A friend propagated this plant from hers and it's been doing really well with tons of new growth. Today when examining the new leaves, I saw little bubbles at the edges of the new leaves. This pic shows the worst one. What is it infested with?

Looks like scale? Are you able to scrape it off with a fingernail?

It can show up on other plants in the area of this plant, keep your eyes open for the scale on any plants near this plant.

I remove scale by hand and dispose of them in the trash. If you have a huge infestation smothering products like insecticidal soap and horticultural oils can take them out. You must spray the product on the scales to kill them.

You originally called them bubbles. Are they wet if you touch them? I've had plants that do emit water from leaf edges and tips. In particular, my diefenbachia does that. That is totally normal.

No they kind of crunched when I pulled a few off.
I washed the leaves with diluted dish soap...and i'll watch it closely...hopefully this will be okay...😲
@oblique yes I think so...you could be right but it's so tiny I'm not sure. I've removed all from leaves and don't see anything on stems...I'll keep an eye on it

Hopefully it's just dried residue from guttation (like Karen described, the drops of water.)

guttation Hurray! That's the word I was searching for, yes. I had seen this as an answer to a question a while back. Thumbs up

@purplein
I noticed today the leaf that had the most "bubbles" had new drops of water starting again so I think you're right...I just wonder why they turned crusty like that. I've seen it before on philodendrons but always easy to tell it was water. Anyway I'll keep an eye out for scale but otherwise assume it's just guttation. 🙄

The guttation fluid comes from the xylem and contains mineral salts and other substances that are left behind when the liquid dries, so that would explain the crustiness.

I'm so glad it's that, and not the scale or any other problem. It looks like a beautiful plant! I used to live in an area where I had it outdoors, and it bloomed and fruited regularly. I may have to get an indoor one now. I do miss having nice large plants inside.

Thank you! Yes it is beautiful...I'm in Canada so I have it in the basement right now where it gets a daily beam of light and it's doing so well. I've named it the audrey II 😁

I think I'd buy it a plant light and move it upstairs where she could be shown off! Plants make a long winter so much easier.
