Question

Fig Tree 3   Nick,  here is a photo of my fog tree showing one brown spot on one leave.
Please advise.   
Also, should I change the pot size again and since my tree is now about 18 months old, should I prune the roots ?  and if yes when.
Thank you Julia

Answer
Julia,,,that is nothing to worry about....Figs suffer from Rust fungus,,,but it begins by turning the leaf a lighter green and eventually falls off; that mark is nothing but a water spot, watch for irregularities like the blanching of the leaves, curling etc. this plant looks fine to me. If the roots are not creeping out of the drainage holes, then leave it be. Nick
