I have attached a picture of the problem. This plant was doing fine and was thriving the first few months it was in the basket. It is still putting out new leaves fairly rapidly. However, there are brown and black "blotches" all over some of the leaves. The affected leaves eventually die, turn brown and fall off the plant. It almost looks like mold.

The shields were set on top of spag. moss in a medium sized basket. I was watering it occasionally and read about problems due to over-watering. It has not been watered with a hose in over a month now. But, it has been raining pretty regularly (unusual for this time of year).

Any advice or help is greatly appreciated!!
