Choosing the Right Sweet Potato Varieties for Your Survival Garden
Not all sweet potatoes are the same. Different varieties can offer various benefits, so choose the one that best suits your climate and needs.
1. Beauregard
Beauregard sweet potatoes are one of the most common varieties. They’re easy to grow, produce high yields, and have a rich, sweet flavor. This variety is ideal for both beginner gardeners and those with more experience.
2. Jewel
Jewel sweet potatoes are another popular variety, known for their deep orange flesh and sweet, smooth flavor. They have a higher moisture content, making them perfect for baking or mashing.
3. Georgia Jet
Georgia Jet sweet potatoes are fast-growing, making them a great option if you have a shorter growing season. They are known for their dark orange flesh and rich flavor.
4. Purple Sweet Potatoes
For something unique, try growing purple sweet potatoes. With their vibrant color and slightly firmer texture, they’re great for roasting and have a slightly nutty taste.
5. White Sweet Potatoes
White sweet potatoes are less sweet than the orange varieties, but they have a delicious, nutty flavor and a smoother texture. They’re perfect for people who prefer a milder flavor.
How to Grow Sweet Potatoes: Step-by-Step
Sweet potatoes are relatively easy to grow, but they do require a bit of attention to ensure a bountiful harvest. Here’s how to get started:
1. Choose the Right Location
Sweet potatoes thrive in full sun and warm soil. They need at least 6 hours of sunlight per day to grow properly. Choose a location with well-drained, loamy soil that’s rich in organic matter. The soil should be warm (about 65-85°F) before planting, as sweet potatoes are heat-loving plants.
2. Preparing the Soil
Sweet potatoes prefer slightly acidic soil (pH 5.8-6.2). Before planting, amend the soil with compost or organic matter to improve its structure and fertility. You can also use a balanced fertilizer to ensure that your plants get the nutrients they need to grow strong and healthy.
3. Starting from Slips
Unlike regular potatoes, sweet potatoes are grown from "slips" – young plants that are grown from the tubers. To start slips, place a sweet potato in a jar of water, half-submerged. Place the jar in a warm, sunny location and wait for the slips to sprout. Once the slips are around 6 inches long, carefully cut them off the potato and let them root in water for a few more days before planting.
4. Planting Sweet Potatoes
Spacing: Sweet potatoes need plenty of space to grow, so plant your slips about 12-18 inches apart. If you’re growing in rows, space the rows 3-4 feet apart to allow room for the vines to spread.
Planting Depth: Dig a shallow trench (around 4-6 inches deep) and lay the slips horizontally in the trench. Cover the slips with soil, making sure the leaves are above the ground level.
5. Watering and Mulching
Sweet potatoes need consistent moisture, especially in the early stages. Water them regularly, but don’t over-saturate the soil, as this can cause rot. Mulching around the plants with straw, leaves, or grass clippings will help retain moisture and keep weeds at bay.
Caring for Sweet Potatoes as They Grow
1. Fertilizing
Sweet potatoes are moderate feeders, so you’ll want to fertilize them periodically throughout their growing season. Use a balanced fertilizer with a slightly higher potassium ratio to promote healthy root development. Too much nitrogen can lead to excessive vine growth, so keep that in check.
2. Pruning and Managing Vines
Sweet potato vines can grow long and sprawling. While you don’t need to prune them, you may want to trim back excess growth to prevent the vines from taking over your entire garden. This will also help focus the plant's energy on root production.
3. Pest Control
Sweet potatoes can be prone to pests like sweet potato weevils and aphids. To prevent damage, regularly inspect your plants for signs of pests and take action immediately if you spot any. Neem oil or insecticidal soap can be effective natural solutions for pest control.
4. Disease Prevention
Sweet potatoes can suffer from soil-borne diseases, such as fusarium wilt and root rot. To minimize the risk, rotate your crops each season and avoid planting sweet potatoes in the same spot year after year. Ensure proper soil drainage, as sweet potatoes don’t like wet feet.
Harvesting Sweet Potatoes: When and How to Do It
Sweet potatoes take around 90 to 170 days to mature, depending on the variety and growing conditions. Once the vines begin to yellow and die back, it's time to harvest. However, you’ll want to wait for the soil to dry out before digging them up to prevent damage.
To harvest:
Gently dig around the base of the plant with a garden fork or shovel, being careful not to bruise or damage the tubers.
Shake off excess dirt but avoid washing the potatoes until you’re ready to use them.
Cure your sweet potatoes in a warm, humid area for 7-10 days to help them develop their full flavor and store more effectively.
Storing Sweet Potatoes for Long-Term Use
Proper storage is key to keeping your sweet potatoes fresh for as long as possible. Once cured, sweet potatoes should be stored in a cool, dark, and dry location, such as a root cellar or pantry. Ideal storage temperatures are around 55-60°F. If stored correctly, sweet potatoes can last for several months.
Sassy Prepper’s Tips for Growing Sweet Potatoes
➡ Use Raised Beds or Containers: If your soil is heavy or poorly drained, try growing sweet potatoes in raised beds or containers. This allows for better soil aeration and drainage.
➡ Avoid Over-Watering: Too much moisture can cause the tubers to rot, so make sure the soil is well-draining and avoid watering excessively, especially near harvest time.
➡ Companion Planting: Grow sweet potatoes alongside beans or other crops that help fix nitrogen in the soil, as sweet potatoes don’t require much nitrogen.
Why Sweet Potatoes Are Essential for Preppers
Sweet potatoes are an essential prepper crop, not only because of their nutritional value but also their long storage life and ease of cultivation. They’re a reliable source of energy and vitamins, making them a perfect addition to your survival pantry. Whether you're planning to bake, fry, or mash them, sweet potatoes will always deliver a nourishing and satisfying meal.
With a little attention and proper care, sweet potatoes will thrive in your garden, ensuring you have a healthy, nutrient-rich crop to sustain you year-round. So roll up your sleeves, grab your gardening tools, and get ready to grow one of the most delicious and versatile crops for your survival garden!
