I noticed the brown spots this morning so I am not sure how long they have been there. I use tap water (soft, that has been left out for 2 days to evaporate chemicals) for years and never really notice these brown spots. In addition, I changed my soil about six months ago. Also, I never fertilize the plant.

Should I unpot it and check the roots?

Chemical toxicity can build-up over time. Softener salts, lime, and fluoride can't evaporate from leaving water to sit, and most municipalities now use a form of chlorination that doesn't evaporate, so that's a lot of stuff coming from the water. That could be a factor.

Did you use a soil with moisture control crystals? Did you remove the old soil, or just put more in a bigger pot? Does the pot have a hole in the bottom? Exposed to cold temps?

No moisture control crystals. I removed the old soil and repotted about six months ago. Yes, the pot has holes at the bottom. It has been indoor always, never exposed to outside coldness. What should I do?

Found another leaf on the same stalk having problem:

Are you able to add a pic or two of your whole plant?

The info here might help you gauge what's going on under the soil surface:

Here is the pic of the whole plant. Also, corrected info: The three leaves are on the same shoot, not "stalk" (i.e. trunk, sorry I didn't know how to describe it). Leaves on another shoot on the same stalk/trunk are perfectly fine.

Ken, imo, you're giving your Dracaena the best care.

Rotate the plant.

Are the brown spots soft or hard?

Since the spots are on one stalk, it may be defective. I've seen the healthiest Dracaena's that had one marked/defective trunk/stalk.

See if spots widen. If you want to rid the brown spots, leave a tiny portion, about 1/8", of brown on...

The brown spots are papery like semi-dried leaves. Not sure if it's soft or hard. But if I must, I would say it's soft rather than hard. I hope I can find out the reason to prevent the problem from spreading (if indeed there is a problem).

Also I tested the ph of the soil. It's 7.

Ken, although spots are brown, are they semi-translucent? Like weaved cloth? lol

As you stated, 'IF' there is a problem, it could be a bacterial. There's too many types...to be honest, I'm unfamiliar with them.

Some of my plants, 'mostly Dracaenas' get similar spots. I usually remove the leaf, or if on the edge, trim.

My Dracaena, 'Song of India,' is outdoors. Last week, temperatures dipped in the 30's. I noticed several brown spots yesterday.

Whatever, I hope your plant pulls through. As I stated earlier, other than the few spots, your Corn Plants looks terrific. Healthy foliage. Good luck.

Now that you mentioned weaved cloth, I checked the spots again and they are not semi translucent. Totally opaque. Any clues?

I wouldn't worry about a plant that looks as good as yours, and from what you described about its' care. It's rare to see one of these with every leaf perfect.

Soft and opaque. No, I don't. lol

Ken, please check your plant daily. If it spreads, most likely it's a bacterial problem.

When you have time, please Google, Fusarium leaf spot disease.

It could be sun damage. Maybe those leaves are getting hit with some direct sun in the afternoon. Your plant is beautiful and looks very healthy. I wouldn't worry about it.

Hi Birdsnblooms! Did you get my message?

Just try to update what I found out so the info might be helpful to others:

Found another post here titled "Brown Leaf Spots on Dracaena": That 'cellular' criss-cross line effect is a sure sign of cold damage. I compared mine to the pics in that post and then I realized this past chilling weekend (in the upper 30s) we opened the windows for about 2-3 hours and the plant was next to the windows. Looks like frostbite to me now. I didn't know the plant would be this sensitive to coldness!!! Hopefully only three leaves are affected.

But thank you everyone here who helped me!

Ken, better a little frosted than diseased.

That's good!

BTW, I still have a Dracaena outside...That guy is coming in today...

Any help please? Ive had it for about 5 months. Not sure why this is happening. Should i repot? Its in the same container. Tge top soil is really dry. But i just watered it 2 times in the last week. I dont want to over
