The black spots on the leaves of your lemon tree could be a sign of several potential issues Based on the images it appears that the spots might be caused by either a fungal infection such as sooty mold or by a pest infestation Here’s what you can do
Check for pests Black spots especially combined with yellowing leaves can indicate that pests like aphids scale or whiteflies are present These pests leave behind a sticky substance called honeydew which attracts mold and can lead to the black spots you’re seeing Inspect the undersides of the leaves and stems for pests If you find any you can treat them with insecticidal soap or neem oil to eliminate the pests and prevent further damage
If pests aren’t the issue it could be a fungal infection Sooty mold is a common problem when honeydew is present on leaves but other fungal diseases could cause similar symptoms Removing affected leaves and improving air circulation around the plant can help reduce the spread of the fungus If the problem persists you may need to use a fungicide to treat the infection
Make sure the tree is getting enough sunlight and isn’t being overwatered as both of these factors can weaken the plant and make it more susceptible to infections
