Tree Cavities

5/10/97-Host Brenda Sanders is joined by Oklahoma Department of Agriculture Urban Forestry Coordinator Mark Bays to discuss proper care of tree cavities.

[@arboristBlairGlenn]

Need to study Shigo’s experiments on the pros and cons. Foam does not help. I have seen filling the cavities to help prevent mosquito breeding water pockets. Filling only hides the problem and prevents future inspection.

[@akashkedia4618]

Thanks a lot for making this video.

[@GrimmGhost]

I've spray-foam filled the hollows in trees then used Spectracide Pruning Seal (an aerosol spray, black in color) to coat over the foam. I've also sprayed a coat of "Leak Stopper Rubber Flexx" (white in color) over the foam and freshly cut branches. Works great.

[@mrawesome2742]

GrimmGhost What kind of spray foam did you use to fill the hole?

[@GrimmGhost]

@@mrawesome2742 Recently I've used: GREAT STUFF - Insulating Foam Sealant - Gaps & Cracks. 16 oz. with the Quick Stop Straw.

[@paulhunter9613]

@mr awesome He said to use a urethane foam then seal with body filler

[@Flashblade]

You don't need to do that and shouldn't do that.

[@thomasholmes7070]

Very helpful. Thanks

[@DAS-Videos]

I think he made that all up. Body putty?

[@matekilim7897]

Calcium carbonate or dolomite works amazing I put some to rotten hollow and black.thing start growing oit aftetfew days I removed it and patmore and now is leaking out but it have lime all around to sanitise it Bless and good luck with God's work

[@michaelpcooksey5096]

So if trim off a 5" limb whatever happened to spraying the exposed wood cut with a pitch bandage?

[@michaelpcooksey5096]

or orange oil and beeswax. See kzbin.info/www/bejne/q5PEnXtniK97hs0

[@frankphoto2]

Difficult to find urethane foam filler. Seams polyurethane is what's readily available. Even stuff labeled for tree repair is poly. ? Is it ok to use poly ?

[@Tryinglittleleg]

Same thing dont fill your tree holes

[@mightyconker3903]

Just don't do it.

[@DAS-Videos]

I filled a hole in my apple tree with foam decades ago, my own idea, and the sun broke it down and it did nothing. I think filling it with cement would be better. Can mold cement to a shape to repel rain and maybe easier for the tree to grow over it.

[@joshuamahaffey7163]

He said cover it with autobody filler because it breaks down..

[@matekilim7897]

Calcium carbonate work fine fo repairing cavities in trees. just mix it with water 1/5 ratio more less and wash off around wounds and inside cavities. If you paid tree with natural clean calcium any will benefit from it moss start grow on place off rotening roots and fill up hollows. Dint need to fill it up just pain around nd tree start sealing wounds really nice. If you do that after prooming with wound, you make seal, and tree won't suffer from anything growing in.

[@spankymagee]

I used a torch and burned the decayed wood. Like cauterizing it was my idea and because bugs don't like smoke and burnt wood.

[@wilmalloyd]

Thought foaming into a tree has the same problems like cement...The water still seeps in?

[@readysetsleep]

The foam actually holds water and causes it to hold moisture and eventually speed up the rot.

[@Koraxus]

what about mud or clay? what is a good solution?

[@RemedialHappyMan]

he said they filled that a year ago, and if you look at the foam (that expands to fill the cavity entirely), you'll see how much has deteriorated and decayed outside the foam.

[@rhmayer1]

Most arborists today prefer not using foam or anything to fill a cavity. Once filled you then never know the extent of the problem. Better to be able to inspect the extent of the damage. Plus the foam doesn't really seal along the cavity, since there is a dirt layer even if blown out. So water can seep in around the foam, along with insects and pathogens.

[@rhmayer1]

@@readysetsleep Not really. The foam they use is closed-cell foam - same as what is used in roof repairs and sealing roof penetrations for solar system mounts. That said, you're right about foams potential for speeding up the rot. Most arborists today prefer not using foam or anything to fill cavities. Once filled you have no way of knowing the extent of the internal damage. Better to be able to inspect. And the foam doesn't seal to the wood that well anyway due to dirt between the wood and the foam. So water gets in around the foam, as does insects and pathogens over time and so, as you said, the foam could actually hold the moisture in and prevent evaporation when the warm/dry weather comes.

