I deal with cedar apple rust in landscapes almost every day. It's amazing how common it is. People think I must be a genius when I see an infected cedar and go "there's an apple tree nearby" and then we discover their neighbor has one. They don't even realize I'm just a big dummy!
Here in Germany, we have pear and juniper rust. Basically the same idea, just with different hosts.
LEX Laisney, I think there might be salty roads nearby.
@@Yora21 : Might be the same disease. The "cedar" trees native to the US are the Red Cedar, which is _actually a juniper,_ because no "true" cedars are native to the Americas. Add in that apples & pears are fairly close relatives, and it's very possible that the diseases are actually the same one.
@@absalomdraconis I checked. They are Gymnosporangium juniperi-virginianae and Gymnosporangium sabinae. Different species but the same genus.
My cedar gets the creepy galls, but I don't know if any apple trees nearby.
I guess these plants were feeling a little green..
Heh.
Yeah it seemed that they were a bit under the weather...
I’m green dabadee dabada
I’m taking a Disease and Insect class for my landscaping degree, and I’ve already heard about crown gall and cedar Apple rust, so this episode actually functions as a decent study tool for me.
What do you call it when you have to give first-aid to a sick lemon tree? Lemonade.
That was too bad to not be called out on it. Cmon, Therion! You're losing your touch! But you were worth many a good laugh over the last few years, so I can forgive you. For now.
Imagine if a disease mummified your swollen nads. That is how the mummy berry do.
I read this in Ze Frank's voice
@@Tokuijin Me, too.
Syphilis?
I think if you get the mumps as an adult man you have a pretty good chance of that happening... get your boosters lol
Mumps ! Supposed to be very painful.
Michael looks like he finally left the early 2000's fashion timeloop
@@adanactnomew7085 no arguments here and I'm straight. 😘
He should have died half his gottee orange too.
Wearing that twitch shirt too lol
Unfortunately!!!
As long as he doesnt grow a man bun.
Some of those pictures make me highly uncomfortable.
Just imagining that happening to my skin and flesh... Urgh.
I know, that shouldn't happen for a lot of reason but still...
my imagination is not the kind of thing to shut up for logic reasons.
No same I was getting ill just watching
Fun fact: plants get cancer all the time, but it doesn't spread the way it does in animals because of how little plant cells can move, and just turns into mostly harmless knots and similar nodules.
It’s a form of trypophobia, being highly skeeved out by clusters of holes or bumps.
warts are just aninals galls
I never think on thar until i read your comment :(
I gotta say, new videos from SciShow are soooo good at making me happy for a few minutes
This is quite the mood
NullLex00 if only it weren’t so fleeting
Yeah you get to pretend that you're smart with the information you subconsciously thought you understood, but in reality your comprehension was only superficial and will immediately be forgotten.
I had ceder trees all around my house get that apple rust a few years back. It looked so gross
Does the orange pustules permanently disfigure the trees or branches?
kindlin nah, most of the time you can’t even tell anything is wrong with the tree. They only show up after it rains in spring, otherwise they look like tiny shrived walnuts, about the size of a dime.
Him: "The best way to stop this is..."
Me: "Burn it"
You should let Him finish his or her sentence.
I saw one of those crazy gelatinous tentacle balls on one of my cedars and have been been wondering what it was ever since. Thanks Scishow. Lol
4:30 nope nope nope! If I saw that growing on a tree the whole forest is getting burned to the ground.
I will help you. So much NOPE!
Cedar gall’s trypophobia level is over 9,000!
🤣
Hum like certain anime movie call "valley of the wind"?
Looks like a sea urchin
The first time I saw a cedar apple rust gall on cedar, I was confused and in awe as I watched the progression of bright orange jelly tentacles.
As a plant pathology student, this video made me really happy lol, I'm glad you guys are spreading the wonders of plant path
4:30 i saw allot of those when i was growing up and always wondered what they were
I have just one thing to say about that cedar apple rust: *hurrrk*
Always informative, thank you ❤️
Those fruiting apple cedar rust looked like a playdough extruder filled with orange slime! 😜
Surprisingly accurate.
I've wondered how diseases spread in something without a circulatory system. Pretty sure something spread through some kind of flower in my neighborhood and completely wiped them out; it's been more than a year and there hasn't been any new growth in the affected areas.
Fungus can also spread through spores; that's how breads get infected. But that's too ordinary for SciShow.
Mummy Berry: A new flavor of breakfast cereal along with Boo Berry and Franken Berry
There's already a Yummy Mummy cereal.
