|My sago palm is coated with white spots. I have heard Asian scale could be a cause. How do I treat this?

|White spots can be a fungal infection called powdery mildew (you can wipe the spots off but they come back in a few days), or the spots can be an insect such as scale or mealybugs. Scale and mealybugs look like raised bumps and you can peel them off the plant but they leave a yellowish spot where they've been attached. Both mealybugs and scales can be controlled by scraping them off with your fingernail or by being dabbed with a cotton swab dipped in rubbing alcohol. There are also chemical controls available at your local garden center. Best wishes with your sago palm.
