Hello!

First, the name. This is not the corn plant (Dracaena massangeana, aka Mass cane), what you have is Dracaena deremensis 'Janet Craig', JC cane or Janet Craig for short.

This looks like flouride damage as a result of being too dry (you can tell simply looking at the leaves, how they are all wilted looking that its been going way too dry!) As the soil dries down, salts in the soil-water become more concentrated, and the plant takes up that concentrated salt-water. Once in the plant, the salts create this yellowing that you see. The yellow itself will never go away but theres a few things that will help:

1. That looks like its in strong light: WATER!!!! JC canes can be relatively heavy drinkers in high light. Do NOT let them dry down too much. Let it get down to the consistency of a wrung out sponge, then give it a solid half gallon...this should last about a week or so in that light.

2. Buy horitcultural lime from lowes/home depot/local gardens center and apply it to the soil, making sure to follow the label directions. Raising the pH of the soil with lime will help lock out the flouride so the plant won't take it up.

3. Since you have this at home, you have the luxury of leaching. Once a month or so, take it to the bathroom or outside and run lots of pure water through the pot. This will wash out any salts that have accumulated in the soil, preventing this damage.

4. When was the last time you repotted your plant? Fresh soil will definitely benefit the plant if it hasn't been repotted in a long time. Nows a good time of year to do it.

5. Consider cutting down the stalks to within a few inches of the soil line and letting it branch out. The yellow will not go away, pruning them down will give you new, lush, green growth and reinvigorate the plant. A 2nd chance, if you will.

6. Barring that, remove all the old dried reminants of cut leaves. Pests can hide in there and breed, unbeknownst to you!

7. In the meantime, consider cutting off as much of the yellow as you can. If its concentrated at the end of the leaf, you can simply cut the leaf below the yellow, making sure to cut it into the shape of a leaf instead of simply cutting right across. It will look more natural this way.

Good luck with your plant! I have a lot of suggestions here, but really this is a common problem that can be prevented and corrected with just a few simple steps! Most important are don't let it dry down, add lime, and leach the pot, in that order. Just doing these will improve the whole issue 100%!

I have a dracaenia which languished until I moved it to the humidity of a master bathroom with a full facing southern exposure. The extra light, moisture and soil dampness rid it of the dead ends you have on your plant. I also flush the pot yearly. Once all the old dead leaves fell off only lush green ones remained.

good luck with your special plant!