[@cathyherring6424]

Thank you that was really good I was about to fill my Apple tree with concrete but I will use foam now that I’ve seen this 😇😇😇

[@matekilim7897]

For Apple trees every year white wash with calcium solutiin is like critical is good for all trees specially ones that are damaged. They just. Grow faster nd regenerate thanks to calcium nd carbon they can ged rid of toxins from pollution.

[@arunbhoomkar8700]

I love cavities in my trees . I deliberately create rot holes .. lots of birds bats and squirrels live in them .... got a fantastic hollow tree which is a protected bat roost

[@Gbos551]

I just watched two videos with an abortionist who spoke of cavities being filled with ether concrete or foam and he didn't like ether one. He didn't say what to fill the cavity with but he spoke against filling the cavity.

[@randomhouse2200]

An abortionist? Seems like someone who does abortions wouldn't be the best person to ask about filling trees.

[@mightyconker3903]

Filling cavities doesn't work

[@slpip4365]

Should use an insulation foam sprayer to fill up the hole.

[@denisecody3639]

doesn't the foam hold water????

[@rhmayer1]

No, it's closed-cell foam. But this video is dated. I believe most arborists avoid filling cavities. Once filled you can never inspect to see if the internal damage has gotten worse. They seem to hold the ability to inspect and then better determine the extent of damage than to cover it up. The foam doesn't seal well anyway since there is a dirt layer when the foam is applied. So moisture still accesses the cavity, as well as insects and pathogens. If you're really worried about getting water inside then maybe you can glue some kind of flap over it, glued along the top and upper sides?

[@mightyconker3903]

Yes it breaks down and becomes wet when submerged

[@michaeldougfir9807]

I have shared Mark's videos for years.

[@Noblecheesehead]

Thank you for the great information!

[@tjshively01]

Other arborist say NEVER foam a tree. So what is the TRUTH

[@Tryinglittleleg]

NEVER foam a tree. The foam traps moisture and speeds up decay.

[@mightyconker3903]

Don't do it. This is a dated practice that we know not to do know thanks to the research of Alex shigo and many others

[@guidedbygreen1480]

Don't fill your trees wit anything, this old thinking, no longer arborist industry standard.

[@FreeAmerican]

Most Arborists: Don't foam trees Me: Then what do you do?

[@mightyconker3903]

You leave the cavity. If it looks like it has bacterial infection you can use lime on it to reduce the pH.

[@arunbhoomkar8700]

Thankfully I am NOT an American 🇮🇳❤🏴󠁧󠁢󠁥󠁮󠁧󠁿 ...I loved the life an times of drizzly Adam's Thom Pace ........ BUT I love cavities in my trees & deliberately create rot holes .. they are homes for bats birds & squirrels .. my hollow oak is a protected bat roost so have no mosquito problem .... have a dead standing tree snag in which woody woodpecker hollowed out a nest ...........God bless America even though I am not one...

[@nathanreed3857]

The tree is not supposed to be rotting on the inside. Our towers have much impact on the elevation of the clouds, inadvertently forcing water up and drownding the WORLDS trees. Towers also stop natural evaporation process and block our aether field which is the wave we all ride on.

[@wilmalloyd]

what?

[@hemicharged70]

Debs Lloyd i thought it was just me😂😂😂😂

[@BigDaddyThrock]

Nathan Reed take off the tinfoil hat and step away from the redwoods

[@mightyconker3903]

Towers do affect hydrology. Don't be obtuse

[@nathanreed3857]

Hahaha if you only new,,, watch any of my other videos 📹 🤣

[@FirstPlace97]

1 month to the day of my birth lel

[@arunbhoomkar8700]

Thankfully I am NOT american

[@creedjo4018]

Very interesting

[@earlrussell1026]

You must love Jehovah your God with all your heart and with all your soul and with all your mind and with all your strength. You must love your neighbor as yourself. Jesus the anointed is Lord! Repent and be baptized and believe the Gospel.

[@jlnbroadcast]

Amen.

[@adamgeorge37]

wow this is so outdated and incorrect.
