What is the name of the fertilizer you give to potatoes?

Potatoes benefit from a balanced fertilizer that is high in potassium, such as a 10-20-20 or 5-10-10 formulation. Additionally, fertilizers like bone meal or compost can provide essential nutrients. It's important to avoid excessive nitrogen, as it can lead to lush foliage at the expense of tuber development. Applying fertilizer at planting and during the growing season can help ensure healthy potato growth.
