Modern Victory Garden: High Yielding Crops

We love growing and sharing fun, unique crops like Imperial Star Artichokes, Short-Toothed Mountain Mint, Mexican Sour Gherkins, and Cactus-Flowered Zinnias. But lately, we’ve gotten a lot of questions and comments from folks on Facebook wanting more information about staple crops or crops that could make up more bulk in a family’s diet.

Understandably, the memory of the Covid-19 pandemic, the rising cost of living, and people’s desire to control part of their own food supply is driving a renewed interest in seed saving, chicken keeping, and history-inspired “victory gardens.”

Whether you’re interested in lowering your grocery bill, keeping more of your diet organic, reducing your food miles, or improving your family and community’s self-reliance, here are some high yielding varieties to consider for your modern victory garden.

What Staple Crops Should I Grow?

There is no one-size fits all staple crop. What you should grow in your garden to maximize production will depend on your family’s tastes, your climate, and your garden’s size and soil conditions. What you plant also depends on the time of year.

Your family’s taste and what you will actually use should be one of the most important considerations. It’s likely that your family will maintain the ability to visit the grocery store, so if you plant a ton of butternut squash and no one enjoys it, it will probably go to waste. Similarly, you also want to be mindful of what you have the time to process. Cucumbers are highly productive, but if you don’t have time to pickle them, you’ll quickly end up with a lot of waste if you over-plant.

What grows well in your area will also play a huge role in determining what crops you should select to maximize production. If you’re new to gardening, it’s helpful to talk to neighbors or a local master gardener group for suggestions. A soil test is also a good idea before you plant.

Space is also a factor. If you just have a few raised beds, planting several successions of quick crops like summer squash, bush beans, and collards will provide a lot more food than waiting for a couple of winter squash plants to mature over a long season.

Think about what produce your family purchases most, and then look at this list and see what crops make sense in your garden.

Varieties to Maximize Production

There are hundreds of varieties to choose from, but these are a few of our favorites for their ease of growing, good production, and disease tolerance. They are divided into two categories: long-season crops, which you can generally only plant once in spring, and short-season crops, which are often ideal for succession planting and fall gardens.

Long Season Crops

Here are some of the long-season crops that are highly productive. Besides a long season, many of them also require ample space and may be better suited to large gardens.

Magic Cushaw Winter Squash

Magic Cushaw Winter Squash (110 days)

“We named it Magic Cushaw because it is so good and always pulls through, resistant to most everything, and now it is the only winter squash we grow,” writes grower Julia Asherman.

This unique squash produces an amazing mix of shapes and sizes, including round, oval, cheese-type pumpkins, and long-necked ones. Each fruit weighs about 5 to 30 pounds and stores well.

Beauregard Sweet Potatoes (100 days)

Beauregard is among the most popular sweet potato varieties in the United States, and for good reason. It’s reliable, highly productive, and disease-resistant. Beauregard has dense orange flesh that’s sweet, creamy, and nutty when boiled or baked.

Developed by Louisiana State University, Beauregard Sweet Potatoes are a great way to maximize your calories per acre in a home garden, particularly in the Southeast. They also keep well in storage.

*Growers in northern climates may have better production from traditional or “Irish” potato varieties.

Amish Paste Tomatoes (80 days)

Sometimes the classics are classics for a reason. Amish Paste tomatoes are the largest paste tomatoes we offer, and they have a robust flavor that matches their size! They’re ideal for canning and make an incredible sauce. They’re also juicy enough to use as a slicing tomato.

Amish Paste produces tall plants and heavy yields, so you’ll need a sturdy trellis to keep up with them. Use appropriate spacing and prune plants to improve air circulation and keep the plants healthy.

Tennessee Red Cob Dent Corn (120 days)

This heirloom corn dates back to before 1900 and is always high-yielding, producing up to 150 bushels per acre here in Virginia. Our original seedstock was supplied by Harold Jerrell, who reported that in 1995 this variety produced a good crop on only 2 inches of rain from mid-June until the first of September. It was one of the driest years on record in his growing area in Virginia and was the only variety that produced.

Tennessee Red Cob grows 10 to 13-foot sturdy stalks that you can use to support pole beans. Each stalk produces one or two 6 to 9 inch ears per stalk. This corn makes delicious cornbread and polenta.

