There is a peculiar moment every spring when gardening suddenly becomes urgent.

For weeks, perhaps months, the customer has known spring is coming.

They have seen gardening magazines.

They have walked past bags of soil.

They may have talked about replacing the shrubs beside the deck.

They know, intellectually, that another gardening season is approaching.

Nothing happens.

Then one Saturday morning something changes.

The temperature climbs.

The sun appears.

Someone opens the back door, steps outside and looks at the yard.

The patio suddenly seems empty.

The flower bed looks neglected.

The neighbours are outside.

Someone starts a lawn mower.

The barbecue comes out.

And a thought that has been dormant for six months suddenly becomes remarkably important:

I need plants.

By noon, the garden-centre parking lot is filling.

What changed?

The garden did not suddenly appear.

The homeowner did not acquire new information about horticulture.

The plants did not become biologically more useful between Friday evening and Saturday morning.

Something happened inside the consumer.

Spring stopped being a date.

It became a state of mind.

For horticultural retailers, that distinction may be worth a great deal of money.

Consumers Do Not Buy Spring on a Calendar

The horticultural industry loves calendars.

Week 14.

Week 16.

Week 18.

Crop schedules.

Ship dates.

Production windows.

Delivery programs.

Mother’s Day.

May long weekend.

We have to think this way.

Commercial horticulture requires months of planning.

The customer has no such obligation.

Their calendar is psychological.

Spring does not begin because an astronomical event occurred on March 20.

Spring begins when the customer experiences something that makes gardening feel relevant again.

Warmth.

Sunshine.

Longer evenings.

The first coffee on the patio.

The neighbour working in the yard.

The first flowering tree.

The smell of freshly cut grass.

These experiences awaken projects that were already somewhere in the consumer’s mind.

The fascinating economic question is what happens next.

The Strange Power of Today’s Weather

In 2007, economists Michael Conlin, Ted O’Donoghue and Timothy Vogelsang published a fascinating study involving catalogue purchases.

They examined orders for cold-weather clothing.

You might expect someone purchasing winter clothing to think about all of the weather they are likely to encounter while owning it.

Consumers did something rather less rational.

Their decisions were influenced by the weather at the moment they placed the order.

When temperatures were unusually cold, people behaved as though cold-weather products were more attractive.

More interestingly, the researchers found evidence that these weather-influenced purchases were subsequently more likely to be returned when conditions changed.

The phenomenon is connected with what behavioural economists call projection bias.

Human beings are not especially good at imagining how different we will feel later.

We understand, intellectually, that conditions will change.

But the way we feel now has an outsized influence on the way we imagine the future.

Cold today makes cold tomorrow easier to imagine.

Heat today makes heat tomorrow more vivid.

And sunshine today can make a garden project that seemed irrelevant yesterday feel suddenly urgent.

This is not really about weather.

It is about imagination.

The Convertible Problem

A second piece of research makes this even more interesting.

Meghan Busse, Devin Pope, Jaren Pope and Jorge Silva-Risso analyzed more than 40 million automobile transactions.

Cars are long-lived products.

Someone purchasing a vehicle today may own it through hundreds of different weather conditions.

Which should make today’s weather relatively unimportant.

It wasn’t.

Convertible purchases increased when the weather was unusually warm.

Four-wheel-drive vehicles became more attractive when snow was unusually prominent.

The researchers considered several possible explanations and concluded that psychological mechanisms including projection bias and salience were consistent with the patterns they observed.

Think about the absurdity of that for a moment.

A vehicle might remain in the driveway for eight years.

Yet the weather during a tiny portion of one afternoon can influence which vehicle seems attractive.

Now consider a plant.

The psychological connection between current weather and gardening is far more immediate.

Sunshine does not simply make a rose more attractive.

It changes the context in which the rose is being imagined.

Yesterday:

Plant.

Today:

That would look fantastic beside the patio.

The product has acquired a future.

