Growing conditions can affect earliness of production. Trees that are planted in good soil with adequate moisture, good weed control and not overcrowded will start producing at an earlier age than trees growing in more stressful conditions. 

A grafted pecan tree 4 to 6 feet tall planted in a good site and properly maintained will generally begin production in 6 to 7 years. The more precocious varieties may sometimes start production in 4 to 5 years. The less precocious varieties may take 8 to 10 years to bear. 

Non-grafted seedling and native pecan trees often take 10 to 15 years to begin production. Following are the varieties that can begin producing early if given adequate care and growing conditions.
