It is usually a sign of Low Calcium in the soil. you can get some products that contain calcium but they are mixed element sprays etc. you run the risk of putting to much of something else in, that is not required. Best tip I have been given is to place all your eggshell in water for 2 or 3 weeks, then water the base of the plants with this. and next time your preparing your soil, bury all your used (crushed) eggshell into the soil of the garden bed. I just started to use Eggshell water a month ago and I have already picked the new growth fruit that has no sign of the rot, some still do but instead of all of them rotting I get to eat 7 out of 10 now. Hope this helps.
