Plant Care & Growing Tips
Successfully growing purple sweet potatoes begins with proper planting and attentive care. These plants thrive in warm conditions, preferring full sun exposure. Ensure they receive at least 6-8 hours of direct sunlight daily for optimal tuber development. Plant your Okinawa sweet potato slips outdoors after the last frost has passed, typically when soil temperatures consistently reach 65°F (18°C) or warmer. They are propagated from rooted slips or vine cuttings, not from seeds, ensuring true-to-type plants.
The ideal soil for these sweet potatoes is loose, well-drained sandy or loamy soil with a pH between 5.5 and 6.5. Avoid heavy clay soils or areas prone to waterlogging, as this can lead to root rot. Space the slips 12-18 inches apart within rows, with rows approximately 3 feet apart to allow for ample vine growth and tuber expansion. During the establishment phase, keep the soil evenly moist. Once the plants are established, water moderately, allowing the top inch or two of soil to dry out slightly between waterings to prevent cracking or rotting of the tubers. Overwatering can be detrimental, so proper drainage is crucial.
For fertilization, use a balanced or low-nitrogen formula. Too much nitrogen will encourage excessive leafy growth at the expense of tuber development. A fertilizer with a higher phosphorus and potassium content is generally more beneficial. These plants are relatively heat and humidity tolerant, making them resilient in many warm climates. Harvest typically occurs 90-120 days after planting, when the leaves begin to yellow. Handle the tubers gently to avoid bruising. After harvesting, cure them in a warm, humid environment (85°F and 85-90% humidity) for 7-10 days before storing them in a cool, dry, and well-ventilated space for long-term enjoyment. This curing process sweetens the potatoes and improves their storage life, making your edible sweet potato plant efforts truly worthwhile.
