If you live in Florida chances are you have at least one sego palm in your yard. In recent years there seems be a growing problem of “white stuff”, correctly called cycad or aulacaspis scale (Aulacaspis yasumatsui), on these palms. The Sago Palm is really not a palm at all but a type of plant called a cycad. Thus, this cycad scale is very specific to the sego, and a small number of other cycads, and will not spread to palms or other plants. For more info on this click here.
If you have a sego palm, chances are you’re battling cycad scale. Here is a great tip for getting rid of it. First, you must remove all fronds from the sego. The sego may look bald, but it will not harm the plant, and it will grow new fronds. Next pay a visit to your local coffee shop. No, you are not just in need of a drink, but you are after their coffee grounds. You may want to call ahead to ask them to save them for you. Put about 20 lbs of coffee grounds around the base of your infested sego. That’s all there is to it. I have no idea why or how this works but a friend of mine tried this and it worked. At first I was a skeptic, but seeing the palms again today, I must say, I’m a believer.
