If you are growing many fig trees, plant the cuttings at least 15 to 20 feet apart. Ensure that the plants get full sunlight and sufficient space for growth. For proper maintenance and care, fertilize the trees annually; but, if you have a dense soil, fertilize when the bud swells. In borderline climates, if grown outdoors, make sure that the tree gets proper protection from frost, otherwise its roots may get damaged. The tree can be harvested as soon as the fruits become soft and start ripening.
