Six years ago I planted a fig tree that was given to me. I was told it was a "dwarf" fig but there has never been anything dwarf about it. Within a couple of years of planting the tree it began producing very large (nearly the size of an egg) figs that were very juicy and the best tasting fig I've eaten.
Then three years ago we had a snow storm (rare here in Alabama) with single digit temperatures and the tree died back to the roots. It has since grown back to its original size (probably 12' tall) but has never produced another fig. We do not water or fertilize the tree and never have. The tree I was given was started from a cutting and was not grafted.
Does anyone know why this tree has become sterile?
