A very sad lime tree
Fungus looked similar
I was so proud of my little lime tree that came up as a volunteer. A little over a month ago I noticed a growth on the trunk at ground level. I knocked it off and cleaned it up a bit. Two weeks later it was back. Lorena did it again about a week ago but it was too late. Guess I'll have to dig it up soon.
Soap and water and/or nitrogen fertilizer are suggested ways to kill the fungus but the tree was too far gone by the time I hit the Internet. Gonna have to keep a closer eye on the rest of my trees. It also says to completely dispose of the mushroom or it could spread in the yard. All I did was throw it on the compost. Hope I'm not in for trouble.
