Usually it's caused by a lack of water during the extreme temperatures of the summer sun. <br /> <br />Prevent your tomatoes from splitting and cracking during the hot summer months by following some simple steps. <br /> <br />It's important to note that many people don't know that split tomatoes can harbor a wealth of bacteria that can kill the tomato plant. So if you happen to notice a split tomato still on the vine... pull it off and if it's ripe, eat it. Cut around the cracked area and use like you would any other tomato. <br /> <br />The most important thing to remember is to not let the plant dry out. Water on a consistent schedule. <br /> <br />Use compost instead of fertilizer and put mulch around the plants as this allows proper drainage and airflow. <br /> <br />Remember if it's extremely hot tomatoes like some shade just like humans.
