Top Tips & Info

  • Care Difficulty - Easy to Moderate
  • Provide a bright, indirect setting away from the intense sun. A splash of winter morning sunlight is highly beneficial for its health over the dormancy period.
  • Allow the soil's top third to dry out in between waters, reducing this slightly in the autumn and winter. It's recommended not to use the bottom-up method of submersion due to the risk of root rot.
  • Rinse the foliage under a shower once a month, or introduce a humidity tray while the heaters are operating to downplay the risk of dry air. This species of Ficus can deal with average room humidity very well though.
  • Fertilise the soil every two to four weeks with a 'Houseplant' labelled feed, depending on the season.
  • Repot every two years, using a well-draining potting mix, such as 'Houseplant' compost. Be sure to respect the roots as transplant shock is a big issue that may result in death.
  • Keep an eye out for Spider Mites that'll locate themselves along the ridges of the under-leaves.




Location & Light - 🔸🔸

Perfecting the amount of light an African Fig receives is crucial for a long-lasting specimen. During the spring and summer, be sure to provide a brightly lit spot away from any direct light. Excessive exposure during this time will negatively affect the plant in the likes of sun scorch and dehydration. Once the autumn kicks in, move the specimen slightly closer to the window, so that it includes an hour or two of direct light per day to get it through the dormancy period, lasting until the following spring. In terms of a location, we'd recommend placing yours within two metres of a window, in a semi-shaded conservatory or by a Juliette window-door. 


Water - 🔸🔸

Allow a third of the soil to dry out between irrigations during the spring and summer, reducing this further through the colder months. Always use lukewarm water, and if you choose to use tap water, allow it to stand for at least 24hrs before application. African Figs tend to be quite sensitive to temperature change, so pouring cold tap water immediately into the pot will cause nothing but grief in the likes of damaged roots. Under-watering symptoms include grey or yellowing leaves, yellow spots and stunted or deformed growth. Never allow the soil to thoroughly dry out for extended periods, especially in hot spells, as failure to do so could result in distorted growth. Over-watering symptoms include yellowing lower leaves, rotten plant sections and a softened stem. These issues are usually due to too little light or heat, too much water in between waterings, over-potting your specimen, or standing water beneath the pot.


Humidity - 🔸🔸

Average room humidity is enough to satisfy this plant, as long as you don't live in an overly-dry climate. Never situate it within a few metres of an operating radiator due to the enriched chance of browning leaf-tips. If you are indeed worried about dry air, create a humidity tray to provide a moist and stable environment for your plant, which will also have the added benefit of slowing the rates of drying soil!


Fertilisation - 🔸🔸

Feed at fortnightly intervals during the growing period and monthly in winter, using a 'Houseplant' labelled fertiliser. Never directly use a 'ready to pour' feed without a pre-water beforehand, as the combination of dry soil and fine chemicals will result in root-burn. It's important to keep your plant well-fed throughout the year, as this will directly govern the health of the plant and its foliage!




Common Issues with African Figs

A big issue with African Figs is under-watering. As they require a loose potting-mix, weak irrigations will not penetrate the soil enough to retain the moisture. Typical under-watering symptoms include stunted growth, yellowed lower leaves and crispy patches developing on the foliage. These symptoms are typically caused by an array of different issues, with forgetfulness, too much sunlight or heat, or a much-needed transplant being the usual culprits.

Root rot is another common issue with specimens sat in too moist or waterlogged soil for long periods. Symptoms include rapidly yellowing leaves, stunted growth and a rotten brown base. Take the plant out of the pot and inspect health below the soil line. If the roots sport a yellow tinge, you're good to go, but if they're brown and mushy, action must be taken immediately. More information about addressing root rot can be found on this link.

Yellowing lower leaves (closest to soil) are a clear sign of over-watering, usually caused by too little light. Although Ficus can just about do well in a shaded environment, the frequency of irrigations must be reduced to counteract the chance of root rot. People don't realise that a plant's root system needs access to oxygen too; when soil is watered, the air will travel upwards and out of the potting mix. A lack of available oxygen for the roots will cause them to subsequently breakdown over the oncoming days. Click on this link to learn more about root rot and how to address it.

Always use lukewarm water, and if you choose to use tap water, allow it to stand for at least 24hrs before application. This species tends to be quite sensitive to temperature change, so pouring cold tap water immediately into the pot will not only add fluoride into the soil, but it could even cause yellowed leaf-edges over time.

Curled leaves and brown leaf-edges are the result of too little water and over-exposure to the sun. African Figs are best located in bright, indirect settings, and those that haven't acclimatised to the harsh rays will show signs of sun-scorch and environmental shock. A splash of winter sunlight is acceptable as long as the soil moisture is regularly observed, with complete avoidance once summer comes along.

Spider Mites are small, near-transparent critters, that'll slowly suck out the chlorophyll out of the leaves. Have a check under the leaves, most notably along the midrib, for small webs and gritty yellow bumps.

