Black Spots on Leaves
I have an indoor ficus that is about 2 years old. I noticed the leaves were falling at a fast pace and there were spots on them. I have attached a picture. Do you know what the pest is and what I should treat with? Thank you!
This looks like a fungal infection, which can happen if the tree remains moist for too long. They tend to be mildly drought tolerant, and will not like to stay wet for very long. You can add wettable sulfur and dolomitic lime to the soil, to help cure the pest, and restore the soil to a more suitable condition.
