fungus

Hi all! Looking for help to identify these bugs that appeared on my Vietnamese Bluebell over the weekend. I have my bluebell indoor just for the winter as I live in NY. I treated the plant right away by removing what I could and spraying a mixture of dish soap and water. Want help to identify...

Hi all. Back in April, I bought a Nagasaki Crabapple from someone from my local club. It was very healthy then, with flowers just finishing up. However, in early-mid June, I noticed that the leaves were browning and curling up. I was quite confused as I'd never encountered this before, but then...

I have this Pomegranate hardwood cutting that has been in a black bag for almost 2 months now. The tree is producing a lot of shoots, however most of them are turning their tips black after they start to elongate. At first I thought that it was because they were getting burned after having...

I received these from Evergreen Garden works, the first, smaller one in late July, the second larger one in late August. Both trees looked very happy and healthy upon arrival, but after getting the first one, within a week I saw the first signs of these dead leaf spots. A month later I got the...

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?

?Hino Crimson? azalea with wavy leaves, thinking the fungus visible on the trunk is causing general sickness ID of the culprit? Other azaleas are fine

I’ve never seen bird poop damage a leaf (I’m 95% sure this is bird poop). So either this one was one helluva shot and hit this existing dead spot, or the bird poop damaged the leaf. Is the damage from a pathogen or possibly fertilizer burn from the poop (which I’ve never seen before)? The mold...

I’m still struggling to figure out what’s wrong with my American Hornbeam. A ton of leaves have these black spots showing up on them. I suspected fungus so I removed all the leaves with spots and sprayed with fungicide some weeks ago, but that didn’t seem to have any effect on the tree. Overall...

I found maybe a handful of leaves with these bumps on them, pictured below is one of these leaves, front and back. I only see this on a handful of the leaves,however, all of the leaves have brown tips. I see the tips on new growth browning as well, although it seems to be less severe than the...

Hi all, new here. I got my first bonsai. It was stored in an outdoor greenhouse but is an indoor plant. I took it home, put it in place (window with natural light) but the following day i noticed this on the soil. Is this an issue for the plant? Or just symbiotic with the soil and tree?

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...

Hi everyone, i own a fee green island ficus and never noticed these light grey dimples in the leaves before, they're on a new GI ficus i just purchased and I'm concerned whatever it is may spread so I've segregated the new plant. Anyone have any idea what this is? A fungus maybe? I've checked...

Hi everyone! Technically my first post but long time lurker. My largest willow cutting that I got on a lark appears to have gotten a potential fungal infection from our latest downpour (or I assume that’s what the orange dots are). I know that the top evidently has dieback and I need to chop...

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...

I'm interested in your experience with cultivars of everything commonly described as a Japanese maple, regarding their disease resistence. I could not find anything on this topic beyond throwaway comments Especially curious what people say who had multiple cultivars, over several years, and...

I bought this texas scarlet chaenomeles japonica at a big box store last month, since it looked healthy, large, and relatively low priced. It was only after I took it home and started chopping away all the twiggy growth that I noticed my intended trunk has some reverse taper in spots. If it just...

Hey guys! Do you know what are this brown things on the soil of my bonsai? Are those small mushrooms? Or what? Most important....good or bad? Shall I remove or leave them? Thanks in advance Regards

Hi there I haven't posted in a while but I just recently purchased this older Japanese red pine. Compact Tanyosho ( Pinus Densiflora Umbraculifera- Compacta) I traveled to Chester CA and found this. Originally priced at 99 but I pointed out the ailment and the nursery owner accepted $50. She...

I recently got a bonsai tree for christmas- I have no idea about the nursery conditions etc because it was a gift. I belive the tree is a chinese privet- it is my first ever tree Arount the start of the tree trunk it looks as if it's decaying and it has white marks around it with orangeish...

Hi All, I recently noticed what looks like a red scale on my Chinese Elms. Here are some pictures from the largest Elm which appears to be the most affected. It runs off quite easily and is powdery, but there is a lot of it on the trunk and primary branches. This particular tree gets 4+ hours...

Hello all, Let’s play name the fungus, if you will please? I swear I’ve seen this in pictures on the internet before but it’s no tar spot or common black spot, it looks.... worse. It’s a Maple, Beni chidori. It appeared on random leaves, not localised or on new or old leaves. Tree is otherwise...

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!!

Hello all, I am having a slight issue with my juniper that I was hoping you kind people could help me get to the bottom of. The tree overall looks pretty healthy, nice color, new shoots, all good there. My problem is with the tips of some shoots and even some old growth. I'm aware of the...

Hi fellows. One of my quinces is losing its leaves, they get yellow with brown spots from night to day. As the others are ok and humidity is low overall, I guess it is a fungal issue. Should I try Daconil? Neem oil?

Hello! I live in Buenos Aires, Argentina. South hemi. I have a chinese elm I have air layered from a bigger tree 3 years ago, it was always going very well... but this summer it got a fungal issue, i threated it with Folicur once a week for 4 weeks, like I usually do with other decidous trees...
