How can I prevent splitting tomatoes?Updated a year ago

Tomatoes will split when (1) there is a lot of heat and alternating rain or (2) if very dry weather is followed by days of rainfall. It is really caused by the drastic change in the amount of water in the fruit along with the heat. You can cover your plants with shade cloth to cut the amount of heat and always remember to keep the water reservoir full so the plants always have a consistent supply of water.
