When planting a fig tree, do not apply fertilizer at planting time. When new growth begins to emerge, and rain or irrigation settles the soil, apply a granulated organic fertilizer, or ammonium sulphate. Generally, two cups of fertilizer a year split into 3 to 4 applications should be sufficient, or follow rates recommended on label. Spread the fertilizer evenly over a circle 18" in diameter with the Fig plant in the center. Repeat this same fertilization process in March and July of the second year spreading twice as much fertilizer as the year before over a circle 24" in diameter with the fig plant in the center. Continue to increase the amount of fertilizer applied yearly until the bushes are 8-10 feet tall. Spread the fertilizer evenly under and around the branches. Water the plants throughout the growing season when rainfall is not adequate. Irrigation of young plants is especially important during the first season or two. Always keep a sufficient layer of much around your fig trees to control competition from weeds and help retain moisture.
