That looks like mechanical damage, possibly done during the move. The other possibility is that some creature (grasshopper, caterpillar, etc.) started nibbling on it. If that's all there is and it's not happening anymore then it won't affect the plant. But you won't get rid of those marks.

Thanks. I am particularly worried about a bug infestation because my jade plant appears to have similar damage--see photos. I have been spraying my plants with a solution of rubbing alcohol for the last couple of days, any other tips or ideas about what this might be?

Allie - I answered you about the Jade plant on the C & S forum. For some reason, the thread still says "Be the first to comment." So I'm not sure you knew there was a reply.

Well, shoot. I guess my reply can only be seen by me! So let me repeat it - And I hope this one shows up!

Those little brown spots on the leaves are mechanical damage. And since you just moved, I'm guessing they were bumped and scraped a little and now it looks like brown scabs. It won't hurt your plant at all. They are quite good at healing themselves.

The marks on the stems is probably just aging. New growth is green and old growth turns brown, like any tree. So all is good there! You can really see the contrast on this plant that I pruned back heavily. New stems are green.

You mention that you are worried your new home may not be good for the plant. Are you worried about sufficient light? It looks to me like it hasn't been getting enough sunlight, and I understand that can be difficult when growing indoors. The internodes (space between leaves) is longer than it should be, so the plant has been reaching for light. (Cool how they tell us, right?)

My plant is outside in full sun all year. See how close the leaves are growing? And they aren't droopy.

You may need to correct the light in your home by getting some grow lights, or light bulb. I hope others will chime in and advise you on this as I have no experience with them. Depending on how many plants you have, it may be quite easy to do in a lamp.

Your potting mix looks pretty good. I hope the pot has a drainage hole. Other than improving the light, things look pretty good from here! So you can stop spraying with the alcohol unless you see the mealies return.

Good luck and happy growing!

Thanks everyone for all of your help--to be honest, though I'm not convinced it's merely mechanical damage. Partly because I was very careful with the plants during the move, and partly because a lot of this damage is rather recent. In the last couple of days I've noticed some more spots that look like something is really nibbling away at my plants--and that it's possibly hopping from plant to plant. Here's a pic of another plant (I think a kind of aloe) on my windowsill. In the last three days Ive seen these clusters of white that appear scraped into the leaves that definitely weren't there when I first moved.

Very worried about all of my plants and any further insights would be much appreciated!
