They are not real picky about soil so long as it is well drained. Pretty much treat them like any succulent and let them dry out between waterings. Some people fertilize theirs but I have never added anything but water to mine and they do great!
Good drainage is truly the key. When they flower they are gorgeous, however, dead the head will be, new little ones will pop out under the mother hen, thus the name. These plants originated in Europe. Norma
