Help! My Fukien that's about 10 years old (I've had it for 1 year) recently fell all its leaves and now I'm seeing brown fuzz on the ends if the branches. I put the Fukien next to the window and water it only when I feel the soil is dry. I also fertilize once a month. Please let me know what I'm doing wrong and what's the cause of the brown fuzz. Are Fukien also supposed to drop all their leaves once a year?!
