Don't water/protect from rain for a week and a half; when the top soil is dry, stick you finger in the soil - it should be a bit moist 2-3 inches deep, but not damp. The trunk and branches will feel noticeably 'rubbery'. When you've achieved these conditions its time to go!
soak raffia for 20-40 min until translucent. wrap tightly, weaving the raffia on it self as you go. Don't skimp on the raffia, this is what will keep the sap wood from bursting out the back of your bends, remember wrap tightly. Use aluminum wire, add the gauge( if using more than one wire) so that the sum of the wires you use is about 1/3 to 1/2 the trunk's diameter. The aluminum wire is more support that holding power. wire the section of trunk you wish to bend.
over wrap your work with rubber/electrical tape. now add copper wire if you have it.
you're now ready to bend.
as you add bends, keep your ear close to the trunk. ease the bend slowly, really slowly. you'll hear cracking if you going to far, but you really have to listen for it. add a bend, guy wire to hold, have a beer, work the bend a little further; repeat until you've got it where you need it. Large bends on thicker trunks could take well over an hour...
IF you hear cracking, you're done. slightly back the pressure off and let it heal til next year.
Judging from the picture, this doesn't look like the strongest tree. and the bending needs to be done close to the base...so the place your going to damage is the vein for the whole tree; so don't push it too crazy. I wouldn't wire or bend more than the bottom 12", the braches look small enough to add wire next year.
