Some of the Best Vegetables to Grow in Times of Crisis

Potatoes — Potatoes can be stored for up to six months, offering a source of nutrition that doesn’t require refrigeration. They can also be canned, which extends their storage life to three to five years. Hoss recommends planting potatoes two to three weeks before your region’s last frost, in rows spaced 36 inches apart. You should incorporate compost into your soil before planting.

Their favorite varieties include Kennebec, a round white potato with creamy flesh and low- to medium starch, and Yukon gold, which has a buttery yellow flesh. Red Norland, which is a medium-sized rose-colored potato with dense flesh and low starch, is another favorite.

Importantly, potatoes love to be hilled, which means adding additional soil to the bed and molding it around the plants. You should hill the potatoes two or three times during the growing season. The idea is that, since potatoes are a part of the plant’s stem, not the root, the more “stem” you keep underground, the more potatoes will grow and the better your harvest will be.³

Potatoes, which are rich in fiber, vitamins B and C and minerals like potassium, are easy to grow in the early spring and take about 85 to 100 days to mature, depending on environmental conditions.

Once you harvest the potatoes, it’s important to store them properly — loosely (not in plastic) in a dark, dry spot at around 50 to 60 degrees F. While potatoes like a dark, cool environment, they should not be chilled, as they’re damaged by refrigeration.

Green beans — Green beans, which offer a rich source of vitamins A, C and K and manganese, fiber and folate, are another excellent, productive storage crop, which can be canned right along with potatoes, or fermented.

Green beans can also be blanched and frozen for up to a year. Hoss recommends the momentum bush bean variety,⁴ which they say is the most productive bush bean variety out there, with high yields, concentrated harvests and high tolerance to stress.

Beans should be planted in spring after the last frost has occurred, as germination typically occurs when soil temperatures are 65 degrees F or higher (with optimal germination temperature being 77 degrees F).

The seeds can be planted directly outdoors and can be planted every couple of weeks in the spring and early summer so you’ll have production throughout the entire growing season.

Plant them as early as possible in the spring, since the plants will drop blooms, or cease production, during hot summer temperatures. Bush beans can be harvested three or four times in the season, and can also be planted in double rows to save space and increase your harvest.

To do this, make two rows of beans spaced 6 inches apart, with the double rows spaced 3 feet apart.⁵

If you have access to drip irrigation or a soaker hose, you can use it to provide irrigation to both rows of beans at once. Beans can also be planted densely, with Hoss suggesting gardeners “stack the plants thick” to ensure you’ll have plenty of beans to eat in the cooler months if you can them.

Heirloom onions — Heirloom onions are a truly sustainable food source. Homesteaders in the past growing such onions would come out to the field and dig up onions as they needed them, then dig up the bulbs and store them as you would normal onions to be replanted the next year.

Not only do onions store really well, keeping for two months or more after harvest, depending on variety, but you have your own seed stock that you can reuse and share with your neighbors. Further, onions, which are rich in vitamin C, sulphuric compounds, flavonoids and other phytochemicals, are incredibly healthy.

Carrots — As with most homegrown vegetables, the taste of a store-bought carrot can’t compare to the flavor of a homegrown variety. Plus, carrots are another useful vegetable during hard times, as they can be stored in the refrigerator for two to three weeks or blanched and frozen for even longer storage.

Other options include canning and fermenting, making these a versatile vegetable for long-term usage.

Like green beans, carrots can be grown in double rows with irrigation in between. Plant rows 6 inches apart, skip 3 feet, then plant two more rows 6 inches apart. Hoss recommends seeding carrots in a thick band and not thinning them, so you’ll have a “dense forest of carrots” and get a lot of production out of a little bit of space.

When grown this way, your carrots may not all come out uniform in size — some will be smaller and some bigger — but they’ll taste great just the same. Carrots should be seeded directly outdoors, as they don’t transplant well, and do best when planted in cooler temperatures during the early spring or fall.

Carrots, which are rich in valuable beta carotene, require longer to germinate than most other crops, and you’ll need to keep the soil moist for at least seven days for germination to occur. A soil temperature of about 75 degrees F is optimal.

If you live in the South, you can grow two crops of carrots per year. Plant one in the fall, allowing the crop to overwinter so you can harvest in the spring. Since it’s not too hot yet, the carrots will hold well in the soil, allowing you to harvest them as you need them. You can then plant another crop in the early spring, which will be ready for a late spring/early summer harvest.

Winter squash — Winter squash, with its thick skin, is another excellent food for storage purposes. Though they’re called “winter” squash, they’re grown during the warm part of the year but can be stored without refrigeration for use during the winter. Generally, the sweeter the variety, the less time they can be stored.

Kabocha, a winter squash with a creamy flesh that’s useful for soups, can be stored for about three months while more common butternut and acorn squash will keep for six months. The sweet dumpling variety, which is one of the sweetest winter squashes, has an average storage time of 30 to 45 days.

Winter squash is a good source of vitamins K1, A, C and E, as well as B vitamins, calcium and magnesium. Storage time is important, as winter squash produce one harvest at the end of the growing season, giving you food to enjoy all winter long.

Okra — Okra is a warm-weather crop that produces pods measuring 2 to 3 inches long, which grow on a large, leafy and perennial plant with hibiscus-type flowers. High in fiber, okra also offers vitamin K, manganese, folate and vitamin C, as well as plentiful amounts of flavonoids and antioxidants.

It’s an important crisis-crop because it’s a high-producing crop with long-term production. The plants may start producing pods when they’re 1 to 2 feet tall and will continue producing, as the plants grow 5 to 6 feet tall.⁶ However, you can cut the tops off when it gets about 4 feet tall, and plant three succession plants per year.

Hoss recommends planting okra — especially the most productive jambalaya variety — in the spring and again in midsummer and early fall, as it will grow up until the first frost date. It’s important to rotate where you plant okra, coming back only on a three-year rotation, due to nematodes, which are tiny worms that act as plant parasites.

However, once planted, okra is a hearty and versatile food that can be frozen, canned or pickled. It’s a staple food source in the South, and though it prefers irrigation for the most abundant productivity, it is somewhat drought-resistant and will still grow well in very hot, drier conditions.
