Fruit Cracking and Splitting on Tomatoes
Commonly affects: Solanum lycopersicum (Tomato)
Concentric rings or radial cracks appear on the skin of ripening fruit, sometimes exposing the flesh underneath. Cracked fruit is still often edible if harvested promptly, but is more prone to rot.
Potential Causes
- 1Inconsistent watering, especially heavy watering or rain after a dry spell, causing rapid internal expansion
- 2Rapid temperature swings during ripening
- 3Some varieties being naturally more prone to cracking than others
Solution Steps
- 1Water consistently and evenly throughout fruit development rather than allowing dry-then-flood cycles.
- 2Mulch around the base of the plant to buffer soil moisture swings.
- 3Harvest slightly early during periods of heavy rain if fruit is already close to ripe, to avoid splitting.
- 4Consider crack-resistant varieties for future plantings if cracking is a recurring problem.
Prevention Tip
Consistent, even watering is the single most effective way to prevent cracking ïŋ― mulching heavily helps buffer against sudden moisture swings from rain.
