What is Fenestration?

Fenestrations are the “holes” in your plants. Tropical plant species, such as Monsteras, Philodendrons, and Pothos can have them.

The theory is that they have fenestrations because as they mature, they climb and vine whatever is near them to reach the sky. As they are doing this, they are growing really big and the bottom leaves don’t get enough sunlight. So the newer mature leaves start to fenestrate.

Many plant species have different fenestration patterns if they are let to climb. For example, Cebu Blue Pothos and Golden Pothos start to split their leaves beautifully as they mature and the Skeleton key Pothos starts to make a key-shaped leaf as it grows upward.
