When to Plant Potatoes for the Best Harvest!

Long-Term Storage: Keeping Your Harvest Fresh

Proper storage is essential to make the most of your potato crop. After harvest, I let the potatoes cure for about a week in a cool, dark, and well-ventilated area. This step toughens their skins, helping them last longer. Once cured, I store them in a basement, where the temperature stays cool and consistent. I’ve relied on these methods to keep my potatoes fresh for months, ensuring my family has a steady supply of food through the winter.

2. Corn: A Dual-Purpose Powerhouse for Survival Gardens

Corn is one of the most versatile crops you can grow in your survival garden. With 365 calories per pound, it’s both a hearty fresh vegetable and a fantastic base for making flour once dried. In my garden, I prioritize crops like corn because they serve multiple roles—fresh corn on the cob is delicious during harvest season, while dried kernels can be stored long-term and milled into flour for bread or tortillas. This dual-purpose nature makes it an invaluable addition to any self-reliant garden.

How to Plant Corn: Spacing, Pollination, and Drying for Storage

Growing corn takes a little planning to get it right, but the rewards are well worth it. I plant my corn in blocks rather than rows to ensure proper pollination since it’s wind-pollinated and needs close spacing to thrive. I space seeds about 10–12 inches apart and keep rows about 2–3 feet apart. Once the corn matures, drying it is simple: leave the ears on the stalk until the husks turn brown and dry, then bring them inside to finish drying in a cool, dry place. I store the dried kernels in airtight containers for grinding later, ensuring we always have a source of nutrient-dense flour ready for any recipe. Corn is one of my favorite crops, and it’s easy to see why—it’s reliable, versatile, and incredibly rewarding.

3. Beans: A Calorie-Packed and Easy-to-Grow Crop

Beans are a survival garden superstar, packing around 600 calories per pound along with a solid dose of protein. They’re an incredible staple for staying energized and nourished, especially during tough times. Whether I’m making hearty soups or storing them for the long haul, beans never fail to deliver. They’re easy to grow, adaptable to different recipes, and one of the most reliable crops in my garden. If you’re building a garden for self-reliance, beans absolutely deserve a spot on your list.

Pole vs. Bush Beans: Choosing the Right Type

One of the first decisions to make when growing beans is choosing between pole and bush varieties. Pole beans climb and save space, which is ideal if your garden is small or you want to maximize vertical growing. Bush beans, on the other hand, stay compact and are perfect for planting in rows or intercropping with other vegetables. I grow both for variety and practicality—pole beans keep producing all season, while bush beans provide a quicker harvest. Either way, both are packed with protein and calories, making them an invaluable survival crop.

Drying and Storing Beans for Long-Term Use

Drying beans is a straightforward process that turns them into a long-lasting, shelf-stable food source. Once the pods mature and dry on the plant, I harvest them and leave them in a cool, dry place for a few more days to ensure all moisture is gone. After that, I shell the beans and store them in airtight containers or vacuum-sealed bags to keep them fresh. These dried beans are a go-to ingredient in my pantry, ready to cook whenever I need them. Growing, drying, and storing beans is one of the easiest ways to secure a reliable food supply for the future!

Pest Resistance and How to Grow Beans With Ease

One of the things I appreciate most about beans is their natural resistance to pests. I’ve found that they don’t require a lot of intervention when it comes to keeping pests at bay. Beans naturally produce compounds that help deter many common garden pests, which means I don’t have to spend much time spraying or worrying about insects. They also fix nitrogen in the soil, which improves soil health and reduces the need for synthetic fertilizers. Growing beans is as simple as planting them in well-drained soil, keeping them watered, and ensuring they have enough sunlight. Whether you’re planting pole beans to climb trellises or bush beans in rows, you’ll find them to be a resilient and productive crop that provides both food and benefits for the garden.

4. Squash: A Calorie-Dense, Long-Storage Crop

Squash is one of my favorite survival crops because it’s not only calorie-dense, providing about 80 calories per cup, but it also stores well for months. Whether it’s winter squash or summer varieties, squash has been a staple in my garden, offering a hearty and versatile food source. During harvest season, I love making soups, roasting it, or adding it to stews. The best part is that, with proper care, squash can be stored for months, giving me access to fresh, calorie-rich food long after the growing season ends. It’s one of those crops that keeps giving back, both in terms of nutrition and long-term storage.

Curing and Storing Squash: Tips for Long-Term Success

To get the most out of your squash crop, curing is essential. After harvesting, I leave the squash in a warm, dry spot for about 10 days to cure. This process allows the skin to harden, which helps preserve the squash for long-term storage. Once cured, I move the squash to a cool, dry place with good ventilation, like a basement or even a cool closet. I make sure they’re not stacked directly on top of each other, allowing air to circulate around each squash. Properly cured and stored, squash can last for several months, making it a reliable and nutritious crop to have on hand year-round.

