【Product Features】
This is a co-developed product between our company, a sweet potato specialist, and Protoleaf, which boasts a top-class share in the sale of gardening soil. It was created as an item for casually enjoying sweet potato cultivation at home, following the 'Potato Bag' and 'Jagarico Bake-Tsuchi' co-developed with the Calbee Group.
Since it contains the necessary base fertilizer from initial growth to harvest, even beginners can easily start growing sweet potatoes by cutting the 'Beniharuka' sweet potato seedling to make cuttings, planting them vertically, and watering. The raw materials include easy-to-carry coconut coir and husk chips, and since it is 100% plant-derived, the soil can be disposed of as burnable waste after cultivation (*). It is a product that is not only good for growing sweet potatoes but also considerate of the global environment. *Please check as this varies by municipality.
【What is the 'Beniharuka' Sweet Potato Seedling?】
Selected by our company, a sweet potato specialist, 'Beniharuka' has a moist texture and is full of sweet nectar. By cutting the vines that grow from the pot seedling to make 'cuttings' and planting them in the 'Satsumaimo Bag,' you can easily enjoy growing sweet potatoes at home.
