Mr. Barr,
Could you explain why some individual leaves are able to resist algae infestation on the same plant? I can guess that the obvious response is that some leaves are healthier than others but I would like to understand what really constitutes a healthy leaf.
Some leaves continue to develop much more algae repeatedly and much more rapidly no matter how often it is cleaned. What is this leaf missing to prevent the spores from becoming attached? What is the attachment method an adhesive or hook? Does the algae actually pull nutrients from the leaf, and is this therefore why it is better to prune the leaf rather than to continnually try to remove the it's algae coating?
Cheers,
