If you’ve grabbed a salad or made tacos at home lately, you might have noticed something missing at the grocery store — or at least a much higher price for a head of lettuce. The lettuce shortage in the U.S. has become a real headache for restaurants, shoppers, and even growers themselves. It’s not just a blip or a single bad harvest. There’s a mix of factors coming together, and they’re pretty tough to untangle.
Why Lettuce Matters So Much
Lettuce isn’t some niche vegetable. In the U.S., it’s a refrigerated aisle staple. From burgers and sandwiches to Caesar salads and DIY taco nights, lettuce is in everything. We’re talking about a multi-billion dollar crop. California’s Salinas Valley alone grows more than half the country’s supply. So when something goes wrong there, everyone from grocers to fast-food chains feels it almost right away.
What’s Behind the Shortage?
There isn’t just one reason lettuce has become scarce lately. Instead, it’s a tangle of bad luck, bad timing, and some challenges that are getting worse with time.
Disease is Wiping Out Crops
The biggest culprit right now is a plant disease called Impatiens necrotic spot virus, or INSV for short. INSV isn’t a disease you’d know by name unless you’re an ag expert, but it’s been ruining lettuce harvests for a few years now. The virus is spread by super-tiny insects called thrips. And it’s been especially bad in Salinas Valley, which is the main growing hub.
If the virus hits a lettuce field, a whole lot of the crop is done for. There are rules around destroying infected lettuce, so growers sometimes have to plow whole fields under. It’s even worse for organic farms. They can’t use many of the chemical pesticides that slow the problem down, so there’s even less organic lettuce out there.
The Weather Isn’t Helping
Then, there’s the weather. If you picture California and Arizona, you might think of sunny skies year-round. But key lettuce-growing regions like the Imperial Valley (California) and Yuma (Arizona) had a run of cold weather. That meant the lettuce grew slower or not at all, and harvests were pushed back.
Freezing nights and big temperature swings mess with lettuce growth, too. When those line up with disease outbreaks, you end up with fields that look fine one week and half-empty the next.
Pests Pile On
The problems don’t stop with disease and weird weather. Regular pests — not just thrips, but aphids and other bugs — have stuck around in bigger numbers than usual. In transition months when fields switch from one region to another, pest pressure tends to go up. That’s exactly when the lettuce shortage got even tighter this year.
Supply Chain is Stretched
On top of disease, pests, and weather, there’s a supply chain issue. During the pandemic, more people stayed home and cooked meals themselves. Suddenly, instead of lettuce going mostly to restaurants, demand at grocery stores surged. And when farmer yields drop due to destroyed crops, the system can’t keep up. Mandatory crop destruction because of disease, paired with low yields, created a real squeeze. Everything got more expensive.
Lettuce Prices Are Up and Shelves Are Empty
The price jump is the part most of us notice first. Since the supply dropped off so sharply, the cost of lettuce rose fast, too. In February 2025, some wholesale prices were up to $30 or even $40 a box for certain types like iceberg and romaine. That might not sound wild until you remember those boxes usually sell for much less when times are good.
This has been especially rough for organic lettuce. Because INSV was so hard on organic farms, there’s been even less of it on store shelves. Some retailers just can’t get enough. If you’ve been skipping salads lately or noticing smaller sandwich toppings at your local café, now you know why.
The shortages have been especially bad during “transition periods” — those few weeks each year when farms switch from one growing region to another. Normally, produce managers can plan around those, but add in disease, cold snaps, and pests, and suddenly there are entire weeks where stores are out.
Restaurants and Shoppers Both Feel It
How does this play out for real people? Restaurants have been scrambling. Some are rewriting menus, cutting back on lettuce-heavy dishes, or just telling customers there’s no salad right now. The higher costs don’t just stop at the supplier level — sometimes you see them in a pricier sandwich or $2 upcharge for a Caesar salad.
For shoppers, it’s frustrating to weekend-shop and find slim pickings in produce. Other shoppers grab what they see and move on, but when lettuce is part of your plan, there’s just not a perfect substitute.
Why Hasn’t This Just “Fixed Itself?”
You might wonder: isn’t this just farming? Don’t crops bounce back when the weather improves? That’s usually true, but this time things are different. The lettuce supply isn’t as simple as flipping a switch.
In the U.S., lettuce growing shifts from region to region multiple times a year. The Salinas Valley handles spring and summer, while Arizona and California’s desert farms carry things through the winter. There are always short “gaps” between seasons, but this time those gaps turned into real shortages. The pressure from disease and weather pushed down yields across both regions, so the usual seasonal handoff didn’t go smoothly.
Climate Change Isn’t Making Anything Easier
There’s a bigger story in the background: climate change is making all these problems tougher to solve. For example, experts are warning that rising temperatures and shifting weather patterns help insects like thrips spread more widely. That means INSV risk isn’t going away anytime soon — in fact, it could get worse.
At the same time, water supplies are an issue, especially in Arizona. That state depends on the Colorado River to keep lettuce fields irrigated. The last few years have seen cuts and restrictions due to drought, so future lettuce harvests might struggle even if the weather looks good.
A Peek Ahead: Will Lettuce Prices Settle Down?
Right now, most produce experts think things will get a little better. When the growing regions move back to Salinas for late spring and summer, we should get more lettuce on shelves. Usually, supply bounces back after that shift, but only if the fields avoid disease and pests.
Still, no one expects prices to crash back to normal overnight. Growers, shippers, and grocery chains all have to recover losses and plan for the next year. Ongoing risks — like new waves of INSV, surprise cold snaps, or more water shortages — could mean we’ll see more unpredictable lettuce prices going forward.

What Are Growers Doing About It?
So, what’s being tried to get the situation under control? For INSV, researchers are studying new disease-resistant lettuce varieties, but these won’t hit big farms right away. Some growers are experimenting with crop rotations to keep pests and diseases down. Others are exploring biological, not chemical, treatments — especially organic farmers, who need new ways to keep fields healthy without pesticides.
There are also efforts to use more efficient irrigation methods, so crops can thrive on less water. With river levels falling and sustainability debates heating up, you’ll probably see more stories on this front in the next few seasons.
The Bottom Line for Shoppers and Eaters
So yes, lettuce is pricier right now, and sometimes hard to find. It comes down to a mix of factors: viral plant disease, cold snaps, stubborn pests, supply chain slowdowns, and shifting demand. Each alone would hurt the market — together, they make a big dent.
Will lettuce shortage last forever? Probably not. Seasonal transitions tend to refill the pipeline, unless another weird weather event or fresh disease wave hits. But for now, it’s worth keeping in mind if you’re planning a salad-heavy party or wondering why your favorite lunch spot is charging a bit more.
Growers, scientists, and retailers are all watching for the next twist. In the meantime, we’ll all just have to keep an eye on the produce aisle and hope for a smoother growing season ahead.
