cutting back overgrown dendrobium?
 

Can i replant long stalks after i cut them off? I will also splitting the roots to make at least two plants. Any advice appreciated?

Pictures would help and which Dendrobium.

are the canes leafless...if so you can divide the cut offs as long as each cutting has two nodes...it can take up to a year for the whole process...lay the cuttings in a tray with moist sphagnum moss...place each try in a clear plastic bag or heated propagator..new growth will appear in 3 or 4 monthes...wait till you have good roots....at least a few inches worth...then cut from stem and plant

Here is the photo, the branches that has no leaves had leaves up until this winter

I dont see a reason why you would want to divide it.
If you want to propagate it, you can remove a cane and use the above technique.

Takes up alot of room over two feet of room as you can see by the tiles on the floor, pot becomes off balance and tips over, roots bound

Dendrobiums like to be root bond... can you place whole pot in larger container
and fill with rocks so is more stable?

I like the basket idea and i happen to have one to be repaired . I still like to cut the long stem that don't have leaves.
