- Orleans: Orleans sweet potatoes have a copper-colored skin and orange flesh. They are known for their excellent flavor and high yield. Orleans is a relatively new variety that has gained popularity in recent years due to its disease resistance and adaptability to various growing conditions.
- Evangeline: This variety has a light copper skin and orange flesh. Evangeline sweet potatoes are known for their high yield and good taste. They have good resistance to diseases and cracking, making them suitable for Arkansas’s growing conditions.
- Centennial: Centennial sweet potatoes have a light copper skin and orange flesh. They are known for their high yield and good flavor. Centennial is a versatile variety that can adapt well to different soil types and growing conditions.
It’s important to note that while these varieties are known to perform well in Arkansas, success may vary depending on factors such as soil type, climate, and specific growing conditions in your area. It’s always a good idea to consult with local gardening experts or your county extension office for more specific recommendations based on your location.
When to plant sweet potatoes in Arkansas
In Arkansas, the best time to plant sweet potatoes depends on the specific hardiness zone in which you reside. Arkansas is divided into several hardiness zones, ranging from Zone 6a to Zone 8b. Different zones have varying temperature ranges and growing seasons, which influence the appropriate planting time for sweet potatoes. Here’s a general guideline for planting sweet potatoes in different zones:
- Zone 6a to Zone 7a: In these colder regions of northern Arkansas, where the growing season is relatively short, sweet potatoes should be planted in late spring or early summer, around mid to late May. This timing ensures that the soil has warmed up sufficiently for proper tuber development.
- Zone 7b to Zone 8b: For central and southern parts of Arkansas, including Little Rock and Fayetteville, sweet potatoes can be planted a bit earlier, starting from mid to late April. These zones have longer growing seasons and warmer temperatures, which allow for an extended growing period.
It’s important to note that sweet potatoes thrive in warm weather and require a long growing season. Ensure that the soil temperature is consistently above 55°F (13°C) at a depth of 4 inches (10 cm) before planting, as cold soil can hinder their growth.
In all zones, proper soil preparation, watering, mulching, and vine maintenance are crucial for successful sweet potato cultivation. Be attentive to local weather conditions and frost warnings, especially in the colder zones, to protect your sweet potato crop from any unexpected cold snaps.
By considering Arkansas’s hardiness zones and planting sweet potatoes at the appropriate times, you can maximize your chances of a successful harvest and enjoy the sweet taste of homegrown tubers.
How to grow sweet potatoes
Growing sweet potatoes requires careful planning and attention to detail. Here are the steps and considerations to keep in mind:
- Climate and Soil Requirements: Sweet potatoes thrive in warm climates with a long growing season. They require well-drained, loose, and sandy soil with a pH level between 5.8 and 6.2.
- Variety Selection: Choose a sweet potato variety suitable for your climate and personal preferences. Some popular varieties include Beauregard, Covington, and Jewel.
- Starting Slips: Sweet potatoes are typically grown from slips, which are small rooted sprouts. You can purchase slips from a nursery or start your own by placing a sweet potato in a jar of water, allowing it to sprout. Once the slips are around 6-8 inches long, gently twist them off the sweet potato and place them in water to develop roots.
- Preparing the Bed: Prepare the planting bed by removing any weeds, rocks, or debris. Add organic matter such as compost or well-rotted manure to improve soil fertility and drainage.
- Planting: Plant the slips in the prepared bed after the last frost date in your area. Dig holes around 4-6 inches deep and place the slips with the roots down and leaves above the soil surface. Space the slips about 12-18 inches apart, with rows spaced 3-4 feet apart.
- Watering and Mulching: Sweet potatoes require consistent moisture, especially during the first few weeks after planting. Water deeply, but avoid overwatering, as it can lead to rot. Apply a layer of organic mulch, such as straw or wood chips, to conserve moisture and suppress weed growth.
- Fertilization: Sweet potatoes are heavy feeders and require regular fertilization. Apply a balanced organic fertilizer before planting and side-dress with additional fertilizer every 4-6 weeks throughout the growing season.
- Pest and Disease Management: Keep an eye out for pests like sweet potato weevils, aphids, and whiteflies. Use organic pest control methods such as handpicking, neem oil, or insecticidal soap. Rotate crops to prevent the buildup of soil-borne diseases.
- Harvesting: Sweet potatoes are ready to harvest when the leaves start to turn yellow or die back. Carefully dig them up using a garden fork or shovel, being cautious not to damage the tubers. Cure the harvested sweet potatoes in a warm, humid place for about 10-14 days to improve flavor and storage life.
- Storage: Store cured sweet potatoes in a cool, dry, and dark place with good ventilation. Avoid storing them in the refrigerator, as it can alter their taste and texture.
By following these steps and considerations, you can successfully grow your own sweet potatoes and enjoy a bountiful harvest.
When to harvest sweet potatoes
In Arkansas, sweet potatoes are typically harvested in late September to early October. The exact timing can vary depending on the specific variety of sweet potato being grown and the weather conditions throughout the growing season. It is important to monitor the plants closely for signs of maturity, such as yellowing of the leaves and the vines starting to die back. Additionally, you can gently dig around the base of the plant to check the size and development of the sweet potatoes. Once the sweet potatoes have reached a desirable size and the vines have started to decline, it is time to harvest them.
Common sweet potato plant problems and fixes
Common problems when growing sweet potatoes include:
- Poor soil drainage: Sweet potatoes require well-drained soil to prevent waterlogging, which can lead to root rot. To fix this, amend the soil with organic matter such as compost or aged manure to improve drainage.
- Pest infestations: Sweet potatoes can be susceptible to pests like sweet potato weevils, aphids, and whiteflies. Regularly inspect the plants for signs of infestation, and use organic pest control methods such as neem oil or insecticidal soap to manage the problem.
- Disease issues: Diseases like sweet potato scurf, fusarium wilt, and root rot can affect sweet potato plants. To prevent these diseases, practice crop rotation, avoid overwatering, and ensure good air circulation around the plants. If disease is already present, remove and destroy infected plants to prevent further spread.
- Lack of sunlight: Sweet potatoes require full sun, at least 6-8 hours per day, to thrive. If plants are not receiving enough sunlight, consider transplanting them to a sunnier location or pruning nearby trees or shrubs to allow more light to reach the plants.
- Improper watering: Overwatering can lead to root rot, while underwatering can cause stunted growth and poor tuber development. Water sweet potatoes deeply once or twice a week, ensuring the soil is moist but not waterlogged. Mulching around the plants can help retain moisture and regulate soil temperature.
- Insufficient nutrients: Sweet potatoes are heavy feeders and require adequate nutrients for healthy growth. Prior to planting, amend the soil with well-balanced organic fertilizer or compost. Additionally, side-dress the plants with a balanced fertilizer during the growing season to provide ongoing nutrition.
By addressing these common problems, you can increase the chances of successfully growing sweet potatoes.
