I have a sago palm that has developed brown, round, dry spots. I live in Kansas City, so I winter the plant inside. The first year it did fine, but this past winter it developed round, 3-dimensional brown spots. It is still getting new growth, also getting the brown spots, but I've lost most of the old leaves. I've taken a glove and wiped off the spots (they come off very easily) only to have them return. Any hope to save it?
