Top Tips & Info

  • Care Difficulty - Very easy
  • Provide a bright, indirect location with the absence of direct sun.
  • Allow the soil's top third to dry out in between waters, reducing this in the autumn and winter.
  • Supplement every two to four weeks using a houseplant-labelled feed, depending in the season.
  • Keep an eye out for Spider Mite that'll form webs on the under-leaves of the plant.
  • Repot every three years using a houseplant soil and the next sized pot.
  • Keep an eye out for any loss of pre-existing variegations (patterns), as too-dark locations will cause them to fade & disappear. Settings that are too bright may develop exaggerated variegations with little to no green tissue.




Location & Light - 🔸🔸

Provide a bright, indirect location with minimal sunlight. Those grown in a darker setting will significantly increase the chance of root rot, as well as variegated specimens losing their colourful patterns.

Remember - The amount of light and current season of the year will directly govern the frequencies of waters per month. Specimens placed in shadier areas must be kept on the drier side to life, whereas brighter locations will require more soil moisture to lubricate photosynthesis.


Water - 🔸🔸

Allow the top third of the soil to dry out in between waters, reducing this further in the autumn and winter. For those situated in shadier environments, allow around half of the soil dry out in between waters to counteract the chance of over-watering, especially in the winter months. Under-watering symptoms include stunted growth, yellowing leaves or sudden flower loss. These issues could be a product of many elements; however, too much sunlight or forgetfulness are usually the culprits. Over-watering symptoms include the yellowing or loss of leaves, stunted growth or a rotten base. These problems are typically familiar with either too little light or heat or overly soggy soil; if you feel that root rot is the case, be sure to click on this link for more info.


Humidity - 🔸🔸

Average room humidity is excellent for Devil's Ivy, as over-misting may cause the development of powdery mildew or botrytis. At monthly intervals, perform a gentle hose-down to hydrate its leaves and reduce the number of dust particles resting on its foliage.


Fertilisation - 🔸🔸

Supplement fortnightly during spring and summer, and monthly during in the colder months to replicate its dormancy period. Directly applying a 'ready to pour' feed into the soil without a pre-water beforehand will burn the roots, causing yellowed leaves and stunted growth.

Although a general plant fertiliser will still do the job, we'd recommend using a houseplant-labelled product as it'll provide the thirteen primary nutrients for good quality growth.




Common Issues with Devil's Ivy

A loss of variegations is caused by too little light. Although Devil's Ivy is an excellent choice for shady locations, it'll come at the cost of its variegations. Move the plant into a brighter area with minimal direct sunlight to allow the variegations to appear on the new growth. If you aren't entirely displeased about the loss, simply skip this step. Alternatively, extreme variegations that hinder the plant from developing chlorophyll (green pigmentation) is typically caused by too much sunlight.

Root rot is a 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.

Pests could arise at any time, with infestations starting from the original nursery or via contamination in your home. With Devil's Ivy, Spider Mite and Mealybugs tend to be the usual inhabitants, with the first being minute and almost transparent, roaming the leaves in search of chlorophyll and a site to hide its eggs. The latter, however, will stand out much more, with white cottony webs developing across the foliage and stems. Thoroughly check the plant's cubbyholes before giving it the all-clear, or click on the appropriate links to learn more about eradicating these issues.

Always use lukewarm water, and if you choose to use tap water, allow it to stand for at least 24hrs before application. Devil's Ivy tend 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 lead to yellowed leaves over time!

Curled leaves and brown leaf-edges are the result of too little water and over-exposure to the sun. Devil's Ivy 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.

Too low humidity can cause browning leaf tips with yellow halos. 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 whilst the heaters are active to create a stable environment for your specimen.

The browning of each cataphyll shouldn't of be a concern, as it's a wholly natural process which affects all specimens across the world. Remove the brown section once it becomes dry and crispy, using your hands to peel back the browned tissue and improve its overall appearance.

Yellowing lower leaves (closest to soil) are a clear sign of over-watering, usually caused by too little light. Although they can do well in darker locations, 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 accessible 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, and always feel the pot's weight for confirmation (heaviness = good soil moisture, & vice versa).




Allowing Devil's Ivy to climb up walls or moss poles is an excellent way to promote longer vines. These sticky-pad clips can be found at local hardware stores for relatively cheap prices!


Origins

Devil's Ivy forms part of the Arecaceæ family that hold genera such as Spathiphyllum (Peace Lilies), Alocasia and Zamioculcas (ZZ plants). It has had multiple names since being formally classified in 1880, including Pothos, Raphidophora aurea, and finally into the genus of EpipremnumThe species is reluctant to bloom, with the last known natural flower being recorded in 1962, the same year in which its name transitioned from Pothos to Rhapidophora. Despite its name change, the new placement in this genus didn't last long; additional inspection of its flowers strongly indicated the similarities between another genus, Epipremnum, and was subsequently replaced a short while after. The nickname, Devil's Ivy, refers its ability to remain green even in intensively dark locations, as well as its hard-to-kill ethics. 'Scindapsus' was mainly used in 1908 and derived from the Ancient Greek instrument, skindapsos - a four-stringed instrument struck by fingers. The two most popular variants of the genus, the E. pictum & E. aurea, originate from the Society Islands and can be translated from Greek as 'to paint' and from Latin meaning 'gold or golden', respectively.


