Most have no clue. Here’s why your tomatoes are splitting & what you can do

Heavy rainfall can saturate the soil and lead to excessive water uptake by the tomato plants. This sudden increase in water availability can cause the fruit to swell quickly, resulting in splits. Rainfall is a natural factor that is difficult to control, making it a common cause of tomato splitting in regions with unpredictable weather.

Applying too much fertilizer, particularly those high in nitrogen, can promote rapid growth in tomato plants. While growth is generally desirable, excessive growth can lead to splitting as the fruit expands too quickly for the skin to keep up. Balanced fertilization is key to preventing this issue.

Some tomato varieties are more prone to splitting than others due to their genetic makeup. Heirloom varieties, for example, often have thinner skins and are more susceptible to cracking. Choosing the right variety for your growing conditions can help minimize the risk of splitting.

Preventing tomato splitting involves a combination of proper watering techniques, soil management, and careful selection of tomato varieties. By implementing these strategies, gardeners can reduce the incidence of splitting and enjoy a bountiful harvest.

To prevent splitting, it's crucial to maintain a consistent watering schedule. Water your tomatoes deeply and regularly, aiming for about 1-2 inches of water per week. This helps to keep the soil evenly moist and reduces the risk of sudden water uptake.
