fungal

I noticed my azalea recently has what appears to be blotchy brown spots that I suspect may be caused from slight sunburn or a fungal issue. I’m leaning towards sunburn though and just want some second opinions. Planted in 100% kanuma. I’ve been watering about every 2-3 days depending on needs.

I am posting a new thread for this just to have more people take a look and provide input. I am thinking I may be dealing with a possible fungal infection of this field grown trident maple that I repotted last Thursday. What do you all think? Most of the leafed out growth has blackened tips...

My oriental sweetgum recently started browning, but to me it looks more abnormal than your typical sunburn. I try and keep it well watered, with current temps in the 100s, it’s getting watered about 2-3 times a day. Part of me is worried it might be a bacterial leaf spot, or something like...

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...

Posted a few weeks ago and since then my juniper has declined even more. Any ideas on what I could be dealing with? Do I need to cut everything off except for the one tiny healthy branch? Little black spots everywhere. You can kind of see them in the pictures but the main concern is all the tips!

I went on vacation for a month and had my brother watching this little guy. Came back and it’s not looking good. Started treating with been oil a week ago showing no improvement. Anyone know what this is? Fungus? Blight? Insect? It’s all the little black dots everywhere. And some of the tips...

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...

Started noticing some browning on my cedar elm. Not sure if it’s fungal or pest related. It’s still been fairly warm here and feels a little early for color change. Highs in the mid 80s, lows in mid 50s. I treated it with Bayer Rose and Flower 3 in 1 about a week ago. I’m wondering if that only...

I’m so ready to give up on junipers. The few I’ve had just have had constant issues. This one has been a struggle since it first arrived. You can look back here at the history of this tree: https://www.bonsainut.com/threads/struggling-junipers.49569/page-3#post-946547 I think now I’m having an...

I'm thinking this is either fungal or light related. I have a Kentaro san JM which the newer leaves have tighter ridges, more defined lobes, some deformed and only having 3 points. I've treated earlier in the year with Bonide granular fungicide and insecticide. I'm guessing it's about time I...

I just wanted to make sure this wasn't a fungal or pest problem and just sap. I'm still fairly new to pines so wanna be sure.

Hadn't noticed this before, but it's only on one ficus. One of those hardware store ginseng ficus graft trees that I got when I was first starting the hobby. Anyway, the other day I noticed these white uniform dots all along the leaves. Any idea what this might be?

Hello all, I have a trident maple thats very dear to me that is sick and i cant solve it. I've tried a few things that have been sugested to me - I treated it with a spray for fungus as instructed on its lable and added a fortifying mixture that is sold here in Portugal. The tree has been in...

I’m wondering if anyone has the answer to this. I’ve noticed some new growth on my Hornbeam has started to develop this brown edges to them. The edges while brown, are not crispy or dry when they first develop. My tree is kept in the shade for as long as possible throughout the day, but gets...

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 bought a juniper yesterday and found a couple lumps at the trunk. Are these galls or just callouses or something entirely different? Thanks in advance

Hello! I'm adding pictures of one of my affected trees - I don't know what they have - In this case is an ilex serrata. We are in fall here, soil was very compact so I repotted without touching roots into a bigger pot and new lava rock. What do you think? Thanks!!

Hi everyone, I would like to ask you all for advice on how to save my bonsai tree. I have this tree for the past three years and I believe that this is a privet bonsai tree that is approximately 13 years old. As this was my first bonsai tree, initially I did not know how to take care of it...

My satsuki azalea is killing branches.. this has been happing for about 3 months.. I thought it was because one day if was not watered, but now, branches that were well 1 month ago are dying now, I already lost 3 branches.. what do you think is happening?

My itoigawa juniper is suffering, dying - probably already dead - but I have to try. Do you know what could be happening with it? and what do you recommend to do? I think is an intoxication by excess of Phyton-27. 2 months ago: Now:

Hello! i'm having problems with a Chojubai i brought from Barcelona 3 weeks ago. I'm in Buenos Aires (Southern hemisphere), I tried to simulate a spring here because it is getting cold. April 11 (barcelona): April 19 (barcelona): May 1 (barcelona): May 9 (barcelona): May 13 (barcelona)...

I thought that with the end of the spring monsoon, my fungal issues may be lessening. Its been hot and sunny here in middle Tennessee, but still humid. However, I am seeing something come up on multiple leaves on multiple trees and I was hoping someone in the community could help me identify...
