Hybrid Okinawa Sweet Potato Seeds

1. Sowing Technique: Plant seeds or sprouted slips 5–8 cm deep directly into well-cultivated, loose soil mounds or ridges to encourage uniform downward root growth.
2. Sunlight Requirements: Position cultivation beds or grow containers in a wide-open area that receives at least 6–8 hours of full, intense direct daily sunlight.
3. Soil Condition: Grow in deeply loosened, well-aerated sandy loam soil heavily amended with organic compost; avoid compacted soils or heavy clay which stunt and deform tubers.
4. Watering Schedule: Maintain a steady, moderate watering routine to keep the soil evenly damp; sharply reduce watering 2–3 weeks before harvesting to prevent tuber rotting and concentrate sugars.
5. Harvesting Timing: Harvest carefully using a garden fork when the creeping green vines begin to yellow and fade, ensuring you do not bruise or slice the delicate outer skins.