Weather Changes What We Can Imagine

This may be the most useful way for horticultural retailers to think about weather.

Weather changes the ease with which consumers can imagine certain outcomes.

On a warm spring afternoon, it becomes easy to imagine:

sitting outside

planting the border

harvesting strawberries

cutting flowers

improving the entrance

filling patio containers

watching something climb the fence

spending the weekend in the garden

The physical environment is supplying part of the marketing message.

A rainy three-degree April morning tells a different story.

The consumer can still understand logically that gardening season is approaching.

But the future garden requires more imagination.

And imagination takes effort.

Retail demand therefore has an emotional component that our production calendars cannot capture completely.

The product might be equally available on both days.

The consumer is not equally receptive.

Demand Can Exist Without Being Active

This leads to an important distinction.

There is latent demand.

And there is activated demand.

A homeowner might have every intention of gardening this year.

They may even have specific projects planned.

Replace the rose.

Plant blueberries.

Fix the border.

Add colour beside the deck.

Those intentions can exist for months without creating a transaction.

Then something activates them.

Perhaps it is the first beautiful Saturday.

Perhaps Easter weekend.

Perhaps Mother’s Day.

Perhaps opening the cottage.

Perhaps having friends over next weekend.

Perhaps seeing the neighbour suddenly working outside.

Perhaps the first evening warm enough to sit on the deck.

The customer’s underlying need did not originate at that moment.

The moment released it.

This is critical for seasonal retail because intent is not revenue.

Activated intent is.

Retail Sales Do Not Move Smoothly

Businesses like averages.

Averages behave themselves.

Suppose a category sells 700 units over seven days.

The spreadsheet can divide that number beautifully.

One hundred per day.

Consumers are less cooperative.

They might buy:

42 on Monday.

38 on Tuesday.

54 on Wednesday.

61 on Thursday.

83 on Friday.

310 on Saturday.

112 on Sunday.

The weekly average is correct.

It is also commercially misleading.

Nobody bought the average day.

Demand arrived in a pattern.

Weather-sensitive retail is particularly prone to this problem.

Research involving hundreds of brick-and-mortar stores has found that daily weather can materially influence retail sales and that the magnitude and direction of those effects depend on both location and the merchandise being sold.

That should not surprise anyone in horticulture.

But there is a difference between knowing weather matters and building a business that behaves as though weather matters.

Spring Is an Event, Not a Date

Consider the first genuinely beautiful spring weekend.

People sometimes behave as though something has started.

You can see it across categories.

Garden centres become busy.

Patio furniture becomes relevant.

Barbecues move.

Home-improvement projects emerge.

People wash cars.

Bicycles appear.

Outdoor restaurants fill.

There is an interesting behavioural concept behind some of this.

Researchers Hengchen Dai, Katherine Milkman and Jason Riis studied what they called the fresh start effect.

They found that people become more likely to pursue aspirational behaviours following temporal landmarks.

The beginning of a week.

A month.

A year.

A semester.

A birthday.

A holiday.

These landmarks psychologically separate one period of life from another.

They create a feeling of:

That was then.

This is now.

Gardening has its own temporal landmarks.

They are not always printed on calendars.

The first real spring weekend may be one.

Opening the cottage may be another.

Putting the patio furniture outside can be one.

The first trip to the garden centre can itself become one.

There was life before gardening season.

Now gardening season has begun.

The First Warm Weekend Is a Permission Slip

This helps explain a familiar retail phenomenon.

Consumers can postpone outdoor projects for weeks without feeling particularly uncomfortable about it.

Then suddenly the entire neighbourhood seems to move outdoors.

The weather has provided social permission.

Now is the time.

The consumer no longer has to ask:

Is it too early?

Is spring really here?

Should I bother yet?

Everyone else appears to have answered the question.

That matters because human behaviour is influenced not only by physical conditions but by social context.

A neighbour digging a garden bed is information.

Cars at the garden-centre entrance are information.

