Last year all the figs shriveled up and fell off, and about mid August the leaves began to turn yellow. Figs are extremely shallow rooted and consequently very susceptible to stress. I think that is why the figs shriveled up and the leaves turned yellow. Mulch the plant heavily and if possible put a soaker or drip hose under the mulch. This way you can water it heavily and then the mulch will help conserve the moisture.
Water is extremely important during the hot summer months.
About three years ago my wife brought home a cutting from a Fig tree. We planted it first in a pot to take root and then last fall transplanted it to the ground. It is now about seven feet tall and has good healthy leaves. My problem is though I've noticed flowers it never produces fruit. The fig is actually an inside out fruit.
