How big is the lawn & garden industry, really?

Reputable sources put the same industry at $7 billion, $52 billion, $167 billion, $186 billion, and $330 billion. They are all correct. They are also all measuring different things. A definitions guide.

Anyone who has spent ten minutes researching the gardening industry has run into the same disorienting problem. One report says the US lawn & garden category is a $7 billion business. Another says it's $52 billion. A third puts it at $167 billion. A fourth pegs the global landscaping services market at $330 billion. These are not approximations of each other. The smallest figure is roughly two percent of the largest. They cannot all be the same number with rounding error. Yet they are all, in their own terms, correct.

What's actually happening is that "the lawn and garden industry" is not one industry. It's a stack of overlapping markets, ranging from the narrow (just consumables, fertilizer, soil, seeds) through the medium (those plus tools, equipment, and live plants), through the broad (everything consumers spend on lawn and garden), all the way up to the very broad (every dollar paid to anyone who builds, maintains, or services outdoor spaces, including commercial work). Each layer of the stack is measured by different researchers, with different methodologies, and there's no agreed-upon vocabulary that distinguishes them clearly. The result is a body of public reporting where reasonable people can quote "the size of the industry" and produce numbers that differ by an order of magnitude, without anyone being wrong.

This essay walks through what each layer actually contains, what figures the major researchers attach to each layer, and which number you should use for which kind of conversation. By the end, the disorientation should be replaced with something more useful: a vocabulary for talking about the industry that doesn't fall apart on closer inspection.

Five layers, five very different numbers

It helps to lay out the full vertical stack before drilling into any single layer. Here are the five concentric ways the industry is reported, ordered from narrowest to broadest, with representative figures from publicly available 2024–2025 research:

What follows is a walkthrough of each layer, what's inside it, who measures it, where the boundaries actually fall, and what kind of question each layer is the right answer to.

Layer 1: Consumables only: roughly $7B in the US

The narrowest defensible measure of "the gardening industry" is consumables. These are products that get used up and replaced on a seasonal cycle: fertilizers, pesticides, herbicides, soil and soil amendments, seeds, mulch, growing media. Precedence Research valued the US lawn and garden consumables market at $6.97 billion in 2024, and projected it to reach $12.75 billion by 2034 at a 6.23% CAGR.

This figure has the virtue of being clean, it counts product categories that don't overlap with anything else and are all sold through the same retail channels. It also has the limitation of excluding most of what people think of as "gardening", the plants, the tools, the equipment, the labor, and so it dramatically understates how much economic activity sits in the category. If you've ever seen "the gardening industry is worth $7 billion" and thought it sounded too small, this is why. It is too small. It's measuring one slice.

Layer 2: Total household L&G spending: $52B–$76B

Add live plants, ornamentals, hand tools, basic gardening equipment, and outdoor décor to consumables, and you arrive at the layer that the National Gardening Association measures every year through its consumer surveys. Per the NGA's 2024 edition, US households spent $52.3 billion across 122.3 million participating households on lawn and garden activities. Per the 2024 edition coverage in Garden Center Magazine, the 2023 figure rose to approximately $75.9 billion with average household spend around $671, a meaningful jump driven primarily by lawn care, hardscaping, and landscaping increases.

This is the layer most often quoted in mainstream business coverage when journalists describe "the US gardening industry," because it's the layer that maps cleanest to the average person's mental image of the category, a household actively gardening as a hobby, summed across the full population. It excludes professional services performed by paid landscapers (Layer 4) but includes everything households self-report spending on the category, including pay-someone-else lawn care.

If someone asks you "how much do Americans spend on gardening?" and they mean it as a consumer-spending question, this is the right answer. The range, $52B to $76B, reflects year-over-year variation and the survey's expanding scope rather than methodological uncertainty.

Layer 3: Lawn & garden retail (channel view): $50B+

The third layer measures the retail channel rather than the consumer side. Add up power equipment (mowers, trimmers, blowers, tillers), hardscape supplies (pavers, edging, retaining-wall blocks), outdoor furniture, irrigation hardware (drip systems, sprinklers, controllers), smart gardening hardware (grow lights, soil sensors, hydroponic units), and the back-end SKUs that pad out the average Home Depot garden center. The result is roughly $50 billion in annual retail flow.

Bloomscape's investor materials cited a $50 billion-plus retail lawn and garden segment in their 2020 Series B announcement. Per the 2021 Garden Media Trends Report (cited via secondary aggregators), American gardeners spent a record $47.8 billion in lawn and garden retail sales that year. Trade aggregates have produced similar figures in subsequent years. This is the layer that captures the full retail surface, not just what households consciously think of as "gardening," but everything that sits in the lawn-and-garden aisle of a major retailer.

Layer 2 (household activity spending) and Layer 3 (retail channel sales) overlap heavily, but they're not the same number. Households also pay landscapers and buy through non-retail channels; retailers also sell to commercial buyers and out of the household-gardening category. The numbers being similar in size is coincidence, not identity.

This layer is the one most useful for retailers, brands, and supply-chain operators thinking about total addressable market for product. It's also the most volatile across reports, because researchers disagree heavily on whether power equipment, outdoor furniture, and hardscape "belong" inside lawn and garden or in adjacent categories like home improvement and outdoor recreation.

