Hey everyone! I recently took in the ownership of a large snake plant that my mother bought. It was clearly dying and I knew I couldn't just leave it so I brought it inside and got to work on it. I noticed some webbing between the stalks and I concluded that it must have a spider mites infection. Any tips for getting rid of them? I've never had this problem before so tips and tricks are appreciated!

My pink princess philodendron isn’t doing very well and I’m not sure what to do about it, did I overwater it or underwater it or something else? I think I overwatered it, but I’m not certain. Please help if you know!

Anyone know what the cause of these black spots on the back of my pilea peperomioides could be? It’s only on older leaves, but the plant otherwise doesn’t seem to be showing signs of distress (other than that yellow leaf I should prune)— there’s steady growth from the mother plant and plenty of new pups!

Came back to my dorm to my poor boi in this condition on this side. Is something eating him? Is it a disease? Does he need to be reported into a bigger pot??? Help!

I recently got this ZZ plant and it just started turning yellow and dropping leaves. I repotted it after getting it and it has drainage. I’ve only had it about three weeks and have only watered it once, so I don’t know if it’s overwatering. Any idea what is going on?

Si this lil guy has been dropping leaves from the bottom. I’m not sure if that’s ok or if I should try to change something. I’m new-ish to this kind of plant and I worry I might be doing something wrong

Hello i'm new to the group. I had a Dieffenbachia given to me about six years ago. Two moves later and it now looks like this. I just repotted it before Christmas into a larger pot with gravel at the base for drainage and potting soil. Any advice would be helpful.

I have five agave Americana that are planted in the front garden bed of my house in south Texas. 4 of them are thriving but one looks like this. Significantly smaller with yellow spots. Any idea what’s going on?

My plant was thriving and now is dead. Does anyone know what might have happened? Is there any way I can propagate the leaves? Any advice/tips are welcome

Do nematodes work at removing fungus gnats from moss? I use PON so they’re not in my soil, I think they’re in my moss poles so I’m trying to figure out how to treat the poles.

Hi! I’m a new Monstera owner and recently I’ve noticed the leaves on my plant beginning to yellow and then brown. What am I doing wrong?

Split Leaf philodendron: A family member gave me this from a supermarket and was exposed to cold air. All the leaves (except two) have dry black edges and a couple with black markings in the middle of the leaf. I’m just want to make sure it’s not fungal or disease causing this. I’m hoping maybe cold exposure? Any ideas? Thank you

Does this look normal for a Plumeria in winter? I am in Houston area. I just moved it into the sunroom. I need to know if there’s something I should do to prevent it from dying while we get through winter, or if it should be left alone until it warms up. It has been a mild winter here until the last few days. Any advice welcome.

Anyone familiar with what might be happening to my monstera adansonii? This is only on two leaves and they are towards the top of my giant plant. It’s near a south facing window and has been for seven months. It’s treated with systemic granules and there are no signs of spider mites/webbing. I spray it down every other watering with insecticidal soap as a preventative. I water when it’s almost 100% dry - I tend to underwater, and I’ve read this could be because of that. It’s been growing non-stop too! The first two pics show the two leaves that are acting up. The last two pics show a pic of the giant plant plus one of three new leaves it’s currently pushing out.
