hello! i have the same problem... I have a corn plant and it looks miserable, but I am hopeful that I can still revive it… As you can imagine we have to canes, a taller one which have few leaves and a smaller one that has none… The taller one has leaves/ shoots near the end of cane from the previous cutting, and another shoot located halfway of its length. I am planning to split the taller plant into 2, just above the leaves in the middle, so as to make two new separate plants. But I am scared that instead of reviving the plant, I might totally destroy it. Is my idea possible? Thanks for your time reading my post and hope to hear from you. here are some photos of my corn plant please help me to revive it.. thanks i'm thinking if i can split the bigger one into two just above the leave/shoots on the middle... smaller cane has no leaves at all...
I had a Dracaena that had gotten too tall for the room it was in; so, after a failed air layering attempt, I cut the growing top off about a foot below the bottom leaves and stuck it into a pot with fresh soil. After a month or two it recovered nicely and started to grow again. From that experience, I'd say that you should have a pretty good chance of success if you split the plant into two.
You may want to consider using a rooting hormone before potting up the cutting and applying wax to the top of the remaining stem to prevent desiccation.
Your plant looks a little sunburnt. They should be just a little darker green, especially at the edges. Perhaps consider waiting to chop it until after it has a few healthy leaves, then follow the good advice above for rooting. :)
