This reminds me of when I went to visit some of my wifes relatives in northern California in 1974. While I was walking around the property I found a large number of those mushrooms under a very big maple tree and mentioned to them that it was a bad sign for the tree ! The tree looked fine at the time so they dismissed my warning, one week after we left the tree come down and caused almost thirty thousand dollars in damage ! Almost every root of it was rotten ! They went through a lot of trouble but finally got the insurance to pay for it ! I don't see any mushrooms where I live but when I travel I still catch myself looking even now many years later ! Thanks for sharing and take care. 👍
We have quite a number of silver maples in my area. It's good that you talk about them more than just a time or two. In all cases I think we benefit when you "repeat yourself".
Many people when buying a house will engage a building inspector to assess the house for problems , I think more people should get a qualified arborist to assess large trees that present a possible current or future hazard or large expense before they sign the purchase contract .
Hello Blair Glenn, this red fungus at 1:42 is called Fliegenpilz and quite common here in Germany. I guess it likes the moister climate here more than the Californian one. Don't know if I've seen the Armillaria mellea before, but will be aware in the future. Stay safe !
They're fairly common on the coast north of San Francisco (where I"m at). But I'm surprised Blair doesn't see them very often, the Santa Cruz mountains are very similar to where I live.
arboristBlairGlenn One day I’ll be on your level. You seem to run a tight ship and you have a passion for what you do. I can dig it man. I watch a lot of other climbers/fallers who own businesses as well as CZcams channels but you’re on the next level type. Hopefully I’m not too busted up to still be at it in 20 years. I know my climbing days are coming to an end soon I’m sure. Going to have to step it up here soon.
Mike Frizzell I’m 65 and still climb. Not as fit for sure but a lot smarter in how I work. Go easy on the body and it will last. Break it, and you will pay for it later.
arboristBlairGlenn I’m going as easy as I can these days but I was wounded in Iraq back In 09 and am feeling it a little bit but we drive on ya know. You’re a savage sir. I know a few fellas around my town that still climb that are getting up there in age. We’ll see though. Stay safe sir.
Fungus deliquesces. In effect, it means '[decays into] to liquid'. Most wood contains fungal spores and filaments throughout the whole plant. The fungus takes over when the tree is compromised in some way, and the 'fruiting bodies' (what we call toadstools, mushrooms, puffballs, Jew's ear, chicken of the forest, etc.) generally appear when the wood has decayed (become sufficiently digested), thus providing enough nutrients for the fungus to fruit and spore. Even only one root fungus toadstool is therefore an indication that the tree is dying. Thanks Blair.
Rebecca S. The mushrooms develop from the fungus that is in the wood and roots. Once it is showing, then that means the tree is pretty far gone. Even if the foliage looks ok, with rotting roots, whole tree failure is the concern.
I've eaten the honey mushroom. You're very correct about that root decay. I have some growing in an oak grove that was damaged and dying in the last few years. Those taste best when they're young and button looking. Definitely something to watch out for!
I haven't witnessed this problem here. You recently mentioned the area you work trees in has many "rules." I wonder if these rules are keeping trees around long enough for mother nature to take its course. Hopefully this homeowner's home insurance company isn't watching YT. Glad no one dies from a falling house crushing tree you told them to cut.
@@arboristBlairGlenn True you didn't expose the common knowledge of location. Glad we see eye to eye on some rules can be bad. Maybe they were made up mostly by non-tree people? You're welcome ... comments be them good, bad, positive or negative help if people can simply open up to the opinions of others.
By far the deodar ceder tree's are my favorite. Im a fairly young man, but when i get my own property it will be the tree i plant. I love the way it looks and shades. and i think its perfect for my location (Southern California). What should one lookout for when planting such a big tree? plenty of open space and nothing below the root system any other major tips? also i see alot of the deodars tops being cut off in my area, is there a reason why? i want to make sure im planting the right tree. but man i love the way deodars look.
Deodar and Blue Atlas cedars are beautiful trees that I admire greatly but I feel that they should only be planted in large landscapes, parks, big estates and the like. They are structurally and aesthetically so dominant that the rest of the plantings and sometimes even whole houses seem to cower beneath mature specimens. ~ California should be educating home owners to be on the lookout for oak root fungus mushrooms every winter, what their presence means for the trees and what action needs to be taken. ~ That was a beautiful amanita 🍄. Unusual to see one outside of a forest setting. Maybe it came in on some soil amendments when the property was re-landscaped.
arboristBlairGlenn - Typically bags of compost, etc., list ‘forest products ‘ as one of their ingredients. This usually means the leftover ‘waste’ products of the lumber industry.
To clarify, the fungus grows in the roots of a failing tree that is weaken with age or human error? Or is it that the fungus attacks thus killing the tree? btw as a lawn mower guy, these make such a mess. And I would be spreading it on my mowers right??
I've seen a few of those Amanita mushrooms in the Indian Heaven Wilderness and other areas in the Cascades, in the greener high elevation areas of Oregon and Washington.
This video is great at pointing out what to look for but doesn't tell how to treat it. If you start seeing this do you immediately just cut the tree down?
Amanita muscaria - intresting, in Europe (Czech Republic) there are lots of them. Beautiful, but nothing special. On the other hand - I have probably never seen Cedrus deodara. There are also plenty of Amanita rubescens here - very tasty when prepared as a schnitzel.
Hi so i noticed the honey mushrooms at the base of two of my trees. I removed about 6-12 inches of soil around the root collar of these trees earlier in the spring. There is minor amount of wood rot around the tree. 1/2 into the bark in some places. We did a bunch of pruning as well. Im having our arborist come back to take a look. Is fact that the root flare is now not burried it can dry out and heal ? or is death inevitable at this point since its infected . There also tiny mushrooms growing on the tree bark. Thank you
This fungus grows on the wood and roots and resolving the issue is not at all easy. Can’t get the fungus out of the system of the tree. You can slow it down but that’s about it.
Could a person plant another tree in that area or would you have to wait until the fungus runs out of food? Just wondering about that and what kind of issues it would cause for future plantings. Great video.
Thank you for this video - pretty certain my huge Peruvian Pepper tree is afflicted. I'm worried about the tree trimmers I will have to hire. If it's this dangerous - how can it be safe for them to get up in it?
That's sad about that madrone tree. I think they're beautiful. And the tree in the customer's yard, I'm surprised the rest of it didn't fall over. That could have been worse than it was. Well at least the damage was minimal
Armillaria m. is a tree killer, and is not effectively treatable. It affects a vast number of woody trees and shrubs. It tends to affect plants under stress. I have it on part of my lotin Houston. The fruiting mushrooms are most evident in the fall in wet conditions and looks like a disgusting black slimy mess when they decay, as you say. It is supposed to be one of the best, sweetest edible mushrooms, -hence the name. Is this right? I've never tried to eat it even though I know it's there every fall. Have you ever tried it? It's called the honey mushroom. .
stevieph100 yes, I have eaten it many times. Best when small buttons. However, (and this is big), some people have a bad allergy to this fungus and will get very sick. So, be warned.
Paul Morissette no, the mushroom are just the fruiting body of the problem. The roots of the tree harbor the fungus that you only see when the mushrooms erupt in the first rains.
Brooke S the mushrooms are just the fruiting body of the fungus that is growing through the roots. Not something you can “cure”. You can choose plants that are resistant to Armillaria.
Sean Tomei lets start by understanding this fungus. You only see the fruiting bodies when the roots are so full of the fungus that they erupt. The problem has no cure
I know in that area y'all have a climate that you can grow more varieties of trees than any one else. With that said i have to ask why in the hell would someone in that area plant such an ugly tree with such weak wood like a silver maple? Outta all the trees you have to chose from and you chose a silver maple lol!
Matt Lloyd most people don’t know what to expect. Actually a big healthy Silver Maple is an amazing shade tree. Most, however, are full of pruning wounds that lead to decay.
@@arboristBlairGlenn sorry blair just like bradford pears I'm a bit prejudice towards the silver maple not a fan. I can say I'd love to have deodar cedars i can grow Karl Fuchs Cedrus Deodara but its not a California xmas tree in stature. But back on track lol outta ALL the exotic trees someone gets a silver maple lol I'm such a tree snob i just don't get it living in an all you can plant tree buffet! Living in 4 seasons country i have to say its amazing what y'all can grow but at a cost yall gotta have irrigation if I'm correct?
Matt Lloyd irrigation is needed but now that water costs have become so high, many people are turning off the water and asking me why the trees are dying???

