Pecan Tree Information

Pecan trees are native to America and Mexico and grow mostly in Georgia and grows in Florida to Illinois, even to the west of Texas. Pecan trees are rather large, a mature pecan tree can grow up to 40 m tall with a spread of 12 – 20 m. If you’ve large yard you can grow pecan trees as they are not suitable for small backyards or garden. These trees are the source of many medium-sized pecans that are eaten fresh or used to create sweet desserts and candies, including pecan pie, caramel-pecan tarts, pecan pie, pecan pralines and many others.

Planting Pecan Trees

  2. Space candy pecan no closer than 40 feet (if planting in a garden). For planting pecan trees in orchard, a suitable distance is 40 – 50 feet.
  3. Grow at least two pecan trees to ensure that most of flowers produce nuts. Although self-pollination in candy pecan is possible, but it is preferred that at least two or three trees are planted nearby for maximum nut production.
  4. For planting pecan tree, dig a hole at least 2 feet wide and 2 feet deep as pecan trees have extensive root system. Fill the hole with well-drained soil. Pecan trees can generally be grown easily and efficiently in a variety of soil types, except the soil which drains poorly.
