WHY YOU DON’T TOP TREES (explained)

[@evanoldhoff4904]

A quick tip that may save a life. If you noticed how when he was dropping the stem, they stacked all those logs to use as a crash pad, to stop any damage underneath. I’ve used the technique for years. One day we went to apply this technique, we didn’t make the crash pad long enough, when the tree fell over on top of it, it spat one of the logs out like a cannon, directly at myself ( I was pulling the rope to assist the fall ) it smashed both my shins, no bone breakages. But I could barely walk for a month. So many years of using this technique. I’ll never use it again, because of this one instance

[@cousineddie3302]

Crash pads are fine but you must do your do diligence

[@13r4nd0]

@Cousin Eddie Agreed because laying them out just right is important. I have seen the worst side of the trick a few times, thankfully not by me but some I worked with. Still, I wouldn't deter from using that technique if in a time pinch. As long as you take your time at the right time. IBEW-

I've never seen such a setup before. Loppers here in Auss just cut the tree into manageable parts not large enough to cause damage in the first place. Didn't think anyone would be stupid enough to do it any other way.

@@arboristBlairGlenn the other tree guys around me are the most substantial threat to the trees around here. even worse than the emerald ash borer. you look around town and almost all the old maples are topped already. most are severely dangerous now and everyone is starting to hate having trees because they loose big limbs every time the wind blows. we just had a few huge maples fall through some buildings and everyone thinks its from the abnormally high winds. forgetting to realize that its really cause someone destroyed the tree years ago and the roots finally turned to mush. or like mine the gas company cut apart the roots on 3 sides of the tree to run a line to the house.

One thing that you did not mention in your video that I think is important that when trees are topped or even cut back very hard the sprouts that originate from those cuts are not attached to the center of the trunk as are original branches making them very weak and more prone to snap off.

I have 4 and a 1/2 acres of trees that I've grown from seed or very small seedlings over the last 47 years. It is interesting and educational to watch how the trees have responded to my pruning over this time period. Sometimes things that you thought were the best choices turn out not to be so 20 or 30 years down the road. All we can do is learn from our mistakes and try and do a better job as time goes forward. Some of these trees are now 60 to 70' tall, which is a big tree for the arid West where I live. They require constant irrigation. If you ever make a trip out to the West you would be welcome to stop by and see what I have done. Many trees that started out doing well after 20 or 30 years prove not to be good choices for this climate and soil. Many turn out to be better choices than I thought as time goes on ,such as some of the pines. Thank you for your work and your response to my replies.

[@electronicfreak1111]

In Australia a lot of our trees are a lot more resistant to this but one that isn't too resistant is paper bark but the plus side to paper bark is and they can be hollowed out completely and just sort of live mostly fine because when they fall it's from the roots being damaged usually because of wet soil which is where they grow

[@CATASTEROID934]

The innate weakness of the types of hollow trees that the South Island Short-tailed bat chooses as roosts has likely served to shape the unique Short-tailed Bat Batflies that are associated with their roosts- most Batflies are blood-feeding parasites but those associated with the Short-tailed bat have developed a colonial social structure with morphological division of labour, and having entirely lost their wings, becoming essentially blind and their vestigial wing muscles serve only to produce angry buzzing sounds when trampled by bats, the larger individuals serving as guards to guide bats away from the arrays of eggs on long stalks that lay dormant while the bats are torpid and hibernating while their parents die off. If the tree is damaged or falls, which it often does the bat colony will usually seek a new home, and since the Batflies have absolutely no means to find a new colony on their own their only option for transport is to perform phoresy and have gravid females grip onto the bats' fur at all times ready to move in when they're active in case they don't come back. Usually they live in very hot, humid conditions in bat guano which made it interesting for the researchers- they had to keep them in tupperware in their airing cupboard to keep them alive and I bet they smelled something fierce.

Excellent educational content. We had a crew top six birch that were between 50-60ft, and until now, I wasn't aware of the consequences. I take full responsibility--I should have done my homework, but instead put blind trust in the crew to inform their customer. It's definitely a pro-con situation as we needed more light on our property to help smaller species grow, and reduce birch growth and leans without costly ($$$$) annual visits. We'll put together a plan to maintain what we have as economically as possible, while thinking about planting new saplings in adjacent areas of mature trees that might decay.

[@takingafatdump]

if you can, get an arborist out soon to tell you if the trees are this bad, because there are ways to stop it especially if you catch it early. good trimming can definitely thin out the trees so you can have more light. just make sure it’s a licensed arborist with a good reputation. lots of cities actually have them on staff or if not, may be able to point you to a good one for residential property. like the second tree in this video, with proper maintenance, you can save them.

