MAGNOLIA grandiflora ‘Exmouth’ (Bull Bay Magnolia)

Before you begin, it's essential to identify the root zone or root ball of the tree. This is the area where the majority of the tree's feeder roots are located. It is typically estimated as 1 foot of root ball diameter for each inch of tree trunk diameter.

Root pruning should occur a few months before the actual move, ideally in the dormant season. This involves cutting a trench around the root zone to encourage the growth of new feeder roots, which will help the tree to establish itself in its new location.

Prior to digging, prune dead or excessive branches from the tree. This reduces the tree's overall mass, making it easier to handle, and decreases water loss post-transplant.

After determining the root ball's size, begin digging around it. Try to retain as much soil around the roots as possible. The depth should ideally get under the root system but be feasible for lifting.

Once you've dug around the periphery of the root ball, begin undercutting to sever the remaining roots beneath it.

With the root ball freed, carefully lift the tree out of the hole. For large trees, this will likely require machinery like a tree spade or crane. Always lift the tree by the root ball, not the trunk.

Once the tree is out of the ground, it's critical to protect the root ball to prevent damage. Wrap it in burlap and secure it with twine, wire or steel basket. This not only holds the root ball together but also helps retain moisture.

Prior to transportation, water the root ball thoroughly to ensure the roots stay moist.

Load the tree carefully onto a truck or trailer for transport. The tree should be securely positioned to avoid damage during transit. The tree should ideally be planted in its new location as soon as possible to minimize stress and increase its chance of survival.