Layer 4: Landscaping services (US): $159B–$188B

Now stop counting things and start counting labor. This is where the headline numbers get big, and where most casual readers get confused, because the words "landscaping services" sound narrower than "the gardening industry" but actually represent a much larger pool of money.

Landscaping services count every dollar paid to professional firms that design, build, maintain, and enhance outdoor spaces, across residential, commercial, municipal, and institutional clients. This includes lawn mowing, plant care, hard- and soft-scape installation, tree services, irrigation system care, snow removal, and seasonal maintenance. It includes both ongoing maintenance contracts (which generate predictable recurring revenue) and one-off project work (design-build, large installations).

The figures from major researchers have converged in a fairly tight range:

• IBISWorld (via NALP): $188.8 billion in 2025, with the industry employing more than 1.4 million people across 692,777 businesses, growing at an average 6.5% per year over 2020–2025.
• Mordor Intelligence: $186 billion in 2025, projected to reach $245 billion by 2030 at a 5.7% CAGR.
• Kentley Insights: $167.4 billion in 2024, with 6.4% growth over the prior three years and 150,401 companies in the industry.
• RealGreen / industry aggregates: $159 billion in 2024, projected to grow to $163.8 billion in 2025.
• Statista (IBISWorld): $153.56 billion in 2023.

The differences across these figures aren't material, they reflect minor methodology differences (whether to include snow removal, whether to include certain tree services, residential-only vs. residential-plus-commercial, etc.), but they all converge on the same conclusion: landscaping services is a roughly $160–190 billion industry in the United States, and it's growing meaningfully faster than GDP.

Why this layer is so much larger than retail

Two reasons. First, services involve labor at scale: 1.4 million people working at landscaping firms, each generating somewhere around $164,000 in revenue per year (the Kentley figure). That's a much larger cost basis than retail products move through. Second, this layer includes commercial work (corporate campuses, municipal parks, HOA contracts, hospital and university grounds), which dwarfs residential spending and doesn't show up in any consumer-spending figure.

Per Mordor Intelligence's 2025 report, residential demand accounts for 61% of the US landscaping market, while the commercial segment is forecast to grow at 7.4% CAGR through 2030. Even at 39% commercial, that's a $70+ billion residential layer, already larger than all of Layer 3 retail, before the commercial work is added.

Layer 5: Global landscaping services: $330B+

If you want the largest defensible number, here it is. Grand View Research valued the global landscaping services market at $330.58 billion in 2024, projected to reach $484.79 billion by 2030 at a 6.7% CAGR. The US accounted for 83.92% of the North American share in 2024, and North America is the largest regional market.

This is the figure that gets quoted when consultants want to make an industry sound enormous. It is enormous. But notice what's happened: we've now combined US residential, US commercial, all foreign residential, and all foreign commercial, four categories that have very different growth dynamics and almost nothing in common at the operating level. A consumer brand thinking about its addressable market should not use this figure unless its product has a credible global, B2B+B2C, services-bundled go-to-market plan.

Which number should you use?

The right number depends entirely on the question you're trying to answer. A short field guide:

If you're sizing the consumer audience

Use Layer 2 ($52B–$76B per the National Gardening Association) and combine it with participation figures: roughly 71 million US households actively garden in a focused sense, while the NGA's broader L&G activity definition reaches 122 million participating households. Both measures align with consumer behavior; the former is the dedicated-gardener number, the latter is the everyone-who-cares-for-outdoor-space number.

If you're sizing the retail TAM for a product brand

Use Layer 3 ($50B+). This is the relevant denominator for any consumer brand selling tools, equipment, plants, or branded supplies through retail or DTC channels.

If you're sizing the operator opportunity (services, marketplaces)

Use Layer 4 ($160–190B). This is what's at stake if you're building a marketplace platform for landscapers, a B2B SaaS product for the trade, or a services-aggregation play.

If you're writing a deck for investors

Use multiple layers in sequence. "$52B participatory consumer market within a $50B+ retail TAM, embedded in a $190B services category." This communicates the layered nature of the opportunity and pre-empts the question "wait, but I read it was a $7B industry."

If you're claiming "the world's largest gardening market"

Use Layer 5 ($330B global), but be ready to defend why your business model can capture global services revenue. Most can't.

What the disagreement tells you

The structural reason the same industry produces such different headline numbers is that it isn't one industry, it's a stack of related markets that share a common consumer (the household with a yard or balcony or houseplant collection) but operate through wildly different go-to-market channels: retail consumables, retail durables, professional services, B2B trade. A flagship consumer brand built on the right URL could sit at the top of all five layers, selling consumables, recommending retail products, partnering with smart-gardening hardware companies, referring landscaping services. That's the actual addressable opportunity for an integrated category brand, not any single layer in isolation.

This is the part that the size figures, taken individually, fail to communicate. A $7 billion consumables business and a $190 billion services business sound like different industries. They aren't. They're the same households, paying different vendors for different parts of the same activity. Whoever connects those vendors at the consumer surface captures economics across all five layers, not one of them.

The practical takeaway

Next time you see a market-sizing claim about gardening, ask which layer it's measuring. If the writer can't tell you, the figure isn't reliable. If they can, the figure is probably correct, for whatever question they were trying to answer. The five layers above cover essentially every claim made publicly about the size of the lawn and garden industry, and the framework above lets you slot any new claim you encounter into the right place in the stack.

The headline doesn't matter. What matters is which layer you're standing on when you make a decision.
