i have a beautiful christmas cactus(3-4years old)given to me from my father... and it bloomed beautifully this past christmas for me for 1st time howver i went out of town not expecting a freeze (Texas) and the temp dropped below freezing for several nights. when i returned it looked like limp asparagus with fuschia tips drooping down sides of my pot :( what do i do to save it? my father had grown it from branches of hisown cactus before he died last year. needless to say i dont want it to die. Can i save it?