I like mummy berry better. Lol
@@rainydaylady6596 same tbh
My senior seminar paper was on sexually transmitted diseases in plants. And it was such a weird and cool topic. And when I saw this video, I got super excited!!
I suppose this *should* excite someone.🤷♂️
Anyway, I truly wish you many years of exciting bio-stuff!
The cedar fruiting phase of the cedar-apple rust is the coolest thing you have ever seen.
Post Oak thank you. I thought I was the only one who was like “wait, you want to _stop_ this from happening?”
4:34 100% high octane nightmare fuel
My first job as a teen was a blueberry picker at a small organic farm in Washington state. We always called those shriveled berries "mummy berries" but I had no idea it was actually the technical name for a fungus! I always just thought it was something we made up as kids because they looked like, well, mummies. XD
Oh you meant American blueberries, I always go "What?" when I hear the term blueberry bush, since I always think of bilberry shrubs
This is 1 of your best episodes as its fascinating to learn of such complexity that I havent seen much info on before. Plasmids...wtf?
4:41 'If plants could think' /GrinningFloweyFace
That's a wonderful idea!
You know what plant is always sick? Coffee
Alexander Vlk, you’re fired. Leave now.
I don't even get the joke i just regurgigate others. You're fired but the coffee is great.
The coughy plant is ill, not sick.
Soo precise n clear to understand. 👍🏽👍🏽👍🏽
Great vid! Just one thing since it is fresh. where you talk about the tree grafting you show a picture of a grafted tree. The catpion says mango tree but its actually an olive tree. Keep it yp!
I was expecting Broomrape to be on here. Oh well, guess I’ll go watch Sam O Nella
There is a orange rust fungus that attacks pine trees but it requires certain oak trees to complete the life cycle. In counties and areas that have vast pine tree plantations oak trees have been banned, cut down to break the life cycle of the rust which causes serious financial damage to the biggest employers and landowners in the area.
Mummy Berry DID make a really good cereal, though.
This whole time I thought some types of cedars just had weird flowers. They were odd to step on when wet, and gave off mad oceanic vibes.
It should be noted that the tree known in northern parts or North America as a "cedar" isn't really a cedar at all (it is a thuja) and likely doesn't participate in that last disease's cycle.
Thanks for this video! I've seen a lot of these things in my life and never had a clue what they were.
Brilliant channel!
3:03 hold up, how do you know what "alien-like" is? SciShow, what are you hiding from us?!
Took a long walk yesterday and spotted a lovely pioneering, juniper couple growing in a field, it was sad to see they were both infected by Ceder-Apple Rust and that their kids had died....
Cutting down a bunch of cedar near my house this year for this reason.
@Megan McCarthy King why is he a loser? Lol

Mr. Perrin, Taylor (Tiny), Cherie, Charles, Shawn, Rayden, Kurtlin, and Brent!
It's always super awesome when you guys put out botanical content 😄 Great research, guys.
Huh. We had crab apple trees, neighbor had juniper trees. They got sickly looking and we cut them down within a few weeks of each other.
Awesome information! Well researched and presented. Thank you!
thank you patrons
Ahh... yes. I, too, burst outwards with slimy orange tentacles when I feel I'll.
1:07 that mango tree looks a lot like an olive tree! Thank you for the videos!
I have apple trees. I have cedar trees. The mystery is solved now.
Shouldn't there be a pen in there somewhere?🙃
sounds like it should be easiest to cull in the "cedar"(really a type of juniper) as it lasts longer/grows slower
@@Dragrath1 You can also offer some protection against rust for the apples if you bag the blossom clusters at the start of petal fall, and only remove the bags when you thin the clusters, then replace the bags till harvest. This also helps to control insects, though it can be a bit labor intensive if your apple trees are large.
This... actually was useful to me instead of just interesting this time. I have both cedar trees and wild blueberry bushes in my yard, and I've noticed both of the weird things happening to them, the galls and the shriveled berries.
The cedar tree in my front yard had the orange slimy things on it last year and I thought it was some weird kind of squirrel poop. The more you know!🌈 😃
Oh my god, so *that's* what those weird things were sticking out of the bottom of leaves I found while I was responsible for mowing the lawn at my parents'. I was afraid to touch them bc I thought it was some sort of insect egg thing. I think? I'm glad to know it was cedar apple rust. Must've been cedar trees in the woods behind our house.
