Why are the skins on my tomatoes splitting?
Posted by Dobies Staff on 12 December 2013 02:59 pm

The splitting of tomato skins can occur quite frequently on tomatoes grown outdoors and in the greenhouse.  It is caused by the onset of wet conditions following a dry spell or as a result of insufficient watering for a time.  The plants become deficient in water and then with the onset of rain or an increase in water supply, the plant cells enlarge rapidly leading to the splitting of the fruit skin. 

To avoid the problem ensure the roots are supplied with ample water.   The addition of well-rotted garden compost to the soil will increase the moisture holding capacity. 

Numerous cracks can develop on the fruit and this can be caused by wide fluctuations in the moisture content of the air.
