Thank you, that helped me alot.😀
My ex killed my trees with a string trimmer!
Brilliantly helpful and enjoyable videos -thank you! A probably silly question - is pea stone the same as pea gravel?
This is not work that should be done b ",ost people" but rather an Arborist and an AirSpade® or an AirKnife® are the tools of choice Using manual tools guarantees root damage. When you insert your manual tool, you cannot see if there are any roots and once you connect with a root, the damage is done.
I love your dry sense of humor. Thank you. I just planted my first tree, and it would break my heart if it died, so I've been doing a lot of research on how to water correctly.
And it won't kill the tree moving forward? I man it's CLOSE to the trunk and you are usually not supposed to remove roots larger than 2 inches.
When you go to the supermarket, go the bakery department and ask for the frosting buckets. They are free and empty. Around three gallons sometimes. Cut holes in bottom and fill with water. Or cut bottom and place next to tree or bush and fill with water. Actually, if you want your roots to grow in every direction,,place more than one bucket next to tree. When watering deep, you can skip a few days.
Sharon: I LOVE THIS RECOMMENDATION! Being mostly Scottish, I appreciate anything thrifty and really appreciate any efforts to reuse materials. Thanks so much for joining all of the comments and recommendations.
I realized something myself- to stake my trees in line with the prevailing winds, I just looked up my local runways at nearby airports. The runway numbers indicate the heading (just add a 0). And there u have the exact spots to stake your trees!
How frequently should water in the winter? (Colorado)
I took aboriculture from him 20 years ago. That started my love affair with trees. I've planted at least 2000 since then.
Give this man a raise.
I wish i had seen this video 3 years ago. Ive got a dead elm with an identical stem girdling root.
You didn't discuss what your expectations were for this particular tree by making such a cut.
I can't for the life of me find where to buy the high impact plastic option. Anyone have a link they can post?
I really like the hard plastic water device I have been looking to get them. I cant find them. I googled high impact water and i am not having any luck. I wish he gave more info for that one. My trees are not near a hose. Im looking for a solution.
They are all weak because of the geoengineering. See Geoengineering Watch. nano aluminum clogging cambiums, soil acidity, dessicant effects, etc.
Diagnosis the tree with stem girdling roots. Fails to mention the gaping hole pretty much at eye level. 9:45
Thank you - very informative and to the point.
I assume "stem" means "trunk"
Can u also stake bushes? I have some bushes that are starting to fall over. I think from the high winds in my area. Can I stake it similar to a tree?
Nice boots... Whites?
I'm starting to plant quite a few trees to try and establish a new woodland and this was extremely helpful. Many thanks and all the best from Greece.
Where can I get the tubes for my trees
Exactly the video/answer I needed. Thank you, sir
perfect vid, thanks!
This professor is funny. I think hungry rabbits will chew through paper too
Gary Johnson you were my Professor at UMCP IAAA in 1990! Wow Looking good Gary hope all is well. Adam Jones Thanks for the helpful post. Obviously I'm still at it!
Grateful for you all sharing your experiences with the whole 🌎 Dropping critical information for a brighter future.
Knowing all these ways to water is extremely helpful, cool.
You take a 5 or 6 gallon bucket. You drill a 1/16 hole in on one side of the bucket. You fill the bucket up to the very brim, and your tree will get that water at its trunk over the course of an hour. Make sure the side of the bucket with the hole in it is the side against the tree.
The flare clearing work was done well. Pretty much in line with the standard procedure in the root management standard. And the editing was very well done! The root is still girdling the stem. A cut could be made just beyond the point of grafting, using a chainsaw and then a chisel. It would be good to review the literature before delving into unfamiliar practices! The July 2007 edition of Tree Care Industry magazine shows some examples of removing embedded portions, like the one left in this video. And the proceeds of the third Landscape below ground conference has a peer reviewed protocol at the very end. If there are any questions or comments about these two references I would be happy to answer them.
Hi, i’m interested in learning more about the two references you mentioned. Do you have pdf versions of the articles?
Looks great!!!
So in 20 years when all the ash are dead will the eab die out? Could ash be planted again at that time?
EAB will probably persist in the landscape on ash that regenerate in the landscape naturally. There may be EAB resistant native ash trees discovered and released in the future - similar to Dutch elm disease resistant cultivars.
wonderful introduction.
This guy, man. EVERYONE that works with trees should be forced to watch all his videos. It would've saved me a lot of money and frustration from incompetent planting-expert geniuses that worked on my property
Thank you for the presentation 🙏
Thank you Kaitlin! Great study. We are struggling with how to help preserve trees on private property here in Sandy Springs , GA
From my experience as a horticulturist air spading and removing stem girdling roots. I like to stay under 25% root cuts or less of the DBH of the tree. I also stay away from cutting roots that have grafted to the tree. That root I cannot tell but seems to be grafted possibly and is huge for the DBH.

Help, where to buy plastic tube ring?
Help, where to buy plastic tube ring?
How often do you fill buckets if you choose this method and am curious why it doesn't cause root rot?
In most cases and in normal summers with a soil that drains well, two to three times a week. If the soils drains slowly, maybe only once a week...you kinda need to experiment a bit by conducting a percolation test (referred to earlier in these notes) and by digging down into the soil near the roots to see if the soil is moist. If your area is experiencing a very rainy season, you may only need to water once a week or two. Root rot is caused by a fungal pathogen that moves with surface water that runs down a slope. So, the pathogen must be present, and there must be vulnerable plants down slope. Quite realistically, root rot is more of a problem in production tree/shrub nurseries and is not very common in landscapes...thank goodness.
I really appreciate your mention of research proven methods. It is clear your experience and success was gained respecting simple scientific method...along with the obvious years of your own trial and error. It's clear there is a lot of misguided advice out there you even went over a few examples of methods that have been proven wrong regarding remedies of containerized root bound trees. That birch example really imprints the importance of how important fixing those roots is! Thank you for sharing the "boxing" method and the confirmation of its success. I actually found your video after reading the Connecticut CAES Tree Owners Manual. It mentioned the importance of pruning any circling/encircling or "girdling" roots, not being familiar with the term I did a google search and wound up here! Glad I did as everything you go through is mentioned almost exactly in the manual albeit much more vague. This video was the in depth guide I needed to see! The manual also reiterates of the importance regarding removing any soil over 1" above the roof flare or subtracting the measurement from the hole depth. I never knew how important proper hole depth is, boy is that root collar depth important. One other thing I found interesting was the mention of roughing up the walls of the hole if soil glazing is present. Never knew what that was until today! I'll be planting 10x containerized "Thuja" Green Giant variety Arborvitae soon and I wanted to thank you for this video. I plan on doing the drainage test in the manual and submitting soil samples to our local lab for a "Morgan Soil Test". Be interesting to see if any amendments will be needed or recommended. Having a green thumb really is just as much of an "art" as it is a "science". All the best & wish me luck!

Interesting insights. Thank you!
