Young monsteras grow solid, heart-shaped leaves. The splits and holes (called fenestrations) come with age, and with light.

  • Bright, indirect light. In a dim corner, new leaves often stay solid.
  • Something to climb. A moss pole or stake helps the plant mature and produce bigger leaves.
  • Patience. Each new leaf tends to be a little larger and more split than the last.

Why the holes at all? Scientists have a few theories. One is that they let a leaf spread over more space and catch the scattered sunlight on the rainforest floor, without growing extra leaf tissue.

Pet note: monsteras are toxic to pets if chewed.