5. Sweet Potatoes: Nutrient-Packed and Calorie-Dense

Sweet potatoes are one of my absolute favorite crops to grow in my survival garden. They are packed with nutrients, offering about 400 calories per pound, and provide a rich source of vitamins and fiber. Beyond their impressive calorie content, sweet potatoes are incredibly versatile in the kitchen. I can roast them, mash them, or even use them in soups and stews. Whether you’re looking to fuel up for the day or store them for the long term, sweet potatoes provide essential calories and nutrients, making them a valuable crop for any survival garden.

Growing Sweet Potatoes in Warmer Climates

Sweet potatoes thrive in warm climates and need plenty of sunlight to produce those calorie-packed tubers. In my garden, I plant them after the last frost has passed and make sure the soil is well-drained and rich in organic matter. Sweet potatoes prefer temperatures between 70–80°F (21–27°C), so if you’re in a hotter climate, they’ll love it. I space the slips (young plants) about 12–18 inches apart, allowing them room to spread and grow. I also make sure they get consistent water, especially during dry spells, but avoid overwatering as this can cause the tubers to rot. Growing sweet potatoes in warmer climates is a rewarding experience, and with the right care, you’ll be harvesting plenty of these nutritious gems.

Curing and Storing Sweet Potatoes for Long-Term Storage

Once harvested, sweet potatoes need to be cured for about 10–14 days in a warm, humid place (around 80–85°F or 27–29°C). This step helps the skin toughen up and increases their sweetness. After curing, I store them in a cool, dry, and well-ventilated area, like a basement. Sweet potatoes can last for several months if stored properly, which makes them an excellent long-term food source. I’ve found that they store best when they aren’t stacked on top of each other, allowing airflow around each tuber. This simple process allows me to enjoy sweet potatoes well into the colder months, ensuring that my family has a nutritious, high-calorie food supply even in winter.

6. Wheat: High-Calorie and Ideal for Flour Production

Wheat is one of the most rewarding crops to grow in your survival garden, especially if you have the space and an interest in grinding your own flour. With around 1,400 calories per pound, wheat provides an incredible amount of energy in a small package, making it a staple for long-term food storage. The ability to grow and mill your own flour for bread, pancakes, and other baked goods is not only incredibly satisfying, but also an empowering step toward self-sufficiency. In my garden, I love knowing that with just a few simple steps, I can turn a handful of wheat into the foundation for many meals. If you’re looking to take your gardening to the next level, growing wheat is definitely worth considering!

Harvesting and Processing Small-Scale Wheat

Harvesting and processing wheat on a small scale may seem daunting, but with the right techniques, it’s totally manageable. I start by growing hard red winter wheat or soft spring wheat, both of which do well in my climate. When the wheat heads turn golden and the kernels feel firm to the touch, it’s time to harvest. I cut the wheat heads and let them dry in a cool, dry space until they’re ready to thresh. Threshing, or removing the grains from the stalks, can be done by hand or with a small machine if you prefer. After threshing, I winnow the wheat to separate the chaff from the kernels, leaving me with clean wheat ready to be ground into flour. While it’s a bit of work, processing wheat on a small scale is incredibly satisfying and provides you with an ongoing source of fresh, homemade flour!

7. Sunflowers: A Dual-Purpose Crop for Oil and Snacks

Sunflowers are a fantastic addition to any survival garden, and I love how they serve as a dual-purpose crop. With about 585 calories per pound, sunflowers not only provide delicious snacks through their seeds, but can also be used to produce oil. The seeds are nutrient-rich and make for a great snack on their own, or they can be roasted, added to salads, or sprinkled on top of baked goods. Plus, the oil extracted from sunflower seeds is a valuable resource for cooking, preserving, or even as an ingredient in homemade skincare products. This versatile plant makes it easy to grow two essential resources in one—fuel for the body and oil for various uses!

Harvesting and Pressing Sunflower Oil

Harvesting sunflowers for their oil starts when the petals begin to dry, and the seed heads turn a deep brown. I wait until the seeds are fully mature before cutting the heads and allowing them to dry further. Once harvested, I remove the seeds from the heads and clean them thoroughly to ensure there’s no debris. Pressing sunflower oil at home is a simple process using a manual or mechanical oil press. I place the cleaned seeds into the press, which extracts the oil by applying pressure. The resulting oil is pure and rich, and I store it in airtight containers away from heat and light to preserve its freshness. While it does require a bit of effort, producing your own sunflower oil ensures that you have a sustainable and nutritious cooking oil right from your garden.

Planning a Caloric Survival Garden

Small Garden Examples: Maximizing Space Efficiency

If you’re working with limited space, don’t worry—small garden layouts can still yield big results! I’ve found that using raised beds or vertical gardening techniques is a fantastic way to maximize every inch of space. For instance, I use vertical trellises to grow beans, cucumbers, and tomatoes, allowing the plants to climb and save ground space for other crops. In my small garden, I also practice intensive planting, where crops are spaced closely together to maximize yield without overcrowding.

Another layout that works well for me is the square-foot gardening method, where I divide the garden into small, manageable sections and plant a different crop in each square, based on its needs. With careful planning, you can make the most of even the smallest garden space and grow a variety of crops that will sustain you throughout the year.

