A fig needs hottest site possible. Also,for soil to be poor and roots restricted or you will get lots,of,growth and no fruit. The classic way is to,dig a large hole and,line it,with slabs including one at the,base. I,did just this a few years back and,had good fruits from it. Conversely, a friend of mine has,one in the open ground and it simply just grows without,any signs of fruiting. Figs need 2 summers to produce and ripen fruit. This means protecting tiny embryo figs over the winter with fleece so that they can regrow following spring. Figs in pots over wintered in a greenhouse are good option
