A sense of gloom might hit you in the aftermath of the holiday season, but it’s probably not just because you put the string lights away.

There’s a link between shortened daylight hours in winter and seasonal depression. Some 4 to 6 percent of Americans suffer from seasonal affective disorder, according to Washingtonian magazine, while more suffer from a lesser form known as the winter blues or winter doldrums.

Experts say that seeking out sunlight, a healthy diet, exercise, rest and the support of family and friends are ways to combat the doldrums.

Another way to improve your mood – in the winter but really year-round – is to bring nature into your home or workplace in the form of houseplants.

Multiple studies have found that indoor plants make us happier and healthier. It can take fewer than 20 minutes in the presence of plants to make us feel more at peace, according to the Washington Post.

“In one experiment, participants who spent even five to 10 minutes in a room with a few houseplants felt happier and more satisfied than those in a room without plants. In another study, participants felt more peaceful and positive after spending 15 minutes in a room close to a tall plant (about five feet) compared with other objects.”

Even post-pandemic, we spend most of our lives indoors. Houseplants make us feel more connected to the world outside and help our mental and physical health in many ways.

Reduce stress and anxiety

Time reported on a study in which researchers asked participants to re-pot a houseplant or complete a computer-based task.

“After working with plants, people reported feeling comfortable and soothed, and their blood pressure dropped. The computer task, on the other hand, caused them to feel uncomfortable and ‘artificial,’ and was associated with a spike in blood pressure and sympathetic nervous system activity.”

The stress hormone cortisol, which is found in saliva, decreases when we are around plants.

Reduce depression

Houseplant sales spiked during the pandemic, helping people with their depression, anxiety and “sad days” of isolation, according to one seller of succulents and air plants. That sentiment jibes with a study conducted during stay-at-home orders in Bulgaria. People who had houseplants or a garden “experienced fewer symptoms of depression and anxiety than those who did not,” according to Time.

Introducing plants into your home enhances your mood and helps with loneliness and depression, NBC News reported, noting that “caring for a living thing gives us a purpose and is rewarding – especially when you see that living thing bloom and thrive.”

Improve air quality

Houseplants “essentially do the opposite of what we do when we breathe: release oxygen and absorb carbon dioxide,” according to NBC News. “This not only freshens up the air, but also eliminates harmful toxins.”

NASA found that houseplants can remove up to 87 percent of air toxins in 24 hours.

Increase productivity

Multiple studies, according to Time, concluded that plants boost productivity: College students worked 12 percent faster when plants were added to a windowless computer lab; employees at a call center who had a view of plants made up to 7 percent more calls per hour than colleagues who couldn’t see plants; office workers were 15 percent more productive when plants were introduced into their workspace.

From Psychology Today: “Students and employees with a view of nature, either indoors or right outside their windows, were not only found to be more productive but also more alert, more attentive, more relaxed, in better moods, and less irritated by physical symptoms of allergies and asthma than their counterparts who had no views of plant life or other natural settings.”

Of course, winter eventually will give way to spring, but houseplants will ensure that you receive the benefits of nature no matter the time of year or the conditions outside.

To understand how flower growing has changed in the past four decades, consider 1, 7 and 9.
Those numbers identify the three remaining greenhouses at Royer’s corporate complex in Lebanon. As the breaks in number sequencing suggest, Royer’s had more greenhouses back when we grew our own flowers – nine total at the corporate complex and six more nearby on Colebrook Road.

However, a perfect storm occurred in the 1970s: An oil embargo made it prohibitively expensive for Royer’s and other florists to heat their greenhouses, while Bogota, Colombia was found to offer ideal temperatures and sunlight for growing flowers. In the intervening years, most flower growing has shifted to South America.

Today, as Tom Royer, CEO, pointed out, Royer’s isn’t a grower but rather a holder of plants. That is, the company buys from growers both inside and outside the United States. Those plants and flowers are delivered to the corporate complex, where they reside before being distributed to Royer’s 16 stores in seven counties.

Much of the “holding” occurs in the three greenhouses which houses equipment designed to improve plant quality and operating efficiency.

TURN OF A TIMER

Over the past few years Royer’s has installed new flood tables in each of its remaining greenhouses. This automatic plant watering system isn’t new to Royer’s though, the company has utilized this technology since 1999.

Each flood table has its own water reservoir. Once per day, we turn on a timer that floods the table for typically 15 minutes but longer if external conditions warrant. The plants, lined up in rows, drink through openings in the bottom of their containers.

Drip Irrigation systems are also utilized in the greenhouses, specifically for when we have hanging baskets, such as around Mother’s Day. Each water line is placed in or above a hanging basket and when turned on, the water will slowly be absorbed into the soil.

With both systems, a worker doesn’t have to tend to each plant individually, a time-consuming proposition considering the hundreds of containers.

“Now I can water all these plants in 15 minutes,” Tom said, “whereas it would take somebody two or three hours to do that day after day after day.”

CONSERSVING WATER

The reduced labor also will improve quality, as watering won’t ever have to be sacrificed for the sake of other time demands. (In some cases, watering from above can cause damage, such as stains on violet petals.)

Of course, not all plants need the same amount of water.

“Just like people, they drink different, they eat different,” Tom said. Reflecting those differences, Royer’s separates plants by type (all violets on one bench, for instance) or at least by pot size and waters them accordingly.

Water that isn’t absorbed by the plants goes back into each table’s reservoir so it can be conserved and reused.

Another greenhouse variable is sunlight. In greenhouse 7, which holds blooming plants, a system of cables and pulleys operates the fabric shade cloths. By controlling the amount of sunlight, Royer’s can maintain an internal temperature of 75 degrees.

“If these shade cloths weren’t on here,” Tom noted on a warm, sunny day in early October, “it would be a lot hotter in here.”

Tom said the expenditure on flood tables and the shade system are the price of doing right by customers.
“It’s an investment in the future,” he said. “It’s worth it to me to do that because long term I’m going to have better product. It’s going to be taken care of properly. It will grow better, too.”
