Question
I have a Ponderosa pine growing under a large bay window. It is right against the foundational slab and very healthy. I am in western New Mexico at approx. 6,500 ft in elevation.Todays date is July 15,2009. What is the best way/time to move the future 'giant' without stressing it out and losing a gorgeous little tree.  Thank you for any advice.....Kirk

Answer
Not the time to move the tree now wait. Evergreens should be moved earlier in the fall than deciduous plants so they have time to form new roots. They need at least 6 weeks before the ground freezes. In the spring, Evergreens can be planted up to 4 weeks after deciduous trees have opened their leaves, providing that the newly planted trees receive adequate water.

Digging the root ball:

When you want to dig up a tree or shrub for transplanting, retain as much of the root system as possible. Deciduous trees that are only 3-4 years old may be moved with their roots bare.

All ages of evergreens, can be successfully moved only if a ball of soil is left around the roots. The exposed roots should be protected with moist burlap or newspaper or with polyethylene sheeting. Every effort should be made to reduce root exposure to wind and sun, keeping the ball as moist as possible. It's best to prepare the hole before digging up the tree you wish to move.

Size of the root ball and size of the hole:

For deciduous trees and shrubs the soil ball should be:

Width = 9-12 in. in diameter/every 1 in. of tree diameter
Depth = 6 in./every 1 in. of tree diameter

For example: A tree trunk 2 inches wide would need a soil ball of 18-24 inches wide and 12 inches deep.

Dig the new hole twice the size of the root ball and as deep and fill with good top soil or potting soil. Mulch around the tree with not more than 3 inches deep of organic mulch (pine straw is good)not piled up on the trunk. This will help hold moisture around the roots. o
