efficiency compared to non-ESG counterparts, according to Farmonaut. Choosing suppliers who publish sustainability data and hold recognized certifications makes that efficiency gain more accessible.

Criteria for evaluating ESG-aligned suppliers include:

• Published sustainability commitments: Suppliers should have documented goals, not just marketing claims
• Third-party certifications: Look for Veriflora^®, OMRI Listed^®, or equivalent verified credentials
• Transparent ingredient sourcing: Suppliers should be able to explain where every major ingredient originates
• Shared reporting frameworks: Alignment on metrics like GRI or SASB makes supply chain sustainability reporting more consistent

Maximizing Energy Efficiency in Your Growing Operation

Energy costs represent 15 to 25% of total production expenditures in commercial greenhouse operations, according to IMARC Group. Reducing that figure improves margins while lowering the operation’s carbon footprint.

Practical energy efficiency measures for professional growers include:

• LED lighting upgrades: Transitioning from HPS to LED lighting reduces energy consumption for lighting by 10 to 25% in greenhouse systems
• Thermal screens: Energy curtains can reduce greenhouse heating losses by 20 to 75%, according to Greenhouse Grower
• Smart climate control: Model Predictive Control systems have achieved approximately 30% energy savings compared to traditional relay control methods
• Renewable energy integration: Average renewable penetration within commercial greenhouse installations reached 22% in the United States in 2025

Creating a Green Product Line That Resonates with Buyers

Sustainability-marketed products now hold a 25.4% market share in the U.S. consumer packaged goods market and grew at a 10.9% five-year CAGR, nearly five times faster than conventionally marketed goods, according to Capital One Shopping.

Growers who build a green product line can capture that premium. Key steps include:

• Starting with certified inputs: Use growing media with verifiable sustainability credentials, such as peat sourced from Veriflora^® certified peatlands
• Communicating ingredient transparency: Buyers want to know what’s in the growing media and where it comes from
• Reducing packaging impact: Biodegradable or recycled-content containers strengthen green brand positioning
• Documenting outcomes: Track and share measurable results, such as water savings, IPM adoption rates, and waste diversion percentages

Getting Started: Committing to Sustainable Practices Step by Step

Sustainable growing doesn’t require a complete operational overhaul on day one. The most successful growers start with one high-impact practice, measure the results, and build from there.

According to Frontiers in Sustainability, only 18% of growers currently have a formal sustainability plan in place, yet 29% are actively considering one. That gap represents a real competitive opportunity for growers who move first.

Identifying and Committing to Your First Priority

Frequently Asked Questions

What does sustainable growing media cost compared to conventional options in the United States?

Sustainable growing media in the United States is priced competitively with conventional alternatives, particularly when total input efficiency is considered. Growers who use science-driven mixes with optimized water retention often reduce irrigation frequency, lowering overall production costs. Products formulated with Canadian sphagnum peat moss, coir, and bark deliver consistent performance that shortens crop cycles, which improves return on every cubic foot of growing media purchased.

Which U.S. states are leading adoption of sustainable horticulture practices?

Florida leads in several key areas, with 92% of nurseries using IPM in 2021 and 85% of irrigation water recycled across 40,000 nursery acres in 2022, according to Gitnux. California and Arizona show high adoption of drip irrigation for specialty crops, driven by water scarcity regulations. States with strong retailer sustainability requirements, including those in the Northeast, are also accelerating grower adoption of certified sustainable inputs and reporting frameworks.

How does growing media composition affect IPM outcomes?

Growing media that is free of weed seeds and soil-borne pathogens reduces the pest and disease pressure a crop faces from day one. Mixes with balanced aeration and moisture retention support strong root development, which is a plant’s primary defense against stress and pest establishment. Products containing RESiLIENCE^® may improve resistance to salt stress and heavy metal toxicity, though results will vary by plant type and grower practices.

How does sustainable growing compare to conventional growing for crop yield?

A 2025 multi-country study found that regenerative farmers achieved just 1% lower yields compared to conventional production while using 62% less synthetic nitrogen fertilizer and 76% less pesticides per hectare, according to Nature. IPM adoption across 85 projects in 24 countries produced a mean yield increase of 40.9% combined with a 30.7% decline in pesticide use compared to baseline, according to Frontiers in Sustainable Food Systems.

How long does it take to implement a sustainable growing program?
