Why are my branches turning black?
I've had my kumquat tree for about 2 mo from the store and keep it indoors as we live in zone 2a. I guess I can have it out during the summer?! or not-let me know.. It had a mite of some sort attack it a week ago.. (moving white dots and I found some webbing between two branches. all if which I got rid of with soapy water spray). And now recently it has started losing leaves and I see the branches are turning a dark brown/black color so I've been cutting these branches off in hopes of isolating whatever is killing the branches off but to no avail. Please help!
