Pruning is a horticultural and silvicultural practice involving the selective removal of certain parts of a plant, such as branches, buds, or roots.
What You’ll Need
Step One: Decide When to Prune
Pruning is best done in late winter or early spring before new growth begins. However, if a limb is dead, diseased or damaged, it can be removed at any time.
Step Two: Sharpen Your Tools
A pruning saw and sharp pruning shears will make the job easier and prevent damage to the tree. Make sure your tools are clean to prevent the spread of disease.
Step Three: Remove Dead, Diseased or Damaged Limbs
These limbs should be removed as soon as possible to prevent the spread of disease or insect infestation. If more than one-fourth of the canopy is dead, diseased or damaged, seek advice from a certified arborist before proceeding.
Step Four: Select Structural Branches
The main structural branches of the birch tree should be evenly spaced around the trunk and angled outward at a 45-degree angle. These branches will provide support for the tree as it grows and should not be removed.
Step Five: Remove Crowded or Rubbing Branches
Crowded branches can lead to weakness and breakage, so they should be removed. Branches that are rubbing against each other should also be trimmed back to prevent damage.
Step Six: Cut Back Suckers
Suckers are small shoots that grow from the base of the tree or from along the trunk of the tree. They compete with the structural branches for resources and should be removed.
Step Two: Prune the Canopy
The goal is to create a strong central leader with evenly spaced side branches. Begin by pruning away any dead, diseased, or dying branches. Next, remove any branches that are crossing or growing inward toward the center of the tree. Once you have removed all the unwanted growth, you can begin to shape the canopy by pruning away the tips of the longest branches.
Step Three: Cut Back the Suckers
Now that the main branches have been cut back, it’s time to tackle the suckers. Look for small, thin shoots that are growing vertically from the roots or lower trunk of the tree. Suckers are generally lighter in color than the rest of the tree and they don’t produce leaves. While it’s okay to have a few suckers, you’ll want to remove any that are growing more than a few feet tall.
To remove a sucker, use pruning shears to cut it as close to the ground as possible. If the sucker is too big to cut with shears, you may need to use a saw. Once all of the suckers have been removed, your birch tree should be ready for growth in the spring!
Step Four: Remove Dead or Diseased Wood
fourth and final step is to remove any dead or diseased wood. This can be done by using a saw to cut away any branches that are not healthy. You should also remove any suckers that are growing from the base of the tree.
Step Five: Shaping and Thinning
Shaping and thinning are two different pruning cuts that should not be confused. Shaping is done to control or direct the growth of the tree, while thinning is done to increase air circulation and light penetration, and to reduce the weight of heavy branches.
When shaping a young tree, prune branches back to a lateral branch that is at least one-third the diameter of the branch being removed. When shaping an older tree, prune branches back to a lateral branch that is at least half the diameter of the branch being removed. When thinning a birch tree, prune branches back to the trunk or to a main lateral branch. Remove no more than one-fourth of the live branches when thinning.
Pruning is a vital part of maintaining a healthy birch tree. By pruning your birch trees, you are ensuring that they will continue to produce beautiful, lush leaves year after year. With the proper care and attention, your birch trees will thrive for many years to come.
