Why Tomatoes Don't Swell: Causes and Solutions

During tomato cultivation, many farmers often report that their tomatoes don't swell or swell slowly, which deals a serious blow to yields. So what causes tomatoes not to swell? Let's find out together.

1. Improper cultivation management

Tomatoes not swelling is mostly caused by improper cultivation management, and the essential reason is insufficient nutrition or failure to timely supplement the nutrients needed for growth, such as unreasonable fertilization, temperature too low or too low, or insufficient water supply. So we should adopt a reasonable fertilization method according to the different growth stages of tomatoes and the soil fertility conditions. During the vigorous reproductive growth period, fertilization should focus on phosphorus and potassium fertilizers and control nitrogen fertilizer application, which can inhibit vegetative growth and promote reproductive growth.

2. Unbalanced growth

Because plant overgrowth or excessive vigor growth causes reproductive growth and vegetative growth to be uncoordinated, thereby inhibiting the normal growth of the fruit, which is commonly called growing the plant but not the fruit. The main causes of this phenomenon are excessive nitrogen fertilizer, a small day-night temperature difference, and excessive watering. So during management, the plant's overgrowth and excessive vigor growth must be controlled. Plant overgrowth weakens reproductive growth, causing a drop in fruit set rate and no fruit swelling. Controlling overgrowth means controlling the amount of watering, appropriately reducing watering, and adopting the principle of frequent light watering; flooding irrigation should not be used. When watering, lower the night temperature and widen the temperature difference, which can promote reproductive growth. At the same time, spray trace elements such as boron and calcium.

3. Too much nitrogen fertilizer

Applying too much nitrogen fertilizer is a common fertilization mistake in greenhouse cultivation, because fertilizers antagonize each other. If too much nitrogen fertilizer is applied, it will affect the plant's absorption of elements such as potassium, boron, calcium, and magnesium, and these substances are important elements for tomato swelling. Once deficient, the fruit cannot swell. So during the growth period, nitrogen fertilizer application must be controlled, and phosphorus and potassium fertilizers and trace element fertilizers should be appropriately applied as supplements.
