Root-Collar Excavation: Don't Blow It

[@thomaslindroos1667]

How can it become 3000psi from 300 psi? when you decrease the nozzle size the pressure drops but the speed increases. So coming from a big hose into a smaller nozzle the pressure should by all means drop but the velocity of the air will be devastating.

Will the tiny fibrous roots eventually die off if left exposed? I feel like I can't possibly get them all in some cases. And I have about 30 trees to do this to on my property with just hand tools so it's all a bit overwhelming

With a magazine to promote your channel at your disposal, why do you have so few subscribers? I like this video and hope more tree workers see it.

Guys come on now……🧐. Girdling roots are just a small part of the problem. Yes they must be corrected for future health of the tree…..but the bark rot at the bottom if the trunk above the root collar is more of an issue. In your next video…..mention this issue.

Problem here is the tree is a Bradford pear. This thing has seen little too no love.
