Growing Earth Star in a terrarium
Where to place it
A ground-hugging bromeliad that wants bright indirect light to bring out its pink and bronze stripes — the brightest spot in the terrarium suits it.
Watering & humidity
It draws moisture through its leaves as much as its shallow roots, so keep humidity up and the substrate lightly moist. Happy sealed or open.
Watch out for
It stays put and rarely misbehaves, but poor light flattens the colour to plain green. If it's dull, move it somewhere brighter.
