1. Sudden temperature drop leads to hollowing out
For example, when watering tomatoes, cold water is usually used. If the temperature of the cold water is too low, it can cause the roots to expand and contract, resulting in a decrease in the vitality of the roots.
If there is a lack of water during the ripening and swelling stage of tomatoes, it can lead to hollowing out. At this point, we should increase the water temperature when watering, preferably above 12 degrees Celsius, or store the water in the greenhouse to allow it to reach room temperature.
2. Excessive fruit retention leads to hollowing out
Too many fruits can also affect the development of tomatoes. The fruits on each plant compete with each other for nutrients, as nutrients are transported from bottom to top by the roots. Therefore, the lower fruits will begin to swell and ripen early.
However, nutrients are mostly absorbed by the lower fruits, leading to malnutrition in the upper fruits and resulting in hollowing out.
The solution is not to leave too many fruits on a single plant, and to control the number of fruits on each plant within a certain range according to the principle of leaving more fruits and leaving more fruits.
3. Insufficient water and fertilizer lead to hollowing out
The nutrients contained in the soil are also an important factor for the good development of tomatoes. If the water and fertilizer requirements for tomato growth are not met, it can lead to poor tomato development, insufficient nutrient supply, imbalance in the body, and the occurrence of hollowing.
It is necessary to supplement tomatoes with a large amount of phosphorus, potassium, and other fertilizers to meet their nutritional needs, and to keep the soil in the garden sufficiently moist. Watering should be based on factors such as weather conditions and tomato growth.
