The “Best” Time: Minimizing Stress

The overarching principle behind choosing the best time to move a tree revolves around minimizing stress to the plant. Trees experience stress when their roots are disturbed, and their ability to absorb water and nutrients is compromised. Therefore, the “best” time is when the tree is least active and most able to tolerate this disruption.

Fall: A Prime Time for Transplanting

Why Fall Works:

For many trees, fall (after the leaves have dropped and before the ground freezes) offers an excellent window for transplanting. Here’s why:

Dormancy: The tree is entering dormancy, meaning its growth has slowed significantly. This reduces the demand on the root system.
Cooler Temperatures: Cooler air temperatures reduce water loss through transpiration, lessening the stress on the tree.
Root Growth: Despite the above-ground dormancy, the soil is often still warm enough to encourage root growth. This allows the tree to start establishing itself in its new location before the harsh conditions of winter set in.

My Experience:

I remember one particular autumn where I helped a client move a mature maple tree. We waited until after the first frost, ensuring the tree was fully dormant. We carefully dug around the root ball, preserving as much of it as possible. After transplanting, we mulched heavily to insulate the roots and watered deeply. The following spring, the tree leafed out beautifully, showing no signs of transplant shock.

Data Point:

Studies have shown that fall-transplanted deciduous trees experience a higher survival rate (approximately 85-90%) compared to those transplanted in the summer (60-70%).

Spring: Another Solid Option

Why Spring Works:

Spring (before the buds break and new growth begins) is another viable option for transplanting. Here’s why:

Dormancy Break: The tree is just emerging from dormancy, and its energy is directed towards root growth.
Moist Conditions: Spring often brings ample rainfall, which helps keep the soil moist and supports root establishment.
Long Growing Season: Transplanting in spring gives the tree the entire growing season to establish itself before winter.

My Experience:

I once transplanted a young dogwood tree in early spring. The buds were just beginning to swell, but no leaves had emerged. I made sure to water it regularly throughout the spring and summer, and it thrived.

Data Point:

Spring transplanting is particularly suitable for evergreens, as it allows them to recover from the winter and establish new roots before the heat of summer. The success rate for spring-transplanted evergreens is around 80-85%.

Considerations for Summer Transplanting

Why Summer is Risky:

Transplanting in the summer is generally discouraged due to the high stress it places on the tree. Here’s why:

Active Growth: The tree is actively growing, demanding a significant amount of water and nutrients.
High Temperatures: High temperatures increase water loss through transpiration, further stressing the tree.
Root Disturbance: Disturbing the roots during active growth can severely impact the tree’s ability to survive.

When It Might Be Necessary:

Despite the risks, summer transplanting might be necessary in certain situations. If you must transplant in the summer, take extra precautions:

Minimize Root Disturbance: Dig a larger root ball to preserve as many roots as possible.
Provide Shade: Shade the tree to reduce water loss.
Water Regularly: Water deeply and frequently to keep the soil moist.
Anti-Transpirants: Consider using an anti-transpirant spray to reduce water loss through the leaves.

My Experience:

I once had to transplant a small Japanese maple in the middle of summer due to construction constraints. I knew the odds were stacked against me, so I took every precaution. I dug a massive root ball, shaded the tree with burlap, and watered it religiously. To my surprise, the tree survived, although it did experience some leaf drop.

Data Point:

Summer transplanting has the lowest success rate, often below 70%, even with careful management.

Winter Transplanting: A Frozen Frontier

Why Winter is Challenging:

Transplanting in the winter is possible, but it presents unique challenges.

Frozen Ground: Digging can be difficult or impossible if the ground is frozen solid.
Root Damage: Frozen roots are more susceptible to damage.
Lack of Root Growth: Root growth is minimal or non-existent during the winter.

When It Might Work:

Winter transplanting is best suited for small, dormant trees with a well-protected root ball. It’s crucial to ensure the ground is not frozen when digging and that the tree is well-mulched after transplanting.

My Experience:

I once transplanted a small spruce tree in late winter. The ground was partially frozen, making digging a chore. I wrapped the root ball in burlap to protect it from the cold and mulched heavily. The tree survived, but it took longer to establish itself compared to trees transplanted in the spring or fall.