People carrying plants are information.

Suddenly gardening is not something people will do later.

It is what people are doing now.

Retail momentum begins feeding itself.

Weather Can Change More Than Demand Volume

Recent consumer research suggests the effect of weather may be subtler than simply increasing or decreasing spending.

A 2026 study examining retail transactions and consumer responses found evidence that sunny conditions increased variety-seeking compared with cloudy conditions, while rainy conditions reduced it.

Temperature also had a non-linear relationship with variety-seeking.

That research involved another product category, so horticultural retailers should not simply assume identical behaviour for plants.

But it raises an interesting possibility.

Weather may influence not only whether people shop, but how they shop.

That would be particularly relevant to horticulture.

Consider the difference between a functional gardening trip and an exploratory one.

Functional:

I need two shrubs to replace dead ones.

Exploratory:

What could I do with the backyard?

The second trip potentially contains far more commercial possibility.

Sunshine may not simply activate a pre-existing shopping list.

It may broaden the imagination.

That is something worth understanding.

The Customer Is Shopping for a Future Self

Plants are unusual products because much of their value lies in the future.

A customer buying a television can turn it on tonight.

A gardener buying a young blueberry plant may be purchasing fruit that does not yet exist.

A peony may take time to establish.

A clematis is partly a promise about what will eventually cover the trellis.

The consumer is therefore making a purchase for a future version of themselves.

They are imagining:

future weekends

future flowers

future fruit

future shade

future colour

future enjoyment

Current conditions affect how vivid that future feels.

This is one reason warm spring weather is commercially powerful.

It shortens the psychological distance between the customer and that future garden.

The shopper can almost see it.

There Are Really Two Seasons

For horticultural businesses, we might think about spring in two different ways.

There is the production spring.

This is governed by crop schedules, plant development, shipping windows, frost considerations and logistics.

Then there is the consumer spring.

This is governed by weather, rituals, weekends, projects, social cues and perceived readiness.

These two springs are related.

They are not identical.

And much of the economic risk in seasonal horticulture occurs when businesses assume that they are.

A crop can be commercially ready before the customer is psychologically ready.

Equally, demand can activate faster than the supply chain expects.

The challenge is not to choose one clock over the other.

It is to understand both.

Canada Does Not Have One Spring

This becomes especially important in a national horticultural market.

Spring in Victoria is not spring in Edmonton.

Edmonton is not Winnipeg.

Winnipeg is not Toronto.

Toronto is not Moncton.

Even markets within the same province can behave differently.

Elevation matters.

Snow cover matters.

Temperature matters.

Urban microclimates matter.

Local habits matter.

Holiday timing matters.

And weather anomalies matter.

A national retailer therefore faces an uncomfortable reality.

The corporate calendar may contain one Week 16.

The consumer experiences dozens of different Week 16s.

In one region, shoppers may already be fully engaged in gardening.

In another, snow remains on the ground.

A standardized national program can therefore be operationally elegant and behaviourally clumsy.

Regional demand does not care how tidy the spreadsheet looks.

Historical Sales Are Useful, But History Needs Weather

A retailer examining last year’s sales might conclude:

This category becomes important in Week 18.

Perhaps.

But what happened in Week 18?

Was it sunny?

Was it unusually warm?

Was Easter early?

Was the previous weekend terrible?

Had pent-up demand accumulated?

Was there a frost?

Was the long-range forecast encouraging?

Calendar history without weather history can confuse correlation with cause.

This is becoming increasingly important because sophisticated forecasting systems can now incorporate weather variables directly.

A 2024 study using data from a large Canadian retail organization tested whether weather information could improve sales forecasting.

It did.

Models incorporating weather variables explained substantial additional variation beyond the baseline forecasts, at both individual-product and category levels.

That should interest horticultural retailers enormously.

Weather is no longer simply something the nursery manager looks at through the window.

It can become data.