Too low humidity can cause browning tips with yellow halos on juvenile leaves. Although this won't kill your specimen, you may want to increase the local moisture to prevent the new growth from adopting these symptoms. Mist or rinse the foliage from time to time and create a humidity tray while the heaters are active to create a stable environment. The browning of leaf-tips on older leaves is wholly natural and is the product of extensive photosynthesis during its life.

Never allow temperatures to dip below 15ºC (59ºF) as irreversible damage will occur in the likes of yellow foliage and weakened health. When this happens, remove the severely affected areas and immediately improve growing conditions - never cut through softened yellow growth, and only around brown, crispy squares. As rehabilitation can take several months because of its slow-growing nature, be sure to provide a stable location with better growing conditions to speed this process.

The yellow spots that form along the outer edges of the leaves are called cystoliths; they are entirely harmless to your African Fig and will form once the leaf hardens & matures.

Lower leaf loss is a common and significant issue among gardeners. This unfortunate phenomenon could be a product of several different problems, most notably being dark locations, water-related abuse or environmental shock. Introduce the plant to a more well-lit area with a splash of off-peak sunlight; if caught in time, the leaf loss should stop within a week. If you feel that your watering habits aren't up to scratch, familiarise yourself with our care tips provided at the top of this article. It's always best to under-water an African Fig than over-do it, purely on its poor ability to endure continued sogginess. The final culprit could be down to a sudden relocation; if you've recently purchased the specimen, the chances are it is still acclimatising to the new environment. Although this shouldn't happen, a vastly different setting will cause sudden foliage loss and stunted growth. You'll have two options of either waiting it out or presenting a more Ficus-friendly environment, mentioned in the 'Location & Light' section.

Origins 

Ficus cyathistipula was described by Otto Warburg in 1894, who used the specific epithet, cyathistipula, in reference to the blue-sheen on its foliage. The species has a large distribution across central Africa, ranging from South Sudan to Gabon. 

 

The Distribution of Ficus cyathistipula.


Temperature

15° - 26°C   (59° - 80°F)
H1a  (Hardiness Zone 13)  - Must be grown indoors or under glass all year round. Never allow temperatures to dip below 15℃, or situate it near to a cold draught as permanent damage will occur in the likes of leaf loss and blackened growths. 


Spread

Up to 2m in height and 1m in width when grown indoors. The ultimate height will take between 5 - 10 years to achieve, with 10cm of growth per season.


Pruning & Maintenance

Remove yellow or dying leaves, and plant debris to encourage better-growing conditions. While pruning, always use clean scissors or shears to reduce the chance of bacterial and fungal diseases. Never cut through yellowed tissue as this may cause further damage in the likes of diseases or bacterial infections. Remember to make clean incisions as too-damaged wounds may shock the plant, causing weakened growth and a decline in health.


Propagation

Via Seed or Stem Cuttings (Difficult).

Stem & Eye Cuttings (Moderate) - This method of propagation is troublesome without the aid of bottom-heat and a controlled environment. Choose the healthiest, most established stems that are wooded, yet still juvenile enough to bend slightly, being just thicker than a pencil. Each cutting should only have ONE leaf, and a small portion of the stem to either side of the node. Cut directly below a node using a clean knife to reduce bacteria count. Situate the cutting into moist 'Houseplant' compost, with the only the leaf sticking out of the soil. 'Blackleg' can occur when the bottom wound becomes infected, resulting in propagation failure - typically caused by water-logging or a too-damaged wound. Maintain bright light and evenly moist soil with the avoidance of direct sunlight or cold draughts. Wrap the pot (& foliage) in a transparent bag or within a miniature greenhouse, and provide bottom hear of temperatures above 18°C (54°F). Remove the bag and place into individual 7cm (3 inches) pots once the second new leaf emerges. Follow the same care routines, as mentioned in the article's top half. This method will take up to five months, so patience and the correct environment are paramount for success!


Flowers

African Figs inflorescences consist of white flowers developing in early springtime that can vary in size. This period will last up to several weeks and will from berries if pollination is successful. Unfortunately, all Ficus species are highly unlikely to flower if grown domestically, due to the incorrect environmental conditions found in a typical home.


Repotting

Repot every two years in the spring, using a 'Houseplant' labelled compost and the next sized pot with adequate drainage. Hydrate the plant 24hrs before tinkering with the roots to prevent the risk of transplant shock. For those that are situated in a darker location, add a thin layer of small grit in the pot's base to improve drainage and downplay over-watering.

Pests & Diseases

Keep an eye out for mealybugs, aphids, spider mites, scale, thrips, whitefly, blackfly & root mealybugs that'll locate themselves in the cubbyholes and undersides of the leaves, with the exception of the latter in the soil. Common diseases associated with African Figs are root rot, leaf-spot disease, botrytis, rust, powdery mildew & southern blight - click here to learn more about these issues.

If the specimen has dry white crusty patches on its foliage or stem, this is its sap, commonly caused by damage via touch.


Toxicity

This plant is classified as poisonous; if parts of the plants are eaten, vomiting, nausea and a loss of appetite could occur. Consumption of large quantities must be dealt with quickly; acquire medical assistance for further information. The sap can also cause dermatitis and skin allergy to sensitive individuals, so be sure to wear gloves when handling.
