I have a problem with the spores on the leather leaf
The spores are naturally occurring and cannot be prevented by the growers (mostly during June - July). You may need to remove the spores just like you have to remove pollen in lilies. We recommend wiping the back side of the frond with a soft paper towel. Any ripe spores should detach from the leaf. If the spores won't release, gently taps the frond.
