Thank you so much for the replies. I knew these poor plants were in desperate need of some pruning and some light. They obviously want very much to live so I will do what I can to help them thrive. So it is really as simple as cutting the stem in to 6-7 in pieces and putting them in the same pot? I read somewhere that I should wrap them in a plastic sheet until they root. Also, I wondered if I needed to stake the one that has fallen and is growing horizontally. I can do this now, or should I wait until March or April.
