Satsuma orange tree
I live in Houston, Texas. My tree is in a large pot on the patio. The fruits are bigger than golf ball size but I expected larger. Last years' fruit was delicious. Question: I have it mulched and I water periodically. I have NOT fertilized since spring. Do I need to do anything now?

I do believe that the fruit is not growing due to lack of water.
Container Citrus trees need more water than a tree in the ground. You should check the soil daily.
