Pete...
Ditto, Martin.
God yes, cut down on the water as the figs start to ripen. I grow in containers, and throw plastic tarps over the pots if I know a rain storm is coming. I also cut way back on watering from a garden hose. I give the trees just enough to keep the leaves from flagging too badly.
Too much water at the wrong time will dilute the flavor, and sugar content, and could also lead to splitting and souring of your figs.
After the harvest...water as usual, and as needed.
Hope this helps.