Wow really nice to know, thank you for sharing it.
Agnos Jr. now keep your eye out for this
@@arboristBlairGlenn for sure but I think that when we see the mushroom that root will already be all taken by the fungus right?
Did you say it was oak root fungus on a maple tree? How to you get rid of it and can you make the tree healthy again?

Thank you, super Video!
The word for mushroom 'decay' is deliquesce. That is to say the decay of the fungal body itself not of the host material
.
John Ivkovich Thanks John, I’m afraid if I had used that in a sentence, my audience would decay.
@@arboristBlairGlenn You made my day!
To clarify, the fungus grows in the roots of a failing tree that is weaken with age or human error? Or is it that the fungus attacks thus killing the tree? btw as a lawn mower guy, these make such a mess. And I would be spreading it on my mowers right??
Trooperandcooper Ale the spores spread when the fruiting bodies (mushrooms) bloom. This fungus attacks healthy tissue.
These should count for ISA credits!
Jacob's Ladder Tree Tech I think so too

Good question. No simple answer. Every tree reacts differently. No cure.

Each climber needs to assess the tree prior to ascending.
In your estimation was over irrigation and root damage a possible cause for the spread of Armillaria Mellea in the landscapes you showed us?
Erlend Greulich Frontier Big Wood Climber too much added irrigation to damaged roots is a factor here.
That's sad about that madrone tree. I think they're beautiful. And the tree in the customer's yard, I'm surprised the rest of it didn't fall over. That could have been worse than it was. Well at least the damage was minimal

Big silver maple I'm just wondering how much it cost to remove a tree of that size in California
Gregg KUZILA the removal was not that big. Had it done in an hour. Part of a bigger job. Based on 85. Per man per hour
Its mushroom season! I like to eat black trumpet mushrooms occasionally, and a channtrell or two.
Home Land Freedom no black trumpets yet
Blair, You know your mushrooms 👍
we have loads of those mushrooms ( red/white..) it lifes in symbiosum whit beachtrees it does no harm
Martin Spijker you are referring to the Aminita?
Maybe ground fires to keep the mushrooms in balance?
Paul Morissette no, the mushroom are just the fruiting body of the problem. The roots of the tree harbor the fungus that you only see when the mushrooms erupt in the first rains.
How do you stop that rott
Change out the soil, sterilize, plant resistant
BLAIR DO YOU EVER ASK TREES TO COUGH ? THANKS FOR MAKING THESE PHYSICAL EXAM VIDS..FOR THOSE OF US STUDYING ARBORICULTURE THEY ARE HELPFUL.
Matthew Polo I do draw the line at talking to trees.
Help! is there any way to cure this fungus with peroxide or fungicide if caught early enough? Its taken over almost every tree on my property.
