What to Do About Tomato Fruit Cracking? A Detailed Guide to Prevention and Control Techniques
1. Strengthen water and fertilizer management. Deeply plow the soil and apply more organic fertilizer so the plant's root system grows well. For late-autumn tomatoes, when temperatures drop sharply, pay even more attention to soil moisture management and avoid overly rapid moisture changes. In open-field cultivation, water more regularly to avoid drastic soil moisture changes when rain suddenly falls, and drain promptly after rain...

2. Tomato fruit cracking is related to the calcium and boron absorbed by the plant. Insufficient supply of calcium and boron can cause fruit cracking, so supplement calcium fertilizer and boron fertilizer in a timely manner and adjust the ratio of various nutrient elements in the soil. Nitrogen fertilizer and potassium fertilizer must not be applied in excess, otherwise they will affect the plant's absorption of calcium.
3. Pay attention to environmental regulation. Aging of the fruit skin also easily causes fruit cracking, and avoiding direct sunlight on the fruit shoulder is an effective measure to prevent fruit skin aging. Therefore, when selecting and keeping flower clusters and when pruning and tying vines, arrange the flower clusters on the inner side of the trellis so they are shaded by the plant's own leaves. When pinching off the growing tip, leave two leaves above the last fruit cluster to shade the fruit cluster. In protected cultivation, ventilate in a timely manner to reduce air humidity and shorten the time dew remains on the fruit surface.
