How Trees Grow The buds, root tips, and cambium layer are the three growing parts of the tree. Buds elongate the branches and widen the crown (branches and leaves), the cambium layer adds diameter to the tree, and the root tips grow in length to support the growth of the tree.
First, refine your notion of fast growing to a growth rate of 1Â½ to 2 feet per year. Or, as Warren Roberts, longtime superintendent of the UC Davis Arboretum, puts it: A fast-growing tree is one you can sit in the shade of, five to six years after planting.. Keep in mind that most trees grow fastest when young and when planted in soil that supplies optimum moisture and nutrients.
