Q.Guava fruit problem
I got a guava tree that still small and young 10ft tall and 2 years old. This year produce one delicious fruit in season (summer), the about 5 more past the season (sept) this 5 guava still growing they are about 1.5″ long, but I see that have a like dry brown spot along all the fruit. I will like to know the cause and how I can take care that, thanks for you help.
Note; this guava plant came from a friend in Homestead Fl. And he told me that is a variety that dosen’t develop worms. (Pink in color)

That appears to be a fungal/bacterial issue. I would treat with a fungicide, and only water it when the soil remains dry to long periods.
