This small black mark is showing on a new Thai constellation leaf. I’m hoping it’s not the start of something nasty - any suggestions?

What are these insects? I bought this monstera Thai constellation from Rona but they were in self watering pots so I was going to repot them, when I looked closer today I see all these little bugs running and flying around the soil.. I looked under the leaves because I thought pests usually stay there but they are only in the soil and around the pot.. I’ve never dealt with pests before with my plants and I’m worried that they already flew to my other plants and are infesting them too, what do I do? Are they going to fly to my other plants,, and how do I get rid of them? Are they eating my plant? I don’t know💔

Hi everyone, I am wondering what kind of bug this is? I initially thought that it might be thrips, but after I talked to someone they said that they think it is white flies. Should I treat my plant to get rid of them? Probably, but I thought I would ask for another opinion (or a few) before I do it. (Ps the plant is a Euphorbia pulcherrima {poinsettia})

Ummmm. The Sun? Am I crazy or is the Sun just a bit…different this year. So hear me out, I plant Mammoth Sunflowers and this year I took to planting American Giant Hybrid? Sunflowers. My Mammoth seeds are generational, so I never repurchase those. The sun is literally baking them alive but the AGH seems to not be as affected. My cactus got burned. Fernando and I go way back we do and he has never been burned in a single afternoon. I’m located in Lubbock Texas on the High Plains. I can soak the soil and by midday it’s cracked. Im not crazy I swear. Is anyone else of the same mind???? Christ on a bike it’s hot out here.

My Monstera adansonii just put this new leaf out two weeks ago. I initially thought this light green spotting was the new leaf just darkening in color, but the spots have gotten lighter while the rest of the leaf has darkened. I did just move to a new apartment two months ago, so I think they (and I) are still getting used to the new climate in this unit. Any ideas on what’s up?

Can anyone help me diagnose my bird of paradise? Some of the leaves are browning, while others are curling. Some information about her…she has drainage holes, watering according to the schedule, and is at a window that gets lots of sunlight in the morning but tapers off as the day goes on.

I just moved into a new apartment and I’m noticing growth on the top of my soil and on the outside of one of my pots. I’m very confused. Is it a type of fungi? Do I need to be worried? It looks kinda like frost.

Does anyone know what this stuff is on the intersections of the stems? I don’t know if it’s a fungi. It’s mostly a hard substance, but I can kind of put my nail into it. The plant doesn’t seem like it has pests, but I feel like it’s been dropping a lot of leaves and maybe the stems attached to this substance seem to be shriveling? I got this plant from my aunt about 2 years ago, so not sure when it was repotted. I was thinking of doing it today, but want to know what this is first. I haven’t noticed anything unusual but my gut says I don’t think this should be here. Should I be concerned? The leaves and flowers that dry up and fall off seem to be normal Update: Planta doctor says it’s corking (and a bit overwatered). I don’t know anything about corking, but it says that’s fine. Is that correct?

🆘 Infestation!!! HELP - plant gurus wanted! I am a beginner and may be a little in over my head right now 😭 I picked up this Dwarf Jasmine Tree plant from Home Depot some fourish days ago. I’ve repotted it, given it plant food, some nice light, and a couple waterings. It looks nice and seems to have adjusted well, but I’ve noticed these greenish/blackish pests, small white specks, and white chalky residue on the leaves. I consulted Planta AI and it identified the problem as “aphids.” I’ve tried to take off as many pests and as much white residue as possible with a wet paper towel and a little dish soap. As per Planta’s advice, I’ve also doused it in Neem oil. These pictures are after all of my efforts. Should I go on a pruning spree on the clusters of flowering buds, where they seem to congregate the most? Is this plant a lost cause? My pothos is doing well, my periwinkles are doing okay, but me and Jazzy, WE ARE IN PERIL!!!

We had major thunderstorms last week and my bird of paradise received way too much water but is that what has caused these leaves to brown or is it something else?

Hi! Has anyone ever used Zevo plug ins by their plants to get rid of the tiny flies? Do they work?

I live in Texas and have a Morning Glory that is no longer blooming. She looks healthy and is growing. Any thought as to why it is not blooming?

Hi there! I live in Fl where the highs of the day are reaching between 92-98 degrees and almost my whole collection is outside. Everyone except my anthurium are doing well, does anyone know if I move the anthurium inside will they be okay? I have good lighting in my bedroom where a monstera does well. Should I get a humidifier?

Newbie plant mom…only a few months. My Camille, Philo and Pothos are looking not too happy. I used a commerical bag of indoor potting soil and perlite. I water the Pothos and Philo every 5 days, Camille 8 days. Liquid fertilizer every 3 weeks. Grow lights are on for about 12-14 hours per day.

New Gardener

Hello, I’m a new gardener. I planted azaleas in wonderful new acidic soil covered them with fresh pine chips approximately four weeks ago. I have been good to water them nearly daily at the roots Over the past week and a half, we have had a lot of rain so I backed off on watering. Leaves on my azaleas have started turning yellow with black spots. I thought it was too much rain, but the soil seems dry now. I sprayed them with neem oil 2 days ago, but the leaves continue to turn yellow with black holes and drop. please help. One of the azaleas has had a bloom over the past week so I thought they were beginning to do better. But they’re getting worse I don’t know how to prevent them from dying. They are looking sparse. Thanks for your expertise.

ALGAE! "Kelp" Me Out, Please!!! I was watering plants today and I will admit I've been a bit neglectful the past week... when I brought Bubble into the kitchen I found that the bowl she was sitting in had a LOT of algae at the bottom and a bit up the sides. I've never grown a plant in water before, and she's been thriving, but the amount of algae worried me because I'd been seeing her roots get a bit green for a while now - it was just never this bad. Her roots have grown like wildfire despite it all, and despite being green. I have her sitting in the only spot available for plants rn (we have limited open space and she's too big for her old spot) and it's right next to a west facing window, any other spots are too far from the windows. Is there something I can do to help her roots? I'd like to keep the glass 'bubble' type vase, but I'm willing to find a new one ESPECIALLY since I think it's soon gonna be time to upgrade her room. I already washed the vase with dawn dish soap and let in sit under super super hot water for a few minutes while letting Bubble herself sit to the side for a bit, and I tried to wipe off what I could from the roots. Thank you! (Photos in vase prior to adding new water)