Stop Treating Weather as an Excuse

There is a phrase heard constantly in seasonal businesses:

Sales were down because of the weather.

Sometimes that is completely true.

But it is not very useful.

Weather should not merely explain last week’s results.

It should help inform next week’s decisions.

The more interesting questions are:

What types of weather activate this category?

How quickly does demand respond?

Does today’s temperature matter, or the forecast for the weekend?

How important is sunshine compared with temperature?

Does several poor weekends create pent-up demand?

Do consumers respond differently early and late in the season?

How much does the effect vary by region?

How quickly can replenishment respond?

Which categories are most weather-sensitive?

These questions turn weather from an explanation into an operating variable.

That is a very different mindset.

Forecasts May Matter Almost as Much as Conditions

Consumers do not experience weather only by walking outside.

They check apps.

They watch forecasts.

They plan weekends.

They receive alerts.

A sunny Saturday forecast can influence behaviour before Saturday arrives.

That means horticultural demand may be partly anticipatory.

Someone sees that the weekend will be warm and begins thinking:

Saturday, I’ll work in the yard.

Once that thought exists, plant purchasing may become part of the plan.

This creates an interesting marketing opportunity.

The most valuable time to communicate with the customer may not always be during the perfect weather.

It may be shortly before it.

When the forecast creates intention.

Retail timing therefore becomes less about reacting to sunshine and more about anticipating the moment sunshine becomes psychologically relevant.

The Weather Window Has a Front Edge

Retailers understandably fear missing peak demand.

But perhaps we should think more carefully about the period immediately before it.

If marketing begins only after the parking lot fills, marketing is following demand.

The more interesting opportunity is to meet demand just as it awakens.

Suppose the weekend forecast changes on Wednesday.

Four warm sunny days are coming.

That information begins altering consumer plans before the first warm day arrives.

A retailer capable of responding quickly can begin communicating:

The weekend is coming.

Your garden is ready.

This is the moment.

The objective is not to manufacture demand from nothing.

The weather may already be doing that.

The retailer’s job is to catch the demand while it is becoming active.

Seasonal Marketing Should Behave Like Weather

Traditional marketing calendars are often fixed months in advance.

Email Wednesday.

Promotion Friday.

Campaign Week 17.

There are good operational reasons for that.

But horticultural demand is not entirely fixed.

A more responsive approach might contain two layers.

One is planned.

Seasonal campaigns.

Product introductions.

Holiday programs.

Scheduled advertising.

The other is reactive.

Weather-triggered messages.

Regional communications.

Rapid digital promotions.

Category emphasis based on forecast conditions.

The second layer acknowledges something fundamental:

Sometimes the consumer changes faster than the marketing calendar.

Modern digital marketing makes that flexibility possible in a way traditional print advertising never could.

The email can change.

The homepage can change.

Social content can change.

Regional messaging can change.

The weather changed this morning.

Marketing does not necessarily have to wait until next month.

Not Every Sunny Day Is Equal

There is another complication.

An 18-degree Saturday in April may have greater psychological power than an 18-degree Saturday in July.

Why?

Because the April day represents transition.

It is news.

It announces something.

The July day is normal.

This means retailers should not think only about absolute weather.

They should think about weather relative to expectation.

The first warm day after a cold spell can feel extraordinary.

The same temperature after two warm weeks feels ordinary.

Likewise, several rainy weekends can create accumulated gardening intent.

When the weather finally changes, demand may arrive with unusual force.

This is why simple temperature thresholds do not tell the whole story.

Humans respond to contrast.

Seasonal momentum matters.

The First Beautiful Day May Be Worth More Than the Tenth

Imagine ten consecutive warm spring days.

The first may activate dormant projects.

The second reinforces them.

By the tenth, much of the most urgent demand may already have been released.

This suggests horticultural demand may have something resembling diminishing psychological novelty.

Again, the weather itself is not the only thing changing.

Consumer state is changing too.

The gardener who had been waiting to plant finally planted.

