The ficus is one of the most popular indoor trees. The ficus's glossy green leaves are not showy, but what it lacks in ornamental value it more than makes up for with low maintenance. A ficus tree requires very little fuss. In fact, it won't tolerate it. The ficus is famous for dropping its leaves whenever its available light, temperature or position changes even a little. But if kept well watered and fertilized, your ficus will soon bounce back from any minor setbacks.
Calculate the manufacturer-recommended amount of water-soluble fertilizer for a houseplant of your ficus's size and reduce the amount by half.
Mix the fertilizer with the amount of water you usually give your ficus and pour it evenly over the soil.
Repeat steps 1 and 2 once every three to four weeks while your ficus plant is actively growing and producing new leaves.
Reduce the frequency of fertilization if your ficus's growth slows down in fall and stops in winter. Fertilize it only once, when fall begins, and stop fertilizing altogether during the winter. However, if your ficus continues to produce growth throughout the year, continue to fertilize it monthly.