*Growers in northern climates may have better luck with a flint variety like Floriani Red Flint, which is better suited to cool spring soil.

Iron and Clay Southern Peas (60-100 days)

Today, farmers often plant these vigorous, drought-hardy plants as nitrogen-fixing cover crops or grown for animal fodder. However, they’re also a tasty, highly productive staple crop.

Iron and Clay Peas came to this region through the forced migration of enslaved Africans and have long been grown as crops of survival and resilience. After the Civil War, Iron and Clay peas helped sustain newly freed Black communities, a history documented in George Washington Carver’s 1908 Cookbook of Field Pea Recipes.

You can enjoy the peas at several stages and use them as a short or long season crop. In about 60 days, you can harvest the peas as snap peas/green pods before the seeds swell in the pods. For green shell peas, harvest when the pods are filled but still plump and soft. In about 100 days, when the seeds turn brown and dry, you can harvest them for storage and winter use.

Short Season Crops

Here are some short-season crops that are highly productive. Many of these produce over a long season, are great for succession planting, or will grow as a fall crop. These are perfect for starting now if you still have space to fill in your garden.

Tromboncino Summer Squash (60 days)

This reliable Italian heirloom produces long fruits that curve to a bell at one end. When they’re young and light green, they make a tasty summer squash, but they also mature to tan with flavor much like a butternut. These dual-purpose, moschata type squashes bear all season in the south where others fail, thanks to their resistance to vine borers.

Tromboncino squash grow on long vines, which you can trellis for easy harvesting. For summer squash, harvest the fruits when they’re 8 to 10 inches long for tender flesh and sweet flavor. Allow them to mature full on the vine until they’re hard and tan for butternut-type squash and winter storage.Tiger Eye Bush Beans

Tiger Eye Bush Bean (55 to 80 days)

Tiger Eye Bush Beans are a productive crop that offers a lot of versatility. At around 55 days, harvest and enjoy them as snap beans or wait until the pods fill out and use the white beans as shelly beans. Finally, you can let them full mature and dry to their beautiful pattern.

At their mature dry bean stage, Tiger Eye beans have a similar flavor to pinto beans. They’re rich and deliciously creamy. While cooking, their skins melt away, perfect for refried beans.

Georgia Cabbage Collards (70 days)

Georgia Cabbage Collards are a standout from the Heirloom Collard Project. The seeds originally came from Bobby Prevatte, whose grandparents grew them near Lumberton, NC.

These plants are vigorous, high-yielding, and hardy to 20°F. Georgia Cabbage Collards produce semi-prostrate plants with a moderate tendency to head. The sweet and tender yellow-green leaves have a rich flavor some describe as nutty and cabbage-like.Straight Eight Cucumbers

Straight Eight Cucumbers (57 days)

Straight Eight Cucumbers were the All-American Selection winner in 1935, and they’re still highly dependable, productive, disease-resistant, and high-yielding today. They produce very uniform, deep green, 8-inch fruits about 2½ inches in diameter with an exceptional flavor.

While Straight Eights are a slicing cucumber, they also make excellent pickles if you pick them small. For canning, harvest them when they’re 4 to 5 inches long.

Early Flat Dutch Cabbage (85 days)

Early Flat Dutch is an old heirloom that dates to pre-1875 or possibly pre-1855. It’s one of our favorite, reliable varieties for the Southeast and Mid-Atlantic thanks to its incredible heat-resistance.

This cabbage produces large, flat heads weighing 6 to 10 pounds each. Early Flat Dutch is a great sauerkraut variety and the best variety for storage.

 

These are just a few of the great varieties you can use to produce a massive harvest. There are also many other high-yielding crops you could include in your garden, like pole beans, carrots, beets, turnips, rutabagas, or sorghum. You may need to experiment for a few seasons to find what works best for your taste, climate, and soil. Happy growing!

Success with Sweet Corn in Small Spaces

Fresh sweet corn is one of the joys of summer and growing it yourself makes it even more special! However, sweet corn’s soil, space, and pollination requirements can make it tricky to grow in a small garden. Thankfully, with a few tips, you can get a great sweet corn harvest even in a small space.

