Have had great success with sedum, they are hardy, but last year and now again this year I have a problem. Just as they are thriving, they start flopping over and the stem gets a blackish yellow color, very soft. I see no evidence of rodents or insects but it is killing me. Any suggestions?

BFVISION,
What kind of dirt you growing them in???
And sun, and watering practices?????????

I am growing them in top soil that is covered with mulch. They only receive their water naturally for the most part and we have had a mild spring (not like last year). It is strange because one will fall in the midst of the other 5 in one bed, and the same will happen in the other bed. :(I`m thinking some kind of worm or borer. What do you think?

I think You Will find the problem here:
