Perplexed here. My ZZ plant has two top yellowing leaves on one of the stalks. It can’t be due to overwatering because I water once a month and it’s in terracotta with a fairly chunky mix. It’s in an east facing window room but about 6 feet away from the window. However, I did just repot it, into a bigger pot since the rhizomes were squished in there. The old and new soil was dry when it was transplanted and I didn’t water it till now, about ten days later (which is a total of about 24 days without water). Could this be repot stress? Or an old stalk?

The first picture is a Swiss cheese I bought from Home Depot today and it does have webbing at the bottom of the plant but I did some looking and found a spider so I’m assuming all of it is from him and not spider mites? I’ve never had them before so wanting to make sure. The second picture is a ZZ plant I saved from Walmart clearance. There is white roots sticking out of the bottom but I do think it’s in beginning stages of root rot because I’m pretty sure I see some mushy dark roots hanging out as well. I’ll have to investigate better tomorrow. If it does and I treat it/cut off bad roots, any tips on keeping her healthy since she’ll be messed with while not acclimated? Also, should I just take off the damaged leaves?

Hi plant people! Can anyone tell me what’s going on with my pothos? It’s about two years old now and the new growth seems to be doing fine but there’s occasionally yellowing leaves near the top existing older ones and brown spots. I should add I’ve recently put it on a more regular watering schedule and put it outside for the warmer months. It’s on a west facing porch that has a roof and receives plenty of direct sunlight. My only thought is maybe heat or sunburn? It has consistently been in the upper 80’s and 90’s where I live.

Pony tail palm has mealybugs. I’m so so so sad. Luckily she was isolated from my other plants but I’ll have to check them all now 🥺

Hello! This leggy begonia is the child of a massive plant I originally got in a 15-in planter. It seems to be suffering from the same issue I had with the mother plant. It grows vertically but all of the leaves beneath the top third of the stalk shrivel up in this gray color and die. It’s in well draining soil with east facing light and I water it regularly. Any ideas what could be causing this?

I’ve had my maranta for a while and have always kept it in the same place, I haven’t changed anything about its routine and it was flowering and experiencing lots of new growth not too long ago but now it’s looking a little rough. Not sure why! Any ideas?

Back to this girl again! She’s not doing any better. I went on vacation for a week and no one looked after her. Two of her 3 leafs fell off while I was gone and then shortly after the third. Any tips of advice would be appreciated on how to revive her!!

Plant has thrips. Rinse her with warm water and wiped her leaves down. Isolated her and used some insect oil and soap.

My neon Pothos continues to struggle with mealy bugs. I’ve repotted it and treated it but they continue to return. Any advice?

New plant mom and I made a huge mistake in repotting my Calathea . I believe she is in shock and possibly root rot.. Can I save her?…

ANYONE KNOW WHAT THIS IS!?! IT LOOKS LIKE EGGS BUT I REALLY HOPE ITS NOT. My string of bananas has been having a rough time so I decided to give it some fresh fry soil and I took it out of the pot to find this… about to chuck this outside if I find out these are eggs 😭😭

Does anyone know what could be causing this to my jade plant. The weather here has been stormy the past week. Is it a lack of light? Pests? I haven't seen any bugs on the plant. The leaf is also turning a lighter green color.

My friend has this maranta plant (prayer plant) that she repotted because she noticed some leaf decay and yellowing. It hasn’t been in harsh sunlight and she waters it from the top. She is wondering what the issue is if anyone can help!

I have the WORST gnat problem with one plant in particular. I bottom water it since it’s one that needs to be watered a ton. I’ve tried the neem oil spray and it’s not fixing it fully. Any tips??
