My succulents all of a sudden began loosing all their leaves and don’t have any new growth. This is happening in 3 separate plants (same species), has this happened to anyone else?

Hi! My darling fucus allii has whitefly buzzing her, I tried my best to clean every leaf with insecticide soap, added a sticky trap, and seems to have taken control of it, any step I missed? Any suggestions you might want to share?

Help… first terrarium… and I think this is mold? It looks kind of web like, but it also reminds me of cotton candy… any advice on how to address it?

My plant was inside a decorative planter. It was still in its original gardener’s pot. When I watered it, I picked it up to drain any excess water as I noticed it got beyond its saucer. Beneath the saucer, I noticed these larva(?). What is it and why was it inside a decorative planter under the planter saucer? I immediately repotted my plant, rinsed it, and sprayed its roots with Neem oil. But I didn’t see any bugs/larva in the soil.

So I was looking at my plants and I noticed that there were some fungus gnats flying around a few of my plants so I asked a friend what I should do and she said that I should spray the plants with soapy water. I wasn't 100% sure about the decision, but I did it anyways. I sprayed it on my succulent my spider plant, my monstera, and my cactus. Today I noticed that the cactus is on the verge of death and looks like she like deflated 😭 or something. Did I spray too much or does soapy water kill cacti? The other plants are fine, but there are still some fungus gnats :/ Is there any way I can save her?

I started growing an avocado tree from the seed of a haas avocado a few years ago. I sort of just left it alone and watered it when it needed to be watered. It got really tall with no branches because I never pruned it. I’m thinking about throwing it out because I think it has pests on it. I don’t do much with plants so I don’t know if they are bad or harmful. Help would be appreciated! Thanks.

Any thoughts on this peace lily? Moderate light and warmth, watered and misted. Looks a bit wilted! TIA

poor girl is on the brink of death. she had 3 new leaves for the first time this growing season. one more is on the way. Any idea why they’re so shriveled? I have them on a north facing porch but she is in the shadiest area. The humidity outside caused her to have more growth, but how do i stop the shriveling? I have tried tropical plant food, bottom watering with distilled water, and I repotted her for the 1st time a while ago.

So I have some plants in my office at work and today as I was “inspecting” them I noticed what looked to be a mealy bug. I took it off the plant and snapped a picture of it “for verification”. So now my question is what should I do? The plant looks super healthy and I do not see anymore on there but now I’m paranoid that the other plants I have (which are across the room) are going to get infected also. Advise please.

I’ve been using neem oil but the spider mites keep getting worse, is it possible that it’s something else? Any advice is appreciated

What is happening to my Calidora Elephant Ear??? Leaves are drooping and breaking where I have the wire but there’s new growth as well in the middle. Is the pot too small? It’s currently in a plastic pot inside a terracotta one. I see some roots on the top of the soil. The soil is fairly moist. Not sure when was last time that I watered it though. The plant overall has never kept more than 3 leaves at the time. They all turned yellow and slowly died like it’s happening to the big yellow one. Please help!

I’ve had my fiddle leaf fig for about eight months. Sometimes it seems to be doing well, and sometimes, like lately, a bottom leaf will turn yellow and drop off. After reading a few posts here, I checked the roots, but I don’t know enough to know whether this is normal. it looks like there are some whitish maybe mold areas at the bottom of the pot? The roots look healthy but if they are coming out of the bottom, does that mean I should re-pot? It is directly in an east window and I water it once a week. I have sitting in a larger pot on top of that little grate for drainage.

Recently repotted my spider plant because he was root bound in his old planter, he’s been watered once since the change and has been dropping an insane amount of leaves since then. The soil is still damp but the dead leaves are more crispy, he had big healthy roots when I repotted him. I’d repot him again if I wasn’t afraid of stressing him out, can’t find any signs of pests. Any guesses as to what’s wrong would be appreciated, he’s my oldest plant and I’m gonna be devastated if he doesn’t make it

It looks like black mold at the base of the Dracaena leaves. I’ve only had the plant for a month. Any ideas what this is? Thanks!

Any ideas if this could be a pest. I’ve looked at it under a magnifying glass, no head or legs visible, not moving. Could it just be a piece of moss or something I need to treat?

Is it normal for this dracaena to lose this much leaves? Never had this problem before, what do I do?

I found what looks like 2 single adult thrips on the underside of my Money Tree. I used my phone flash light and inspected closely. That’s all I could find. I immediately removed from the room and sprayed heavily with insecticidal soap. The plant is about 1-2 ft from other plants. All those plants have been treated with systemic granules and I haven’t noticed anything. I actually didn’t see much of physical damage to the money tree leaves or anything. How likely is it that I caught it at the very early start and what do I need to continue looking for?
