It isn't very tall just yet but much further than we ever expected, it's about 2 or 3 feet tall which is really well so far but it has these black spots on the leaves. It looks like some sort of disease but I'm not sure what to do for it and hope that someone on here would know and tell me. I don't have a green thumb so am surprised to see it grow at all and now I don't want it to wilt and die on me! Below is a picture of one of the leaves. Do you know what to do and how to treat it? Thanks so much for the help!!

Wow, do you bring it in in the winter? I have not looked at the picture yet. My first thought was a fungus though. I would make a spray of baking soda and water and spray it. I will look at the picture in just a minute. The websites do not list black spot fungus as a disease of avocados only of roses.

Thanks GG!! When I posted this question, I thought of you!! lol Your name says it all!! Ah, no we just planted it outside last summer and it just took hold some how. Even through all that snow we had, it survived and kept on growing! We're shocked that it took hold as well as it did. I've heard of dormant spray, Bordeaux spray and dormant oil but don't know what they are exactly or where to get it so my question is where do I get those items? I will try the baking soda and water first to see if that works but the other stuff, I'll have to wait for your reply.... Thanks again!!

Where do you live? They are supposed to be tropical. The baking soda spray is probably the only thing that is suitable at this time. Dormant oil and Bordeaux spray are available in garden centers, and you can get them places like Home Depot as well. You use those when the leaves drop off in the winter. Read the labels. One of them has a lot of sulphur in it I think. If your plant is around rose plants, or is losing leaves, clean all the affected stuff up and burn it. Do not put it in your compost. I did not find anything that said avocadoes get black spot fungus, but they get other fungi. The baking soda spray is even used in wheat fields for fungus diseases. Pretty generic. Pick off as many spotted leaves as you can.

I'm in North Carolina, 10 miles south of the Virginia border. Thanks for the info, I will check into it when I go into town again and will try the baking soda spray mixture now in hopes it'll get this fungi or what ever it is. In my mind I'm thinking, if I see spots then there's something wrong. Maybe not and it's a natural thing that happens to some plants? I don't have a green thumb at all so to have something grow from my hands, is a miracle! lol Now what if all the leaves are spotted? Do I remove them all? If I remove all the leaves, will the tree (to be) die? Isn't that how they get their oxygen.... from the leaves?
