How to Grow and Care for Air Plants (Grey Tillandsia) Indoors


Air Plant, Tillandsia, Grey Tillandsia

Botanical name: Tillandsia spp
Family: Bromeliaceae
Sufamily: Tillandsidoeae

Description

Air Plants (Grey Tillandsia) are unique plants that do not need to be planted in a potting medium as furry scales on their foliage take up water from humid air and obtain nutrients from air-borne dust and moisture.

Grey Tillandsia literally live on air and hence the common name "Air Plants". These plants can be displayed by sticking them on coral, shells, drift wood, hanging them and many other ways.

Flower

When Air Plants bloom, the leaves around the flowers change color and provide a lasting bright display, but the blooms themselves last only a few days.

Once the flower-head fades, the rosette of leaves in the Air Plant begins to die and is replaced by offsets (pups) at the base.

Types (Varieties)

The most widespread species of Air Plants is Tillandsia usneoides (Spanish Moss) which can be found hanging on trees throughout the warm tropical forests.

Tillandsia caput-medusae is one of the most popular Air Plants whose thick and twisted leaves arise from a bulbous base and has very showy red bracts and blue flowers.

Another common variety is Tillandsia ionatha which forms a compact rosette of arching silvery leaves and grows only a couple of inches tall. Its inner foliage turns red when the stalkless violet flowers appear.

Tillandsia juncea is a long-leaved species whose rush-like foliage spreads outwards and a single flower-stalk bears the terminal blooms well above the heart of the plant.

Tillandsia argentea is a silvery species whose short leaves spread untidily outwards as the plant develops.

Is Air Plant toxic?

Air Plants (Grey Tillandsia) are non-toxic to humans and pets. The Air Plants are safe to grow indoors.

Air Plants Care Indoors

Air Plants (Grey Tillandsia) require bright light but away from direct sunlight, warm and humid conditions coupled with fortnightly feeding during the growing season.

Grey Tillandsia require pruning to keep them neat as well as create enough space of the growth of pups. Keep reading for more on these growing conditions and how to provide them.

Light Requirements

Air Plants grows best in bright light but away from direct sunlight to prevent scorching.

Rotate the plant regularly to ensure that the plant receives light on all sides for even growth.

Grey Tillandsia can also grow under a grow light where the natural lighting is not adequate.

Watering

Watering Air Plants grown in a glass container

Ensure that the container has an opening for proper air circulation to prevent rotting and disease infestations.

Water the Air Plant by daily misting of the leaves during the growing season. Reduce misting to 2-3 times weekly during the cold season.

Watering Air Plants that are in the open

Water the Air Plant by dunking; dip the entire plant into a container of water and allow some time for the plant to absorb the water.

Dunk the plant 2-3 times per week in the growing season and reduce in the cold season.

Shake off excess water and hang it upside-down to ensure no water remains standing in the center as it can lead to rotting.

To ensure that the plant dries out quickly to avoid crown-rot, water it in the morning so that it can dry out during the day when temperatures are higher than at night.

Use tepid, chlorine-free water like rain water to water Grey Tillandsia. Do not use chlorinated water as they are sensitive to chlorine and may cause it die.

Do not use distilled water as the distillation process removes all the nutrients required for growth.

Make sure that there is good air circulation for the Air Plants to prevent pest and disease infestations.

Temperature and Humidity

The best temperature for growing Air Plant indoors is an average warmth with a minimum of 100C. However, to bring the plant to flower may require temperatures above 260C.

Grey Tillandsia require a humid enviroment as is present in their natural environment. If the humidity is too low, the plant will respond with brown leaf tips.

To elevate humidity, mist it more regularly or use a cool mist humidifier.

Ascertain that there is good air circulation to discourage pests and diseases infestation.

Fertilizer

Feed the Air Plant with a liquid fertilizer (foliar feed) every 2 weeks during the growing season to enhance growth.

Do not use a fertilizer that contains urea nitrogen as Grey Tillandsia cannot use urea nitrogen.

Do not feed during the cold season as growth is minimal and it may cause fertilizer burn and death of the plant.

Pruning

Pruning Air Plant involves removal of dead leaves to keep the plant neat and to allow adequate room for the new plants to grow.

Remove the dead foliage by cutting at the base with a clean knife or a pair of scissors.

Snip off the dry, brown leaf tips with sharp scissors. Cut them at an angle so that they can blend in naturally with the rest of the leaves.

Propagation

Air Plants (Grey Tillandsia) are propagated from offsets (pups) appearing at the base of the plant.

When the offset is several months old or 1/3 to 1/2 the height of mother plant, cut it away from the mother plant.

Confirm that the offset has some roots attached for faster establishment. Display the offset on its own and begin routine care.

Air Plants Problems

Air Plants (Grey Tillandsia) problems include slow growth, plant death, rotting, brown leaf tips. diseases and pests among others. Keep reading for more on these problems, their remedies and solutions.

Slow growth and pale leaves

Air Plant slow growth and pale leaves are due to inadequate light as they grow best in bright light away from direct sunlight.

Position the Grey Tillandsia in a brighter spot where it will receive bright light away from direct sunshine or instal a grow light if the natural lighting is not sufficient.

Brown leaf tips

Air Plant brown leaf tips are due to three possible causes. One possible cause is underwatering. Water the plant more regularly and ensure the entire plant is thoroughly soaked.

The second possible cause of brown leaf tips in Grey Tillandsia is overfeeding. Reduce either frequency of feeding or quantity of feed as they are slow growers and require very minimal feeding.

The third possible cause of brown leaf tips in Grey Tillandsia is too low humidity. Mist the plant more regularly or grow the plant in a bathroom and other moist areas in the home.

Brown or grey slimy crown and roots

Air Plant brown or grey slimy crown and roots is an indication of rotting due to excess water standing at the base of the crown.

Trim the rotten roots but if the crown is rotten, discard the plant as it is too far gone and can not be saved.

Always drain excess water from the crown after watering or wipe it dry with a soft cloth.

Plant dying

Air Plant dying is due to two reasons. If it has not flowered, the cause of death is crown and stem-rot disease due to water sitting in the crown.

If the Grey Tillandsia has flowered then rotting and death of rosette which bore flower-stalk is natural to give room for the new plants.

Remove the dead foliage by cutting at the base with a clean knife or a pair of scissors.

Whitish leaves even after watering

Whitish leaves even after watering in Air Plants is caused by low air humidity as they require a humid environment to thrive.

Mist the plant more regularly or place it in a glass bowl and keep a wet sponge inside to increase humidity. A cool mist humidifier is also a good option to raise humidity for the Grey Tillandsia.

Leaves reddish, dry and brittle

Air Plant leaves reddish, dry and brittle are due to exposure to direct sunlight. Move the plant to a shadier spot or shield it from direct sunlight.

Pests

Common pests in Air Plants are Scales and Mealy Bugs. Isolate the affected plant to prevent spread to other houseplants and treat it appropriately for the pests.

To discourage pests infestation, raise humidity by more regular misting or use a cool mist humidifier.
