H E double hockey sticks - with my crooked nose that tree looks straight to me! The algae isn't going away, just going dormant. Next time lots of rain for a period of time - it'll green up again. As I'm just a newbie with figs and only have one "for sure" living tree, I won't know for certain whether it would affect a fig or not. I would doubt that it would - practically all my trees and woody plants have the algae, well and including the front awning, the brick in some places, the dog house, a retired bee hive, deck rails, etc...... Lots of shade, lots of winter and spring rain and dampness, lots of summer humidity, and so many trees don't have the air circulation that more open places have. In fact part of my yard is in so much shade and clayey soil, much of the green "grass" in the spring is moss. I've thought about doing a moss garden, but the hot dry summers and fall would cause me to have to irrigate more than I would want to pay for.
