I will cut the stem where I have made the long black mark on it..........was hard to do with a skinny plant tag pen. LOL Then I will lay it lenghwise in one of those long planters. Put the medium about halfway up on the stem. I tried to mark one of the "nubbies" where a new plant will grow..............*eventually*.......... No matter if there are nubbies under the soil or above; they seem to grow equally well for me. NOW is it clear what I do? Oh, and I will just stick the parent plant back in some soil and it will keep growing.