The patio containers were purchased.

The Mother’s Day gift was bought.

The shrubs were replaced.

Some demand has now been satisfied.

The same temperature therefore enters a different market.

That is why the relationship between weather and sales is unlikely to be perfectly linear.

Consumer history matters.

Peak Season Is Really a Series of Triggers

Retailers often speak about “the spring rush” as though it were one event.

It may be more useful to think of several overlapping activation points.

The first warm weekend.

Easter.

Mother’s Day.

The first frost-free expectation.

May long weekend.

Opening the cottage.

Graduation parties.

Backyard entertaining.

Planting vegetable gardens.

Each event awakens different customer motivations.

One shopper is preparing the front entrance.

Another is buying a Mother’s Day gift.

Another is opening the cottage.

Another has decided this is finally the weekend to plant fruit.

The horticultural season is therefore not simply one wave.

It is a sequence of behavioural waves.

Retailers who understand which wave is approaching can make better decisions about what to emphasize.

Timing Is Part of Marketing

Marketers traditionally think about four familiar variables.

Product.

Price.

Place.

Promotion.

Seasonal categories suggest another deserves equal attention.

When.

The same product.

At the same price.

In the same store.

With the same presentation.

Can produce dramatically different consumer responses depending on when it is offered.

A hydrangea has not changed because the sun came out.

But its relevance may have.

This makes timing part of the value proposition.

In horticulture, the product and the moment interact.

The consumer is not merely buying a plant.

They are buying a plant while gardening feels important.

The Nursery Manager Knows Something the Algorithm Doesn’t

There is enormous value in better forecasting.

Weather data.

Historical transactions.

Category patterns.

Regional models.

Machine learning.

All of it can improve planning.

But local knowledge still matters.

A good nursery manager knows when the parking lot feels different.

They recognize the first weekend customers arrive with real intent.

They know whether an unusually warm March day is enough to trigger gardening locally or whether customers remain cautious because everyone expects another snowfall.

They hear the questions.

They see what is being loaded into carts.

They notice when browsing turns into buying.

That information should not compete with analytics.

It should complement it.

The most sophisticated retail organizations increasingly combine structured data with human observation.

Horticulture should do the same.

Timing Should Be Managed, Not Merely Experienced

Before a spring season, retailers might ask:

• Which categories respond most strongly to weather?
• Which weather variables matter in our market?
• What happened during last year’s major sales spikes?
• Were those spikes connected to temperature, sunshine, holidays or accumulated demand?
• Which regions historically activate first?
• How quickly can inventory respond when forecasts change?
• Can marketing react regionally rather than nationally?
• Which messages should be prepared in advance for the first strong spring forecast?
• What local knowledge can store teams add to corporate forecasting?
• How will we recognize that latent demand has become active demand?

These are sales and marketing questions.

Not meteorological ones.

The weather is simply one of the inputs shaping consumer behaviour.

The Product Did Not Change

Return to that customer on Saturday morning.

Yesterday, they drove past the garden centre.

Today, they turn in.

Yesterday, the patio was something they would deal with eventually.

Today, it seems unfinished.

Yesterday, the blueberry plant was a product.

Today, it is summer fruit.

Yesterday, the rose was inventory.

Today, it belongs beside the front steps.

Nothing about the merchandise necessarily changed overnight.

The consumer did.

That is the strange economics of spring.

Horticultural companies spend enormous amounts of time making sure the right plants are available.

We should.

But availability alone does not create demand.

Demand appears when the product intersects with a moment in which the customer can imagine using it.

Sometimes that moment is Mother’s Day.

Sometimes it is a long weekend.

Sometimes it is the first trip to the cottage.

And sometimes it is nothing more complicated than opening the back door on a warm Saturday morning and realizing:

It’s spring.

The best seasonal retailers do not merely know when spring appears on the calendar.

They learn to recognize when spring appears in the customer’s mind.

And they are ready when it does.
