Drone ROI for Tree Nurseries: Counts, Hours and Payback

What return can tree nurseries expect from drones?

A tree nursery lives on its stock counts. Someone has to know how many plants of each species and size sit in each bed, because shipping schedules and sales depend on that number. Counted by hand across acres of beds, a full pass means crews walking every row. A drone flies the rows and captures images, and those images are used for counting and plant health checks. The return comes from the walking hours that come off the crew's day, plus earlier notice of stock that is struggling.

Drone ROI for tree nurseries is a range, not a fixed figure. It moves with how much of the yard a drone can cover in your conditions, how many hours that coverage removes, and what the lease costs over its term. The sections below explain each part, so you can test our range against your own acreage and schedule.

How big is the nursery counting job?

The scale is large and still growing. According to the USDA Economic Research Service, summarizing the 2022 Census of Agriculture, about 10,800 commercial farms grew cut flowers and florist greens in 2022, up more than 50 percent from 2017. Roughly 31,000 acres were in open-field flower production that year, up about 33 percent from 2017. These figures describe a neighboring segment, not tree nurseries, but they show how fast outdoor acreage is growing.

The Purdue Landscape Report, drawing on the census of horticultural specialties, counts 23,060 horticultural operations nationwide. The same report reports nursery stock sales up 17 percent from 2019.

Labor is the other pressure. The 2022 AmericanHort Greenhouse and Nursery Labor and Employment Survey, run with UC Davis and Michigan State, found that nearly two thirds of respondents could not hire all the employees they wanted in 2021, and 35 percent used the H-2A program in 2021. A Canadian employer survey from the Canadian Agricultural Human Resource Council, covering 2022 data, reported an 18 percent turnover rate in nursery, floriculture and ornamentals, against 4 percent for greenhouse fruit and vegetable growers. That is Canadian data, so treat it as a signal, not a US benchmark.

Where does the return come from: counts and health checks?

Counting is where a drone earns its place. Researchers in a collaboration involving Arkansas, Florida and Oregon imaged container and field nursery stock from aerial platforms. A count from stitched video at one Florida nursery was reported as 98 percent accurate, according to a nursery plant inventory project document hosted by the Oregon Department of Agriculture. The same document notes that during shipping season, plant rows begin to look like Swiss cheese, which makes human counts difficult.

Other work points the same way. According to a trade magazine feature on growing from above, a Michigan State study on Christmas trees and arborvitae found inventory over 97 percent accurate when the drone flew within 200 feet. That study covers conifers, so its figure says more about the method than about your species mix.

Ongoing research is still open. Mississippi State's June 2026 project is training an AI model on drone footage of nursery stock, starting with magnolias, with inventory as phase one. Researchers visited three South Mississippi nurseries, and the work has no results yet. Treat the accuracy figures above as earlier results under specific conditions, and have your site assessment test accuracy on your own rows.

Health checks are the second use. Overhead images show canopy color, thin patches and gaps, so crews can walk only the flagged beds instead of the whole yard. We did not find a verified accuracy figure for health detection, so this page gives none.

How does the ROI math work?

The calculator starts with the hours a count or inspection takes now, then applies the share of that work a drone can realistically fly. Three inputs carry most of the weight: acreage and row layout, the number of passes per season, and the share of rows that are flyable in your conditions. Each input is entered as a range, so the savings output is a range too.

On the labor side, the drone's hours are priced against the government wage data on this page for Security Guards. A drone flying a fixed route resembles the monitoring side of that job, so the calculator values the hours it takes over on that wage. The people who count stock do a separate job, and we do not price their time. The calculator's default crew of two is our assumption, not a published figure, since we found no published count of stock-counting staff per nursery site. Replace it with your own crew size.

On the cost side, the robot is leased through financing, and the payment is fixed. A fixed robot lease payment is quoted after a site assessment. The return is positive when the hours the drone takes over, valued on that wage, exceed the lease payment and the service the unit needs over the lease term. Read every savings range against that comparison.

What changes the number up or down?

Four things move the answer most. Open rows that a drone can see into raise the flyable share, while dense canopy and covered structures lower it. More counting passes per season raise the hours a drone can take over, because each pass repeats the walk. Larger and irregular yards need more flights, and flight time is limited. Finally, the hours your crew really stops doing decide the return, so an hour that is reassigned rather than dropped counts for less.

Use the checklist below before you accept any savings range. Each item is something the site assessment should measure, not assume.

What are the risks to the return, and how do you avoid them?

Weather is the first risk. Wind and rain limit flight days, so the number of usable flight days in your season sets how many passes you can run. According to the trade magazine feature, drone flight time is usually up to about 40 minutes, maybe 60 in excellent conditions. Plan routes in batches that fit that window, and ask for the weather-day count in your assessment.

The second risk is overstating the savings. A grower quoted in the same trade feature said that saving 10 to 20 percent in labor would be significant. That is a useful bar. Set expectations as a share of the hours, not a headcount cut, and check the range against a measured pilot before you commit to a lease term.

The third risk is accuracy under canopy and in shipping gaps. Earlier results were strong under the conditions studied, but a plant missed under dense foliage is a count you did not get. Agree on a sample check with your crew, compare drone counts against hand counts on a few beds, and adjust the route or altitude before scaling up.

Injury rates are context, not proof. The BLS crop production page reports a total recordable injury and illness rate of 4.1 per 100 full-time workers, with days-away cases at 1.4 per 100 and job restriction or transfer cases at 1.1 per 100. The page does not state the year, and it covers crop production as a whole, so it does not show that drones make a nursery safer.

How long does it take to pay back?

The timeline runs in stages. First comes the free site assessment, which maps the beds, samples flights on a few rows, and measures the flyable share. Next comes a quote for a fixed robot lease payment and a savings range. Then routes are set up and staff are trained. Many operations start with one leased unit and a pilot on part of the yard before extending coverage.

Payback is the point where cumulative hours saved, valued on the government wage data on this page, cover the lease and service cost. The date depends on how many passes a season needs and when peak shipping falls, so the first full season is the real test. We deploy and integrate the unit, train your staff, and service it nationwide, so the pilot has one partner handling deployment, training and service.

Why do labor numbers make drones worth testing?

Labor is hard to fill in this industry, so the hours a drone covers carry more weight than the raw saving. The AmericanHort result that nearly two thirds of respondents could not hire all the employees they wanted in 2021 shows the staffing pressure. The Canadian turnover figure of 18 percent for nursery, floriculture and ornamentals, against 4 percent for greenhouse fruit and vegetable growers, suggests that keeping staff is harder in that segment. Both are reasons to test the work, not proof that it will pay.

How do I get a precise figure from a free site assessment?

A precise figure needs your numbers. The assessment collects your acreage and bed layout, how many counts and inspections you run per season, the hours each takes now, the weather days you can fly in, and the lease term you want. Then the site is mapped and sample flights measure the flyable share and image accuracy on your stock.

The output is a savings range built from those measurements, plus a lease quote for a fixed robot lease payment with service terms. We pick the right robot for the site, lease it through financing, deploy and integrate it, train the staff, and service it nationwide. Bring your count sheets, your crew schedule and your bed map, since those three documents shorten the first visit.
