Congo green Philodendron
The few leaves on my Green Congo Phildendron are spotted. Months ago I made the mistake of spraying it daily along with my Bismarck Palm. How do I bring it back to health?

I would avoid getting water on the leaves when watering.
Make sure the plant soil dries slightly between watering. Make sure the plant has good air flow around it to help avoid fungal diseases.
