fungus damage

Hi all, I just started growing bonsai seriously this past spring. I've read a plethora of posts to this forum that were immensely helpful as I learned the basics, so I'm hoping y'all can help with a more specific issue. I recently moved to San Diego (10b) and, with the new growing space I now...

I purchased my first Bonsai about 2 months ago. Everything seemed great up until two weeks ago. I found what looks like some kind of disease on the stem of my green mound. Multiple areas of the stem seem to be infected. It seems as though it is “bleeding” and there is some disease growing on...

I’m having a few various issues with plants this year. We’ve had a significantly wet and mild spring, which I’m definitely not complaining about, but I think it’s started to rear it’s head this past couple weeks. This may be a variety of things, but I’m struggling to nail down exactly what I...

I picked up this little pagoda Japanese holly at a small local nursery while we were up in North Carolina. They’re very hard to find locally back at home and online they are small sticks in a pot for $30+. I haven’t had the chance to do anything with him yet and he’s just been chillin on the...

Hello and thank you for reading! I think that my beautiful desert rose bonsaï is suffering from some kind of fungus. A couple of weeks ago, the top leaves started to go completely brown, and I realized that the plant was probably in a setting that was too humid for it... I've pruned the leaves...

I’ve started to notice these black spots, burnt edges, and holes developing in some of my hornbeam leaves. At first I thought it was sunburn but after hearing many people discuss how their hornbeams can tolerate full sun I am starting to think it’s a fungal infection. The tree does seem semi...

I've had this guy for probably a little over a month now. Repotted him as soon as I got him into a 1:1:1 mix of pine bark, akadama, and pumice. He's showing signs of some sort of bacterial or fungal issue I'm guessing. I REALLY hope this isn't bacterial leaf scorch, but from what I've been...

I still haven't found a definitive answer to how to prevent fungus from entering a delicate JM cultivar, like the Deshojo, when root pruning. This is an air layer from South Korea/Japan. I had to do a major cut at the base to have a flatter root plain and this is the result. It pushed growth...

Hi all, I’m a bit new to growing bonsai, started a couple years back. A few weeks ago I noticed a growth on one of my juniper? Should I be alarmed? Not sure whether to cut it or just leave it. Appreciate any help or tips on this. Thank you.

After one year caring for this Chaenomeles in training, and having fought against spider mites during the end of the summer, I am lost to why it is still behaving badly this winter. It bloomed in Autumn. It didn't drop its leaves in the Fall. Leaves are losing their green color, chlorosis like...

Hey Folks, I have a Japanese maple here which was repotted from nursery stock about a month ago. I only made one cut, and that was on the top to shorten the tree. Everything was looking great from the repotting up until this last week. At first, just shortly after repotting I noticed 2 very...
