I saw this at a park while I was in China. Our guide told me it was an IV for transplanted trees. If you can tap a tree for sap I see no reason you cannot inject needed nutrients and moisture by lifting the solution above the tap. I was just wondering if anyone out there knew anything about this. I loose a lot of transplants because I am unable to water them while I am away from my BOL.
I have never seen or heard anything like this. What an interesting idea. Is it injected into the tree right at the bag? I see a tube running down. Or are the nutrients put into the ground?
But I think this is what you need... It's like a needle from the Witch Doctor , only for trees... https://www.amazon.com/dp/B005VY25SU/?tag=survivalmonke-20
That looks like the idea except using pressure to force the liquid into the tree. Gravity would work as well, IMO, just not a fast. @Motomom34 it was being injected into the tree not the ground.
