I always move plants at the end of dormancy (about March). Dig your shovel one shovel blade length straight down about 2 feet from the stem. Go completely around the plant. Now back up and dig at a 45 degree angle from about a foot farther away so you intersect the bottom of your shovel cut. Remove these triangles of dirt as you work around the plant. Now continue at an angle cutting under the plant and working around the plant until your cuts meet directly under the stem of the plant. I put on heavy plastic and drag the plant to the new hole cut to fit. Plant and saturate with B-1 and/or Superthrive and water to reduce transplant shock and encourage new root growth. Give one more B-1 treatment in a week and then go to your regular routine. I would keep my palm north of the plumeria so the sun is not blocked for your plumie. Hope this helps. Bill