The Distribution of Devil's Ivy


Temperature

12° - 30°C   (54° - 86°F)
H1b  (Hardiness Zone 12)  - Can be grown outdoors during the summer in a sheltered location with temperatures above 12℃  (54℉),  but is fine to remain indoors, too. If you decide to bring this plant outdoors, don't allow it to endure more than an hour of direct sunlight a day as it may result in sun-scorch. Regularly keep an eye out for pests, especially when re-introducing it back indoors.


Spread

Up to 8m in height and 3m in width, when given a structure to climb up; the ultimate height will take between 5 - 8 years to achieve. Devil's Ivy that naturally grow in the wild can reach heights of up to twenty metres; however, smaller root systems and less favourable growing conditions will significantly reduce the overall height.


Pruning

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.

Although the aerial roots aren't exactly appealing, do not remove them as it may put stress upon the plant and potentially could weaken it with potential diseases.


Although it'll look messy at first, the vines will slowly branch out to the majority of the wall.  Plant: Scindapsus pictus 'Argyraeus'


Propagation

Via Seed or Vine Cuttings.


Vine Cuttings (Easy)


Nodes - Adventitious roots that'll develop below the nodal junction, to anchor the plant to its host. This is where the cutting will root from.


Water 

  1. Choose the healthiest, most established vines that are wooded, but still juvenile enough to slightly bend. This propagation method can be taken from spring to summer, using between three to six leaves, with the vine being at least 12cm (4.7 inches) in length with two nodes (one for foliar development and the other for root growth). Although more nodes are fine, be sure only to submerge the bottom ones to avoid inappropriate rooting elsewhere, which will be more difficult when it's time for soil placement.
  2. Cut directly below a node using a clean knife to reduce bacteria count. Remove the lower half of the leaves and place the vines into a container of lukewarm water. Be sure to submerge at least one node into the water, or else the root development will be hindered.
  3. The leaves must stay above the waterline, for the prevention of disease.
  4. Replace the water weekly, using lukewarm water to avert shocking the cutting with cold temperatures. 
  5. Once the roots surpass 4cm (2 inches) in length, it's time to pot the cutting.
  6. Choose a potting mix - as long as it has a well-draining nature, most soils are fine. Houseplant compost is best, but a multi-purpose compost with a splash of grit or perlite is acceptable, too.
  7. Use a 7cm (3 inches) pot that has suitable drainage holes - plastic or terracotta are both acceptable in this instance. Try not to over-pot the cuttings - blackleg occurs when the bottom wound becomes infected, typically caused by water-logging or a too-damaged wound. See the last image towards the bottom of the article.
  8. Set the cutting into the compost, keeping the foliage above the soil line.
  9. Avoid direct sunlight and offer good humidity by placing the potted plants into a transparent plastic bag for the first couple of weeks. 
  10. Open the bag every two days for half an hour for the prevention of disease. After a month of being placed in soil, remove it from the bag and follow the care tips provided above.


Soil

  1. Choose the healthiest, most established vines that are wooded, but still juvenile enough to slightly bend. This propagation method can be taken all year round, using two nodes that already house aerial roots (image above). You should only have two nodes so that the lower one is for root development and the other for foliar growth. Remove the lower leaf so that each cutting only has one leaf.
  2. Cut directly below a node using a clean knife to reduce bacteria count. Remove the lower leaf and place the vine into a moist, well-draining potting mix. Houseplant compost is best as it'll include perlite for better air circulation within the soil. 
  3. Use a 5-inch pot that has good drainage holes - plastic or terracotta are both acceptable in this instance. Try not to over-pot the cuttings - blackleg occurs when the bottom wound becomes infected, typically caused by water-logging or a too-damaged wound. See the last image towards the bottom of the article.
  4. Set the cutting into the compost, keeping the foliage above the soil line. Be sure to submerge the lower node into the soil wholly, or else root development will be hindered.
  5. Provide a bright, indirect setting with adequate warmth and the avoidance of direct sunlight nearby radiators. Place the potted cutting into a transparent plastic bag for the first couple of weeks to lock in extra humidity so that the cutting doesn't dry out. Maintain moist, but not soggy, compost throughout this process. 
  6. Open the bag every two days for half an hour for the prevention of disease. After a month of being placed in soil, remove the bag and follow the care tips provided above.



Flowers

It's evidently rare for a Devil's Ivy to flower; the last known flower to bloom in the wild was in 1962. For those that are interested, Devil's Ivy form part of the Araceæ family that typically has a spadix surrounded by a spoon-shaped spathe. The best example of this would be a Peace Lily.


Repotting

Repot every three years in the spring using a houseplant-labelled compost and the next sized pot with adequate drainage. Hydrate the plant 24hrs before the 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, spider mite, scale & thrips that'll locate themselves in the cubbyholes and undersides of the leaves. Typical diseases associated with Devil's Ivy are leaf-spot disease, botrytis & root rot; click here for more information about how to identify and address any of these issues.


Toxicity

This plant is classified as poisonous due to varying concentrations of calcium oxalate crystals found around the plant's body. 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.
