Grow most ficus varieties in medium to bright light. If they don't get enough light, they'll grow slowly and have long stems, giving the plants an unattractive, lanky appearance. Most ficus varieties will tolerate some direct sun on their leaves when grown as houseplants, so they're great choices for sunny window sills. Water ficus when the top inch or so of the potting mix starts to feel dry to the touch. Ficus are quite resilient and survive inconsistent watering, but grow best when they get moisture on a regular basis. Fertilize ficus once or twice a year in spring and summer, when temperatures are warmer and plants are putting on more growth. Prune ficus anytime they start to get too large. Most types take well to pruning and will branch out, becoming thicker and bushier when you cut them back. One note: Ficus have a milky-white sap and some tips will drip sap after pruning. Use a rag or soft cloth to absorb the sap to prevent it from dripping on the floor. Also, if your ficus loses leaves when you first bring it home, don't worry: It should regrow new foliage once it's adapted to its new location.
