Gosh, there are several different types of bamboo plants. If it has grown that much you are doing SOMETHING right. You can grab a little bag of Miracle grow at a large grocery store like Albertsons. Wal Mart sells it too. There is a new type that holds moisture longer so if you plan to be away, it won't dry up as fast.
Is there new growth anywhere on this plant? Sometimes leaves will fall due to age or handling. You could take a very sharp knife (a razor is prefered, but I use knives) and cut it at a joint-stick it in water and let a new one root.

Water-it spans the spectrum like an air fern-no soil, no water, just humidity in the air...to a water lily. Same thing goes for sun-
Cacti to Closet Plant. Are you anywhere near a nursery? Most will tell you what is happening.
I have a schefelera I bought for $9.00 at a Houston flea market in '76. It has been through hell and back. I know you don't want to lose this plant. You could just drop in and ask. It could need a "shower". Spider mites can attack that type of leaf. You can control them by putting your plants in a shower or taking them outside and rinsing the UNDERSIDE of the leaf as well as the top.

If you knew the exact type (name) I could do a better search on Google. It has a TON of info on plants. You just need to que in the term "culture" as it refers to what it needs to grow.

edited-the bigger the plant, the more careful you have to be with the roots. It's their supplier for their food source and if the littlest ones get damaged, it can't get what it needs. You have a dilema...
