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?

My peperomia has been dropping leaves and I noticed a lot of the leaves have these small larvae on them. Most are still, but some are crawling. Unsure if whitefly larvae or some other type of pest? Thoughts?

Monstera deliciosa It has been struggling for a while with yellow leaves Drooping and was too big a pot. I was able to fix it all and it’s finally growing but I noticed that black part on the new leaf. Do I need to fix it or do something about it or let it unfold? Also I want to attach D shape moss pole to it. Do you think it’s doable right now? And where?

Hi all. I'm looking for help. I've noticed my inside plants keep growing mold or powdery mildew on the top layer of the soil. I'm trying to figure out what's causing it. Is it a lack of circulation or overwatering? Should I re-pot all my plants? Looks like the below.

Hello! I’ve had this plant for about 6 months and it recently has started to look like this? It was a propagation from a dieffenbachia that i have had for a couple years, but i have never seen it do this. Anyone know what is going on and how to save it? The leaves aren’t drying out but instead feel slightly mushy and are turning a brownish grey.

Hi-I’m new to the world of plants. I bought this parlor palm about a month ago on Facebook Marketplace. I’ve watered it twice since - the first time 24 oz of water a few days after repotting (which occurred the week I got it) and the second time a few days ago I watered till I saw a few drops of water through the drain hole. My moisture meter says it’s still damp/appropriately watered deep down. I’ve had a number of stems turns yellow/brown - i cut a few off and you can see others that have just turned yellow. I bought a grow light a week ago because I was afraid my plant wasn’t getting enough sun. Nonetheless, I’m still having problems. Any and all suggestions are welcome.

accidentally snapped the stalk of my money tree. It’s still intact but it’s for sure broken. Will the plant heal? What can I do to help it along? This was my first house plant I got several years ago 😫

Need help with my Birds of paradise plant and my painters palette plant. I brought them inside for the winter a couple months ago and they both started turning yellow and drying up on some leaves at the same time. I also have a yucca palm that doing the same thing. What could be the cause of this? Maybe they are getting use to the new environment? Cold draft? Underwatering?

For reference, this baby was moved to take a better photo. This is not where she lives. She sits in my bathroom window. Why have all of the leaves dropped? Is it fall time in my house? I seem to have a little bit of new growth at the top coming in but now we’re getting pretty leggy looking. Lol

I have tried growing mini cypress trees but they are quickly getting crunchy and dying. What am I doing wrong? The plants are next to a shaded window and watered twice a week which is when it seems to be dry. EDIT: just added extra dirt today but the soil under was watered today. Pipe cleaner is because its splaying out.
