Im about to finish my landscape and I hit a snag, I got trees that I want to keep but the dirt around them got to go up about 12".
Now is it possible to do without killing the trees, and how to do it.
Hello, in answer to your question, you cannot directly raise the soil around the collar of the tree as this will cause the tree to die, however you can create a retaining wall, 3'-5' away from the trunk of the tree, using stone, concrete blocks, decorative concrete wall material or any other retaining wall product of your choosing to keep the ground at the same height while raising the ground level everywhere else on your property by 12".
My first question would be, how big are the trees? If they are smaller/ ornamental you may be able to dig them up and transplant then at the new grade. Early spring or late fall are the ideal times as the plants are in a dormant state.
If transplantation is out of the question, a terraced option like the above suggestion would work.
Finally if its feasable you may have to add a step or two to get to the lower gradient.
The second response you got is the one that will work for you. I am assuming the yard is pretty much level. If you have interlock in the front of the house then use that. If not, may I suggest using 12" high pieces of ledge rock. It will give it a great look. Remember to install landscape fabric on the inside of what ever retaining wall you build.
I have never seen a tree that does not like water. This will provide more when it rains.
