Spots on pothos
I have light brown spots on my pothos leaves. They have slowly increased in number ever since I put my pothos outside last summer. What is wrong with her?
Since your plant was outdoors it very well could be a fungus issue on your plant.
Clip out any leaves with signs of disease by pinching or use a clean garden snip. Clean the tools with alcohol after use to prevent spreading of the fungus.
Make sure the soil is drying between waterings and do not splash water unto the leaves.
Adding some air circulation can help. If the plant is quite full you can also prune out some growth to improve circulation.
If the problem persists use Neem Oil as a treatment. Neem Oil works as both an insecticide an fungicide. It is safe for people and pets.
