Q.

My Swiss cheese philodendron has black crusty areas on new growth?

Zone 98122 | Kristin f added on July 11, 2019 | Answered

I just bought my beautiful plant and it looks healthy except for black crusty holes forming on fresh new growth. I have it near a skylight in a med light room. Just got the plant last week and noticed fruit flies around it too. I let it dry out between watering a. Any ideas?

These do appear to be similar to Philodendron but they are Monstera! They have slightly different care than the Philodendron.

This appears to be a fungal infection. Perhaps it takes too long to dry out between watering?

You will need to apply a fungicide, and make sure that there is plenty of ventilation to help it dry between waterings, as fast as possible.
