Now, when harvest time comes, a nut tree can produce up to 50 pounds of nuts. Walnut farms start with native pecan tree roots and nourish them for several years until they reach maturity. Pecan trees can reach 60 feet in diameter, so if you want to plant pecan trees on your property, you'll need a lot of space. These trees will eventually grow 60 to 80 feet apart, and a mature nut orchard will have seven nut trees per acre.
The Stahmanns planted 4,000 acres of pecan trees in 1932 and have grown to more than 180,000 trees, producing between 8 and 10 million pounds of walnuts per year. Walnut cake is a traditional American holiday treat, while walnuts are also used to make chocolates in New Orleans. If you're growing a pecan orchard and want to make a profit, you probably want to use a fertilizer containing ammonium sulphate, which most walnut farmers usually accept as the right fertilizer. And several years later, when their son planted 2,000 acres of walnuts in Australia, the Stahmanns became the world's largest walnut producing family.
Pecans also require twice as much water as corn, so nut producers supplement natural rainfall with irrigation.
