How to Grow a Peanut Tree

The peanut tree (Sterdulia quadrifida) is a tropical tree, native to the rain forests of Queensland and New South Wales in Australia. It makes a lovely shade tree, and produces bright orange seed pods that contain edible seeds. The peanut tree grows quickly to an eventual height of 50 feet. Known as a semideciduous tree, it does not tolerate frost, and may, or may not, lose its leaves in the winter. The peanut tree is easy to grow from seed, started indoors.

Things You'll Need

  • Pot
  • Potting soil
  • Bucket or bowl
  • Compost
  • Shovel
  • Stake
  • Plant ties
  • Cage


    • 1

      Fill a pot with moist potting soil, and push the peanut tree seed 1/2 inch into the soil. Cover it, and place the pot in a lightly shaded area.

    • 2

      Keep the potting soil slightly moist, and don't overwater it. The seed should germinate within four weeks.

    • 3

      Keep the seedling growing in indirect sunlight, in moist soil, until it can be planted in the garden in the spring.

    • 4

      Place the potted seedling in a bucket or bowl, and add water until it reaches within 1/2 inch of the rim of the pot. Allow it to remain in the bucket or bowl while you prepare the planting site.

    • 5

      Dig up a 1-foot square and 1-foot deep area of the garden in which you will plant the peanut tree. Add 4 inches of compost to the removed soil, and blend it well. Replace the amended soil to the planting site.

    • 6

      Create a planting hole twice the diameter of the pot in which the peanut tree is growing, and the same depth. Remove the seedling from the pot, and place the roots in the hole. Fill the hole with soil until it is half full, and then fill it with water. When the water drains, finish filling the hole with soil. Use your hands to firm the soil around the base of the seedling.

    • 7

      Insert a stake into the soil, 6 inches from the seedling. Use soft plant ties to loosely tie the seedling to the stake.

    • 8

      Water the tree after planting until the water puddles, then water it once a week if there is no rain.

    • 9

      Place a chicken wire cage around the peanut tree seedling to protect it from predators. Cages can be purchased at gardening centers, or you can make your own by pounding stakes into the soil around the seedling and wrapping wire around the stakes, using wire to fasten it to the stakes.

      Fertilize the peanut tree by adding a 3-inch layer of compost to the soil every spring.
