You can without much of a stretch prune your walnut tree. After your walnut trees grow for 1-2 years, prune them so their shape begins to take the structure and their appendages develop and create. Train your tree into the focal pioneer shape, which is the point at which the tree has 1 primary trunk with 4-6 parallel branches.

Cut off low-hanging, feeble, or harmed branches, and dispose of any branches that rub against one another. At that point, to achieve the best trimming walnut tree, keep pruning your trees every 3-5 years as they develop.

With customary support, you can keep your trees healthy, dispose of contending branches, and augment their growth potential. 

1. Prune the tree when it is 1-2 years of age into the focal pioneer position. After around 1-2 years of growth, your walnut tree ought to have its essential structure. It ought to have a few reasonably thick branches and be around 4–6 ft (1.2–1.8 m) tall. Now, you can start forming the tree into the focal pioneer position. The focal pioneer position ordinarily has 1 principle trunk with around 5 branches as an afterthought.
   The focal pioneer position depends on the common growth of the tree, concentrating on the fundamental head branch that keeps the overhang of the tree open to light and air course.
   The focal pioneer causes supply supplements to the enormous, organic product bearing branches so the tree grows whatever number walnuts as could be expected under the circumstances. 
2. Leave 1 primary branch at the highest point of your tree and evacuate the rest. The branch at the top is your “focal pioneer,” which keeps the highest point of your tree open and breezy. In the event that you see extra branches growing towards the top, clip them off with nursery shears or saw them away utilizing a hand saw.
   Along these lines, your tree can guide every one of its supplements to this highest branch. 
3. Remove branches are thicker than ⅓ of your trunk’s thickness. When pruning walnut trees, watch the “3-to-1 standard.” Examine the thickness of your trunk, and utilize this as a guide when choosing which branches to keep and which to expel. On the off chance that you discover a branch bigger than ⅓ of the storage compartment’s distance across, cut it off at a 45-degree point. Thusly, your branches will all get a decent measure of supplements and grow healthy and solid.
   In the event that your tree has more than 1 thick branch, at that point it will be more enthusiastically for different branches to grow and create walnuts. On the off chance that you keep branches that are on the thicker side, they can unevenly empty the supplements out of the tree and grow excessively thick. 
4. Cut off any forked branches either into a solitary shoot or at the storage compartment. A forked branch is a shoot with a part in the branch, making 2 branches grow from the fundamental branch. These branches require more supplements from the tree, and they frequently go about as bloodsuckers from different branches getting crucial supplements. To avert this, you can either cut off 1 side of the branch to make a solitary shoot, or you can remove the branch entirely.
   The two alternatives will enable your tree to all the more likely moderate supplements.
   On the off chance that you as of now have numerous satisfactory branches, you may need to just evacuate the branch totally. In the event that you have a couple of inadequate branches, trim off the littler of the forked sides.

These steps can guarantee the best trimming walnut tree, so take them in consideration when planning to work on your trees.
