Ficus benjamin: Answer: ficus benjamin and aphids
Hello and thank you for submitting your questions to the Questions and Answers section of our website. Your ficus benjamin is certainly infested with aphids. Aphids are small insects that feed on plant sap and secrete a sugary liquid, honeydew, which is that strange sticky substance she finds on leaves and on the floor. This substance, in addition to being a good nourishment for other insects in nature, such as ants for example, is sticky and annoying in urban and domestic environments, because it affects the most delicate surfaces in the long run, such as the bodywork of parked cars. under the plants. We therefore advise you to eliminate these insects from your ficus plant, also because soon you may find numerous ants at home trying to feed on this honeydew.
The fight against aphids involves two ways, the chemical one which occurs through specific insecticides, and the biological one which occurs through natural predators, which is difficult to implement in a domestic environment. So to eliminate these insects from your ficus plant, we recommend that you go to a garden center and get a special product. Broad-spectrum insecticides are usually used against aphids that exploit various active ingredients such as Imidacloprid, Pirimicarb, Quinalphos, Fenitrothion, Malathion, Triclorfon, Diflubenzuron and Endosulfan.
Toxicity of Ficus Benjamina
Ficus benjamina is a fig tree that is commonly grown indoors. It is also commonly known as the weeping fig. Ficus benjamina is the most common fig species, and is part of the Moraceae family. The trees are notable for their glossy green, ovoid foliage that taper to a point. The drooping leaves are the source of the name "weeping fig," as they give the plant a melancholy appearance. The sap that is emitted from the Ficus benjamina is toxic. The small fruits of the tree, although inedible, are non-toxic.
- Ficus benjamina is a fig tree that is commonly grown indoors.
- Ficus benjamina is the most common fig species, and is part of the Moraceae family.
The sap that is emitted from all parts of the Ficus benjamina is highly toxic. Contact with the sap can lead to both allergic and dermatitis reactions. As a result, the plants should be kept away from small children.
How to Save a Ficus Benjamina
Ficus plants (Ficus benjamina) are popular house plants grown in the United States. They are grown for their pretty foliage that is either green or variegated and their unique growth habit. A ficus is one of the few houseplants that grows into a small tree inside a home if trained properly. Many times, ficus plants are grown with several trunks that are tied together or woven into an attractive pattern. These "braided" trunks meld together and form an attractive natural structure. Ficus plants can live for many years in the same container, but occasionally a ficus plant becomes stressed and needs to be revived.
Look carefully at your ficus plant and identify any dead limbs. A limb may be leafless but not dead, so test the limb by slightly scratching the outer layer of the limb with your thumbnail. If there is green underneath the bark, the limb is still alive. If the limb is dead, cut it back to a main branch.

Continue clearing all dead limbs until they are all removed. Then, trim the live limbs into the desired shape of the plant. The shape should be that of a small tree with a canopy on top of a bare trunk. The canopy should be one-third the overall size of the plant. In other words, two-thirds of the plant is the trunk and one-third is the canopy. Even if you are left with only a few live limbs, trim back using the one-third / two-third rule. Don't worry about the white latex sap that oozes from the cut areas. It will dry and seal over the wounds.

Take the ficus plant outside and remove from container. If re-potting in the same container, clean the container well with hot, soapy water and rinse well. Lightly shake old soil off the root base of the ficus plant and re-pot using new potting soil. Replant at the same depth it was previously planted unless a lot of roots were exposed, then it can be planted slightly deeper to cover the roots.
If planting in a new container, use a container that is only 2 inches larger in diameter than the old container. This prevents a lot of wet soil sitting around the root base that is not being utilized by the plant. Ficus plants are one of the few plants that do not mind being root-bound.

