Am having on-again, off-again issues with our burgundy Chinese Fringe Flower (Loropetalum). Any hints as to why it does this? It is regularly hand-watered.

My avocado used to be indoors growing in water and I moved her outdoors to soil, she’s got new growth my question is would anyone recommend snipping the brown leaves which she grew when she was indoors or just leave it be? Just don’t want to stress her out if not needed

I have a black raven ZZ that recently joined my collection, and I’m worried that I have it placed incorrectly. Currently it’s near a window, but not in the direct path of sunlight for a majority of the day. I’m a little paranoid after another plant died in a similar spot (pinstripe calathea) and wanted some feedback if this spot is appropriate

Hi! My coworker has had these bamboo shoots on his desk for a couple years, but recently they have become increasingly yellow and started producing this white dusty fuzz all over. Does anyone know what it is and maybe how to save the shoots?

Hello! My Pilea is hurting. Some of my other plants have thrips, though I haven’t found any on this plant and I am treating it. I have some gnats flying around and are trapping those too. I repotted this plant a few months ago and it has been doing really well… but suddenly the leaves are turning yellow, white, and brown spotted. This is the third leaf I took off and the least affected so far. HELP! What’s wrong with her and how can I help?

Hey y’all! So this spiral cactus just arrived. I decided to just leave her alone, no repotting for now. She looks worn out honey! I did notify the seller and sent pics. While I’m waiting on a response, Any advice?

Asking for advice and wisdom! I chopped my pink princess about a month ago and she’s been steadily rooting in water. Just noticed these brown triangular patches on her leaves. She is not in direct sun, so I’m feeling pretty confident they’re not sunburns. Any other ideas? Recommendations for what to do?

Help with my struggling orchid :( Hi! I’m pretty new to taking care of plants and could use some advice with my moth orchid. I’ve had her for a while, but she hasn’t been doing very well for the past month or two. A few of her leaves have fallen off, and the remaining leaves are pretty droopy/wrinkled and have some discoloration. I’ve been watering her and she’s been getting plenty of sun but I know she definitely needs to be repotted soon. I’m not super familiar with orchids yet, so I’m not sure if the issue is the roots, watering, old potting medium, or a combination of things. I added pictures of the leaves, roots, and current potting mix. Does anyone know what might be going on and what I should do when I repot her? I’d really like to save her if I can! 🥲🌱

My pothos got root rot. I accidentally left him sitting in his dish for water drainage when I watered him a week or so ago and I felt awful when I realized and tried to dry his soil out as soon as I could, but the damage was already done. He keeps losing stems and roots now and it hasn’t been getting any better, he’s really starting to look really bare. Any advice for anything I can do to help? I know the root rot is already there and there isn’t a whole lot I can do to get rid of it, but is there anything I can do to prevent it from continuing to get worse or to help him get better faster?

HELP!!! Just bought 2 Pentas today to replace my dead TROUBLE plants (Moonflower) from a local nursery. The first one went in fine. When I un-potted the 2nd, all this tiny, white bugs were in the bottom! What are they? Should I return this 1 plant to the nursery???

sun damage? not sure what the small little speckles are, they've don't move but can be picked off. they don't seem to be affecting the health of the plant. not pests. haven't checked the roots yet, hasn't been repotted in over a year. west facing window, she's sat here (about a foot away from it) since she's been in this pot. new leaves don't unfurl with this damage and most of the leaves don't have it at all despite being months unfurled. big spot in the second pic is not transparent, so not edema

My diffenbacchia has been fighting mealy bugs for 2 years. I’ve tried everything - repotting, sprays, washes… but every new leaf that comes up has mealy bugs in it. He just seems so limp and sad. I read that it may be worth cutting the whole thing back and propagating from the stalk. But given he’s had mealy bugs since he was a baby… I’m worried it won’t resolve the issue. Am I a terrible plant mom if I let him go to the grave yard and just find myself a new bug-free plant 😭

Help! I got gifted a pothos N joy because the previous owner couldn’t revive it after they nearly killed it. Now I’m trying to revive it and it’s been hard! I propagated some of its cuttings bc I thought maybe it needed some pruning, the cuttings are doing great but the momma is not. I’ve tried watering it a little bit more and it’s just not working! Please drop some tips or tricks I can try on this plant, I’m just trying anything because I don’t want it to die!

How do I help my sweet prayer plant? Her sister is thriving, but I woke up one morning and she was all sad. They are now in separate rooms. Can I save her?!

Anyone know why my spider plant is turning a pale green? Its propagations are doing it too even though they have different lighting conditions.
