Question: I have a corn plant dracaena that is too tall. How do I cut it back so I can keep it in my house? Can I use the top to start new plants?
Answer: Most corn plants were started from dormant canes that were potted, then encouraged to send out shoots with leaves. Usually you can cut the plant back fairly close to the old cane stump and it will regrow, often with two branches where you had one before. Frankly, it’s difficult to describe exactly how that cut should be made without seeing the specific plant in question. As for starting new plants, your best bet would be to air layer the top before you cut it. If you happened to have a greenhouse with a mist propagation bed, you could probably root the severed top, but otherwise it will be quite difficult.
