How do you encourage fenestration in Monstera?

Answered by Robert Dupre

To encourage fenestration in Monstera plants, one effective method is to trim off the older, smaller leaves that emerge from the base of the plant. This pruning technique helps redirect the plant’s energy towards producing larger leaves with holes, promoting fenestration.

When Monsteras reach a size of around three feet, they are typically mature enough to start developing fenestrated leaves. These are the iconic leaves with the signature holes that Monstera plants are known for. By removing the smaller, older leaves, you create space and allow the plant to focus its resources on growing new leaves with larger holes.

To begin, carefully inspect your Monstera plant and identify the older leaves that are smaller in size and lack fenestration. These are usually located towards the base of the plant. Use sharp, clean pruning shears or scissors to trim these leaves off at the base, making sure not to damage any healthy parts of the plant.

It’s important to note that you should only remove the older, smaller leaves and not the newer leaves that are already showing signs of fenestration. These newer leaves are still developing and have the potential to grow larger and develop more intricate patterns of holes.

After trimming off the older leaves, you may notice that the plant’s energy is redirected towards the growth of larger leaves with fenestration. This process may take some time, as new leaves need to emerge and mature. Be patient and allow the plant to adjust to the pruning.

In addition to pruning, there are a few other factors that can contribute to encouraging fenestration in Monstera plants. Providing adequate sunlight is crucial, as Monsteras thrive in bright, indirect light. Placing the plant near a window or using artificial grow lights can help ensure it receives sufficient light for healthy growth.

Proper watering is also important. Monsteras prefer slightly moist soil but can be prone to root rot if overwatered. Allow the top inch or two of soil to dry out before watering again, and make sure the pot has good drainage.

Lastly, providing a supportive structure such as a moss pole or trellis can encourage upward growth and larger leaf development. Monsteras are natural climbers, and having a structure to cling to can help them reach their full growth potential.

In conclusion, to encourage fenestration in Monstera plants, trimming off the older, smaller leaves from the base of the plant is a helpful technique. This allows the plant to focus its energy on producing larger leaves with holes. Additionally, providing adequate sunlight, proper watering, and a supportive structure can further promote healthy growth and fenestration. Remember to be patient as fenestration takes time, but with proper care, your Monstera will eventually showcase its stunning fenestrated leaves.
