How retailers and growers can get better margins from plants.

July 11, 2018

Consider the five dimensions of value when pricing your plants. For example, succulents carry “social value,” or, if people who are socially important to your customers have succulents in their homes or lawns, your customers will also want to have succulents to feel they are on trend.

I don’t get fan mail, but I did receive an interesting email from an independent grower not that long ago.

He wrote, “Now that the busy season is almost over, we are delving deeply into planning for next year. We are going into our third season of growing in our greenhouse, and of course, pricing is an issue that never goes away. We find it very difficult to feel as though we are making enough profit, yet staying competitive in the market. We have attempted to work some formulas for pricing, but don’t feel very confident in our numbers. This is generally pointed at materials we start from plugs, but there is a whole different set of circumstances when we look at vegetables and herbs we grow from seed. Previously we kept our seed-grown plants at a lower price point, because we felt we had less expense incurred with them and could use them as a price leader; however, recently I read another article that said basically, if a grower makes money from growing, and a retailer makes money from selling, as a grower/retailer, we should be making more, not less profit from what we grow ourselves.”

Pricing is a tough subject to tackle for a few reasons. First, many people don’t have a good idea of their costs. Second, math often isn’t as much fun as growing plants. Third, there is as much art to pricing as science. If you can stomach the math, it will help. It isn’t calculus, but it does take time. It sounds like cost calculations are a real issue for this company and probably a great many others. But, cost is only one piece of the puzzle or, more likely, only one type of chessman on the chess board. Pricing profitably is important not just to cover costs, but to have a financially viable firm.

Grower-retailers, what are your costs?

For any business, one of the first challenges is to get a good idea of your costs. How are you keeping track of them and how much detail do you have? I think it first takes a commitment to track costs, and then it takes the investment of time. Michigan State published a cost accounting system (adapted to Excel) for greenhouse producers. There are some great resources available online (see side bar on page 37). The key is to find a system you can use and then commit the time to use it.

If you’re starting from scratch, start small by dividing expenses into two piles: what you spend into direct and indirect costs. Direct goes into production or selling, and indirect is overhead or everything else that didn’t go directly into selling. No one person has “the” perfect system for dealing with costs, and the hardest part is getting started. Pick three or five key products and begin with them. If poinsettias, four-inch annuals, and 12-inch baskets are key products for you, that’s where you start figuring your costs. Make an effort to re-visit those costs at least twice each year, working to put more detail into those costs. The more you work at it, the more concise your costing system will become. The trick is to not try to make it very detailed at the start, but work toward more detail as you get more comfortable with the system of tracking costs.


If you’re already tracking costs, the next step is the level of detail. The question posed by the writer of the email mentioned at the beginning of the article was one of comparing seedling and cutting plants. If you want to know how much you’re making on seedling plants vs. plants from cuttings, you’ll need to delve into the costs to see how those differ. Then you can calculate how much margin you’re making on both. What are the direct costs for seedlings and cuttings? It’s likely that the same direct costs for containers, tags, media, fertilizer and other chemicals will be the same. What’s the difference? It is the seed and cutting cost. So, if you can get a system into place to track costs per container, you can vary the plant that goes into that container. Then, compare prices, and you can calculate the difference in profit. The same holds true for baskets and other containers. You likely use the same type and amount of media, tags, and chemicals in identical containers, but the plant material that goes into them may differ in cost.

Labor is another piece of direct cost that can be tough to allocate. Labor is most often the single largest expense for growers and retailers. Again, I’ll highly encourage people to put labor in, but the level of detail can be developed over time. It can be tough to track labor directly related to production (versus retail) but, again, do the best you can. Start simply and try to determine total labor hours/dollars that went toward production. How much more detail can you develop from there? Can you divide that by crop or by number of containers grown? Making simple steps toward achieving better detail is more helpful than doing nothing at all.

Five dimensions of value

Is cost the only input to calculating price? No way! Sheth et al. (1991) proposed that consumers make their product choices based on five dimensions of value: functional, conditional, social, emotional and epistemic value.

Functional value is how well something does its job. Butterfly weed (Asclepias) is great at attracting pollinators. It has high functional value compared to many other plants.

Conditional value is the symbolism or meaning of a product; red roses mean love to most of us.

Social value is how the product makes us look to others who are socially important to us. If our friends have succulents in their apartments, we can look cool if we do also.

Epistemic value is the novelty or sensory value. Is it a new color of carrot? Is it a fragrant plant? If yes, then it’s got higher epistemic value.

Emotional value: Dr. Charlie Hall, professor and Ellison Chair in International Floriculture at Texas A&M University, and Madeline Dickson, environmental scientist at Leaaf Environmental, published an article in 2011, when Dickson was still a student at Tulane University, that summarized the economic, environmental and well-being benefits of plants. That article is full of research showing the positive feelings that plants inspire, and the stress that plants can help mitigate.

Yet, when we consider pricing plants, we don’t tend to think about all these components of perceived value. All the dimensions of perceived value can’t be calculated in the cost accounting, but are extremely important in setting a price.

