Q What is tomato splitting?

A The tomato fruits develop normally, but as they ripen the skins split suddenly, often around the
stalk end.

Q Is there anything I can do if my tomatoes split?

A Split fruits can be eaten – you just need to be quick about it. They soon become unappetising as grey mould (botrytis) enters the damaged areas.

Q How can I avoid tomatoes splitting?

A Excessively hot or somewhat dry growing conditions cause a reduction in the swelling rate of the fruit and a thickening of the skin. When conditions improve (usually after watering), the fruit puts on a growth spurt and the skin splits. Regular watering and the provision of some shading during very hot, bright periods should reduce the problem.
