white powdery substance on mediterranean fan palm

We have Mediterranean palms that are covered with a white substance in the middle where all the new growth is. The new fronds have this substance on their main stalk too. What to do? These plants were planted 1 1/2 yrs ago. They’re approx 4-5 ft tall. Thanks.

It is probably powdery mildew. You can treat it with either a chemical fungicide or neem oil. Both should be available at any store that sells gardening supplies. This article will help:
