I've had a border of dwarf snake plants for years. This spring the outer leaves began to wither. Is it a fungus? What can I do? Someone told me that all the snake plants in South Florida were suffering from some kind of disease. Can you help?

Insects can also weaken plants in this manner. As a precaution, I would examine your snake plants for an insect infestation such as thrips, mealy bugs or spider mites. More information on these pests can be found below:
