Various specially made injectors are also available for this purpose if you need to treat several trees. What that does is stops the flow of water/nutrients which is essential for photosynthesis.

How do I kill a tree without peeling it or cutting it? With the supply of nutrients cut off thanks to ring barking, the roots die, and the rest of the tree quickly follows due to lack of water. With no water flowing upward through the xylem (even though the xylem remains intact), the leaves will dehydrate and die. Checking this will help, and, "Yes, this helped and saved me money. Girdling for fruit production is a frequently used technique on peach and nectarine trees. Girdling is commonly used on grape, avocado, apple, litchi, mango, citrus and other trees.

Tree girdling roots is commonly caused by improper planting, like piling too much mulch up against the tree trunk.

To understand the circumstances that allow this to occur (i.e., stripping bark around the entire circumference of a tree), it's important to dive deeper into the differences between xylem and phloem. The proper name for "water transportation in a plant" is "transpiration."

It is a delicate procedure that doesn't seem to work on all trees but may work on peach trees in particular, according to Gardening Know How. In other words, water goes where it's lacking, and it's always lacking in the leaves due to evaporation through tiny holes in the leaves called stomata. Most likely yes.
