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.
With their spreading habit and sweet-fleshed nuts, pecan trees (Carya illinoinensis) serve a dual purpose in landscaping as both a shade tree and edible crop. The trees prosper within U.S. Department of Agriculture plant hardiness zones 5 to 9, where they will put on 2 to 3 feet of growth each year.ecan trees grow reliably well from seeds, although you must chill them for two to three months before sowing to satisfy their dormancy requirements. Once chilled, sow them in deep pots and provide them with constant moisture to successfully germinate them one month later.
