Top Tips & Info

  • Care Difficulty - Easy
  • Bright, indirect light is advised as excessive periods in the intense sun will quickly lead to sun-scorch and dehydration. Keep the specimen slightly under-watered with those situated in darker environments. 
  • Maintain a good level of soil moisture by allowing the top third to dry out in between waters.
  • Supplement using a 'Houseplant Feed' every two to four weeks, depending on the season.
  • Each individual plant will only flower once, so you'll have to wait until the 'pups' (basal offsets) reach maturity for another bloom. You can even separate the 'pups' in the spring once they surpass 5cm in length.
  • Repot every three years using a Houseplant potting mix; this is the perfect time for propagation and a quick check on the root/soil health.
  • This group of Bromeliad is an excellent choice for terrariums due to its compact-nature and uncomplicated care requirements.




Location & Light - 🔸🔸

Bright, indirect light is best. Prolonged droughts or exposure to the sun will quickly result in pale foliage, stunted growth and crisping foliage - if it's too hot for a chocolate bar, it'll be too hot for the plant, too! Despite the stigma around ground-baring Tillandsia doing well in dark environments, you must reduce the amount of water somewhat to counteract the longer soil-drying times. If the central foliage begins to rot with mould on the soil, it could be a case of excess moisture settling on its leaves and over-watering.


Water - 🔸🔸

Allow the top third of the soil to dry out between waters, reducing this further in the autumn and winter. Under-watering symptoms include pale leaves, brown leaf patches, sunken foliage and crisping flowers; these issues are typically caused by intense sun or heat, being potbound, or pure forgetfulness. Over-watering symptoms include a rotten stem with yellowing leaves, flower collapse and 'pup' death. If this occurs AFTER the flowers have elapsed, this is a natural response after unsuccessful reproduction. For those that haven't flowered, possible reasons for the decline are too little light or heat, excess moisture within its foliage and a lack of drainage.


Humidity - 🔸🔸🔸

Although Tillandsia will accept average room humidity, introduce a pebble tray to provide a moist and stable environment for your plant. If the surrounding saturation is too low or the heat too high, its leaf-tips may start to brown over and curl, especially in direct sunlight. Hose the foliage down from time to time to hydrate the leaves and keep the dust levels down. Those situated in a terrarium won't require misting or use of a pebble tray due to the proximity of other plants and higher levels of transpiration.


Fertilisation - 🔸

Fertilise every two weeks in the growing period with either a 'houseplant' labelled feed or a 'bromeliad' fertiliser, reducing this to monthly in the autumn and winter.




Common Issues with Tillandsia

Plant death shortly after the flowering process is a natural and prevalent issue among growers. If you're looking to preserve the specimen for several years after the blooming period, be sure to provide a bright location and keep it under-watered with no moisture accumulating in its central 'well'. As over-watering and shady spots are the usual killers with recently-flowered individuals, keeping the foliage and soil on the drier side will allow it to enter its dormancy before developing basal offsets between its lower leaves. You can either leave the plant as it is or separate the offsets (pups) to grow in their own pots. Scroll down to 'Propagation' for more avid regarding this matter.

Alternatively, a lack of blooms from a non-flowered specimen is caused by an insufficient dormancy period, where the temperatures are kept more or less the same over the year. Reduce the temperature by a couple of degrees over the autumn and winter months, along with fewer irrigations to ensure a well-spent dormancy.

Yellowing older leaves (closest to soil) and crown rot are a clear sign of over-watering, usually caused by too little light. Although Tillandsia 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.

Curled leaves and brown leaf-edges are the result of too little water and over-exposure to the sun. Tillandsia 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 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.




Origins

Although Tillandsia is mostly epiphytic, there are fifteen species that grow terrestrially and therefore require different care compared to their airborne counterparts. The genus was first penned in 1753 by Carl Linnaeus, honouring Dr E. Tillandz, a Swedish botanist and physician during mid-17th-century. Out of the 650 species of Tillandsia, around 630 are classified as epiphytic and are divided into seven subgenera - Allardtia, Anoplophytum, Diaphoranthema, Phytarrhiza, Pseudalcantarea, Pseudo-Catopsis & Tillandsia.


The Distribution of Tillandsia


Temperature 

12° - 30°C   (54 - 86°F)
H1a (Hardiness Zone 13) - This plant should ideally be grown indoors or under glass all year round. Never allow temperatures to dip below 12℃ or permanent damage may occur in the likes of flower loss, stunted growth and yellowed leaves.


Spread

Most species will only reach up to 15cm in height and width. Maturity can take around four years to achieve, with 'pups' achieving this stage in around 6 years.


Pruning & Maintenance

Remove yellow or dying leaves, and plant debris to encourage better-growing conditions. While pruning, always use clean utensils 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.

Remove the flower stalk close to the plant's well once it begins to wilt, keeping the well dry from there on in. If the open tissue from the stalk's base remains submerged in water, it could result in rot that may spread to the rest of the plant if untreated. 


Propagation

Via Seed or 'Pup' Propagation.

Basal Offset Division (Easy) - Your plant will produce several basal offsets that can be separated once they have a sufficient root system and surpass the mother plant's height by half. If possible, water the soil 24hrs before the main event to reduce the risk of transplant shock, when its dry root systems are over-touched. Take the plant out of its pot and place your fingers close to the nodal junction - compost may have to be removed for better access. Push the chosen offset downwards until you hear a snap. Separate the foliage and its root system away from the mother plant, mentally noting the high risk of damage. Transplant in the appropriate sized pot with a fresh batch of houseplant-labelled compost. Maintain evenly moist soil and situate it in a bright, indirect location away from any direct sunlight. After four weeks, treat it like a healthy specimen, following the care tips above!


Flowers

The individual specimen will only flower once, but as mentioned above, pups will form at the base of the plant that'll eventually flower. The bloom can be up to 40cm in length and can last up to three months in the spring or summer. Colours include: red, yellow, green, brown, purple or pink that are arranged in either a zigzag, spade or pole-shaped inflorescence.


Repotting

Although it isn't entirely necessary, you can transplant it every few years in the spring using a houseplant-labelled compost with the next sized pot. 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 an extra splash of perlite in the pot's base to improve drainage and downplay over-watering.

Pests & Diseases

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


Toxicity

Not known to be poisonous when consumed by pets and humans. If large quantities are eaten, it may result in vomiting, nausea and a loss of appetite. Although the leaves may look delicate from online pictures, its foliage and flowers can be very sharp, acting like small Swiss-army knives.
