In addition to the variety, you can increase the potassium content in the soil by applying potassium fertilizer (K), such as Mr Ganick 426 Organic Melon Vegetable Fertilizer. This will produce larger and tastier sweet potatoes.
Fertilizing tips:
- Apply fertilizer once a week.
- Loosen the topsoil, dig a hole, sprinkle the fertilizer, and cover it with soil. This helps the plants absorb nutrients more effectively.
