Can you grow vegetables in a cardboard box?

In the era of supermarkets and wholesale clubs, growing your own food isn't a necessity for most Americans. But that doesn't mean it's not a good idea to try.

A household garden can be a great way to reduce your grocery bill and increase your intake of nutrient-dense foods. It can also be a good source of exercise and a hobby that gets you outside in the sunshine and fresh air more often. However, not everyone has a yard where they can grow a garden or much outdoor space at all where they live. You can plant things in containers, but that requires some upfront investment in planters.

Or does it? Gardener James Prigioni set out to see if an Amazon shipping box would hold up as a planter for potatoes. He took a basic single-walled Amazon box, lined it with dried leaves to help with moisture retention, added four to five inches of soil (his own homegrown soil he makes), added three dark red seed potatoes, covered them with more soil, added a fertilizer, then watered them.

He also planted a second, smaller Amazon box with two white seed potatoes, following the same steps.

Two weeks later, he had potato plants growing out of the soil. Ten days after that, the boxes were filled with lush plants.

Prigioni explained how to "hill" potato plants when they grow tall enough, which helps encourage more tuber growth and protect the growing potatoes from sunlight. Hilling also helps support the plants as they grow taller so they don't flop over. He also added some mulch to help keep the plants cooler as the summer grew hotter.

After hilling, Prigioni only needed to keep up with watering. Both varieties of potatoes flowered, which let him know the tubers were forming. The red potato leaves developed some pest issues, but not bad enough to need intervention, while the white potato plants were unaffected. "It goes to show how variety selection can make a big difference in the garden," he explained.

The visible plants have to start dying before you harvest potatoes, and Prigioni checked in with the boxes themselves when they got to that point.

"I am pleasantly surprised with how well the boxes held up," he said, especially for being single-walled boxes. The smaller box was completely intact, while the larger box had begun to split in one corner but not enough to affect the plants' growth. "This thing was completely free to grow in, so you can't beat that," he pointed out.

Prigioni predicted that the red potatoes grown in the larger box would be more productive. As he cut open the box and pulled potatoes from the larger box, they just kept coming, ultimately yielding several dozen potatoes of various sizes. The smaller box did have a smaller yield, but still impressive just from two potatoes planted in an Amazon box.

People often think they don't have room to grow their own food, which is why Prigioni put these potato boxes on his patio. "A lot of people have an area like this," he said.

"I will never look at cardboard boxes the same," Prigioni added. "There are so many uses for them in the garden and it's just a great free resource we have around, especially if you're ordering stuff from Amazon all the time."

People loved watching Prigioni's experiment and shared their own joy—and success—in growing potatoes in a similar fashion:

"I have been growing potatoes in every box I can find for several years now. I have had excellent success. I honestly think potatoes prefer cardboard. And yes, most of my boxes were from Amazon."

"I live in an upstairs apartment with a little deck and I have a container garden with containers on every single stair leading to the deck. I grow potatoes in a laundry basket. It's amazing how much food I can get from this type of garden!! Grateful."

"I literally got up and grabbed the empty boxes by our front door, the potatoes that have started to sprout, and soil i had inside and started my planting at 1am. Lol. I will take them outside today and finish. Thank you James!"

"I grew potatoes and tomatoes on my tiny balcony in Germany (in buckets and cardboard boxes). Now I have a big garden here in America. I so love to grow my own food."

"I grew sweet potatoes in cardboard boxes. It’s so much fun."

Next time you're stuck with an Amazon box that you don't have a use for, consider whether you could use it as a planter for potatoes or some other edible harvest. Gardening doesn't have to be fancy to be effective.

Americans see gardening changes as 'plant hardiness zones' shift across half the U.S.

Here's a quick tool to find out if your zone has changed due to warmer temperatures.

The USDA has issued a new Plant Hardiness Zone Map

Millions of American households have a garden of some sort, whether they grow vegetables, fruits, flowers, or other plants. Gardening has always been a popular hobby, but more Americans turned to tending plants during the height of the COVID-19 pandemic for both stress relief and to grow their own food so they could make less trips to the store. For many people, it's a seasonal ritual that's therapeutic and rewarding.

But a shift is occurring in the gardening world. Now, due to rising temperature data, half the country find themselves in a different "plant hardiness zone"—the zones that indicate what plants work well in an area and when to plant them. Gardeners rely on knowing their hardiness zone to determine what to plant and when, but they haven't been updated since 2012.

