You may need to stake it, or support it with a cable from the brick wall.
Make sure you do rotate the plant to ensure even growth.

If these are outside, then possibly. If they are in window light, then you won't, usually, have to worry about sunbleaching.

This can also be caused by overwatering, or not letting the soil dry out just a touch before watering again. The most common cause of what you are seeing is, exactly, this.

If moving to a less heavily lit spot doesn't help, you will want to look to a fungicide.

Q. Something ate around the stem of my dumb – cane how do I save it?

The plant lives in a pot outside in Florida. Except for the stalk, it looks healthy- still healthy leaves. When I was moving my plants I noticed the stalk is brown from about two inches up from the soil to about two inches below the first leaves-maybe 6 inches of brown dry stalk – looks like something was eating it. It is narrower diameter and still firm in this “eaten” area. Above and below are healthy green stalk. No sign of bugs or holes in leaves; plant looks healthy. What should I do?

Q. What is this on my dieffenbachia?

It’s tiny and dust like, almost like saw dust. The plant is otherwise very healthy.

Those are aphids and they suck sap from your plant. You can wipe them off with a wet paper towel or rinse them under water. You can also use insecticidal soap or Neem oil. This article should help:

Q. should I cut the blooms off my dieffenbachia

I recently cut my dieffenbachia plant and now it is forming blooms. Should I cut these off?

It will not hurt the plant at all to leave them on. Taking them off, however, will allow the plant to continue to grow leaves and stalks a little faster.

Q. Dumb Cane care

I can’t get my dumb cane to grow. I was overwatering it last year when it was 1-1/2 ft tall, which caused mushrooms to grow, now it won’t grow.

The pot is too large for the plant. When the pot is much larger than the plant, it gets too much water, because of the large surface area. I would get a smaller pot and repot in fresh potting soil. Then get on a regular feeding schedule if you aren't on one. Here is general care of dumb cane:

Q. I have one Dieffenbachia that grows straight up with very little growth on the stem. It looks like a stick. How high should I allow

it to reach, and when and where should I prune it back so it will fill out? I’d like to have a lush plant but I’m afraid of where to cut the stem so that it starts to bush out. It’s about 1.5 foot right now but just a stem with a few little leaves.

These will reach about 6 feet before they will want to be pruned. I would look into why the leaves are falling off while it is this small. There could be an underlying issue, and I'm afraid that your photo did not come through, so I can't see it to help you.
