Top Reasons Why Tomatoes Split
Reason 1: Inconsistent Watering Practices
When tomatoes experience a dry spell followed by heavy watering, the sudden influx of moisture makes the fruit swell rapidly. The skin can’t keep up and cracks as a result.
Reason 2: Rapid Growth Spurts
Warm temperatures and ample sunlight can trigger rapid growth. Young, developing tomatoes are especially prone to splitting during these spurts.
Reason 3: Excessive Rainfall
Heavy rains quickly saturate the soil, causing tomatoes to absorb too much water at once, which leads to cracking.
Reason 4: Over-Fertilization
Too much fertilizer, especially nitrogen, encourages rapid growth. While growth is good, excessive swelling causes the skin to split.
Reason 5: Varietal Susceptibility
Some tomato varieties naturally have thinner skins. Heirloom tomatoes, for example, are more prone to cracking than hybrids bred for thicker skins.