The U.S. Department of Agriculture updated its Plant Hardiness Zone Map in late 2023, months before people in most of the country start planning their planting. We saw the 10 hottest summers ever recorded in 174 years of climate data between 2014 and 2023, but hardiness zones are actually determined by the coldest winter temperatures each year. Winters are warming at an even faster pace than summers, according to nonpartisan research and communications group Climate Central, but that may or may not be the entire reason behind the zone changes.

The USDA acknowledges that some of the zone shifts could be due to climate change but cautions against using them as hard evidence for it since factors such as improved data collection also contribute to changes in the map.

"Temperature updates to plant hardiness zones are not necessarily reflective of global climate change because of the highly variable nature of the extreme minimum temperature of the year, as well as the use of increasingly sophisticated mapping methods and the inclusion of data from more weather stations," the USDA wrote in November 2023. "Consequently, map developers involved in the project cautioned against attributing temperature updates made to some zones as reliable and accurate indicators of global climate change (which is usually based on trends in overall average temperatures recorded over long time periods)."

At the same time, Chris Daly, director of the PRISM Climate Group at Oregon State University who developed the map with the USDA, told NPR, "Over the long run, we will expect to see a slow shifting northward of zones as climate change takes hold."

As an example of zone shifting, Dallas, Texas, was classified as Zone 8a in 2012, when data showed the coldest winter temperature in the city was between 10 and 15 degrees Fahrenheit on average. In 2023, with data showing the coldest winter temps falling between 15 and 20 degrees Fahrenheit, it's been shifted to Zone 8b.

Some zone shifts resulted in moving to an entirely new zone number, such as Seattle shifting from Zone 8b to Zone 9a. The overall trend was for zones to be pushed northward, but not all areas saw a shift. NPR has a helpful tool here in which you can enter your zip code, see what zone your city was previously in, what zone it's in now, and the temperature changes that caused the shift.

The bottom line is if you have a gardening book with a hardiness zones map printed before 2024, it's time for an updated map, or check online to see what zone you fall in now to give your garden the best chance of thriving this year.

Andrew Millison's yard went from average lawn to abundant garden.

Fifteen years ago, Andrew Millison's yard looked like most average suburban American yards with a row rose bushes, a few trees, and a basic green lawn that had to be mowed and watered—good for running around and picnicking on, but not much else.

Today, it couldn't be more different or more productive. Where there used to be grass, now there's a "multi-layered permaculture food forest" that serves both Millison's family and their neighbors. In a video tour of his property in Oregon's Willamette Valley, the permaculture expert shares the five strategies he used to design his edible landscape.

But first, what does permaculture mean?

Permaculture refers to sustainable agricultural and design practices that work with nature rather than against it. Permaculture practices include observing and learning from natural ecosystems and creating purposeful systems that emulate them.

For instance, huge fields filled with neat rows of all one kind of crop might make planting and harvesting more efficient, but nothing in nature actually grows that way on its own. Agriculture that goes against nature means having to work hard to keep away pests, manage water distribution carefully, etc. Permaculture aligns human action with the diversity, stability and resilience that make healthy landscapes productive and self-sustaining long-term.

Here are the five strategies Millison used to do that right in his own yard:

1. Create productive edges

Edges of yards and gardens are usually decorative, but Millison's yard edges are almost entirely made of trees and shrubs that produce fruit or other food. From cherries to blackberries to fennel to grapes and more, he created "a solid corridor of food" for him and his community to enjoy. He even has an apple tree that grew out of a crack in the sidewalk. As neighbors walk by, they can partake of the abundance.

His cherry tree is grafted with four different varieties so they ripen at different times throughout the season. He also has a fig tree that he planted in the south-facing part of the yard to take advantage of the increased heat reflected off the sidewalk.

2. Plant food everywhere

We're used to thinking of a gardens as a distinct part of a yard, not the whole thing, but why? Millison makes use of the land he has by planting food literally everywhere—front yard, side yard, back yard, all of it.

Millison has perennial plants like his artichokes, which means he doesn't have to replant them every year. He also has an annual garden patch, growing things like lettuce, zucchini, broccoli and more, which he harvests from every day during growing season.

3. Diversity of plants

Hyperdiversity is an important strategy, says Millison. Flowers and native plants are a big part of the food-bearing ecosystem, not only attracting pollinators but also supporting insect predator and prey relationships, keeping pests at bay in the garden.

