If you don't have any leaves on the bottom, I would definitely wait until spring to cut it back. I would experiment with cutting back only one stem when you do. Good luck and keep me posted.

I don't have any leaves at the bottom, so I'm afraid to cut it back. Perhaps in the Spring I'll cut the stems down and hope for the best. Good idea?

Thanks, again!

I believe you have some type of insect damage occurring. Look for the following things a sticky substance on the leaves can indicate aphid damage; a white or cottony substance can indicate scale damage;small moving insects seen with a magnifying glass indicates spider mite infestation.
All of these can be controlled with either a soapy water mixture or a houseplant insecticde from your local nursery & garden center.

You plant, also, looks as if it is under going a water or temperature issue. If this plant was previously outside and then brought in that could be the cause of some of the problems. Check to make sure that an air vent is not blowing directly on the plant. As for water, make sure that the plant is allowed to dry slightly before you water it.

Does the plant have any lower leaves? If so, I would trim the long thin stalks back to the lower green leaves. In a few weeks fertilze the plant and it should start to put on new growth.
Good luck and keep me posted.
