I have a very nice mixed pot with Autumn Joy Stonecrop (Sedum) and some unknown red beachy looking grass (possibly red fountain grass). It's all been doing really well on my "full sun" porch but we've had heavy rains 4 different days of this past week while I was out of town. It appeared to be in perfect condition until my dog brushed up against the Sedum and I realized, that a large stem of this usually sturdy plant knocked over... Could it have uprooted? No- the bottom of it is soaked and some of the leaves have turned to mush. I inspected the rest, which seems to be fine, but this strand, like most of it has at large clump of buds on top that should bloom over the next few weeks.
Like other sedums, am I able to clip off the bottom that's basically rotting, give it time to callus and transplant the stems elsewhere? I've done this with Sedum refexum and coral carpet, but they weren't upright sedums, so I am unsure... And everything I've read about transplanting the Autumn Joy talks about gently moving the entire root structure. Does this mean I have lost this entire bit, it is there still hope? If I cannot clip it, is there something I can do? Is it possible to submerge the bottom bit that's damaged with sand or something else to soak up the moisture?
If it will help, I will edit this post with pictures in the morning, when I have proper light.
