Tree Trimming Guide: Everything You Need to Know

Why Tree Trimming Matters

Professional tree trimming does more than just improve appearance. Regular pruning:

• Promotes tree health – Removes dead, diseased, or damaged branches before problems spread
• Improves safety – Eliminates weak branches that could fall and cause damage
• Enhances appearance – Maintains attractive shape and proportion
• Increases sunlight – Allows more light to reach your lawn and gardens
• Prevents damage – Keeps branches away from your home, roof, and power lines

Best Time to Trim Trees in Colorado

Timing matters when it comes to tree trimming. Here's what works best in our Colorado climate:

Late Winter to Early Spring (February - April)

This is the ideal time for most tree trimming because:

• Trees are dormant, reducing stress from pruning
• Without leaves, the branch structure is visible
• Wounds heal quickly as spring growth begins
• Disease transmission risk is lower

Summer Trimming

Summer trimming can be appropriate for:

• Removing dead or damaged branches (any time)
• Controlling rapid growth
• Addressing clearance issues
• Shaping flowering trees after blooming

When to Avoid Trimming

Generally avoid trimming in:

• Fall – Trees are preparing for dormancy and wounds heal slowly
• During extreme heat or drought – Additional stress can harm the tree
• When trees are flowering – Wait until after bloom for spring-flowering trees

Types of Tree Trimming

Crown Cleaning

Removes dead, dying, diseased, and broken branches. This is the most basic and essential type of tree trimming that benefits all trees.

Crown Thinning

Selectively removes branches to improve light penetration and air circulation while maintaining the tree's natural shape. This reduces wind resistance and disease risk.

Crown Raising

Removes lower branches to provide clearance for buildings, vehicles, pedestrians, or sight lines. Important for trees near walkways and driveways.

Crown Reduction

Reduces the overall size of the tree by removing branch ends. Used when a tree has outgrown its space or to reduce weight on heavy branches.

Structural Pruning

Particularly important for young trees, this training pruning establishes good branch structure and prevents future problems.

DIY vs. Professional Tree Trimming

What You Can Do Yourself

• Prune small branches (under 2 inches diameter)
• Remove dead twigs and small branches within reach
• Shape young shrubs and small trees

When to Call a Professional

• Large branches (over 2 inches diameter)
• Work requiring a ladder or climbing
• Branches near power lines
• Large trees of any kind
• Trees showing signs of disease
• Storm damage cleanup

What to Expect from Professional Service

When you hire a tree trimming professional, here's what should happen:

1. Assessment – They evaluate your tree's health, structure, and your goals
2. Recommendation – They explain what trimming is needed and why
3. Quote – You receive a clear price for the work
4. Professional pruning – They use proper techniques and equipment
5. Cleanup – All debris is removed from your property

How Often Should Trees Be Trimmed?

Frequency depends on tree type and situation:

• Most trees – Every 3-5 years for maintenance trimming
• Fast-growing trees – Every 2-3 years
• Trees near structures – More frequently as needed for clearance
• Fruit trees – Annually for optimal production
• Young trees – Training pruning every 2-3 years until established
