Weeping figs (Ficus benjamina) grow throughout southeast Asia and northern Australia. In areas with below-30℉ outside temperatures, many people plant weeping ficus trees indoors.
Heat suits ficus plants from tropical Asia and Australia. Ficus thrives at 75°F–85°F. Low temperatures below 65°F cause leaf cold damage.
Regular, moderate watering helps ficus trees grow indoors. Nutrient-rich potting mix should always be wet. When the top soil dries, water the plant. A weekly schedule works.
Certainly, ficus are jungle plants. They like humidity. Summer humidity is rarely an issue. In winter, humidity causes problems inside homes.
The soil you plant your ficus tree in matters. A rich, nutrient-dense potting mix is best for ficus trees. Make sure your mix has good drainage to avoid waterlogging and root rot.
Ficus trees rarely need pruning. A springtime annual removal of dead branches and cutting back aggressive growth is enough to keep your tree's size and shape.
Aphids, mealybugs, scale, and spider mites attack ficus trees. If you have other houseplants, start a management regimen immediately if you discover any of the above insects or mites.
I always find dust on my indoor ficus tree. And cat fur. The last cat I owned was two years ago! Whatever, dust on houseplants is bad. Dust removal must be done safely.