Amend Your Soil and Feed Your Corn

Sweet corn grows best when the soil pH is between 5.8 and 7.0, or is slightly acidic to neutral. In most of the Southeast, we typically have moderately acidic soils. Getting your soil tested and liming your garden if necessary can help with production.

Your corn will also perform best in well-drained soil that’s rich in organic matter. We like to add several inches of finished compost to the top of our beds before planting. While we often picture sweet corn as a crop for large fields, there’s no reason you can’t grow it in raised beds, which is one way to establish rich, well-draining soil quickly, no matter what you’re starting with.

Corn is a heavy feeder and benefits from another application of fertilizer, compost, or manure while it’s growing. When your plants reach about one foot in height, side-dress your sweet corn with compost, manure, or fertilizer. If you’re using a traditional or organic granular fertilizer, select one with a balanced N-P-K ratio or one that is high in nitrogen. Getting your soil tested will also help inform your selection so you know if your soil is low in phosphorus and potassium.

Do not use “Weed and Feed” products that contain fertilizer and weed killer; these will contaminate your soil and kill vegetable crops.

Plant in Blocks or Circles

Unlike most of our vegetable crops, which are insect-pollinated, corn is wind-pollinated. The wind carries pollen from the corn tassels to the silks of each ear of corn. Each silk corresponds to a kernel on that ear. If you’ve ever had ears of corn missing full kernels, it was likely a pollination issue. In order for each kernel of corn on an ear to fill out on an ear of corn, it must be pollinated.

Large farms plant long rows of corn, but they also have large enough fields to ensure good wind pollination. If you’re working with a small space and less corn, we recommend planting in blocks or even circles. Each block should be about five rows wide.

Water Consistently

Many of the flour, flint, and dent corn varieties we offer are highly drought tolerant, having bed bred for centuries to survive and thrive without modern irrigation. Sweet corn is only moderately drought-tolerant and requires about one to two inches of water per week, especially in hot climates, to produce nice, full ears.

As most of the Southeast is still in drought, watering your sweet corn is crucial for good production. To help reduce your corn’s water needs, use drip irrigation or soaker hoses, which water the soil directly to avoid evaporation loss. You can also avoid evaporation by watering in the early morning or evening. Irrigation on a timer is great for this. Mulching around the base of your corn once it’s a few inches tall can also help keep the soil cool and moist.

Hand Pollinate Your Sweet Corn

Along with planting in blocks, you can also use hand pollination to ensure you get a crop of full, sweet ears. To hand-pollinate your corn at home, watch for when the tassels have fully opened and the anthers start releasing pollen.

When pollen is being released, take scissors and cut off the entire tassel, trying not to knock all the pollen off onto the ground. Then rub that tassel across the silks of the ears of corn on nearby plants. You don’t need to cut every tassel; just do a few to ensure you’ve spread pollen to each ear of corn. Wind will help spread the remaining pollen around. It’s that simple!

Hand pollination is also a common method seed growers employ when isolating multiple sweet corn varieties without enough isolation distance. Besides hand-pollinating through the method above, they also remove and bag all the tassels before they begin releasing pollen to prevent any additional cross-pollination with nearby corn.

Choose a Fast-Growing Variety and Grow Multiple Successions

Another issue with growing sweet corn in small gardens is that it’s one and done. Unlike your cut and come again lettuce that will give you weeks of salad or cherry tomatoes you can pick until frost, each stalk will only grow one or two ears of corn.

Thankfully, most sweet corn varieties are pretty quick-growing. In most climates, it’s possible to get multiple successions. Sow your first 5 blocks in spring after your last chance of frost when the oak leaves are the size of squirrel ears. Then you can sow another 5 blocks two to three weeks later or when another early spring crop like peas or spinach is finished for the season.

Harvest and Use Your Sweet Corn

For first time growers, knowing when to harvest their ears can be confusing. However, there are a couple of telltale signs to watch for that indicate your corn is ready for harvest. About 18 to 24 days after your corn’s silks appear, they will be dry and brown on the ends, indicating they’re ready to pick. Ripe sweet corn will be in the milk stage, meaning if you peel back the husk a bit and burst a kernel with a thumbnail, a white, milky fluid will come out.

