All the leaves have turned brown and shriveled except there is new growth at the very top center of the plant. Should I cut it back?
Trimming the damaged leaves is an option, pruning is another. If it was just frost and not temps in 20-25 degree range for more than an hour, the plant probably will not perish.
I have an indoor corn plant that was over watered then let to go bone dry. Can it grow again? This tree was fine 6 months ago, but now it has lost all its leaves and the cane is brown but not brittle. Can I revive it?
if the mass cane has lost all its leaves, I doubt that there's any real life left in it. If the canes (by canes I'm guessing you mean the green stems, or heads, since the canes are the large straight pieces from which the heads sprout, and these are always brown) have turned brown, they're dead. Mass canes can recover from 6 months of no water (I've seen them do it,) but they can be killed by several weeks of soaked roots. The key to success with them is to test the soil moisture all the way to the bottom of the pot. Test moisture with an electronic meter, or a simple wooden dowel or bamboo kebob skewer. The moisture level should be very slightly moist; unless the plant is in very low light, then the level should be completely dry.
Stems on my corn plant dried up and have dried hollow holes now. There were two trunks and one was rotted or something. I repotted the other. I noticed a few days later that where the new stems were growing at one time were dried up and brown. I went to touch it and it crumbled in my hand and now has a big dried up hole. The top part of the plant still has green leaves but they are not looking very good look soft and saggy. I am afraid it is dying and I don't know what to do. Please help!
I suspect you may have over-watered your corn (dracaena) plant. Drooping or yellowing leaves indicates over-watering or poor drainage. I recommend that you repot your plant in fresh soil after inspecting (and treating) the roots for root rot. More information on root rot can be found here: https://www.gardeningknowhow.com/plant-problems/disease/treating-root-rot-gardening-tips-for-housplants.htm
Your plant may be past the point of saving but this will give it its best shot for survival.

Leaves are turning yellow and brown.
It is likely that they are staying wet for too long. This looks like the start of a fungal infection. I would recommend applying dolomitic lime and wettable sulfur to the soil. This will help kill off any infection.
Let the soil dry out to down to about 2 or 3 inches before watering each time. This will help prevent future infection.
This article will give you more information on the care of Dracaena in general. This is one of many types, and they can look very different, but they all have very similar care, as explained here: https://www.gardeningknowhow.com/houseplants/dracaena/dracaena-houseplant-care.htm
I've had the plant two years it was 8 feet tall when I got it. It hasn't produced a new leaf in 6 months, before that it produced a new leaf regularly.
Your plant can grow up to 10-12 feet tall.
Hello.My indoor corn plant is about 6 feet tall and I have never replanted it. I fertilize when water couple times a month or so.. It looks healthy and I wouldn't want to disturb it. But 10 years in one pot? Is it ok?
It doesn't necessarily need it, but you can do this if you would like. Here is an article that will help you in transplanting larger houseplants: https://www.gardeningknowhow.com/houseplants/hpgen/repotting-a-large-plant.htm
Hello!! I have two identical corn plants, one is thriving and looking healthy, but the other is browning, has rips in the leaves, and is drooping almost. Wondering what could cause this/any care tips? Thanks so much!
There are some concerning markings on your plant.
I would first isolate the plant from other plants.
Check watering first; inconsistent watering and lack of humidity can cause leaf issues.
They can also be sensitive to salts in water so water with distilled water or let the water sit out on the counter for 48 hours before using.
This also could be leaf spot disease; either virus or bacteria.
