Hi everyone, I need a little insight. I live in North Dakota where it gets very very cold this time of year, and even colder yet to come. And we only get 6-7 hours of light a day. I just started collecting house plants over the summer. I don’t know if my plants are dying or if they’re just dormant. All of my alocasias died, and some other plants just look so sad. Am I doing something wrong? Do they need more attention than what I’m giving? Any insight would be greatly appreciated!

Have some leaves turning yellow and some damage spots. Any idea what could be going wrong? I’m wondering if it could be a cold issue? lack of sunlight in the winter? Mites?

favorite remedies for rust fungus? I was told cinnamon could work?? it would be awesome if I could do it without chemicals as I have reptiles and such in the house.

Hello, I hope one of you can help me. I'm unsure if this is just a natural leaf death due to braiding, or if there's a disease present. My braided hoya a cumingiana has progressive leaf discoloration, on just one leaf! I'm concerned about spread, should this be fungal or bacterial. I've sprayed it with copper fungicide (Bonide) every other day for the last ten days. I've had this plant since April, and have watered it every 7 to 14 days depending on the weather. It was very happy until the weather turned locally in mid-November.

What are these white things? My plant looks overall healthy I just got these clear plastic pots so I’m not sure if this is a normal thing and I just never noticed??

Anyone have an idea what’s going on and how to help my Boat Lily?? She’s turning yellow and getting limp. I only water when the app tells me too, and I water until water runs out of the drainage. She was by the patio door, but recently moved it away bc I thought it was too cold there. But it’s literally the only place in my living room that gets am sun right now. Currently it’s sitting in a spot that gets indirect light in the morning and then it’s dark in the room most the day unless my lights are on. What are your guesses for what’s going on and how to help it?

I have 3 pothos, and they all have droopy leaves. Two of them have dropped a lot of leaves and have very slow growth. I water them often. They get plenty of light because they are in front of a south facing window. I don’t think it’s any sort of pests or bugs. Do you think it’s some sort of disease? Or overwatering? Here are the 3 pothos, the one on the shelf has the droopiest leaves and has dropped a lot of them.

Monstera delicosa (I think) - is this caused by spider mites?

Hi, both my peace lily and African Violet have been in my screened in porch until yesterday. I’m in NC and the temperature has varied a lot lately. I’ve been watering on schedule but I didn’t know if they all drooped like this from the temperature. My Monstera has already died as well. I’ve moved them all inside but didn’t know if recovery was possible.

Help with a diagnosis for my thai con please. I use my own soil mix in all my plants and a water meter so I dont think I’ve been overwatering. she gets regular fertilizer/ silica and I use timed grow lights to supplement during the winter and an infrared heater to keep the room temp stable. The windows are sealed with plastic over the winter so there isnt any drafts. My humidity stays around 80% . I preventatively treat all my new plants with spinosad and use bonide systemic granules in all my plants. I did forget to close the curtains but i dont think theres been enough sunlight to burn the plants (Im in Maryland). She has new leaf growth but out of no where these black spots are on three leaves. Im not sure what they could be or what I’m doing wrong here. If anyone might know, Id appreciate the help.

Help! I barely touch my ZZ and she’s been perfect for 3 years. Now she’s losing a ton of leaves. Her soil really dried out quickly right after I watered her last time (3 weeks ago-ish). How do I proceed? She has a grow light and I water once a month or so.

I need a Begonia expert! 😭 I bought an imperfect box from a plant store that had random types of plants in it. In it was a very sad Begonia melanobullata. I felt like it was overwatered. Possibly to help during transit so I’ve not watered it since it arrived over a week ago and it seems pretty damp at the bottom still. It only seems to have gotten worse and the leaves are going black and crispy 😭 i don’t know what to do to save it, if i even can, every leaf is like this. My cabinet sits at around 60%humitity. The only thing I can personally think of that it doesn’t like, is the grow light? Any recommendations? This is my first begonia and probably the only one I’ll ever have. I REALLY WANT TO SAVE HER.

The app is saying my birds nest fern is over watered, but I don’t think that is the issue. Do you? Several weeks ago a leaf started to brown and dry, since then it’s more of them. I’m not seeing an insect, but identifying that as an issue is not my strong suit (this coming to all of you). Help please. Thanks in advance.

I’m new to the community, newish to houseplants, but not to outdoor gardening. I’m having a hard time telling if my parlor palm has thrips. If it does, what are best ways to treat it, and I’m guessing I should treat the 3 plants next to it. (One is definitely having an issues of some sort as well.) Is this thrip damage?
