I have a corn plant I received as part of a plant dish from my husband's funeral. I replanted all the plants and they all have done very well, not like my usual houseplants. One dish contained a corn plant. I do not know the official name, it looks like a corn stalk, but no ears of corn, at least so far. This plant is now over 5 feet tall. I have repotted it several times but it is getting way too big. How can I get this plant to stop growing or how can I safely shorten it? It has a lot of sentimental value to me. Thank you Jenne
