Understanding Purple Sweet Potato Growth
Purple sweet potatoes, also known as Okinawan sweet potatoes, are a variety of sweet potato with vibrant purple flesh and skin. They thrive in warm, sunny climates and require well-drained soil. While they are typically grown outdoors, with a bit of planning and care, you can successfully cultivate them indoors.
Choosing the Right Container
The first step to growing purple sweet potatoes indoors is selecting the right container. Since these plants can grow quite large, you’ll need a spacious pot. A container at least 12 inches in diameter and 12 inches deep is ideal.
- Material: Terracotta pots are a good choice because they allow for good drainage. Plastic pots are also suitable but may require more frequent watering.
- Drainage: Ensure the container has drainage holes at the bottom to prevent waterlogging.
Sunlight and Temperature
Purple sweet potatoes need plenty of sunlight to thrive. Place your container in a sunny spot that receives at least 6 hours of direct sunlight daily.
- South-facing windows: These are ideal for providing ample sunlight.
- Grow lights: If you don’t have enough natural light, consider using grow lights to supplement. Look for grow lights specifically designed for vegetables.
Temperature: Purple sweet potatoes prefer warm temperatures, ideally between 70-85°F (21-29°C).
Soil and Planting
Use a well-draining potting mix suitable for vegetables. You can purchase a pre-mixed potting mix or create your own by combining:
- Potting soil: Forms the base of the mix.
- Compost: Adds nutrients and improves drainage.
- Perlite or vermiculite: Improves aeration and drainage.
Planting:
1. Fill the container with the potting mix, leaving about an inch of space at the top.
2. Plant a purple sweet potato slip, which is a cutting taken from a mature plant. You can purchase slips online or at garden centers.
3. Gently press the slip into the soil, ensuring that the top 2-3 inches are above the soil line.
4. Water thoroughly after planting.
Watering and Fertilizing
Water your purple sweet potato regularly, keeping the soil consistently moist but not soggy. Allow the top inch of soil to dry out between waterings.
- Watering frequency: You’ll likely need to water 2-3 times per week, depending on the temperature and humidity in your home.
- Water quality: Use lukewarm water and avoid using cold water, which can shock the roots.
Fertilizing:
Purple sweet potatoes are heavy feeders and benefit from regular fertilization.
- Fertilizer type: Use a balanced liquid fertilizer specifically designed for vegetables.
- Frequency: Fertilize every 2-3 weeks during the growing season.
Harvesting and Storage
Purple sweet potatoes are typically ready for harvest 4-5 months after planting. You can check for harvest readiness by gently pulling on the vine. If the plant easily pulls away from the soil, it’s ready to harvest.
- Harvesting: Carefully dig up the sweet potatoes from the soil, being careful not to damage them.
- Storage: Store harvested sweet potatoes in a cool, dry, and dark place. They can last for several months if stored properly.
Enjoying Your Homegrown Purple Sweet Potatoes
Once you’ve harvested your purple sweet potatoes, enjoy their vibrant color and sweet flavor in a variety of dishes. They are delicious roasted, mashed, baked, or used in smoothies and desserts.