Water thoroughly, wait 30 minutes, then add a one-half dose of water-soluble fertilizer for house plants. Continue adding the fertilizer mixture until it runs from the bottom of the container. Let the container drain. Move indoors to a location with dappled shade, but not direct sun. Every week, fertilize with a one-half dose of water soluble fertilizer for house plants. The plant should start putting out new growth in four to six weeks. Keep the ficus plant trimmed to shape for a fuller and more attractive growth habit.
Ficus benjamina is a tree reaching 30 m (98 feet) tall in natural conditions, with gracefully drooping branchlets and glossy leaves 6–13 cm (2 3 ⁄8 – 5 1 ⁄8 inches), oval with an acuminate tip. The bark is light gray and smooth. The bark of young branches is brownish. The widely spread, highly branching tree top often covers a diameter of 10 meters. It is a relatively small-leaved fig. The changeable leaves are simple, entire and stalked. The petiole is 1 to 2.5 cm (3 ⁄8 to 1 inch) long. The young foliage is light green and slightly wavy, the older leaves are green and smooth the leaf blade is ovate to ovate-lanceolate with wedge-shaped to broadly rounded base and ends with a short dropper tip. The pale glossy to dull leaf blade is 5 to 12 cm (2 to 4 1 ⁄2 inches) cm long and 2 to 6 cm (1 to 2 1 ⁄2 inches) wide. Near the leaf margins are yellow crystal cells ("cystolites"). The two membranous, deciduous stipules are not fused, lanceolate and 6 to 12 mm (1 ⁄4 to 1 ⁄2 inch) (rarely to 15 mm or 9 ⁄16 inch) long. 
F. benjamina is monoecious. The inflorescences are spherical to egg-shaped, shiny green, and have a diameter of 1.5 cm (1 ⁄2 inch). In the inflorescences are three types of flowers: male and fertile and sterile female flowers. The scattered, inflorescences, stalked, male flowers have free sepals and a stamen. Many fertile female flowers are sessile and have three or four sepals and an egg-shaped ovary. The more or less lateral style ends in an enlarged scar.
The ripe figs (collective fruit) are orange-red and have a diameter of 2.0 to 2.5 cm (3 ⁄4 to 1 inch).
In tropical latitudes, the weeping fig makes a very large and stately tree for parks and other urban situations, such as wide roads. It is often cultivated for this purpose.
F. benjamina is a very popular houseplant in temperate areas, due to its elegant growth and tolerance of poor growing conditions it does best in bright, sunny conditions, but also tolerates considerable shade. It requires a moderate amount of watering in summer, and only enough to keep it from drying out in the winter. Longer days, rather high and moderate day temperatures at night are favorable conditions for great appreciable growth in a short time. It does not need to be misted. The plant is sensitive to cold and should be protected from strong drafts. When grown indoors, it can grow too large for its situation, and may need drastic pruning or replacing. F. benjamina has been shown to effectively remove gaseous formaldehyde from indoor air. 
The NASA Clean Air Study determined that this plant was effective at removing common household air toxins formaldehyde and xylene.
The fruit is edible, but the plant is not usually grown for its fruit. The leaves are very sensitive to small changes in light. When it is turned around or relocated, it reacts by dropping many of its leaves and replacing them with new leaves adapted to the new light intensity. The plant is also sensitive to changes in environmental factors such as temperature, humidity and moving.
Numerous cultivars are available (e.g. 'Danielle', 'Naomi', 'Exotica', and 'Golden King'). Some cultivars include different patterns of coloring on the leaves, ranging from light green to dark green, and various forms of white variegation.
In cultivation in the UK, this plant  and the variegated cultivar 'Starlight'  have gained the Royal Horticultural Society's Award of Garden Merit. 
The miniature cultivars, especially 'Too Little', are among the most popular plants for indoor bonsai.
The United States Forest Service states, "Roots grow rapidly, invading gardens, growing under and lifting sidewalks, patios, and driveways." They conclude that its use in tree form is much too large for residential planting therefore, in these settings, this species should only be used as a hedge or clipped screen. 
These trees are also considered a high risk to succumb to storm gale winds in hurricane-prone south Florida.  As a consequence in many jurisdictions in South Florida no permit is required for removal of these trees.  The South Florida Water District recommends removing these trees. 
The plant is a major source of indoor allergens, ranking as the third-most common cause of indoor allergies after dust and pets.  Common allergy symptoms include rhinoconjunctivitis and allergic asthma. Ficus Plants can be of particular concern to latex allergy sufferers due to the latex in the plants, and should not be kept in the environment of latex allergy sufferers.  In extreme cases, Ficus sap exposure can cause anaphylactic shock in latex allergy sufferers. The consumption of parts of plants leads to nausea, vomiting, and diarrhea. Exceptions are the edible fruits.
Allergy to Ficus plants develops over time and from exposure. The allergy was first observed in occupational settings amongst workers who regularly handled the plants. A study of workers at four plant-leasing firms showed that 27% of the workers had developed antibodies in response to exposure to the plants. 
Watering and fertilizing
If you consider the site and soil conditions, a ficus (Ficus benjamina) is basically very easy to maintain. Although you should regularly supply your Benjamini with water during the vegetation period, always allow the bale surface to dry thoroughly before watering the Ficus benjamina again. You can determine the right time with the so-called finger test: If the soil still feels slightly damp at the top of the pot, you should wait until you have soaked it. A coaster under the planter is also recommended, as birch figs (Ficus benjamina) are sensitive to waterlogging. In the cachepot, excess water often goes unnoticed. For watering, it is best to use room-warm rainwater or stale tap water that is not too rich in lime.
From March to September, you should fertilize your Ficus benjamina about every two to three weeks with a liquid green plant fertilizer, which is administered according to the dosage recommendation on the bottle with the watering water. If possible, use a branded product, because studies show again and again that cheap fertilizers from discounters sometimes have major shortcomings with regard to their nutrient composition. In winter, fertilization every six to eight weeks is completely sufficient.
Looking for one plant with which furnish home and that it has few claims? Simple: bet everything on Sansevieria. The philosophy of this perennial herbaceous species from the leaves of green and striped color there is only one: minimum effort maximum yield. You can place it in any environment without too many hesitations: inside an apartment, in the garden but also on the balcony. This plant it doesn't need too much light, therefore it lends itself to living even in darker environments, it must be kept away from heat sources is watered sporadically. Symbol of resistance, vigor and tenacity, cleans the air of harmful substances and carbon dioxide. In addition, there are different variants, some larger of others. The height of a Sansevieria, in fact, ranges from a minimum of 30 cm up to a maximum of 1 m. Obviously, at the time of purchase, the price varies depending on the size.
