Clear Spacing
Trimming a dwarf weeping cherry tree requires clear spacing to maximise the tree’s growth potential. Dwarf weeping cherry trees have a single trunk and their size ranges from five to six feet in height. Pruning helps to create an appropriate lawn and garden view for outdoor landscaping and provides structural strength for the tree. The most successful pruning is done in small sections over three to five years, versus trying to cut significant portions of the tree in one season.
When pruning a dwarf weeping cherry tree, start by removing all dead wood and any broken or damaged branches before adding any structural branches. Dead wood may be identified easily by its brown, brittle condition, while healthy wood is still flexible.
Remove branches that are closely spaced or rubbing against each other. Prune branches that are growing towards the centre of the tree and any branches that are growing downwards. Additionally, remove any crossing branches that may look attractive while they’re young, but will become cumbersome and dangerous when the tree matures.
To thin the canopy of a dwarf weeping cherry tree, carefully prune back longer branches to keep the desired size. Cutting back larger branches can also help to slow the growth of the tree and direct new branches outward and upwards. Additional pruning should be done during the summer months, when new shoots are forming.
Creating a Formal Look
The purpose of formal pruning is to create a canopy with symmetrical branches from the top to the side of the tree. This will give the dwarf weeping cherry tree its desired shape, as well as promote even growth patterns. Formal pruning should take place during the winter months or early spring when the tree is fully dormant.
Formal pruning should begin at the top of the tree and work downwards in small, steps compromising of short, safe cuts. A sharp pair of pruning shears should be used for smaller branches. For larger branches, use a pruning saw. Direct growth of the canopy by consciously determining where to cut the branches. If a branch crosses over another branch, cut it away to create an even shape.
This kind of pruning will stimulate new growth at the points of the trim, so be sure to make the cuts at areas that are conducive to the desired shape. Once the dwarf cherry tree has the desired form, continue to prune it by removing any new branches that deviate from the predetermined shape.
Safety Considerations
As with all pruning projects, safety considerations should be taken into account. Before climbing into a cherry tree, look for exposed wires, bees or other elements that may disrupt the pruning process – or be potentially dangerous to the operator.
When climbing, use a quality ladder that is tall enough to reach the desired height. Make sure the ladder is securely angled against the trunk of the tree. Wear leather gloves and protective eyewear to protect from cuts, scrapes and splinters.
Using a power saw requires extra caution. Always read the manufacturer’s instructions before using a saw and plan out the area of work before making any cuts. Have an assistant to supervise from the ground and support the branch from beneath.
Keeping the Tree Healthy
Pruning can be damaging to a tree and should be done as infrequently as possible. After pruning, dwarf weeping cherry trees require extra care to encourage new healthy growth. Keep the tree well-watered, especially during dry spells, and fertilise with a slow release fertilizer twice a year.
Provide mulch to lock in moisture around the tree’s roots and use insecticidal soap on the branches to protect against invasive pests. Check the tree regularly for signs of damage, such as blight or disease, and take prompt action if anything is noticed.
Closing Open Wounds
After pruning a dwarf weeping cherry, wounds should be closed and sealed with a special paste or paint product. These products, which are available at most plant nurseries, help to limit the possibility of infections and rapid water loss. If a branch is cut larger than 3/4 of an inch, the wound should be treated.
Before sealing the wounds, check the trunk, branches and any other areas that are visible. Carefully apply the paste or paint in a place where it is not visible from the ground. If the product is meant to be removed later, mark the area with a stake so that you remember where it is located.
Training as You Prune
Dwarf weeping cherry trees have a long lifespan, so proper and continuous training is important. This will help to maintain the desired form of the tree, as well as keep it thriving. As you complete each section of pruning, wire the remaining branches into place and use stakes or props to keep the branches in position while they reset.
To limit root damage, hire a certified arborist to attend to large pruning projects. They will be able to safely cut back limbs while offering advice on how to maintain the tree.
Frequent Maintenance
Frequent maintenance of your dwarf weeping cherry tree is key for keeping its structure and growth under control. Check it regularly to assess the health of the tree and ensure ongoing safety. Pruning more often will prevent numerous problems within the tree and the risk of it becoming unattractive due to lack of maintenance.
The best time of year to prune a dwarf cherry is during the late winter, as this encourages growth and prevents the tree from becoming leggy.
Tools for Pruning
Using quality tools when pruning a dwarf weeping cherry tree is essential. Have a good pair of bypass shears on hand for small trimming jobs, and use a lopping shear or a pruning saw for larger branches. Sanitation is highly important to prevent any infections that may occur, so sterilise tools regularly with a solution of one part bleach to nine parts water.
Investing in a pole pruner is a practical solution for cutting high branches. A pole pruner is designed with a tensioner and saw attachment at the top of a long pole. With a pole pruner, you can safely and effectively reach higher branches of the tree.
Professional Assistance
For inexperienced tree owners, professional assistance can help you to effectively trim a dwarf weeping cherry tree. When selecting an arborist, it is important to look for a certified professional who carries the proper qualifications and has experience pruning dwarf cherry trees.
A certified arborist can provide advice on how to trim your cherry tree properly, and may be able to do the work for you if it is considered to be a large job. This could save you the trouble and the risks associated with attempting to trim the tree on your own.
