Why Potatoes Grow Tops, Not Tubers: 4 Reasons

28.05.2023 06:50

Quite often, gardeners face the problem of improper growth and development of potatoes: the tops stretch out and become fat, while the tubers remain small.

According to experts, there may be several reasons for such incorrect distribution of plant forces.

1. Varietal characteristics

There are some types of potatoes for which active growth of tops and late formation of fruits is the norm.

2. Excess of organic fertilizers

When the soil is oversaturated with organic matter (for example, manure), the tops become fat and grow very actively. At the same time, the plants have neither strength nor nutrition left for the formation of tubers.

3. Overfeeding with nitrogen

Too much nitrogen also provokes excessive growth of green mass in potatoes. In addition, this component slows down the vegetation of plants, which causes delayed tuber formation.

4. Lack of sunlight

Potatoes are light-loving crops, so they grow extremely reluctantly in shaded areas: their tops stretch out and become thin, and the tubers either do not form at all or grow very small.

Only by eliminating all these reasons can you grow not only tops, but also a good potato harvest.
