Tips Sweet potato

Summary

Soil preparation

  • Sweet potatoes prefer light, well-drained soil rich in organic matter. Heavy or clayey soil can hinder their development.
  • The ideal pH for sweet potatoes is between 5.8 and 6.2. This type of soil promotes healthy root and tuber growth.
  • Before planting, enrich the soil with well-rotted compost or manure to improve fertility.
  • Well-prepared soil allows roots to spread freely, promoting better sweet potato harvests.

Planting

  • Plant sweet potatoes after the last frost, once the soil is warm enough. This allows the roots to grow in optimal conditions.
  • Space sweet potato plants 30 to 45 cm apart to allow them to spread out and produce large tubers.
  • Plant slips (young sweet potato shoots) in rows spaced 1 to 1.5 meters apart to ensure good root development.
  • Make sure the slips are buried well, but leave the base slightly above the soil to prevent rot.

Watering

  • Sweet potatoes require regular watering, but avoid overwatering as this can lead to fungal diseases.
  • Keep the soil slightly moist during tuber growth, but avoid excess water to maintain harvest quality.
  • Reduce watering as harvest time approaches to allow the tubers to firm up and develop their flavors.
  • Use a drip irrigation system for precise watering and to prevent excessive moisture on the leaves.

Fertilizer

  • Sweet potatoes benefit from regular organic fertilizer, especially compost or manure to enrich the soil.
  • Avoid using fertilizers too rich in nitrogen, as this can lead to excessive stem growth at the expense of tubers.
  • Apply a balanced fertilizer rich in potassium and phosphorus to promote root and tuber formation.

Harvesting

  • Sweet potatoes are ready to harvest when they have reached an appropriate size and the leaves begin to yellow.
  • Harvest sweet potatoes before the cold weather sets in, as they are sensitive to frost and can be damaged.
  • To harvest, use a fork to carefully loosen the soil and avoid damaging the tubers.
