I would highly suggest that you first make sure that the plant is compatible to you new area first, then I would consult with your local garden center, I am pretty sure that they will tell you to dig around the plant with a very small trowell or something small as to not disturb the root system too much. Any plant transplanted will go into some kind of shock, so be as careful as possible. Use lots of water to keep the ground soft and the roots plyable, this way you won’t do too much damage to the supporting roots. The most important part of all of this is to get all of the “TAP” root. That is the main root. If you damage this to much you will lose the plant. So be gently and careful. When you get the plant free, take some of the soil that you have removed and put it in a 5 gal. bucket to bring it along with you for replanting. Wrap the roots in Newspaper and place in a plastic bag. Dampen the Paper so the roots don’t dry out. Keep the roots moist all the time. Make sure that the New Home for the plant is similar in location from which it came from. Make the HOLE 2 times the size of the ball (rootsystem) area. Wet down the hole makeing sure of NO standing water. If there is standing water, you will need to dig deeper and back fill the hole with good soil or choose another location. After all this then take about half of the dirt you brought from it’s previous home and spread it all around the hole. Then start back filling, starting with dirt from the previous home and alternate with the new home soil. Water it in well, this will get the air out and the soil back around the roots properly. Keep an eye on it, MIST the stem area daily, in the morning, NEVER in the evening hours. Use a light fertilizer about 2 weeks after planting to help new roots better establish. However, if you have access to “fish water” use that from day one. Pond water, fish water, both are excellent healthy fertilizers for happy plants.
Best of Luck to you and I hope that I have helped you! :D
