How to Grow Walnut Trees in Your Garden


Planting Walnut Trees:

  • Till a 12 square foot area to at least 10 inches in depth and be sure to remove any grass, weeds, or other plants that may impede with the walnut tree's growth.
  • Then, dig a hole that's about 1-2 inches wider than the walnut seedlings' root ball.
  • Place the seedlings into the hole and bury the roots 1 to 2 inches below the soil. Fill in the hole and tamp down to eliminate any air pockets.
  • Water the tree until moist but not soaked.
  • Mulch the surrounding area with organic mulch to retain moisture.
  • Be sure to keep the mulch about 2 inches away from the new tree.

Caring for Walnut Trees:

  • Because of their extensive root system, walnut trees do not need much water.
  • Only water if the top 2 inches of soil are dry.
  • Prune any dead or damaged limbs as the tree matures.
