Yes, you can replant (transplant) aspen trees, and successful transplanting relies heavily on proper techniques, particularly concerning the size of the tree and the root ball.
Understanding Aspen Transplanting Success
Transplanting aspen trees is possible, and focusing on the health and size of the tree selected for replanting significantly increases the chances of survival. Younger, healthier trees generally adapt better to a new location.
According to expert recommendations, aspens 5-7 feet are often the healthiest trees for transplanting. This size range seems to offer a good balance between established root structure and adaptability.
Key Factors for Successful Replanting
When preparing to replant an aspen, the size and care taken during the digging process are critical. The goal is to preserve as much of the root system as possible within a manageable root ball.
Here are the essential steps based on best practices:
- Select the Right Tree Size: As mentioned, trees between 5 and 7 feet in height are typically the most vigorous and easiest to transplant successfully.
- Proper Root Ball Dimensions:
- Width: You need to dig a root ball that is 6 inches in diameter plus 3-4 inches for every inch in diameter of the trunk. This calculation ensures enough feeder roots are included.
- Depth: The root ball must be dug to a sufficient depth to capture the main root system. Dig at least 15 inches deep for any size tree being transplanted.
- Careful Extraction and Handling: Once the root ball is defined by digging, carefully work around it to free the tree. Protect the root ball from drying out before and during transport to the new location.
- Prepare the New Site: Dig a hole at the new location that is twice as wide as the root ball but only as deep as the root ball. This allows roots to spread easily outwards into loosened soil while ensuring the tree isn't planted too deep.
- Planting and Watering: Place the tree in the hole, ensuring the top of the root ball is level with the surrounding soil surface. Backfill the hole gently, water thoroughly to settle the soil and eliminate air pockets, and continue regular watering, especially during the establishment phase.
Root Ball Size Guidelines
To illustrate the root ball calculation provided, here's a simple breakdown:
| Trunk Diameter | Base Root Ball Diameter | Additional Width per Inch | Total Root Ball Diameter (Example using 3 inches/inch) |
|---|---|---|---|
| 1 inch | 6 inches | 3 inches | 6 + (1 * 3) = 9 inches |
| 2 inches | 6 inches | 3 inches | 6 + (2 * 3) = 12 inches |
| 3 inches | 6 inches | 3 inches | 6 + (3 * 3) = 15 inches |
Remember: The minimum depth for any tree is 15 inches.
By following these guidelines, particularly focusing on tree size and proper root ball dimensions during excavation, you can effectively replant aspen trees.