Considerations for pricing at retail

Next, let’s talk about what most people really buy. Most savvy marketers agree that people buy the benefits, not features or characteristics, of products. For example, you buy a high wattage (product feature) microwave oven because it will cook food faster (benefit). You buy a personal computer with more gigabytes (feature) so you can store more music and videos; you buy a PC with more RAM (feature) so your games run faster (benefit). Consumers buy a deciduous tree (feature) to shade their home and reduce cooling costs in the summer (benefits). Consumers buy basil and parsley in four-inch containers (feature) because they are small enough to carry but ready for eating with fresh tomatoes (benefit). We used Hall and Dickson’s 2011 article in a recent study to show that signs with product benefits helped to sell plants at a premium price, while the combination of features and benefits helped sell plants at more moderate prices (Zhu et al., 2017). So, while setting the prices of your products, consider product benefits. Benefits can help you with the evidence that plants are worth more than the cost of production.

Price points are important as well. Manning et al. (2009) published the effects of product choice when a price ended in a number “open” to the left (3, 5, 7, and 9) versus numbers open to the right (2, 6). People tend to buy products that end in numerals pointing to the left. They create price points that are perceived to be a better “deal,” as $4.99 is considered to be a better deal than $5.00. It’s also pretty simple math to see that a retailer who prices products at the $0.99 increment (as compared to $0.97 or $0.95) can get two to four cents more simply by using the highest integer possible (9). Why would you leave those few cents on the table?


The art of pricing comes into play with considerations such as: how much farther can you push the margin, still appeal to a broad base of your customers and continue to drive profits? Most businesses have a fear of increasing prices, but if selling a product is costing the business money, disaster isn’t far away in this climate. The late Dr. Will Carlson, who was Professor Emeritus of Floriculture at Michigan State University, once told me, “Costs are critical. You don’t want to lose money after you’ve worked so hard. Do you want to tape a nickel to each container you sell, or do you want to generate some profit?”

Price elasticity

The last part of the art of pricing comes from a study that Drs. Charlie Hall, Marco Palma, assistant professor and extension economist in the Agricultural Economics Department at Texas A&M AgriLife Extension Service, and I conducted a few years ago. With the assistance of some high-caliber retailers, we devised a study to examine price elasticity or, more simply, how much does demand rise or fall when we decrease or increase prices? What we asked them was to really go against convention, and rather than decrease prices over this selling period, we asked them to increase prices over the selling period. This was over a period of four weeks during their busy season.

The first step was to identify products that were similar in terms of the plant material but had an element of differentiation. For this, we used both national brands and in-house brands and compared them to unbranded products. If you think about the branded plants as the test plants and the unbranded or generic as the control plants, what we did was to vary the price of the branded plants over time while the price of the control or the generic plants was stable across the four weeks of the study.

For the first week, the control plants were at a certain level, but the branded or the test plants were actually priced 10 percent lower than the control or the generic plants. Then in week two, we increased the price of the test or the branded plants to make them at the same level as the test plants or the generic plants. Then in the third week, we increased the price of the test or the branded plants to 10 percent over the price of the control or the generic plants. So, the branded plants were, in week one, 10 percent lower; in week two, the same price as, and then in week 3, 10 percent higher than the unbranded or the control plants.

Roses can be priced considering not only the cost to produce them, but for their conditional value; i.e., the fact that roses symbolize love.

We conducted this study on a wide range of plants, including roses, annuals, perennials, shrubs, and vegetable and herb transplants. We had a great deal of data to examine the impact of this price increase, particularly when we knew that the prices of other products, or at least the perception of the prices of other products, was going to be going down over the study period. What were the results?

The great news was that when we raised prices by 10 percent per week, in spite of selling 8.27 percent fewer units, total revenue was actually up 2.3 percent. In other words, even though we sold fewer units, the increase in price enabled the retailers to sell about 2.3 percent more in terms of overall revenue. We increased revenue even though we decreased the number of units. Wouldn’t you like to earn more revenue and work less hard?

Don’t apply a “one-size-fits-all” approach when pricing

Pricing is art and science, and so is raising prices. It’s going to be much easier to raise prices on products that are easily differentiated (perceived as being different). This is one of my big “beefs” with pricing all containers at the same price point. We are giving up the perceived value dimensions and the real product benefits and telling the consumer that the value lies only below the rim of the container. Sure, it makes life easier for labor (which is hard to find and retain), but we cannot remain profitable and financially sustainable if everything is priced by container size.

If you’ve not begun this mathematical adventure, remember to start by focusing on three or five key products that can be differentiated with benefits and/or higher perceived value. Start at a low level of detail and build to a more detailed system. Delve into your costs to find out how much key products really cost to grow.


Then, engage in the art of pricing. How much does it cost you to sell them (primarily labor, but also facility cost)? How much are you making in profit? If you aren’t making much, how much more could you charge? Could you consider raising prices? The consequence of not improving the margin is giving that away. Are you prepared to send some of your hard-earned cash out the door? If you can’t make more money by raising prices or lowering costs, it may be time to think about not growing that product. After all, do you want to work to give your money away?

Take proactive steps to get a handle on your costs and incorporate perceived value in some products that can be easily differentiated to boost your bottom line. Your employees, investors, customers, and partners will be glad you did.
