Do you think the lower parts will ever fill in? Been like this for a fewmonths,,also,,how do you do that,,thank you!!

The soil looks very wet - is it?
These plants naturally grow taller, and respond well to pinching or pruning. If you want shorter & fuller plant, that's what should be done.
You could cut off top of branches and just lay them on soil surface, they should grow roots.

Looks to me that pot is sitting inside of a cache pot, maybe water is there killing the roots?

Not the best photo,Looks wetter than it is,,could use better soil though, not the best draining.. Thanks miracal grow.....But going to make a better mix..the tops are the only new growth, all the rest shriveled n fell off..never stands in water though..I'll try the pinching, thanks Rina
