When growing ficus indoors, it is important to maintain a relatively high humidity around the plant. Regular misting or setting the ficus tree on a pebble tray filled with water is a great way to increase their humidity, but keep in mind that while they like high humidity, they do not like overly wet roots. If the top of the soil is wet, do not water as this means they have enough moisture. If the top of the soil feels dry to the touch, this indicates that they need water. Also while caring for a ficus plant, you should be aware that they are rapid growers and require plenty of nutrients to grow well. Fungus – Ficus trees are also occasionally affected by fungus, which can make the tree drop its leaves. Often, a ficus tree with a fungus will have yellow or brown spots on the leaves. To correct treat this reason for ficus tree leaves falling off, use fungicide (like neem oil) on the tree. And, once you have placed your ficus tree in your home, do not move it. Incorrect watering – Under watering or over watering both can cause a ficus tree to lose leaves. In an improperly watered ficus tree may have yellowing leaves and the ficus tree leaves may curl. Ficus' tropical origins make it a particularly welcome companion during winter weather. While you can get this effect indoors by growing ficus as a houseplant, some small tropical trees tolerate the cold well enough for outdoor planting. Several tropical thrive with moderate care in USDA hardiness zones 5 to 8. This restricts permanent outdoor planting of ficus to USDA plant hardiness zone 10b or warmer. In zone 10a, average annual cold temperatures reach between 30 and 35 degrees Fahrenheit; in zone 10b, lows are between 35 and 40 F, warm enough to minimize chances of exposure to even occasional temperature lows. By Heather Rhoades. Ficus trees are a common plant in the home and office, mainly due to the fact that they look like a typical tree with a single trunk and a spreading canopy. But for all of their popularity, ficus plants are finicky. If the top of the soil is wet, do not water as this means they have enough moisture. If the top of the soil feels dry to the touch, this indicates that they need water. Also while caring for a ficus plant, you should be aware that they are rapid growers and require plenty of nutrients to grow well. The Weeping fig, (Ficus benjamina), also known as the Benjamin's fig, or Ficus tree and often sold in stores as just ficus, is a species of flowering plant in the family Moraceae, native to Asia and Australia. It is the official tree of Bangkok.  Weeping Fig Plant. The weeping fig is part of the Ficus plant genus (scientific name: F. benjamina) and tree like, in looks. With large arching branches and long pointed leaves, it looks attractive indoors (apart from leaves dropping). Bright light is what keeps the weeping fig happy, that is partially shaded. A spot that receives some sun and shade during the day is great. As mentioned previously do not move the tree, not even turning it around to prevent leaves being shed. Ficus benjamina is the most widely grown ficus. Often several are planted in the same pot and braided into a decorative trunk. Avoid moving the plant around once you find a good location for it; leaves drop readily in response to environmental changes. Ficus plants range from large trees to woody shrubs to trailing vines. All grow best in medium to bright light, although they will tolerate low light for short periods. They grow well at normal room temperature. Allow the soil of tree and shrub forms to dry out between waterings. Bright, direct light may result in scalding of the leaves and leaf loss. Ficus trees also cannot tolerate low temperatures or drafts. They need to be kept in temperatures above 60 F. (16 C.) and actually prefer temperatures above 70 F. (21 C.). If the top of the soil is wet, do not water as this means they have enough moisture. If the top of the soil feels dry to the touch, this indicates that they need water. Also while caring for a ficus plant, you should be aware that they are rapid growers and require plenty of nutrients to grow well. Light and Soil. Plant the ficus in a well-draining potting mix. Purchase a loamy soil with added vermiculite or perlite for drainage, or mix your own. Use 3 parts loam 1 part peat and 1 part sand for a well-draining mixture. Plant in a deep pot with drainage holes so the water can run out.
