The largest tree that was transplanted was the Yonggyeri Ginko, a 750-year-old gingko (Gingko biloba) tree measuring 29 m (95 ft 1.73 in) tall, 33 m (108 ft 3.21 in) wide (wingspan), with an estimated weight of 1.250 metric tons (2.75 million pounds) and with a trunk circumference from 13 m (42 ft 7, 81 inches). Transplanting a large tree from the field to the garden provides immediate shade, a visual focal point and vertical interest. Although the effect is much faster than waiting for a seedling to grow, the transplant does not happen overnight, so plan well in advance when you are going to transplant a large tree. Smaller trees can be moved with a tree shovel, a device that can dig the new hole, as well as excavate and transport the tree.
Larger trees may require digging, wrapping, or wrapping the root ball and then transporting it by truck. Some trees can be moved with cranes. First, the teams excavate a large area around the tree and create what is called a “root ball” by attaching the root system of the tree with burlap, wire and plastic. If the tree needs to be removed but cannot be replanted immediately, it will be necessary to place the root ball in a box and the tree will need to be stored somewhere and watered.
A representative of one of those companies once told me: “You can move any tree, as long as there is an unlimited budget. Similar cases can be cited until the 1970s, when the development of hydraulic techniques increased the movement capacity of larger, heavier trees, Cox said. Then dig a trench around the tree forming a circle the right size for the root ball of the tree. Most companies that specialize in moving trees provide detailed aftercare instructions and will not guarantee any tree moving work if aftercare is not provided exactly to your specifications.
For example, a 12-inch (305 mm) diameter tree at the base requires a hole at least 10 to 12 feet (3 to 3.6 m) wide to preserve roots, plus a little more room to pull out and enter the tree. Anyone who has followed the introduction of Dutch elm disease (DED) is already painfully aware of how devastating outbreaks of tree pests can be. The key to successfully transplanting a large tree is to help the tree grow roots that can travel with it to its new location. In the 1920s, William Randolph Hearst moved giant oak trees to make room for structures on the grounds of his castle in San Simeon.
Trees should be monitored for moisture level and fertilized to ensure they thrive. Root pruning encourages new roots to appear near the tree, within the area of the root ball that will travel with the tree. That is the situation the city of Buda found itself in when it realized that a 260-year-old heritage oak was standing in the way of its planned site for a new municipal complex on Main and East Loop Streets. If you are considering moving a tree of any size, work with a company that specializes in this process.
