How Drones Can Benefit Tree Nurseries: Counting and Checking Stock

How can drones benefit tree nurseries?

Drones for tree nurseries do one job that matters more than most people expect: they count and check stock across ground that is slow to walk. A grower with seedling beds, container blocks and field-grown trees spread over many acres usually knows the numbers only in pieces. Someone walks a block, samples a few beds and estimates the rest.

A drone changes that. Flown at a steady height over the stock, it captures whole blocks in images that software can count, size and compare from one flight to the next. The practical benefits follow from that: counts that cover full blocks, growth tracked across repeat flights, and sparse or stressed areas that show up on a map before a crew reaches them.

The drone does not replace the people who grow and move the stock. It gives them a fuller picture of where their walking time should go. The sections below cover the problem today, how a drone works on a nursery day to day, which parts of the operation it covers, how it fits with your crew, what drives any savings, what it cannot do, and how to get started.

Why is stock counting so slow at a tree nursery today?

Counting is one of the most labor-intensive jobs on a nursery. A 2024 study in the journal Smart Agriculture described manual, on-site surveys of individual plants as labor-intensive and time-consuming, and it proposed a deep-learning model that reads aerial images to locate, size and count dense nursery stock. The problem is easy to recognize on the ground: rows run long, blocks sit far apart, and a hand count is only as good as the hours someone can spare.

The sector itself is large and spread out. According to the Agricultural Marketing Resource Center, 6,458 operations were producing nursery stock in the 2019 Census, a decline of nearly 2,000 since 2009. The 2014 Census had counted 5,963 farms producing primarily nursery stock, the largest of 17 horticulture farm types. Fewer operations remain, but each one still has to know what is in the ground.

The wider horticulture sector is bigger again. According to the USDA National Agricultural Statistics Service, the 2024 Census of Horticultural Specialties counted 23,060 horticulture operations.

What are the main benefits of drones for a tree nursery?

The biggest benefit is coverage. A drone can image an entire block rather than a sample of beds. An Oregon Department of Agriculture inventory project, run with university partners, was set up to automate inventory counts at container and field nurseries in a cost-effective way.

Accuracy is the question growers ask first. In a 2017 project reported by a university extension team in Michigan, the tree inventory was over 97 percent accurate when the drone flew within 200 feet above the trees. That was one project with its own settings, so it shows what careful flight planning can deliver, not what every nursery will get. The benefits cluster in four areas:

• Counts across full blocks in place of hand counts from sampled beds.
• Estimates of trees per acre and nursery stock height from the same imagery, according to Digger magazine.
• Health checks on field-grown trees that show stressed areas on a map.
• Repeat flights that show growth from one check to the next.

How does a drone work on a nursery day to day?

The routine is simpler than the technology suggests. Someone on staff marks the blocks, picks the rows to cover and sets the flight height. The drone flies the pattern and records images. Software then locates and counts plants, using the same basic approach the 2024 study described for dense stock.

The method is not limited to one kind of tree. A Finnish study in the MDPI journal Forests found that consumer drones with deep learning gave a cost-effective and accurate aerial inventory of spruce seedlings.

After each flight, the results come back as a map and counts that the crew reviews. People who know the stock check flagged areas on foot, confirm what the imagery shows and decide what to do next. Repeat flights over the same blocks show growth across the season, which is the part that is hardest to see on a walk-through.

Which parts of a tree nursery can a drone cover?

A tree nursery is not one kind of space, and the drone's work changes with each. Container blocks, field blocks, seedling beds and field-grown trees each present a distinct counting or checking job. The Oregon project tested low-altitude aerial imaging at both container and field nurseries, so the approach was checked across more than one layout.

Seedling beds benefit most from full coverage, because a sample taken from a few beds can miss gaps and uneven stands. Field-grown trees add a second job: checking canopy health and spotting stressed areas across acreage that would take a long time to walk.

How does a drone fit alongside existing staff?

A drone does not replace the nursery crew. The best results come from pairing it with a smaller team that knows the stock. Growers and foremen set priorities, decide which blocks get flown and act on what the imagery shows. Hand work stays with people, including planting, potting, moving stock and treatment decisions that need someone standing in the row.

We pick the right unit for your site, lease it through financing, deploy and integrate it, train your staff and service it nationwide. Training covers flight planning, reading results and knowing when a flagged area needs a walk, so your people stay in charge of the decisions.

Staff time moves from long walks to planned flights and reviews. The counting still needs people to judge what the results mean, and that judgment is where experienced staff add the most.

What drives the savings at a tree nursery?

Savings come from hours. Every hour a crew does not spend walking rows to count is an hour it can give to planting, moving stock or fixing irrigation. How much that adds up to depends on how much counting and checking your operation does, how many blocks it covers and how often.

The best sourced figure comes from Digger magazine, which quoted a college specialist saying a 10 to 20 percent labor saving would be significant. That is an expert view, not a measured result from a specific nursery, so treat it as a planning range rather than a promise.

We do not promise a saving in any number of hours. The real figure depends on block size, flight frequency, how much ground checking your team still does and how quickly the crew reviews results. A site assessment gives you a clearer picture than any general range.

What can a drone not do at a tree nursery?

A drone sees what is visible from above. It can count the tops of plants and measure canopy from the air, but stock under dense cover, inside tight canopies or hidden by structures still needs a person on the ground. Counts are strongest when imagery is clear and the flight is planned well.

Weather and light limit flying days. No flight replaces the agronomy, pest decisions or irrigation management that a grower carries. The imagery shows where something looks wrong. It does not always show the cause, so the crew still has to confirm what the image suggests before acting on it.

Even the Michigan accuracy result came from one project with specific flight settings. Check your first counts against a small ground sample before relying on them for orders or planting plans.

How do you get started with drones for tree nurseries?

Start with a free site assessment. We map your blocks, identify the counting and checking jobs that matter most and look at where a drone would fit. Many growers begin with one leased unit and a pilot program on a few blocks, then widen the flights once the team trusts the results.

The drone is leased through financing programs. The fixed lease payment comes in the quote, which we prepare after the site assessment, so you can weigh it against the hours your crew saves.

After go live, we provide on-site dispatch when a unit needs attention and remote triage to sort issues before a visit. You get one partner and one number for deployment, training and service across the country. Drones for tree nurseries work best when the first flights are small, the ground checks are planned and the service is close at hand.
