I’m pretty sure this basket I got around Christmas has become a mealy bug haven. There are several plants in it, and I’m not sure how to proceed. I’ve been killing all the adults I can find with alcohol, but I’m thinking I need to I unpot and separate this, clean up the roots, and repot the various plants in their own containers. I’m pretty new to all this, so any advice would be appreciated. How would you go about saving these plants? Thank you in advance!

The top of my cactus seems to have died. Do I cut it off or leave it?

Anyone know why the leaf is turning brown at the edges? Also, the stems are red right now. A few weeks ago, they were white/yellowish. Thanks so much for any help and advice!

Is my African violet diseased? It looks like the new leaves growing in have discoloration too. But it’s blooming and seems happy otherwise. I’ve had it for a few years and haven’t seen it do this before. It’s in a self watering pot, repotted probably 6 months ago. My cats sit on the window sill next to it which is why it’s covered in hair 😂 (Last picture is a few months ago)

Hi all I was wondering if anyone had some guidance on my majesty palm? I saved it from Home Depot it was root bound and in a tiny pot, I brought it home repotted it with palm soil and watered the parched soil. It was greening up and pushing through new leaves a few days later the lower leaves started to yellow is this normal?

I recently found these white patches stuck to my poinsettia and I’m not sure what they are. I thought they were mealy bugs but they don’t seem to be alive, and they literally feel like they are glued on. Does anyone know what this is? Thank you!

I’ve found these little tiny white bugs crawling around my plants. Not spider mites. What are they and how to I get rid of them?? Google is worthless.

Any Epiphyllum lovers out there? I inherited this large orchid cactus a few months ago and its leaves are very dehydrated. I’ve tried doing a soak with fertilizer, but didn’t want to let it linger as I’m afraid of root rot. This thing is massive, 4ft wide. I love orchid cacti and would be so sad if it doesn’t recover.

Can anyone help me know what’s wrong with my firethorn? It was doing well after some pruning and now the leaves look rotten?

Just bought this monstera a few weeks ago- just trying to figure out if this is a sunburn spot on my plants’ leaf or something is wrong with it 😁 gets watered once every two to three weeks, so its about time for watering again soon Edit : I do have a grow light coming in for the plants as they’re pretty distanced from both windows in my room

Hi everyone i got this Marble Pothos about a month ago and since then I’ve moved her around a bit trying to find a home and she’s been developing yellowing leaves and looking droopy?? I just hung her in this new spot but I was wondering if there were any other reasons for her change? I’m hoping it’s as simple as overwatering.

This beauty, Medusa, is gnat infested! And they are everywhere in my office 🫤I’ve read that diluted hydrogen peroxide could do the trick on the soil and leaves but not flowers? Before I try wondering about alternative solutions and/or others’ experiences.