Nice post. Trees in a domestic setting can often give rise to 'issues'. 'Wrong' species, wrong place (like the first one; too big, planted too close). But people love them, so a common and understandable response is to try to keep them. Crown reductions done well look 'natural' in very short order as the tree (with the majority of its resources and all of its root system intact) puts on a spurt of growth. It is easy to 'sell' the advantages of a reduction, but less easy to 'sell' the need to do repeated cuts at regular intervals thereafter. I'm in the UK and, as an ecologist, one of my interests is ancient trees. The UK has a large number of these, especially pollard oaks. The kind of rot and holes you point out can have great value as niches for specialised species (bats, beetles, moths, flies) and in the right context, cause little public safety issues. Unfortunately on this crowded isle, houses and infrastructure get built in close proximity to pre-existing trees and the tree inevitably has to give way to 'safety' or the needs of the integrity of the new build. I have seen houses built within a few yards of 350-plus year old pollarded oaks and the pollards later removed. I hope many people see this post and it acts to address some of the ignorance around trees and their care.

It does depend on the species, but as an experienced horticulturalist/ arborist my general rule is to never make cuts larger than 6 inches without very good reason (4 for sycamore, 10 for oak). If you must do it leave an extra 2-3 feet of sprag to die back, it will not look as neat but the tree will be happier in the long term.

i have a question, will the top-cut also rot away if you treat it with the tree-sealant?

[@Phoenixesper1]

Yep. Because the sealant will fail fairly quickly. All it takes is a pin prick for water to infiltrate and with the sealant over it it will trap in the moisture and accelerate the rot then if you didn't use it. Plus the sealants slow down the trees ability to grow over the wound.

[@arboristBlairGlenn]

Tree sealant, also known as wound dressing or pruning sealant, is a substance that is applied to the exposed surface of a tree wound intended to protect the tree from decay and infection. The idea is that by sealing the wound, moisture and other contaminants are kept out, which hopefully might help to prevent decay. However, research has shown that sealing wounds with tree sealant is not necessary, and in some cases, it can actually do more harm than good. For example, in certain species of trees, such as oaks and elms maples and birch, sealing a wound can trap moisture and create a favorable environment for decay-causing fungi. In general, the best approach to preventing decay in trees is to promote overall tree health through proper pruning, watering, and mulching practices, and to avoid damaging the tree in the first place. If a tree does sustain a wound, it is best to simply clean the wound and allow it to heal naturally, without the use of sealant.

Had just the same at a recent job. Customer wanted the sprouts cut off of his Silver Maple. Climbed up it to inspect it because it already had some decay showing. And it was bad. The main leaders already gave some way with just me on them and I was just half way. So came down and discussed the situation with the owner. He really likes the tree and wants to keep it for as long as possible. And there is no immediate danger for personal harm, just material. But something has to be done in the near future. So for this year I hired a spiderbucket and cut off the sprouts. And next time round I'll cut off a decent portion of the main leaders back to sound wood so it can sprout again and the customer can enjoy the tree for some more years. Not the cheapest option, but that is what customer wants. So also a good example of communicating with your customer and explaining the pro's and con's. Just sad that he made the decision in the past to top it.

isn't there like something you can smear over the wound to help the tree heal without forming a cavity? rubber tree sap or something perhaps? seems to make sense it would rot the core if it's exposed to the elements instead of safely inside bark and stuff.. is it really just the fact it was topped, or the fact it's left wide open?

7:22 So is it best for the health of the tree to tear this stuff out if you see it? I bought house last year, and tree was hit by lightning right as I was buying it. Tree had grown from base into 2 large trunks were everything grew from. One side quickly died, but the other bloomed normally in spring, and looked normal all year. I noticed it had started this build up near the base were both trunks split from. It must have died over the winter because nothing bloomed over winter, and small branches on the healthy side are falling off.

Removing the decayed areas does not stop the decay. I often take the soft decay out to better evaluate how sound the wood is.

Wound dressing has been studied extensively by Dr Alex Shigo and his team of scientists and it is now understood that wound dressing does not stop decay or prevent insects. The angle is a theory that makes sense if the wound is in a location that allows it.

We don't have tornadoes (random guess, but I would say maybe 1 tornado every 50+ years), but something else could make that tree fall over, who knows.

Unfortunately the treatments developed for certain species in the kingdom Animalia don't necessarily work on members of kingdom Plantae. It's worth studying how to prevent rotting when trees are exposed like this, and whether clean tools and hands are important to tree surgery. In the meantime it's probably best to just show people this video (and remind them of the other issues with tree topping).

