Pecans have 0.0917431 grams of protein per gram of pecans.
Allow for approximately 65 to 80 feet (19.81 to 24.38 m) spacing between each pecan tree that you plant. If trees are crowded, the faster growing tree will over-shadow the slower tree, stunt it, and kill it eventually, hampering both trees' crops. Pecan trees take 20 to 25 years to mature. Some growers will plant trees 30 feet apart, and remove half the trees at around 15 years, when they begin to crowd each other.
