Question
I am new to king sago's and am seeing my plant covered in white spots under the foliage, it looks like it was painted. Is this scale or bugs?Do i need to treat it?Otherwise it looks very healthy

Answer
Hi there. Being from NJ,I had to look up King Sago. Never heard of this palm. However,what you have sounds like either scale or aphids.
here is a web site you might try.
