Ugh! My corn plant has some kind of pest. I do not see anything moving, all of the tips are brown, there’s white eggs everywhere but I don’t see anything. I’m not sure if they’re spider mites or gnat eggs. Please help!

I’m fighting the second battle in a protracted war with orange aphids. They appeared again at three weeks. I used insecticidal soap after knocking most of them off with a garden hose the first time. I used ant spray this time paying attention to applying it under the leaves where some were hiding. This is the only plant with aphids. This Hoya Multiflora lives up to its name by continually putting out flowers. There are several peduncles in bloom. New growth is very attractive to aphids.

Hi everyone! Can anyone help me with my Philodendron ‘Green Emerald’? I brought her from Montana and was green and full of leaves (6 months ago). She use to get filtered sunlight in my home (about 4 hours a day and in window) but was starting to get yellow leaves. I moved her under a grow light (12 hours a day) but just kept getting worse. I watered with hydrogen peroxide to make sure the roots aren’t rotting. But I’m not sure what else to do. Any thoughts? Thanks!

My satin pothos’ leaves are turning yellow, curling, and dropping. Her vines have grown super long but no new leaves. Worried about her, and she’s over two years old. I repotted her last month, has drainage, not sure what kind of sun she needs, I’ve read a lot of mixed sunlight recs, some say shady others say their pothos love direct sunlight. Please help me!!! xoxo Katie

Hi! I’m new to this app, looking for other houseplant nerds like me, but ones who actually know what they’re doing haha. I have had this monstera fern for over four years now, she used to grow fast, healthy, new leaves, but now she has stopped any new growth and has started to yellow and brown at tips. I’ve had to cut off several completely yellow leaves too. I repotted her over the past month to a larger ceramic pot with drainage, she had no root rot when I repotted but I was surprised by the small size of the root mass (for four years I was thinking it’d be a lot larger). I have her facing an east window, but I’m worried this is too much sun. Please Let me know what I can do to save her and help her, she’s my baby. My best friend in highschool gave her to me so she’s very important😭🌱🩷 Thank you soooo much!!! xoxo Katie

Hi guys!! I have a lipstick plant that was doing really well, but I noticed that the new leaves growing on them have these really weird yellow spots on them. It's not on any of the older leaves - just the new ones! I was scared it might be thrips or other pests but I did multiple, very thorough checks and there are no pests anywhere, including on my other plants. I switched to bottom watering recently because I wondered if maybe it was being underwatered? Otherwise I have no clue what to do about this or if it means the plant is unhappy :( any help or advice would be greatly appreciated!!!

I have this beautiful raindrop peperomia that has grown so much since I got it last April. Recently it’s been pretty moody. The leaves are going soft and growth has stopped. I repotted it and moved it to a brighter location, and it went back to normal for a week or so. Now leaves are getting soft again, and I’m not sure what the issue is. Please help this is one of my fav plant babies!!!

PLEASE HELP! My string of dolphins has had leaves and some branches starting to dry and rot. The app hadn’t marked it yet for watering, but since the soil was so dry, I decided to water it, it’s now been three days and not looking much better. I’m afraid if it’s root rot somehow, or if I just need to give it more time to recover from a drought. Any insight or advice on which may be the case would be greatly appreciated!!

Is this pests or sunburn? I just got myself this plant from a nursery over the weekend and picked it because it has new growth on it! In the nursery I didn’t notice how bad it looks cosmetically. Now that’s its home I have been meticulously inspecting it trying to see if it’s pests? If it is I haven’t found any myself, the leaves are also a bit dirty because my kid recently knocked this plant over. If you see any indicators of pests please let me know maybe it will help me to know what to look for next time

Hello everyone! I recently purchased a Tradescantia from a nursery, and just a few hours after bringing it home, I noticed that the leaves started to curl under and looked a bit dry. The soil feels quite damp, so I'm waiting for the right time to water again. My apartment doesn’t get much natural light, so I’ve also purchased a grow light to help with that. How can I make my plant happy again? Thanks in advance for any suggestions! :)

I don’t know what is happening to my fig plant but it’s not snails. I have checked the leaves a million times for any insect but I cont find a single one. The only thing this plant has is fungus gnats. I don’t even know how to help it.

Hey - so my boyfriend’s spider plant keeps having so many babies that our houses are overflowing with them! I find them so low maintenance and they survive so easily…but I brought one to work thinking it would be the same & the leaves are going grey and closing up?! Any ideas why/advice?!

Can someone tell me what’s wrong with my Corn plant? It just keeps progressing. It was one or two yellow spots and now the leave tips are turning brown. I’m very careful not to overwater it, but have been watering it with filtered water instead of distilled water. I also use a light meter app to tell me if it’s getting enough light. Is there anything I can do to help it?
