Even though this is directed to Mark, when I pull my rooted plumeria from the perlite, there will not be many roots. Sometimes there will only be a couple that are an inch long. I guess if you left it in the perlite a good, long time, there would be lots of roots. I just see no need to do that. I use my regular plumeria mix when I pot these newly rooted plants. I always dig a 2-3" deep hole so that I can place those rooted stems without damage to the tender roots. I use a very well-draining mix, 1/2 (custom) potted soil, 1/4 orchid mix, and 1/4 coarse perlite. I stake these plants with cane, sometimes one, sometimes two, depending on the height of the plants.