Succession Planting: Maximizing Harvests in One Season

Succession planting is one of my favorite strategies to get multiple harvests from my garden in a single season. By planting crops at different times, I can ensure a continuous supply of fresh produce throughout the growing season. For example, I’ll start my garden with early spring crops like lettuce and spinach, then once those are harvested, I’ll plant a second crop like beans or beets in their place.

Similarly, after harvesting my first round of radishes, I’ll plant carrots or another crop in that same space to make sure the soil is never left bare. Succession planting helps me keep my garden productive, giving me the ability to enjoy a variety of crops and increase overall yields without expanding my space.

Preservation Tips: Canning, Drying, and Freezing

Once my garden starts producing, preserving the harvest becomes a priority. I rely on several methods to extend the shelf life of my crops, starting with canning. Canning is an excellent way to store fruits, vegetables, and even meats for long-term use. I especially love canning tomatoes, beans, and fruits for making jams or sauces.

Drying is another method I frequently use, particularly for herbs, beans, and even mushrooms. I use a food dehydrator or just hang herbs to air-dry in a warm, dry space. Lastly, freezing is perfect for preserving things like corn, peas, and berries, maintaining their flavor and texture for months. With these preservation techniques, I can enjoy my homegrown produce even when it’s out of season, keeping my pantry well-stocked all year long.

Common Challenges and Solutions

Pest Control Strategies for Calorie-Rich Crops

When growing calorie-rich crops like potatoes, beans, and squash, pest control becomes a crucial part of maintaining a healthy, productive garden. I’ve learned over the years that natural pest control methods work best for me. One of my go-to strategies is companion planting, where I pair crops that naturally repel pests. For example, planting marigolds around my potatoes helps deter aphids, and basil next to my beans keeps pests like aphids and spider mites at bay.

I also rely on homemade garlic or neem oil sprays for tough pests, which are safe for my plants but deadly to unwanted insects. Crop rotation is another key strategy—by rotating my high-calorie crops each year, I prevent pests from getting too comfortable in one spot. I’ve found that keeping a close eye on my garden and staying proactive with natural treatments keeps the pests under control, without disrupting the overall ecosystem.

Dealing with Storage Issues (e.g., Sprouting Potatoes or Molding Beans)

Storage can sometimes be tricky, especially with calorie-dense crops like potatoes and beans. I’ve had my fair share of issues with sprouting potatoes and moldy beans. For potatoes, I learned the importance of storing them in a cool, dry, and dark place, like a basement, where the temperature stays consistent between 40–50°F. I’ve also found that using burlap sacks or wooden crates helps them breathe better, preventing excess moisture from causing mold or sprouting.

For beans, moisture is the enemy—so once harvested, I ensure they are fully dried before storing them in airtight containers. If beans are left too moist, they can sprout or mold, which can ruin your harvest. I like to store them in glass jars or vacuum-sealed bags to ensure their longevity. By addressing these storage issues early on, I’ve been able to preserve my hard-earned crops and enjoy them well past harvest time.

Adapting to Different Climates

Adapting your survival garden to different climates is essential for success, and over time, I’ve learned to work with, not against, the elements. Whether I’m dealing with the dry heat of summer or the cold temperatures of late fall, I’ve figured out ways to tailor my garden’s needs to the climate. For hot, dry conditions, I use mulch around my plants to retain moisture and keep the soil temperature stable. I also prioritize drought-tolerant crops like beans and squash, which thrive in these conditions.

On the flip side, for colder climates, I focus on crops like potatoes and root vegetables that can handle frost and cool temperatures. In the early spring, I use row covers to protect tender seedlings from unexpected cold snaps. No matter your climate, it’s all about choosing the right crops and adjusting your gardening techniques to help your plants thrive, and I’m always finding new ways to make my survival garden more climate-appropriate.

Conclusion

Start Small and Expand

When starting your survival garden, I always recommend beginning small. It’s easy to get excited and want to plant a large garden all at once, but I’ve learned that starting with just a few crops and then expanding over time is the best approach. For me, I began with potatoes and beans, growing them in small raised beds. This allowed me to fine-tune my gardening skills, understand my soil, and get familiar with the needs of my crops without feeling overwhelmed.

Once I had mastered these basics, I slowly added more crops and increased the size of my garden. By starting small, I avoided burnout and made sure that my survival garden was manageable, helping me develop the confidence to grow my own food. As your knowledge and experience grow, so can your garden, allowing you to increase your self-reliance at a pace that feels right for you.

My Experience with Caloric Crops and How They’ve Benefited My Survival Plan

I’ve found that focusing on high-calorie crops in my survival garden has been a game-changer. Crops like potatoes, beans, and squash have provided not just a reliable source of food, but a way to store calories for the long term. In my early days of gardening, I realized that calories are one of the most important survival resources, so I prioritized planting crops that offered the most bang for their buck.

Potatoes, for instance, have been essential in providing energy, while beans are a fantastic source of protein. These crops have been crucial for feeding my family through tough times, especially when other resources were scarce. By focusing on caloric crops, I’ve been able to create a more sustainable lifestyle that allows me to rely less on stores and more on what I can grow in my garden. These crops have not only sustained us physically, but have also given me peace of mind knowing we have a steady food supply.
