Philodendron (genus, Philodendron) is a kind of flowering plant that belongs to the Araceae family. These can be grown as both indoor and outdoor plants. But, they have their problems if not taken care of or if their surrounding environment is unsuitable for the plants. One common problem is white spots on the leaves.
A pest infestation, fungal infection, low lighting conditions, cold temperatures, and poor ventilation are common causes of a philodendron’s white spots. Spray neem oil on your philodendron to keep the pests away, provide sufficient indirect light, and keep them away from cold drafts.
Identifying the problem can seem challenging, but you can fix the problem and cure your philodendron once you identify the issue.
Now let’s discuss the causes of white spots in detail.
What are the causes of White Spots On Philodendron Leaves?
Some reasons or causes of these white spots in the philodendron plants can be:
- Fungal Diseases
- Pest infestation
- Low-temperature issues
- Poor water quality
- Lack of fertilizers
There may be more reasons behind white spots other than those mentioned above. But these are some of the widespread problems behind the white spots in philodendrons.
Now, let us elaborate on these issues and discuss their treatment.
Fungal diseases cause a variety of symptoms, including white patches or spots on the leaves.
If you notice dusty white spots spreading on your plant, usually on the top of the leaf, it’s probably powdery mildew. Philodendron plants love a humid environment. Unfortunately, so does powdery mildew!

Although powdery mildew is not so dangerous in itself, it can stop leaves from functioning correctly in large amounts. Eventually, this causes weak, slow growth and can even lead to death.
If you notice a small amount of powdery mildew in your plant, simply remove the affected leaf. If the infection is very bad or spreads quickly, several fungicides are available to treat the problem. Always follow the instructions for the particular brand that you buy.
You can guard against powdery mildew by ensuring enough air circulation around your plants and removing fallen leaves from the plant’s container.
Powdery mildew spores can live for a long time so make sure that you clean plant pots before reusing them, and never reuse infected potting mix without treating it with a fungicide first.
Fusarium Leaf Spot
Fusarium leaf spot
Spores spread through the air and land on moisture on the leaves of a plant, then begin to consume the plant and reproduce – causing the symptoms.
The poor watering technique is a common cause of leaf spot diseases. If you get water on the leaves of your plant, you’re giving the spores a chance to make a home.
If possible, always water your plant from underneath. If you need to water it from above, make sure you don’t get water on the leaves!
If you notice a leaf spot, remove the affected leaves immediately. Use a fungicide developed for fusarium leaf spot, and make sure to follow the instructions.