"So I not only have the cultivated ecosystem of exotic food and flowering plants, but I have the ecological matrix of a native, intact system as well," says Millison.

Along with the diversity of flowers, Millison also keeps bee hives. The bees pollinate the garden and provide honey (which he puts in his tea he makes with the overabundance of fresh mint he has growing). And because their range is about a mile, the bees from Millison's hives help pollinate his neighbor's gardens as well.

4. Chicken rotation system

Bees aren't the only animal Millison tends to in his permaculture garden. His chickens also play a big role in fertilization, weeding and tilling of the soil, thanks to a rotation system he uses season to season. During the summer, they stay in a paddock where their activity prepares the soil for a winter crop that will be planted there. After the harvest in the fall, they move to the main garden area where they do the same thing, preparing the soil for the next summer's planting.

"Having the chickens move back and forth between these gardens creates a wonderful synergy where the chickens take care of a lot of the important garden work so I don't need to do it," he says.

The chickens have a coop that can be accessed from either area and which is also connected to the greenhouse, which is part of Millison's final strategy.

5. Create microclimates

Millison's small lot has about 50 trees planted on it, but it's designed as a "solar bowl" so that all of the plants get the amount of sunlight they need.

A microclimate element familiar to most of us is the greenhouse, and Millison's greenhouse is made from mostly recycled materials. It stays much warmer than the outside, enabling him to keep citrus trees, desert foliage and other plants that don't do well with prolonged below-freezing temperatures. (His greenhouse even has a jade plant from a cutting he got from Jerry Garcia(of The Grateful Dead.)

In an example of the whole permaculture design working together, the chickens' nesting boxes in their coop are attached to and open up into the greenhouse for easy collection.

"You know, your quality of life really goes up when you surround yourself with gardens, with nature," says Millison. "I find my peace in going out here and gardening. It's my hobby. I have a lot of creative energy out here as well. It's a wholesome feeling and it's a secure feeling."

Millison says the garden does help with their grocery bill and there's nothing like eating something fresh that literally just been picked. But it's also about sharing, he says.

"I've got a school down the block. The kids are always walking by, they're eating all the berries and fruits on the sidewalk. I've got neighbors coming over—I'm always sharing my surplus. It's a really good way to build community with your neighbors."

Imagine if everyone's yards were used to grow food this way. You can learn more about Millison's expertise and other permaculture projects around the world on his YouTube channel as well as his website at andrewmillison.com.

People share things they imagined they’d never do but now totally love

Proof that we shouldn’t limit ourselves with “never.”

person showing green plant

Most of us have things we're willing to try and other things we swear we'll never do. Some of those "nevers" are actually smart boundaries—definitely shouldn't knock "never" entirely—but some things we unnecessarily omit from the list of possibilities simply because we think they aren't for us or that we won't actually enjoy them.

However, "never say never" is a saying for a reason. How many of us thought we'd never like a food that we've actually grown to love? How many hidden talents or interests have we discovered by trying something we assumed wasn't our thing?

Someone on Reddit asked, "What’s something you thought you’d never do that you found out is actually really enjoyable?" and people's responses are surprisingly inspiring. If you've ever thought any of these things wouldn't be up your alley, take a look at what others say about their experiences. Maybe it really isn't for you, but maybe—just maybe—you'll discover a new love when you start letting go of some "nevers."


Being a workout person

"Going to the gym regularly - hated it at first, but now it’s my therapy."

"One of my few discoveries too. Staying active and working out really does clear your head and also pumps me up enough to have energy throughout the day."

"Yes!! I go to a hard-core class 4x a week now and I feel better!"

"I hated it at first as I felt lost in regards to exercise selection and hate eating (eating in a calorie surplus is necessary for building muscle) but once I noticed I was no longer the skinniest guy in the room and had a decent (not huge) amount of muscle I kept at it."

"I never thought I'd say this, but going to the gym has actually become something I really enjoy! I was trying to lose weight last year and I met a really nice trainer who taught me a lot of tips. And now I lost 20 pounds, have a healthier body, and strength training even makes my nasolabial folds lighter."

"Weightlifting, who knew taking out my anger on some heavy barbells would make me feel EXCELLENT, keep my weight low, make me strong looking, and give me a place and activity to hang with my friends that wasn’t a bar?"

