How to Plant an English Walnut


English walnuts are large trees known for adding beauty to the landscape and producing a nicely shaded environment. The tree reaches maturity at approximately 20 years. Because they can reach a height of 60 feet, they must be spaced at 40 to 60 feet apart to prevent crowding. Plant your English walnut in the spring after there is no longer a risk of frost. The tree will begin producing nuts at 5 to 10 years of age.

Step 1

Select a planting site that has well draining soil and enough room to provide 40 to 60 feet of space around the tree.

Step 2

Dig a hole twice as wide as the root ball and slightly deeper. Mix an equal quantity of peat moss into the removed soil. Add enough soil mix into the hole so the root ball is set at ground level.

Step 3

Place the tree into the hole and fill in soil around the root ball so the hole is half full. Fill the remaining area of the hole with water and let it absorb into the soil.

Step 4

Fill the remaining hole area with the soil mix and gently pack in place to remove air pockets. Make sure the tree is standing straight.

Step 5

Water the tree deeply after planting to moisten the surrounding soil several inches deep. Continue to water the tree for the first two years of growth with 1 inch of water each week when rainfall is not present.

Step 6

Apply 2 to 3 inches of mulch around the tree, leaving a 2-inch gap between the start of the mulch and the tree trunk. Excess mulch around the trunk will hold moisture that can cause disease to the trunk.

Step 7

Apply composted manure or bone meal around the tree in the fall. Do not apply chemical fertilizers to an English walnut tree, as they are detrimental to tree growth.
