Answers.comÂ® is making the world better one answer at a time. A pecan tree can start producing pecans anywhere from 4 to 10 years if they are grafted. Ungrafted trees can take 10 to 15 years before producing pecans.
If you want to add a pecan tree to your landscape, start with a container-grown or bare-root nursery tree, or grow your tree from seed. Although pecans planted from seed grow slowly during their first two to three years, they can easily reach heights of 70 feet or more at maturity, around 20 years of age. For best results, you'll need to graft your seed-grown tree at the proper time, in addition to planting a second variety for cross-pollination.
