Tree trimming refers to the selective removal of specific branches or parts of a tree to improve its health, structure, and appearance. By trimming dead, diseased, or overgrown branches, you help the tree grow properly, reduce the risk of decay, and enhance its overall look. Trimming also promotes better airflow, light exposure, and safety by preventing branches from falling or interfering with power lines and structures.

The best tree trimming technique depends on the tree's condition, but generally:

• Start by removing dead, diseased, or damaged branches: This prevents the spread of disease and improves the tree’s health.
• Prune for structure: Remove weak or crossing branches to promote a balanced shape and strong framework.
• Trim for sunlight and airflow: Thinning out dense areas of the tree allows more sunlight and air to pass through, promoting healthy growth and reducing the chance of fungal growth.
• Make clean cuts: Always trim branches just outside the branch collar (the swollen area where the branch connects to the trunk) to allow proper healing. Use sharp tools to avoid tearing the bark.
• Don't over-trim: Avoid removing more than 25% of the tree’s foliage at once, as this can stress the tree and slow its growth.

• Trimming: Focuses on enhancing the health and aesthetics of a tree. It involves selectively removing smaller branches to shape the tree, improve its structure, and encourage healthy growth.
• Cutting: Usually refers to removing larger portions of a tree, like felling large branches or the entire tree itself. Cutting is more aggressive and often necessary when dealing with diseased trees, hazardous limbs, or complete tree removal.

For very tall trees, safety is the top priority:

• Use the right tools: Long-handled pruners or a pole saw can help you reach high branches without needing to climb the tree.
• Start from the top: Begin trimming from the uppermost branches and work your way down. Remove smaller, weak branches before addressing larger ones.
• Cut in stages: For thicker branches, make a series of smaller cuts rather than one large cut to avoid damaging the tree.
• Seek professional help: For trees that are extremely tall or difficult to reach, it’s best to hire a professional tree care service to handle the job safely.

The best time to trim most trees is during late winter or early spring (February to April), just before the growing season begins. During this period:

• Trees are dormant, meaning they aren't actively growing, which reduces stress on the tree and minimizes the risk of disease.
• It’s easier to see the tree’s structure without leaves, which helps guide your trimming.
• Pruning just before the tree enters its growth phase allows wounds to heal quickly as the tree begins to grow in the spring.

For flowering trees, it’s important to trim them right after they bloom to avoid cutting off next season’s flowers.
