Cast Iron Plant Information:

They take well to drying out between watering, and don’t need to be fed often. Cast Iron Plants are really as tough as the name implies.
These plants do extremely well in offices or buildings where they can live away from windows or natural light. They are frequently found in atriums indoors as they pair well with many different plants especially in mixed containers. Cast Iron Plants can be moved outdoors during the summer months and into fully shaded patios or front porches; they appreciate the higher humidity outdoors.

On the other hand, Biotone Starter or Osmocote Indoor/Outdoor is an option as a granular, slow release fertilizer that can be applied while potting and planting.
