Rotting base from overwatering / waterlogged compost; bleached, shrivelled leaves from direct sun; faded banding from too much shade; mealybugs, scale, mites.
如何解决Earth Star (Cryptanthus)的常见问题？
Water the root zone, not the rosette (there is no central cup); water when the surface starts to dry. Free-draining, humus-rich, slightly acidic mix (e.g. equal peat, bark and coarse sand). Half-strength liquid feed every 2–4 weeks spring to autumn; very sparingly in a closed tank. Older label names may be outdated – many species moved to other genera in 2017.
