In respose to tarev - the plant has nice green leaves, it was dormant in winter but all the leaves grew back in late February, it looks perfectly normal except for the soft, squishy spot I have described, roots are also strong and plentiful and appear healthy, no rot that I can see and I have looked carefully. It was repotted last May. It was on the porch, the weather is in the high 70s and low to mid 80s and mostly sunny here, except for rain a few days ago. When the weather is good and sunny my trees go out into the yard to enjoy the hot Texas sun but if there is a chance of rain because I sleep odd hours due to my work I move them onto the porch to avoid getting too much water, I only let them have rain on bright sunny days, never cool or cloudy ones, when I am awake and can keep an eye on them so this tree has not been out in the rain but on a covered porch during the recent rainfall. I have taken it out of the pot to dry out to see if that would help so it is the garden shed by a window right now. I haven't done anything else to it because I really don't know what to do.
To Daisyl - I'm sorry as I said in my original post I can't provide pictures, my camera just died on me and I can't get a decent one with my phone, when I try to get close to the soggy spot it just gets blurry but a pic from further away you can't tell anything is wrong. I ceratinly would have included photos if I could.
