Palm trees are unique in that their roots don't grow straight down; they grow horizontally. Typically, palm tree roots go down between 12 and 36 inches deep. The roots grow far and wide from the base of the palm tree to absorb as much water and soil nutrients as possible. In addition, the horizontal roots are also very strong—keeping palm trees stable and helping them sway during storms.

Licensing requirements for arborists, also known as tree surgeons, vary by state and municipality. Many areas require a license, which often involves specialized education and experience. Even if not mandated, it's wise to hire a licensed professional as they tend to have more experience. Beyond licensing, look for certifications from organizations like the International Society of Arboriculture (ISA) or the Tree Care Industry Association (TCIA), as this indicates a higher level of expertise. Certified arborists must typically pass a comprehensive exam. Always confirm that the arborist has a business license and is fully insured to protect yourself from liability. Seeking positive recommendations from local homeowners is also a good step in finding a qualified professional.

The best time to prune Japanese flowering cherry trees depends on where you live and the type of flowering cherry tree. Some trees benefit from being pruned toward the end of winter or early spring, after the last freeze. Meanwhile, other trees do well after blooming, in late spring or early summer. Avoid pruning your flowering cherry tree in the early winter, as this encourages open wounds that can lead to infections or infestations. 

Transporting a fully-grown tree requires heavy equipment, typically specialized for the task. A tree spade is a truck-mounted tool that removes the tree from the ground in one location, transports it, and places it in a new hole in a new location. A combination of mechanized shovels and lifts is necessary to move very large trees, and the exact tools often depend on location and the surrounding area.
