Pecan trees serve both as home landscaping trees and as food production. The time to maturity depends on a number of factors, and some trees may never produce quality nuts if not cared for well.

A grafted pecan tree can produce a small crop as soon as two years after its grafting, although it will typically take closer to five years to mature enough to produce a large crop. Some pecan trees may take 10 to 12 years to move beyond vegetative growth into fruiting maturity.

The exact time to maturity for any given pecan tree depends on a number of factors. These include the climate, how much sunlight the tree receives, soil quality and the presence of another tree for increased pollination.

Pecan trees can grow to 70 feet tall have trunk diameters of 6 feet at full maturity. Trees can be spaced as close as 30 to 40 feet apart until they are about 15 years old, at which point they should be thinned. At 30 to 40 years old, pecan trees grow to a width of closer to 60 feet.
