Plumeria help! I’m looking for any thoughts on why the leaf is discolored? It wasn’t yesterday. Any thoughts on the black spots of tar looking substance on the trunk, branches, and under leaves? Also wasn’t there yesterday. Only thing that was there yesterday are the white spots on the other otherwise normal leaves, which I was trying to figure out what those are as well. It’s new, in full Sun, has only been watered once in about two weeks and plan to once a week.

I’ve had this plant for about 2 weeks and the new leaves still haven’t opened. Is this normal? She’s under a grow light 12 hours a day and I water about once a week

Just bought a miniature rose about two weeks ago. Noticed it started getting a white powder on some of the leaves. When I looked into it I learned it was a type of fungus. I’ve been able to prune the infected leaves off and the rest seem healthy but I don’t want it to come back on any of the others. Does anyone have any tips on what’s the best thing to use to prevent it?

My snake plant is super wilted and idk why :( I repotted it last week and it’s been fine up until the last few days. Someone said it’s just growing but it’s most definitely wilting now (unless I’m just being dramatic?) but idk it looks sickly to me, the stem parts of a couple of the larger leaves got super weak so I pruned them but now they’re all that way and won’t stand up really at all

I inherited this plant from a friend. Im not sure what is going on with these leaves. But are they bad enough that should I cut them off? Other than these the rest of the leaves are nice and green. I don’t understand what’s going on with him 🥲 are these spider mites?

What should I do with this part of my ZZ? It was a part that I had to cut off months ago but this piece still hasn’t regrown. The rest of the plant is healthy and there’s even a new shoot. Should I cut it more or just leave it?

These bumps just showed up on these few leaves that are new growth. Anyone know what this is? If anything?

These spots recently showed up on my alocasia poly. Should this be something I need to worry about? I recently repotted it and I’ve had issues with the rhizome rotting at the bottom. If the issue continues I’ll probably just seal it back up again with hot glue but it was hopeful I wouldn’t have to do that.

No changes have been done to placement or potting, unsure what’s wrong

Help!! I'm at all loss. Anyone know what type of mite or pest this is? I thought spider mites but there was no webbing and straight rubbing alcohol did not touch them. They just walked right through it. Captain Jacks dead bug also did not work. This was taken 10 mins after dousing the plant in Captain Jack's. It's a video I had to screenshot since I can't post videos here

My Jade plant, Jessica, has been having a tough time though she still appears to be growing okay. Looks like she keeps getting chomped, presumably by the squirrels or opossums I know live in my apartment complex. Any tips for preventing her from being a snack? She’s also had bugs — thrips? Small and black—for quite awhile despite my using Captn Jacks Dead Bug on her twice. I’ve also used toothpicks to scrape/pick them off once a week or so when they get bad. Any tips on complete removal of bugs? And finally, many of her leaves are black and speckled. No, those aren’t the bugs themselves, the actual leaves are getting some lumps and spots. Mostly on the underside of the leaves but some on top side too. Not sure if this is because of the bugs though or because of the pesticide? Any ideas? Thanks a ton!

Can anyone help diagnose the problem with my cherry tomato plant? Water every 2 days, in sunlight for like 10 hours a day!

My monstera is so flimsy and just sad looking. It’s been sad looking since the day I bought it and I brought it home, inspected and repotted a few weeks ago with fresh, better soil and she hasn’t made any progress. It has a lot of mechanical damaged leaves and the bottom leaves have slowly been yellowing. I’ve lost a few smaller leaves lately at the bottom. What should I do with it?

Can someone tell me what’s wrong with my weeping fig plant? She’s not thriving at all. I had to repot her today 8/4 cuz I noticed white mold? in the soil. She has cactus fast drain soil from miraclegro. I water her consistently but wait until the soil dries out before I water her again. She’s next to big windows with lots of sunlight. How do I fix her?

Help with cat palm! My cat palm has been unproblematic until recently where I’m seeing some leaf turn yellow and some with some black spots on them. It also looks like it’s leaning. I don’t overwater it and I make sure it’s drained. I wonder if it’s cause it’s sitting under a vent. I do see some new growths though! Any suggestions/ideas would be greatly appreciated!!