I'm not a rocket scientist but that "Grafted Mango tree " looks an awful lot like a grafted olive tree
More and more stuff I did not know! Thank you, folks!
That twitch shirt was the last thing I expected to see lol
I like your shirt man.
I discovered a mushroom growing on a marshmallow in between two graham crackers.
It turned out to be a fungal s'more.
He's back 🥰 and like fine wine, only ripens over time 😍
Well, read a book on that, and apparently, plants can definitely think! It helps them calculate if growing more to the right where there is more sunlight is worth the expensive cost in resources, or to see if they want to do deals with other plants in the neighborhood, or fungus or bacteria...
This made me itchy...so...thanks for THAT!
Are you a plant?
I have cedar apple rust in my backyard, I have an apple tree and cedar trees. I saw the orange goo last year on one of the cedar trees.
great video
Yesss!!! More plant videos pls!!!
I pick blueberries in a natural swamp/bog, and after I'm done I clean the bounty outside my front door, I remove leaves and hardened berries and spiders and bugs. I sweep them into the flowerbed 3 feet in front of me, and I have been wondering what those circular fungus things were. I thought they were from the mulch. Wow. But I discarded zero flowers. How did they get there? At 3:02
Edited: inserted time reference
That first one is making bananas going extinct. We lost one type of banana already.
Gros Michel isn't completely gone, but it's literally out of business...
@@edi9892 judging by the artificial banana flavors based on it, I don't lament its passing tbh.
I'd like to keep eating the current banana's though.
@@edi9892 um sure about that. We switched to different banana. because of the first bug and people carrying it on the bottom of boots.
If the Cavendish gets replaced by the smaller Hawaiian apple banana, I’ll be thrilled! Cavendish is starchy, then ripe for less than a day, then oily and mushy. The apple bananas last several days in the ripe stage. They kind of ruined Cavendish for me. Unfortunately, you can’t get Hawaiian bananas in the continental US unless they’ve been irradiated because Hawaii has so many native fruit flies that they don’t want coming here.
@@evilsharkey8954 could happen. We switched to that current because they said the disease wouldn't affect them. But it did, hopefully we can just stop the disease.
How about a video on plants immune system !
Too cool!
Think about how weird plant diseases are. Now think about how more bonkers aliens would be.
Nature can be so diabolical !
Fyi 1:05 is a grafted olive tree, not a mango
"These diseases don't kill their hosts, just inconveniences them."
Why did this remind me of the Hellsing manga/anime? [Specifically the crazy young vamp couple] I get the logic, but still.
They really should burn the mummy berries. Didn't they ever play D&D?
Fascinating!! 👍🏻😃
Fascinating!
Yay!!, love you SciShow
Wow I have a degree in plant pathology and have never heard of the latter two diseases. Guess we don't get these fungi in tropical areas!
Always super informative in an accessable way. Bravo!
Also, where is that awesome fadey purple shirt from? I know someone who would love one.
His shirt though. I'm dying
Fun fact:
Bananas contain a neutral chemical which can make people feel happy. 🍌
Is it sugar?
Crown gall creeps me out. It seems more like an SCP than a normal disease.
Edit - 4:29. Nevermind.
Michael 😍😍😍
I have a doubt.
What is the weird knot-like nodules seen in the tree Millettia pinnata.
Scishow pls answer this question since I have this doubt since a long time.
I know we ask for visual aides in a lot of the videos, but
That last one, I think I could have gone without
Currently watching this at work while I'm highly positive I have the flu 🙃
Someone tell me why plant diseases freak me out so much more than human diseases
Fascinating how often times you can't simply tell what the real reproductive unit is in evolution
The Cedar Gulls are absolutely disgusting I’d immediately go to the hospital if one touched me
This just popped up on my RUclips algorithm. Little did Micheal know back in February that his hair is about to get w a y longer...
Hello everybody
This sht so good to me. Thank yall
It's great to know that plant diseases are much more freaky than most diseases us humans get...
I was wondering why I saw tentacles on my neighbor's tree. Now I know why, but I really wish I didn't
Nice shirt buddy. :)
every time you smell a flower, you're burying your nose in plant genitals.
Do plant's have a type of immune system? or any way to combat infections?
All the trees around my house grow the cedar rust and it always is freaky.
Can you get siuck from the fungus or fungus consumtion? Cedamaria
A Horticulture video! Yay!!!
I've seen cedar rust before I think not sure though
When the plant puts out new stems, and leaves... where does it go?
We have both Mummy Berry and Cedar-Apple Gaul here.
