lately i've been having some trouble with my golden lloydiella/creeping jenny (i've seen a couple different kind of plants called creeping jenny). i got 7 stems in a bunch a couple weeks past, all healthy, with two large leaves at every node. they didn't seem to have any roots, so i just stuck them in the sand with a root tab underneath. they seemed ok for a while, but they kept sending out roots from the points where the leaves grew off the stem, like so:
but never growing roots at the base, where they were in the sand. now, as you see, there are little new stem growths sprouting very fast at each leaf node with small leaves, like they're their own little plantlets. the original stems and large leaves have begun to increasingly melt away underneath each plantlet, starting from the bottom up. so, how the heck am i supposed to plant this and what am i doing wrong? i haven't had much success with stem plants in general (i massacred a bunch of ludwigia repens this spring too, no idea why), i wonder if i'm missing something obvious about how to plant them.
i use flourish and excel once a week, as well as a couple of the api root tabs under the sand, though it's just plain petco sand itself. lighting is 26 watts over 4 gallons, so it should certainly be enough. the dwarf lily is fairly exploding next to it so i don't know what's different.
