Cast Iron Plant Care & Growing Guide

1. Light Requirement

It can grow indoors in low light.  You do not want to put it in direct sunlight as the rays of the sun can burn the leaves, turning them brown.

2. Water

Although it is a plant that is not finicky about regular watering, in very dry periods it will need to have plenty of water.  During its growing season, which is spring and summer, the Cast Iron plant should be watered regularly to help establish their extensive root system.  After the roots are established, you can reduce the watering schedule.

One unique thing about the Cast Iron plant, when grown indoors , is that you should water it with filtered water.  The minerals from regular tap water can accumulate in the tips of the leaves and if you use soft water, it can stunt the growth of the plant.
