Two trees may grow to their mature size adjacent to each other and seemingly grow together or conjoin, demonstrating inosculation. These may be of the same species or even of different genera or families, depending on whether the two trees have become truly grafted together (once the cambium of two trees touches, they self-graft and grow together).
Tree stump, about 37 years after falling. After a tree has been cut and has fallen, the stump or tree stump is usually a small remaining portion of the trunk with the roots still in the ground. Stumps may show the age-defining rings of a tree. The study of these rings is known as dendrochronology. Stump sculpture by German artist Eberhard Bosslet
Girdling prevents the tree from sending nutrients from its foliage to its roots, resulting in the death of the tree over time, and it can also prevent flow of nutrients in the other direction depending on how much of the xylem is removed. A branch completely girdled will fail; and, when the main trunk of a tree is girdled, the entire tree will ...
But other parts of the tree are now growing back healthy. How was it saved? Those working to restore the tree removed the dead branches so that the tree's energy would go toward the branches that ...
Some trees may be rejuvenated by pollarding – for example, Bradford pear (Pyrus calleryana 'Bradford'), a flowering species that becomes brittle and top-heavy when older. [citation needed] Oaks, when very old, can form new trunks from the growth of pollard branches; that is, surviving branches which have split away from the main branch naturally.
They also prune the trees at least once a year to ensure they grow with a perfect shape and full branches. This meticulous care is what helps transform a simple sapling into a stunning holiday ...
Most artists use grafting of living trunks, branches, and roots, for art or functional structures and there are plans to grow "living houses" with the branches of trees knitting together to give a solid, weatherproof exterior combined with an interior application of straw and clay to provide a stucco-like inner surface.

Coast redwoods can also reproduce asexually by layering or sprouting from the root crown, stump, or even fallen branches; if a tree falls over, it generates a row of new trees along the trunk, so many trees naturally grow in a straight line. Sprouts originate from dormant or adventitious buds at or under the surface of the bark.
