Overview

The English walnut tree is a large, slow-growing deciduous tree that produces walnuts in the fall when it's 3 to 7 years old. The English walnut tree makes for an excellent shade tree in your landscape, due to its dense foliage and large size, growing up to 60 feet tall at maturity. Plant your English walnut tree in full to partial sunlight, where the soil is fertile and has good drainage. When planting your English walnut tree, work generous amounts of organic compost or aged manure into the soil to boost its fertility.

Step 1

Water your English walnut tree once or twice each week in the summer. Water the tree deeply, soaking the soil down to the root zone.

Step 2

Spread a 1-inch layer of organic compost or aged manure around the base of the English walnut tree each spring. Spread a 2-inch layer of bark mulch on top, keeping the mulch 1 to 2 inches away from the trunk.

Step 3

Prune the English walnut tree to a single main trunk when the tree is young.

Step 4

Cut away any dead, damaged or diseased branches every fall, after the nut harvest. Prune away all crowded or crossing branches from the English walnut tree as well.

Step 5

Harvest the walnuts when the green hulls begin to split open in late autumn. Remove the nuts from the hulls, dry them and store them in an airtight container.

Tips and Warnings

  • Don't over-water your English walnut tree because this tree is susceptible to blight and other fungal infections when it remains too wet. If you're experiencing moderate to heavy rainfall in the autumn, stop watering the tree completely.