Sweet corn is best enjoyed as quickly as possible after harvest. When you pick the ears, they start converting sugars to starches. Depending on the variety, they may be good for one to seven days in your refrigerator; of course, we recommend enjoying them the day you pick them.

If you have extra sweet corn, you can blanch and freeze it on or off the ears. You can also blanch and dehydrate the kernels for soups and stews later in the year. Lastly, you can preserve sweet corn by pressure-canning it. Note that water bath canning isn’t safe for sweet corn.

Guide to Greenhouse Tomatoes

We’re seeing more and more gardeners and backyard farmers using hoop houses, high tunnels, and greenhouses for tomato production. They’re a great option for getting an extra-early harvest of tomatoes and other heat-loving crops. However, they also come with their own set of disadvantages, especially here in the hot, humid Southeast. For a great harvest of greenhouse tomatoes, consider these varieties and growing tips.Greenhouse Tomatoes Table

Best Varieties

You can grow any tomato in a hoop house, but some will perform better than others. An enclosed greenhouse or hoop house offers different climatic and pest conditions than out in the field. Here are some of our favorite greenhouse tomato varieties.

V, F, and N at the end of a variety name indicate known resistance to verticillium wilt, fusarium wilt, and nematodes, respectively. Check out our full Key to Tomato Disease Tolerance for other abbreviations.

Ventilate Your Greenhouse

High humidity allows fungal diseases to thrive. As the summer gets hot and humid, you need to ventilate your hoop house or greenhouse well to avoid disease. Where possible, roll up the hoop house sides. Use exhaust fans to regulate heat and humidity. Most fan options come with a thermostat that will open the shutter and turn the fan on automatically based on temperature.

Consider Growing Multiple Successions of Greenhouse Tomatoes

Many gardeners don’t consider tomatoes succession crops because healthy, indeterminate plants can produce until frost. Unfortunately, in hot, humid climates like the Southeast, tomatoes often succumb to diseases like blight before frost kills them. Even in other areas, the plant’s productivity may slow over time.

Sowing multiple successions of tomatoes can help ensure you have productive tomatoes throughout the season, whether you want them for fresh eating, the market, or canning.

Additionally, planting multiple successions allows you to grow different types of tomatoes. For example, you can plant Glacier early, followed by a succession of Atkinson. Glacier produces in just 58 days and is extra cold tolerant, while Atkinson, bred by the University of Alabama, excels in hot, humid conditions.A hoop house with tomatoes

Trellis and Prune Your Greenhouse Tomatoes

Tomatoes are large, vining plants. To make the most of your greenhouse or hoop house space, trellis and train the vines vertically.

Most commercial growers use a vertical string system. Many of these systems use twine that’s suspended on a roller or pulley so that you slowly lower the twine as the plant matures, allowing the pruned bottom of the tomato vine to rest on the ground while the tip continues to grow. Growers often refer to this as the lower and lean method.

However, in smaller hoop houses or makeshift greenhouses, you can trellis plants with traditional field methods like the Florida weave, stakes, or fencing panels.

Training vines on a trellis will be much easier if you prune the tomatoes. Pruning also allows for additional air circulation, and when done correctly, can improve yields by encouraging flowering and fruit set. However, you still need plenty of foliage to maintain the plant’s growth. Check out our pruning guide for full instructions.

Irrigation

Tomatoes need consistent moisture, and hot greenhouses can dry out quickly. Water your tomatoes deeply on a regular schedule, allowing the soil to slightly dry between waterings. Consider installing drip irrigation or soaker hoses in your greenhouse to minimize your watering efforts. You can also hand-water small greenhouses and hoop houses with a hose and nozzle. Water the base of the plant and avoid splashing water onto the leaves.Tomato flowers

Pollination

Pollination is necessary for tomatoes to set fruit. If you have a hoop house where you can open the doors and roll up the sides, you may have no problem with pollination. However, in a closed greenhouse or hoop house system, bees and other pollinators won’t have access to your tomato flowers. If you can’t let pollinators in, you’ll need to do the work yourself by using a small paintbrush or Q-Tip to transfer pollen between flowers.
