Step by Step: What You Need to Know Before Moving a Large Tree How to Move a Large Tree 

One of the first steps in determining how to move a large tree is understanding tree diameter. Diameter helps determine the required root ball size and the right spade size needed for a successful move. 

Tree Diameter Matters More Than Height 

For transplanting, trunk diameter at approximately 6 inches above ground level is the most reliable measurement. This dictates how large the root system must be to keep the tree healthy during the move. 

Spade Size and Root Ball Requirements 

Larger trees need larger root balls, and therefore larger spades. Professional equipment can handle trees with substantial trunk diameters as long as the correct spade size is used to protect the roots.  

Keeping as much of the root system intact as possible is the foundation of a successful transplant, especially for mature trees with established root structures. 

Step 2: Evaluate Soil Conditions 

Soil conditions play a major role in whether a mature tree can be successfully relocated. Soil must be firm enough to hold the root ball together but not so compacted that the spade cannot penetrate smoothly. 

Ideal Soil Conditions for Moving 

Generally, the best conditions include: 

• Moist but not muddy soil 

• Soil that is stable enough to hold together during lifting 

• Minimal large rocks or debris 

• Good drainage 

Why Soil Conditions Matter 

Proper soil structure ensures the root ball remains intact during extraction, transport, and replanting. This reduces stress and increases long term survival. 

Professionals will typically inspect the soil ahead of time to confirm it's suitable for a successful lift. 

Step 3: Check Access Requirements for Equipment 

Before moving a large tree, proper access is essential. Mature tree moving equipment requires space to maneuver safely. 

Access Requirements Include: 

• Wide enough path for the tree spade truck 

• Stable, level ground for positioning 

• Space for turning, reversing, and aligning the spade 

• Height clearance from branches, buildings, or utilities 

Why Access Matters 

Even a perfectly healthy tree cannot be moved if equipment cannot reach it safely. Access requirements ensure the move is done efficiently and without damaging surrounding structures. 

Professional crews will normally walk the site to confirm the equipment can reach both the removal and planting locations. 

Step 4: Choose the Right Timing and Seasons for Moving a Large Tree 

Timing matters. While mature trees can be moved throughout much of the year, certain seasons offer the highest success rates. 

Best Seasons for Moving Large Trees 

Generally, moves are most successful during: 

• Early spring before leaf out 

• Fall after the tree begins entering dormancy 

These times reduce stress because the tree is temporarily at rest. 

Seasonal Considerations 

Extreme heat, frozen ground, or drought can create challenges. The goal is to move the tree when it can focus energy on root recovery rather than canopy growth. 

Colorado’s climate makes spring and fall the ideal windows, but professionals can help determine the best timing based on tree species and site conditions. 

Step 5: Complete a Utility Check Before You Dig 

Before any digging begins, a utility check is essential for safety and compliance. 

Why Utility Checks Matter 

Tree spades reach significant depths, which means underground utilities must be identified and cleared: 

• Gas lines 

• Water lines 

• Communication lines 

• Irrigation systems 

• Electrical lines 

Professional Guidance 

A utility check ensures safe digging and avoids damaging critical infrastructure. It also determines if the tree can be relocated without risk. 

Skipping this step is never an option proper safety and compliance protect both people and property. 

Step 6: Prepare the New Planting Site 

Preparing the new planting location is just as important as preparing the tree itself. The site needs to be properly shaped and ready for immediate placement. 

Site Prep Includes: 

• Ensuring adequate access for the tree spade 

• Digging a matching hole using the same spade size 

• Checking the soil for drainage 

• Ensuring correct depth and positioning 

Matching the Root Ball Shape 

Using the same spade to prepare the new hole helps ensure a snug, secure fit. This reduces air pockets and promotes faster root re establishment. 

Preparing the site ahead of time means the tree can be lifted and replanted without delay, reducing stress. 

Step 7: The Move How the Tree Is Lifted and Repositioned 

At this stage, the tree spade positions around the tree, secures the root ball, and lifts the tree in one controlled motion. 

How Professional Equipment Works 

Large tree spades: 

• Create a smooth, consistent root ball 

• Reduce shock to the tree 

• Keep the root system stable during transport 

• Allow the tree to be moved quickly and safely 

Transporting the Tree 

The tree is transported in an upright position and placed directly into the prepared site. Speed and safety are the priorities to reduce stress on roots. 

With proper equipment and experienced operators, even large mature trees can be moved efficiently and with excellent survival rates. 

Step 8: Replanting and Backfilling 

Placing the tree correctly is crucial to its long term success. 

Proper Replanting Includes: 

• Ensuring the tree is straight and aligned 

• Backfilling with the original soil 

• Removing air gaps 

• Watering thoroughly 

Why Backfilling Matters 

Settling the soil around the root ball ensures stability and allows the root system to begin re establishing itself immediately. 

A secure root ball and proper soil contact give the tree the best possible restart in its new location. 

Step 9: After Care for Newly Moved Large Trees 

After care is a critical part of how to move a large tree successfully. Even with excellent equipment and a smooth move, the tree needs proper care as it adjusts. 

Key After Care Includes: 

• Deep, consistent watering 

• Monitoring soil moisture 

• Mulching to preserve moisture 

• Avoiding fertilizing for several months 

• Watching for stress signs in the canopy 

Why After Care Matters 

A newly moved tree needs time to rebuild fine root hairs and adjust to its new environment. Proper watering is the single most important factor in long term survival.
