Description
Pecans are commonly grown for their edible nuts and for their wood, which is highly prized for furniture. They are also very useful in permaculture projects because of their deep root systems and ability to fix nitrogen in the soil. The pecan tree does this with the help of beneficial bacteria that live in the soil and convert atmospheric nitrogen into a form that is readily available to the plant. In return, the bacteria obtain access to sugars and other nutrients produced by the tree through photosynthesis. This mutually beneficial relationship helps to improve soil fertility and structure, which in turn can help to increase the productivity of other plants. In addition, the deep roots of the pecan tree can help to reduce soil erosion and improve the water-holding capacity of the soil, which can help to mitigate the effects of drought.
Growing Details
Soil should be deep and well drained. The soil should have a pH between 6 and 6.5. Pecan tolerates summer heat very well and it requires long and hot summers for good fruiting. Seedlings can bear fruits in 5-10 years from planting, but grafted cultivars can start fruiting in as little as 3-4 years.

Uses & Benefits
Edible Rating:
(3/5)
edible uses: Pecan nuts are a rich source of energy and contain health benefiting nutrients, minerals, antioxidants and vitamins that are essential for wellness. They are rich source of monounsaturated fatty acids like oleic acid and an excellent source of antioxidants to help remove toxic oxygen-free radicals and thus, protect the body from diseases, cancers, as well as infections.
Medicinal Rating:
(2/5)
medicinal uses: Infusions of the bark have been used in the treatment of tuberculosis. A hot poultice of the leaves has been used as a treatment for neuralgia. The oil from the nuts has been used externally in the treatment of rheumatism. Maple sugar can be used in the treatment of coughs, the syrup is used in the treatment of kidney complaints and as a purgative.
health concerns: Overconsumption may cause weight gain.
other uses: Wood - hard, heavy, durable, close-grained, it takes stain nicely. Used for furniture, flooring, tool handles etc.

Seedlings can bear fruits in 5-10 years from planting, but grafted cultivars can start fruiting in as little as 3-4 years.
Potential Disturbances: Pecan trees encounter ecological pressures from organisms such as pecan weevils, aphids, and stink bugs, which can affect nut development.
