Any recommendations for my gardenia? I bought it about a month ago. The flowers dropped first, and now some of the leaves are starting to turn yellow. It’s currently in bright shade and gets a little afternoon sun. Any ideas on what might be causing this or what I should do?

I adopted this Zz plant from a friend who moved to a different state. I've had it since around the middle of November 2025. I'm not sure when the last time it got repotted was and this is my first time owning one of these plants. I'm just wondering if I should repot it now or wait. There's 1 drainage hole in the current pot.

My beautiful 12 year old hoya! We moved house six weeks ago and now a lot of her leaves are fading, she’s got brown spots, and a few completely yellow or brown leaves. There are also a couple of leaf patches that seem kind of transparent. Would it just be shock or sunburn or over / under watering? Or some kind of pest? I’m worried because I found a mealy bug on her neighbour, but i checked all her leaves and stems thoroughly and can’t find any bugs or sticky stuff. Also checked her roots and they seem super healthy with no rot or anything. There was also one white clump of something that might have been webbing in between some leaf stems. (She was a lil dusty so it might have just been cat hair but it was like 2am and I’m an arachnophobe and my brain convinced me it was either webs or a whitetail egg sac so immediately cut off the stem and binned it). She’s been living on neglect and inconsistent watering for most of her life before i knew better. I think i even had her in a pot of peat with no drainage at one point 😬 but she’s always looked pretty healthy and happy until now!

Hi, My philodendron black cardinal fell & damaged one of the stem/leaf area. It’s not fully snapped & the bend is closer to the base of the leaf area. I’ve currently staked the area to give it more support, but should I just cut away the area? Photos are of the bend with/without stake. Thanks!

Do y’all guys know what happened to Cheese my monstera plant? Two of her leaves are a lighter color than the others, I am guessing it may be too much light but I don’t know. I hope she gets better🙏.

Is this mold growing in my soil? (I know it’s dry. I just took this out of the cache pot to water it.)
