what is the life span of a pecan tree
Trees grown from seed usually bear their first crop at 10 to 14 years of age and reach full maturity at 18 to 22 years. Trees grown from a graft can bear their first crop at 6 to 8 years and reach full maturity at 14 to 16 years. The life span for pecan tree, either seed or graft, is about 40 years.