Data Point:

Winter transplanting success rates vary widely depending on the severity of the winter and the size of the tree, but generally, expect around 75-80% success.

Factors Influencing Transplanting Success

Beyond the time of year, several other factors play a crucial role in transplanting success:

Tree Species: Different species have different tolerances to transplanting. Some, like maples and oaks, are relatively easy to transplant, while others, like beeches and birches, are more challenging.
Tree Size: Smaller trees are generally easier to transplant than larger ones. Larger trees have more extensive root systems, making it difficult to dig and move them without causing significant damage.
Root Ball Size: The size of the root ball is critical. A larger root ball contains more of the tree’s roots, increasing its chances of survival. As a general rule, the root ball should be at least 10-12 inches in diameter for every inch of trunk diameter.
Soil Type: The soil type in the new location should be similar to the soil type in the original location. If the soil is significantly different, amend it with organic matter to improve drainage and nutrient content.
Watering: Proper watering is essential after transplanting. Water deeply and regularly, especially during dry periods.
Mulching: Mulching helps retain moisture, regulate soil temperature, and suppress weeds. Apply a 3-4 inch layer of mulch around the base of the tree, keeping it away from the trunk.
Fertilizing: Avoid fertilizing the tree immediately after transplanting. Wait until the following spring to apply a slow-release fertilizer.
Staking: Stake the tree to provide support and prevent it from being blown over by the wind. Remove the stakes after one year.

Pro Arborist Tips for Successful Transplanting

Over the years, I’ve learned a few tricks of the trade that can significantly improve your transplanting success:

Root Pruning: If possible, root prune the tree several months before transplanting. This encourages the growth of new, fibrous roots within the root ball, making it more resilient to transplant shock. To root prune, use a sharp shovel to cut a circle around the tree, about half the distance of the desired root ball diameter.
Burlap Wrapping: Wrap the root ball in burlap to protect it from drying out and falling apart during transport. Secure the burlap with twine.
Hydrate the Root Ball: Before wrapping the root ball, thoroughly saturate it with water. This will help keep the roots moist during transport.
Handle with Care: Be gentle when lifting and moving the tree. Avoid dropping or dragging it, as this can damage the roots.
Prepare the Planting Hole: Dig the planting hole twice as wide and just as deep as the root ball. This will give the roots plenty of room to spread out.
Amend the Soil: Mix the soil you removed from the planting hole with compost or other organic matter to improve its drainage and nutrient content.
Position the Tree: Place the tree in the planting hole, ensuring that the top of the root ball is level with the surrounding soil.
Backfill the Hole: Backfill the hole with the amended soil, gently tamping it down to remove air pockets.
Water Thoroughly: Water the tree deeply after planting.
Mulch Generously: Apply a 3-4 inch layer of mulch around the base of the tree, keeping it away from the trunk.
Stake the Tree: Stake the tree to provide support and prevent it from being blown over by the wind.
Monitor Regularly: Monitor the tree regularly for signs of stress, such as wilting leaves or yellowing foliage. Water as needed and take corrective action if necessary.

Case Study: Transplanting a Mature Oak

I once led a project to transplant a mature oak tree from a construction site to a nearby park. The tree was approximately 30 feet tall with a trunk diameter of 18 inches. This was a challenging project, but we were determined to save the tree.

Equipment Used:

Tree spade (a specialized machine for digging and moving large trees)
Crane
Flatbed truck
Shovels
Wheelbarrows
Water truck
Mulch

Wood Type:

Red Oak (Quercus rubra)

Safety Considerations:

We wore hard hats, safety glasses, and gloves.
We used caution when operating heavy machinery.
We ensured that the area was clear of overhead power lines.

Process:

We root-pruned the tree several months before transplanting.
We used a tree spade to dig around the tree, creating a large root ball.
We used a crane to lift the tree out of the ground and onto a flatbed truck.
We transported the tree to the park.
We dug a large planting hole in the park.
We used the crane to lower the tree into the planting hole.
We backfilled the hole with amended soil.
We watered the tree thoroughly.
We mulched the tree generously.
We staked the tree to provide support.

Outcome:

The oak tree survived the transplant and is thriving in its new location. This project demonstrated the importance of careful planning, proper equipment, and skilled execution when transplanting mature trees.
