How Many People Garden?

Research by Scotts Miracle-Gro and Wakefield found that over half of the country, 55% of American households, are engaged in gardening activities.

This translates to 71.5 million gardening households, or 185.9 million people, ranking the U.S. among the top 3 gardening countries worldwide, preceded by Australia and China.

In 2021, 18.3 million households started gardening, and 42% of all gardeners spent more time on gardening activities. However, it remains to be seen whether these trends, which developed during the Covid-19 lockdown, continue.

Gardening Health Benefits

As an exercise, gardening is comparable to biking, walking, or jogging. Gardening activities, such as pulling weeds, strengthen cardiovascular health, and increase muscle tone and dexterity.

Additionally, multiple scientific studies linked gardening to emotional well-being and an increased sense of accomplishment and happiness.

Here're some of the key findings from research studies by UNC Health and Princeton University:

  • Gardening fosters self-esteem and a sense of accomplishment.
  • Gardening relieves stress, anxiety, and depression.
  • Gardening increases the level of vitamin D, vital for the normal functioning of the immune system.
  • Gardening increases the level of serotonin, a brain chemical responsible for the feeling of happiness.

How Much Does Gardening Cost?

An initial gardening investment usually includes seeds, soil, fertilizer, and gardening tools.

Gardening tools and planting seeds are usually inexpensive. For an average-sized food garden, the tools cost around $100, and the seeds cost about $2.8 for 50 seeds, on average. The cost of soil ranges from $534 - $2400, depending on the type of plants and the depth of soil required for these plants.

The annual garden maintenance costs are less significant. The National Gardening Association estimates that U.S. gardening households spend an average of $70 on maintaining their gardens.

The same study determined that the average garden yielded $600 worth of produce (roughly $1 per square foot), resulting in a $530 average return on gardening investment or a 757% ROI after the first-year startup costs.

Most (and Least) Cost-Effective Foods to Garden

To understand whether a food plant is a good investment, we should consider the planting costs, added care (if any), and how much the plant would produce.

For example, gardening strawberries or asparagus in the yard is not a good investment, as they are expensive to plant, require extensive care, and don’t produce much food per plant.

On the other hand, growing tomatoes, zucchini, or summer squash are great investments, as these vegetables cost little to plant, require almost no extra care, and produce abundant food.

Here’s the breakdown of planting costs vs. returns for some of the most popular foods in U.S. gardens.

PlantCost of SeedsHarvest ValueROI
Green beans $2.10 $10.68 508.6%
Zucchini $3.00 $12.40 413.3%
Summer squash $3.00 $12.40 413.3%
Blueberry bush $13.30 $38.70 291.0%

How Much Time Does Gardening Take?

Gardeners spend 5 hours a week on average tending to an average-sized garden.

The average size of a U.S. garden is 600 square feet, while the median garden is 96 square feet or 12 feet by 8 feet of ground.

In other words, while 50% of the U.S. gardens are 96 square feet or smaller, some gardens are bigger than 600 square feet (for the 600 sq. ft average to remain true).

100-200 sq. feet of the food garden space is sufficient to feed one person with the garden produce year-round.

Here’s the table showing the minimum time commitment required for food gardens of different sizes and the number of people they can feed.

Garden SizeHours/WeekPeople Fed/Year
100-199 sq.ft. 0.5-1 hr 1 person
200-399 sq.ft. 1-2 hrs 1-4 people
400-799 sq.ft. 3-5 hrs 2-6 people
800-1499 sq.ft. 4-6 hrs 4-8 people
1,500-2,000 sq.ft. 6-8 hrs 6-10 people

Professional Gardening Services

While most people see gardening as a DIY project, professional gardening services are also available.

A professional gardener can help select plants, flowers, or trees that grow well in soil conditions and with the amount of sunlight available in the garden. Planting services range anywhere from $47 to $2,000, depending on the size and scope of the project.

Professional gardeners can also be hired for weed control and soil fertilization for $65-$90 per service.

A weekly professional gardener costs $35-$80 per week, or $1,820 - $4,160 per year, making the home garden less cost-efficient but, perhaps, more doable.

The Best Regions for Gardening


The U.S. South has the most gardens per capita, followed by the Midwest and West regions of the country.

RegionPercent of Food Gardens
South 29%
Midwest 26%
West 23%
Northeast 22%

Source: Garden Research

This somewhat even distribution per region demonstrates people’s willingness to garden no matter where they are – in Florida, where the growing season is year-round, or New York, where gardening is limited to just five months a year due to the weather conditions.

Best States for Gardening

Generally, the best places for gardening have softer climates (no drastic temperature changes or severe freezing), richer soils, longer growing seasons, and a large variety of plants that are well-adapted to the state’s growing conditions.

Based on these criteria, the best states for gardening (in no particular order) are:

  1. Alabama
  2. Arizona
  3. California
  4. Florida
  5. Georgia
  6. Hawaii
  7. Louisiana
  8. Maryland
  9. Mississippi
  10. Nevada
  11. North Carolina
  12. Oklahoma
  13. Oregon
  14. South Carolina
  15. Tennessee
  16. Texas
  17. Utah
  18. Virginia
  19. Washington

The average minimum winter temperature remains above 10 degrees Fahrenheit in all of these states resulting in milder winters.

Growing seasons differ by state, with the shortest season of 9 months (March – November) and the longest of 12 months (January – December), allowing for multiple crops within the same season.

All states listed above belong to Zone 8, 9, or 10 of the USDA Hardiness Zone Classification and are geographic areas defined by a milder climate relevant to the successful growth of many vegetables, fruits, and herbs.
