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.

Any all purpose, foliage fertilizer will work for Cast Iron Plants. Indoor houseplant fertilizers fall into two groups: water soluble, liquid quick release, and granular, slow release fertilizers. Jack’s Classic Indoor plant food works well as a powder, quick release fertilizer that is mixed with water to quickly provide nutrients to a plant that has been in a container for an extended time. 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. Any type of fertilizer offers nutrients that help plants with the transition to a new environment. We offer a one year warranty on our plants when you purchase Bio-tone at checkout and use it per label instructions. All of these fertilizers may be used when planting Cast Iron Plants.