Gardening

"Gardening. I was raised a city kid. Rented a house for a bit in a neighborhood where people took real pride in their yards, so out of respect, I tried to spruce the yard up a bit with plants.

Very little in life has such solace and reward. Not everything you plant works out, but it's peaceful digging the hole and putting it in the ground and months later, if it lives and blooms, you know you did that. You made that happen. And every spring that flower will return and brighten your day and you know that you put it there and it lived."

"This for me as well. I love spending hours pottering around my garden and spending a fortune growing food that mostly gets eaten by the critters. Massively beneficial for my mental health."

"This is my 2nd year having a small veggie garden, and last year I struggled a lot. Most things died besides my green beans and my cayenne peppers. This year has been so much better. My pride and joy is my Scotch Bonnet plant that I grew from seeds that I almost killed and thought for sure wasn't going to make it. It's thriving and I just harvested a bunch of peppers. It's very rewarding to me."

"I hated it too until I finally realized - I don’t hate gardening, I hate being dirty. I got proper gloves and waterproof clogs and I’ve transformed my yard into a paradise."

"I thought gardening was just for retirees and super serious people. Turns out, digging in the dirt while talking to plants is surprisingly therapeutic and makes you feel like a horticultural wizard with magical plant-growing powers!"

Giving up alcohol or other addictions

"Give up drinking. It wasn’t easy, but damn are my weeks, nights and days better without alcohol."

"Amen. I needed rehab but I’m 7 months and 1 day sober. Never thought I’d quit, figured it would kill me someday. February 8th this year I decided I was done and needed help. I asked for it and I got it. Life is so much better. Even the bad days are handled so much more constructively. Best thing (and scariest) I’ve ever done."

""Never thought I’d quit, figured it would kill me someday." yeah man i'm just shy of 4 months, I feel that IN MY BONES. its funny how bad things that would have been the end of the world earlier are now just inconveniences."

"This 100% I'm going on 4 months now after drinking nearly every day for the last 14 years. It's like I was asleep all that time. Life is completely different for the better."

"Keep going my man! Addiction is a curse. I had the same problem with weed. Since I stopped, my life took a U turn."

Hiking and kayaking

"Hiking/walking trails. It was terrible the first few times I did it and had terrible soreness in my feet days after. Now, I can do 6 miles a day with virtually no pain."

"I used to hate hiking because I always thought it was just "Walking but with added challenge". Then I started going on more hikes in places I had never been before and I understood. It's not about getting to somewhere specific, it's about enjoying the walk itself!"

"Going hiking! I thought it’d be boring, but it’s actually so refreshing and fun. Totally changed my view!"

"Yes! I thought I was too weak and delicate to go hiking, but one year later, I hiked up a mountain! It's a daily view on my commute, and I can't help but smile whenever I see it."

"Kayaking. Being that far from civilization is the closest I’ve ever felt to free and at peace:)"

"Kayaking is really soothing and fun!"

"My wife and I just started kayaking last summer, and it allows me to clear my mind and paddle. I am far far from being fit, but I've learned that it's both relaxing and a great workout."

Miscellaneous honorable mentions

"I’ve recently picked up cooking and painting. Didn’t think I was talented enough to paint but it turns out I can- I just paint abstract things"

"Public speaking. I used to hate it, but now I find it exhilarating!"

"Meditating. I was convinced I could not shut off my brain (it's still a challenge). But just sitting quietly with my thoughts for 10 or 15 minutes really does remind me that whatever's weighing heavily on my mind really isn't that big of a deal in the grand scheme of things."

"Being openly honest about my feelings, insecurities, faults, etc, in somewhat of a humorous, self deprecating way. I found out that when you’re open about those things that others will almost immediately start agreeing and opening up themselves about the same issues. I learned that I’m not nearly as alone as I thought I was, and most of those feelings are pretty common among other people. It’s quite liberating!"

"Basket weaving! I was at a medieval market and some guy sat there doing a presentation of it and letting people have a go. I tried it too and enjoyed it greatly! The repetitiveness of the work really lets you unwind and relax your mind."

"Driving a school bus for a living. I swore it was the one job I'd never do. Now I'm 5 years in and, as far as jobs go, I find it extremely rewarding and pretty fun."

All of these answers show that you just never know. Maybe one of your "nevers" will become a beloved activity if you give it a try.
