Cast iron plant care

Aspidistra elatior

Thirsty’s starting schedule for Cast iron plant: about every 14 days. Check the soil and adjust it to your home.

Watering

Water once the top 2 to 3 inches of soil have dried, let the excess drain away and empty the saucer. Keep it a little drier in winter and take care not to overwater. [1][2][3]

Light

Low to filtered light, such as a north-facing window; keep it out of direct sun, which scorches the leaves. [1][2][3]

Soil and potting

A well-drained potting mix. [1][3]

Pets

Non-toxic to cats and dogs. [4]
