Cast Iron Plant slow growth

Judge Aspidistra against its own history. A healthy plant may add leaves slowly; losing leaves faster than it replaces them is more useful evidence of a problem than a quiet month.

Give new spears suitable conditions

Move a very dark plant into brighter indirect light. Check beneath the leaves and on stalks for scale. Water after the upper mix dries, empty runoff, and keep the pot close to the root ball’s size.

Feed during active growth at the labeled rate. More fertilizer cannot substitute for light, and a large new pot can leave unused soil wet around a slow root system.
