I want to warn you that not all common fertilizers are suitable for potatoes and can harm their growth. To avoid mistakes, I will tell you about several types of fertilizers that should not be used.

organics and manure

Organic fertilizers and manure are very useful and natural substances, but they should not be used when planting tubers in holes. With this method of adding fertilizers, they become useless, since the need for organic matter and nitrogen from the potato arises precisely during the flowering period. When planting, the manure simply does not have time to decompose and provide nutrients.

It would be more correct to add manure and humus in autumn or spring, when the soil is dug up. This way the plant will receive the maximum amount of nutrients necessary for active growth.

ash

Ash is one of the most popular fertilizers among gardeners, but it is not suitable for potatoes. This type of plant does not like alkaline soils, and the ash creates it. In order not to damage the plantings, it is best to put ash on the garden bed in the fall.

You can also mix ash with biscuit, as this is an ideal combination of components that greatly benefits the potatoes.
