A couple weeks ago a ton of huge fires broke out along with some bitter windstorms. Yesterday and 3 days ago a ton of ash and smoke went in the air.

I have 11 bonsai outside and none of them are looking weak or sick except one.

that one is a boxleaf and all of its leaves are shriveling up and falling off. (I hate to say this but I don't like the boxleaf much)

As for my other bonsai, they seem fine but I just wanted to make sure they were okay...
