Pruning is an essential practice for maintaining the health and aesthetics of trees. Regarding large trees, the importance of proper pruning cannot be overstated. However, pruning large trees requires careful planning, the right tools, and adherence to safety guidelines. In this article, I will share expert tips on how to prune large trees, ensuring both safety and efficiency.

Why is pruning important for large trees?

Pruning plays a crucial role in large trees’ overall health and longevity. Removing dead or diseased branches helps prevent the spread of decay and pests. Pruning also improves the tree’s structure, promoting better airflow and reducing the risk of branch failure during storms. Additionally, it enhances the tree’s appearance, allowing it to thrive in its surroundings. Pruning large trees is essential for the tree’s well-being and the safety of people and property in its vicinity.

When and how often should you prune large trees?

Knowing when to prune large trees is crucial to ensure optimal results. The ideal time for pruning depends on the tree species and its growth patterns. It is generally best to prune deciduous trees during their dormant season, typically in late winter or early spring. Pruning during this time minimises the impact on the tree’s growth and reduces the risk of disease transmission. However, certain trees, such as oak and elm, should be pruned during summer to prevent spreading diseases like oak wilt.

The frequency of pruning varies depending on the tree’s age, health, and desired outcome. Young trees require more frequent pruning to establish a robust framework, while older trees may only need occasional maintenance pruning. It is essential to assess the tree’s condition and consult an arborist to determine the appropriate pruning schedule for your large trees.

Tools and equipment needed for pruning large trees

Pruning large trees requires specialised tools and equipment to ensure safety and efficiency. Here are some essential tools you will need:

  • Pruning shears: Also known as hand pruners, these are used for cutting small branches and twigs. Choose a pair with a bypass-cutting action for clean cuts and minimal damage to the tree.
  • Loppers: Loppers have long handles and are designed to cut thicker branches. Look for loppers with sharp blades and a compound action mechanism for increased cutting power.
  • Pole pruners: Pole pruners come in handy for branches that are out of reach. They consist of a pruning saw attached to a long pole, allowing you to safely trim higher branches from the ground.
  • Chainsaw: A chainsaw is indispensable when dealing with larger branches or tree removal. Use a chainsaw with the appropriate safety features and follow all safety guidelines.
  • Safety equipment: Always prioritise safety when pruning large trees. Wear a hard hat, safety glasses, ear protection, gloves, and sturdy footwear. Consider using a safety harness or climbing equipment when working at heights. 

Safety precautions when pruning large trees

Pruning large trees can be hazardous if proper safety precautions are not taken. It is essential to prioritise safety to avoid accidents and injuries. Here are some crucial safety guidelines to follow:

  • Assess the tree and surroundings: Before starting any pruning work, thoroughly inspect the tree and its surroundings. Look for any signs of hazards, such as dead branches, power lines, or unstable ground. Ensure that the area is clear and safe for work.
  • Use proper ladder techniques: When using a ladder for pruning, make sure it is stable and positioned on level ground. Always maintain three points of contact with the ladder, and never overreach while pruning.
  • Follow correct cutting techniques: When making cuts, follow proper techniques to avoid injury. Cut outside the branch collar, avoiding leaving stubs or cutting too close. Use a three-cut method for larger branches to prevent tearing the bark.
  • Beware of power lines: Exercise extreme caution if power lines are near the tree. Never prune branches in contact with power lines or within their proximity. Contact a professional tree service or utility company to handle such situations.
  • Work with a partner: Having a partner during pruning can provide extra safety. They can assist in stabilising ladders, handing tools, and being available in emergencies.

Step-by-step guide to pruning large trees

Pruning large trees requires a systematic approach to ensure effective results. Here is a step-by-step guide to help you navigate the pruning process:

  • Assess the tree: Begin by assessing the overall health and structure of the tree. Identify any dead, diseased, or crossing branches that must be pruned.
  • Plan the pruning cuts: Determine the ones needed to achieve your desired outcome. Make sure to follow proper pruning techniques, such as cutting outside the branch collar.
  • Start with dead branches: Begin by removing any dead branches. Deadwood can attract pests and diseases, so it is crucial to remove them first.
  • Address diseased branches: Identify and remove branches showing signs of disease or infection. Prune at least 6 inches below the affected area to ensure complete removal.
  • Remove crossing branches: Crossing branches can rub against each other, causing damage and disease. Remove one of the crossing branches to maintain a healthy structure.
  • Thin-out overcrowded branches: If the tree has dense foliage, selectively remove some branches to allow better airflow and sunlight penetration. This helps prevent diseases and promotes overall tree health.
  • Maintain the tree’s natural shape: When pruning, aim to maintain the tree’s natural shape and form. Avoid excessive pruning that can stress the tree or compromise its stability.
  • Clean pruning tools: After completing the pruning work, clean and sanitise your tools to prevent the spread of diseases. Remove any debris from the tree’s vicinity to maintain cleanliness.

Common mistakes to avoid when pruning large trees

Pruning large trees requires skill and knowledge to avoid common mistakes that can harm the tree or compromise its safety. Here are some mistakes to avoid:

  • Topping: Topping, the indiscriminate removal of large branches or the tree’s crown, is a harmful practice that should be avoided. It weakens the tree, promotes rapid regrowth, and ruins its natural form.
  • Over pruning: Excessive pruning can stress the tree and disrupt its ability to produce energy through photosynthesis. Avoid removing more than 25% of the tree’s foliage in a single season.
  • Improper pruning cuts: Incorrect pruning cuts, such as leaving stubs or cutting too close to the trunk, can lead to decay, pests, and disease. Always follow proper cutting techniques.
  • Pruning at the wrong time: Pruning at the wrong time can negatively affect the tree. Understand the tree species and its growth patterns to determine the appropriate pruning timing.
  • Ignoring safety precautions: Neglecting safety precautions can result in accidents and injuries. Always prioritise safety and follow the necessary guidelines when pruning large trees.

Hiring a professional for pruning large trees

Pruning large trees can be challenging and potentially dangerous, especially if you lack the necessary experience and equipment. In such cases, hiring a professional arborist to handle the job is always wise. Here are some reasons to consider hiring a professional for pruning large trees:
