| I've had this euphorbia for well over 10 years, and always assumed the brown/tan formation was a sign of age. But I also noticed some other plants in my home having some growth on them. I've attached a picture. Across the top is the stem of a dracaena deremensis, under it to the right is the euphorbia, on the left is a dieffenbachia (the cane on top, back of leaf on bottom). Is this scale? If so, how bad is it and can it be cured? If not, what is it? Thank you. |

| The images aren't large enough to be totally helpful, and I lost my Mr. Magoo glasses somewhere. But I don't see anything that looks like an infestation of scale insects. Any chance of more detailed (larger, closer) pictures? |

| Click the link, sorry the site only allowed that size, I should've linked them to begin with. |
Here is a link that might be useful: Scale

| I still don't see anything that looks like a scale insect infestation. |

| It's easy to check. If it's just the natural bark it will not rub off with your nail. If it's scale it will wipe off and you will see the oozy brown body under the shell. |

| Thank you for all your help, I hope it isn't scale and I'll just wait and see what happens. |

| I have seen damage like that before on plants like that. I think it is due to too much moisture or a lack of dry air. It could be some kind of fungal thing, but it happens frequently in San Francisco. I have seen it at the best nurseries. |
|
| It looks like old physical damage to me. It looks like the plant grew some corky tissue to close the scrapes, damage etc. |
|
| Succulent stems do that with age. |
