I recently repotted my Monstera plant and the leaves are drooping. I’m not sure if it’s going to die or not and I’m not sure what to do. Hoping someone can help!

Help! Two of my plants are going through similar problems. My mint is yellowing at the tips then turning brown shortly after (falling off while mostly yellow). This has happened twice now, once with a potted pretty large mint, which I took a good cutting from then propagated trying to same any of it. The mother plant died but the propagation has stayed strong. Until now, when its beginning to do the same thing. It has full light and is still in water? I've never had issues with mint before so a bit confused. The second plant is a small Monstera, it's in a mixed tropical soil from a friend and a terracotta pot, watered on schedule and partial light but I just keep getting yellowed leaves. Pictured are the second and third leaves I've had that have gone completely yellow with no explanation.... anyone have a clue?

I’ve just inherited this raven zz plant and when I got it home I noticed that (as well as needing some serious cleaning) a couple of the top leaves have been broken off. Will this hinder any further growth? What steps might I need to take to give it the best chance of growing healthily? Thanks!

Help! I am trying to save a dear friend’s Christmas Cactus, Anna Barbara! She was severely under watered. I have Anna Barbara in my home to save her. I have had her for about a month and I am not seeing any change. I have put her on a proper schedule. Repotted with proper soil. Any advice is greatly appreciated!

help! what is this white “fuzz” stuff on my pothos and how on earth do i get it off? at first i thought it was spider mites so i treated the plant for them, but there were no sign of spider mites other than the webbing. Then i thought it was some type of fungus, and i sprayed the plant routinely with diluted 3% hydrogen peroxide. Since that didn’t work i sprayed with undiluted hydrogen peroxide and it still didn’t go away. So then i decided to go completely soilless because i thought there might be something in the soil, but after i blasted the pothos with water, sprayed with HP and the let it grow in water for two weeks, it STILL appeared. The strange thing is that the plant doesn’t seem to be harmed, but i don’t know how safe the webbing is for humans and tbh it looks very very ugly…

Can anyone help me with my Meyer Lemon? It is in a SE location. I’m in Southern Arizona, nights have gotten down to 37 and days are 60-75. I don’t know if I should bring it inside? I’ve been following Planta as far as watering and fertilizing.

Found Mealy bugs on my chinese evergreen’s newest leaf. I have quarantined her and sprayed leaves down with a neem oil, rubbing alcohol, water mixture. I very thoroughly cleaned the entire plant the day i found them and I think i got almost all of them off. it’s been two days and i haven’t seen more, but is there anything else I need to do besides continue to clean the leaves regularly?

Does anyone know what's wrong with my ivy? Some of her leaves are browning and then they fall off.

My false aralia used to look like this. Pretty good. Now its leaves have turned a dark greenish brown and are crunchy. The soil was bone dry so I watered it but it isn’t getting better. I used to have it in bright sun but I heard that’s not good. So now it’s in shade with some sun. What’s wrong?

Overwatering or under watering? I would guess overwatering but the other leaves are not dropping at all, quite the opposite, still very springy and full! There are only about 3 leaves that are yellowing. Also, the one leave that has a brown edge does not feel crispy.. it’s still flexible. It is papery and slightly curling inward but just wanted to ask yall what you think! Haven’t looked at the roots yet but that’s my next step depending on what you guys think.

Found these brown spots on a couple of my Monstera leaves and not sure what it is. Can anyone help? I went ahead and cut them off.

My peperomia has had leaves curling and slow growth lately. Help!! Plant AI says overwatered but top soil is dry and I’ve only been watering as instructed. Could still be that but just wanted second opinion..

Hello everyone, my forest cactus is going dry and I don't know if it's because of a fungus or pests. The leaves have a whitish powder on top and the soil has a layer of like a spider web. I wonder what I can do to fix it? Thank you!

Any idea what is causing this?? My baby Pilea seems to drop leaves overnight. Before I went to bed last night she was fine, this morning I see this leave has fallen off and already browned/blackened. There are also these brown/black spots that look like cuts or bites?

Does anyone know why these two are always curled and droopy? The others look happy and fine, though the whole plant has been through a little repotting/overwatering/root rot situation. But they basically stay like this no matter if the soil is dry or not. I’m stumped.

Some of my leaves have browned and my succulent isn’t growing straight up:(. I’m sure the growing straight part isn’t as big of a problem but should I cut off those leaves? Or leave them? The browning hasn’t gotten any worse so I’m not sure if it had to do with the environment my succulent was in. Any advice on what to do about the leave or the leaning would be much appreciated!!

Recently got this Wisteria sinensis and it has been getting more yellow leaves now with black spots. I have another massive wisteria and it looks okay so far but wanted to make sure there wasn’t some infection? I don’t see any pests anywhere. Thought on how to save?