[@momlikesmemore]

I need a book called Trees for Dummies. Should a red oak be topped? The previous owners planted it a foot from the fence line, it annoys my neighbor so over the years he’s been cutting anything extending onto his side of the fence. When you look at it from the side, it looks like a facade of a tree. I’m worried that the weight of it is lopsided and that it could fall onto my house. Should I have it removed?

[@arboristBlairGlenn]

While I don’t like to top trees, sometimes that is the only alternative to removing. The question of right or wrong isn’t even in the thought process. Will topping shorten the life of a tree? Yes, but cutting down kills it altogether. Some species will tolerate a hard cut.

I'm a sustainable food forest manager, if we top of a food tree (on average, say it decays well...) would placing a jar, or bucket upside down on top of the cut aid in healing by keeping water and additional spores out?

Tree sealant, also known as wound dressing or pruning sealant, is a substance that is applied to the exposed surface of a tree wound intended to protect the tree from decay and infection. The idea is that by sealing the wound, moisture and other contaminants are kept out, which hopefully might help to prevent decay. However, research has shown that sealing wounds with tree sealant is not necessary, and in some cases, it can actually do more harm than good. For example, in certain species of trees, such as oaks and elms maples and birch, sealing a wound can trap moisture and create a favorable environment for decay-causing fungi. In general, the best approach to preventing decay in trees is to promote overall tree health through proper pruning, watering, and mulching practices, and to avoid damaging the tree in the first place. If a tree does sustain a wound, it is best to simply clean the wound and allow it to heal naturally, without the use of sealant.

Great work! We, unfortunately run into topper trees constantly. In fact almost every tree that is prunes in the area has been topped instead of having a crown reduction or thinning done to keep it healthy and safer. We had the honor of climbing and doing a restorative pruning job for a massive silver maple in town. It had been topped terribly twice. And topped down to around 20 feet. So we suggested leaving where the wounds were for now and letting them heal as best as they can, but taking all the length off the new growth down to decent laterals. Basically taking the weight off the damaged areas. We never recommend this harsh pruning techniques. Too many people want to sling a saw and not actually learn about the best industry practices.

[@arboristBlairGlenn]

Happy for your comment. You are now part of this community and adding insight to other questions can help others to better understand the mistakes. I believe that the ignorance of the bad practices comes from the owners of the tree companies not caring enough and not training.

[@benheinrich8278]

What about topping younger, specifically fruit trees? That seems to be common practice from a lot of nursery's and guides. Would love to know if I need to airlayer some fresh saplings before they get any worse. Thank you for this very informative video!

[@kellyriddell5014]

Yes, I had the same question. Nut trees too. We're planting pecan trees this year and they can get over 50 feet tall. I figured we would eventually top them, but now maybe I need to do more research.

[@maryl8614]

@@kellyriddell5014 we’ve never cut our pecans, except some light thinning of lower branches. They do great as they are, and we usually just shake the limbs (or send a kid up to shake the limbs) and then collect the ripe pecans from the ground. It also depends on the type of pecan- if you got pure native pecans, then they’ll be taller. If you got some bred for nuts, then they’ll be shorter with a nice, friendly arbor.

[@maryl8614]

For fruit trees, they come pre-cut from the nursery (or catalogue) when you buy them, so you have to trim them because they’ll sprout every year. Once something has been trimmed, you can’t get it back to its “natural” state (no crazy sprouting). For fruit trees, this is generally ok because 1) they’re short (comparatively) and 2) regular trimming produces more sprouts with buds, as he shows in the first part of the video. You want that branching for more fruit, and you can coax it into the best shape for your tree. We tried a few years of not trimming our pears and apples, but didn’t get good results.

[@kellyriddell5014]

@@maryl8614 Thank you for sharing that information! We have a mature mulberry tree already and we have a big hook tool to shake the limbs. Hopefully that will work for the pecans, too. They're young trees so I have years before I get to enjoy trying to harvest them but I'm brand new to nut trees so I'm trying to figure out the best way to care for them before I get to that point.

[@Hydrantchan]

In the case of fruit and nut trees, you wouldn't be topping them like this when they're adult trees, but would rather trim them when they're younger to encourage horizontal branch growth - like another comment said, if you're getting them from a nursery they'll already have taken care of that

[@HawtDigg1tyDawg]

I've always been told that after you've topped or pruned any type of shrub or tree you MUST do an additional angled cut so that water cannot easily pool on it. Does this slow or stop rot in your opinion?

I have seen so many angled cuts as decayed as can be. Does the angle slow down the decay? I don’t think so but the theory makes sense.
