Why Are My Tomatoes Splitting And Cracking – Full Discussion
Tomatoes can split and crack due to various reasons. One common cause is irregular watering practices. When tomato plants experience fluctuations in soil moisture, particularly when they receive sudden heavy watering after a period of dryness, the tomatoes can expand too rapidly, and the skin may not stretch to accommodate the growth, causing them to split.
Another reason for splitting and cracking is excessive heat. High temperatures can accelerate the ripening process, leading to rapid expansion of the tomatoes and an increased likelihood of cracking. Genetics can also play a role. Some tomato varieties are more prone to splitting and cracking than others.
To prevent splitting and cracking, it is important to maintain consistent watering practices, ensuring that the plants receive regular, deep watering. Mulching the soil around the plants can help to retain moisture and regulate soil temperature. Providing shade or using shade cloth during extreme heat can also help to protect the tomatoes.
Causes Of Tomato Splitting And Cracking
There are several reasons why tomatoes may split and crack as they ripen. One common cause is fluctuations in watering. If the plants are inconsistently watered, the tomatoes may absorb water too quickly, causing the fruit to expand rapidly and lead to splitting.
Conversely, if the plants receive a sudden heavy downpour after a drought, the rapid uptake of water can also cause the tomatoes to split. Another factor that contributes to splitting is uneven growth.
If the tomatoes are growing too quickly or exposed to extreme temperature changes, the skin may be unable to keep up with the internal growth, resulting in cracks. Additionally, certain tomato varieties are more prone to splitting than others, so it is important to select varieties that are known for
