About Reichenbach's Air Plant
Tillandsia reichenbachii · also called Reichenbach's Air Plant · tropical
Tillandsia reichenbachii is a small to medium epiphytic air plant native to the scrublands and dry forests of southern Bolivia and central Argentina, growing at altitudes of 200–2,000 m. Its leaves are arranged in a distinctive helix giving a starfish or zig-zag appearance, densely clothed in silvery trichomes. It is prized by collectors for its disproportionately large, richly fragrant purple flowers with a white throat that emerge from the centre of the rosette. It is listed as non-toxic to cats and dogs by the ASPCA.
Preferred mix: No soil — mount on cork bark, driftwood, or display on a decorative stand
Watch for — Root and basal rot: Overwatering or poor air circulation causes blackening at the base of the zig-zag leaf arrangement; remove affected tissue with sterile scissors, allow to dry, and reduce watering frequency.
Why reichenbach's air plant needs this mix
Reichenbach's Air Plant grows on air — it has almost no functional root system for feeding, so it is never planted in soil at all.
- Reichenbach's Air Plant absorbs moisture and nutrients through specialised scales on its leaves, so a pot of soil does nothing useful and only traps damaging moisture against its base.
- Its few roots exist mainly to anchor it to bark or rock — they are not feeding roots and rot quickly if buried.
- Free air movement is essential: it must dry within a few hours of every watering or the centre rots.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons reichenbach's air plant struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Potting reichenbach's air plant in soil or packing moss around its base is the classic killer — the crown stays wet and goes black and mushy from the inside.
- Sitting it in a closed terrarium or sealed glass globe with no airflow has the same effect more slowly.
- Glued-onto-a-shell ornaments trap water under the base and rot it; if you have one, prise it off.
Planting reichenbach's air plant in any kind of soil or substrate, or displaying it somewhere it cannot dry out within hours of watering.
pH — does it matter for reichenbach's air plant?
pH is irrelevant for reichenbach's air plant — there is no soil. What matters is water quality: use rain or filtered water, as it is sensitive to tap-water minerals.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
There is no mix to buy or make for reichenbach's air plant. "DIY vs bagged" does not apply — instead invest in a mount, wire or fishing line and a bright, airy spot.
Drainage and the pot
Drainage means airflow here: after soaking or misting, turn reichenbach's air plant upside down to shed water from its centre and let it dry fully before returning it to its display.
There is nothing to repot. Simply re-mount reichenbach's air plant if it outgrows its slab, and never wrap its base in moss that stays wet. When the time comes, our repotting guide for reichenbach's air plant covers the timing and technique step by step.
